The folks at Colorado Window Source did a terrific job with our Hardie siding. We upgraded from hail damaged vinyl and the additional cost was worth it. You know more severe hail storms will be coming. The price was fair, the communication was solid, the customer service is outstanding. The installation crew did real quality work.

The folks at Colorado Window Source did a terrific job with our Hardie siding. We upgraded from hail damaged vinyl and the additional cost was worth it. You know more severe hail storms will be coming. The price was fair, the communication was solid, the customer service is outstanding. The installation crew did real quality work. I have a neighbor with Hardie from another company and our installation is much better. There was a real focus on getting the details right. They are responsive and careful. We recommend them highly.

Called to get 4 windows replaced from hail and tornado damage but there is a 5 window minimum. I told them that I was a previous customer but that did not matter, must be 5 windows to make it worth their time. Pretty sad customer service

Do NOT use Colorado Window Source for your window. It's impressive how bad they are at every aspect of their job. The install was HORRIBLE and ugly, and it took them over a year to do what they said they would do in 6 weeks. First, they gave us an estimate of about 6 weeks for the window install. I give them a deposit, and they essentially disappeared and were impossible to get ahold of. A year ... More
Do NOT use Colorado Window Source for your window. It's impressive how bad they are at every aspect of their job. The install was HORRIBLE and ugly, and it took them over a year to do what they said they would do in 6 weeks. First, they gave us an estimate of about 6 weeks for the window install. I give them a deposit, and they essentially disappeared and were impossible to get ahold of. A year later, the windows were still not in. After about a year, we were finally scheduled to get the windows in. But the patio doors that were also to be installed were not ready because they forgot to order them. The patio door took another 2 months to arrive. When they did the install, the quality of their install was jaw dropping ugly and terrible. Their caulking work looked like a 5 year old who used bubble gum. I ended up hiring someone to remove all of the caulking, and re-caulk the windows properly. This was over a week long project and cost about 2k. Do not, under any circumstance, use Colorado Window Source. No wonder why they have such bad reviews. Less

We ordered doors 12 weeks ago and CWS scheduled a time for measurements. The guy never showed up and when we called his number, it was disconnected. We had to reschedule. 8 weeks later, we followed up with Paolo to see if there was an update on timing for installation of the doors (we are expecting a baby and made it clear to the team that we’re on a tight schedule).

We ordered doors 12 weeks ago and CWS scheduled a time for measurements. The guy never showed up and when we called his number, it was disconnected. We had to reschedule. 8 weeks later, we followed up with Paolo to see if there was an update on timing for installation of the doors (we are expecting a baby and made it clear to the team that we’re on a tight schedule). After no response from Paolo for weeks (we followed up every few days), we finally heard back that the team could install on Labor Day, which surprised us and we asked if the team could work on a holiday. Paolo responded that they would definitely work then, only to then call us Labor Day morning to say they couldn’t do the job that day because the warehouse was closed. We had to reschedule for the following Tuesday. No one showed up. We called multiple times to see where the installation team was and no one could give us an answer. At this point, we'd been stood up THREE TIMES by CWS (they told us we need to reschedule again, which is difficult and stressful with the baby arriving and because they have given us many reasons to believe that they won't show up). We rescheduled for Friday, 9/15, (my due date). The men who showed up seemed surprised we were leaving, even though CWS told us we had to be out of the house due to lead paint. This did not inspire any confidence that the project would be handled in an appropriate way to mitigate lead dust and paint chips, which is extremely stressful with a baby on the way. We left and came back to our house at 3:00pm (they estimated 2:00pm to be done) to be told that the garage door they had ordered wouldn't fit correctly, that they wouldn't be able to finish the back door that day, and that they weren't able to start the front door. In addition, the new garage door has scratches all over it. We have not received any updates on what will happen with the garage door, and can't get a hold of anyone at CWS to understand what they will do to make this right. Photos show the interior of our house looking at the garage door and the scratches on the new garage door. Less

Don’t use this company as they are basically a middle-man installing other window company products which they will not service, warranty or replace! Buyer BEWARE!

I'm honestly a little surprised to see as many positive reviews here as I did. My experience has been nothing more than extremely frustrating. I worked with Leo back in April/May of 2022 to select and order a new front door and clearstory window for my house. We paid our initial deposit for the order at that time and still have not received any of the product. We are just told things are delayed. To now have been waiting for 8/9 months is unheard of. Most recently we were told the door is in and the window is not and that they would do a split install to which to date still has not been scheduled. Emails, Inquiries are not responded to and when they are it's "we will follow up with you" and then nothing ever comes of it. I will adjust my review rating and comment at the end but I would recommend being very careful. So just to update everyone, they came out installed the door, broke pieces of it, said they would order new parts never heard from them again. I had also ordered a window that was suppose to go above the door, never came in, never heard from them. I would recommend never using this company. Leo is a gray salesman and makes you think he has it all covered and it’s all a scam. Buyer beware. Less

Very good service and excellent quality windows. Offered best price of five quotes I had received. One window was damaged in shipping and was quickly replaced. Very satisfied with the installation and cleanup

They did an excellent job installing my basement windows.Thanks to their great measurements the windows look great and fit perfectly. I highly recommend them and would definitely use them again.

I had some hail damage to my house last year and I was lucky enough to hire Leo and his team to install 9 windows and a sliding door. I am really pleased with their work. My insurance company was giving me problems on the reimbursement. Leo provided the commentary that assisted in a reimbursement of 100% of my request. He even found additional damage on a door that was missed by insurance company. He’s an expert. I purchase Anlin windows which I thought would be the same as my previous windows. Boy, was I wrong. There is a night and day difference in amount of UV rays that these windows filter out. This should really help out on my AC bill. Lastly, I need to give recognition to the installation team. They did a great job and completed the installation of everything in about a day and half. Colorado Windows Source are good people. I highly recommend them. Less

I was very pleased with everyone that I interacted with at Colorado Window Source. They worked with me to accommodate the tenant in one of my units and completed the work on that unit in the time promised. They showed up on time, were professional and let me know if there were any issues while they were installing the windows.

Amazing company and even better people. Super professional and did a super job.

Wow!!! Colorado Window Source are amazing. Super responsive, professional, accurate service from a really great team of people. We’re flexible to work around my schedule. I left for work with old windows and I came home to new ones. They didn’t leave a single trace of them being there either. Would definitely recommend to anyone and I will most definitely be using them in the future!! A+++

Colorado Window Source replaced 36 windows for me in a commercial building. I was very impressed with the entire process. Their pricing was very reasonable. The service was great. The windows look amazing! I would highly recommend Colorado Window Source for commercial or residential windows.

We worked with Leo who is very knowledgeable about windows, installation and features. He was great to work with and helped us make choices that we probably wouldn't have considered and we're really happy we did. No more hanging out of the upstairs windows to clean them!

We replaced our old aluminum windows and sliding door and after shopping around quite a bit we found CO Window Source was the best value. The installers did a great job and we couldn't believe how quickly they were able to get the windows replaced! We couldn't be happier with the end product!

We have worked with these wonderful folks for many years. Many of our clients have too. A kitchen window we replaced (old metal one) leaked cold air so bad we had to wear a sweater. Now the temperature near the window is only 1-2 degrees different from the rest of the house SO happy.

We worked with Leo D. From this company. We started the process in March. The pandemic hit. We started the paperwork in early April. However, we had to have the paperwork redone several times due to wrong address, & wrong style of windows-twice. Signed the contract that was finally correct in early May. The contractors who came out were great except for having to ask several times to wear a mask. The quality of the work was great. However, when we did our walk through our bathroom windows was not tinted as originally discussed. It is now February, our windows were done in late July and we have still received no follow up as to when this will be corrected. On top of that I had to ask several times for a receipt to show we paid. We were Told we would get a warranty and apparently that just comes with the windows purchase but there is in fact no actual warranty paper to read and refer to. Overall, I had to purchase some fake stained glass windows covering to cover the bathroom window and have had zero apology or follow up from not having the correct frosted windows. The service was awful, the quality of the workmanship is great. Not worth it though. We’re currently using another company for the second set of repairs and the communication is much better this far.

DON'T DO IT! You may think it's a good idea, but you'll regret it deeply. I wouldn't allow Colorado Window Source anywhere near my house for any reason ever gain - not even if it were on fire and they were the only people there to rescue our family or animals. AVOID Colorado Window Source with every ounce of your energy. This is one of the worst decisions I've made in my life and I've made some bad decisions throughout. The first meeting will leave you feeling as if you're in good hands but once they have your deposit, game over. You're going to get the worst of humanity once you've given them your money. The installers are sloppy, leave messes, don't clean up after themselves, throw tools on furniture, they don't show up on time, fail to follow through, and they lack thoughtfulness and respect, they don't cover anything or protect the paint on walls or the trim, and they're unprofessional, disrespectful, and rude. They do not respect homeowners or your home. This was an epic fail on my part. I should have vetted them better and prevented the installers from ever entering our home. Less

Best windows to insulate and reduce noise.

They did a great job replacing our old aluminum windows! Very fair pricing compared to other estimates we got. Fast work installing them, too. Only trouble we had was with the city building inspection, which was an issue with the city's process.

After getting a number of quotes, I decided to with Colorado Window Source because they were very informative and to the point. I did not have to deal with pushy salesmen.

Excellent attention to detail with great suggestions for enhancements!

Great experience. Windows have been awesome and insulate very well as our cooling bill has been much less than before. The installers did a great job as well and made sure the process was thorough and complete. If I could do it over again, I would still have Colorado Window Source install the windows. Highly recommended!

These guys go out of thier way to do a great job. Seamless and we never worried about anything, they are extremely organized and great attention to detail. Recently this week they put windows in a duplex I own and it was quick and precise and they even fixed something I didn't even ask them to do. Love all of the crews, very nice and respectful and you would not even know they worked here it was so clean after they finished, except that we have these beautiful windows.

From the salesman, Victor, to Mitch's installation team and all the way to the office manager, Leo, this company has been professional, helpful and fantastic to work with. I will absolutely use them on my next project!

I had windows installed from Window Source in December 2017. I was very pleased with the quality of installation and the windows have performed very nicely. If you want to get windows at a reasonable price that are high-quality, go with Window Source, you will be happy!

We are delighted with our new windows. They were installed in a timely fashion. The price was right. We now have a warmer upstairs than ever before. We will be interested in seeing how much this reduces our heating and A/C bills in the coming year. I am sure this installation will pay for itself. We also love the new modern look. What a nice improvement for our house.

In my opinion, when someone spends over $10,000, that company should at least follow-up with their customer to find out if anything else is needed and to verify satisfaction with the product and the service. On the afternoon of installation, the manager of the crew called one of the installers to say he was coming to my property to inspect the work. He never showed, and no explanation was given as to why not. No one from the company ever asked whether I was satisfied or not. Lastly, I paid the final balance due on the same afternoon of the installation. However, 30 days later, I received an email from the office asking me when they would receive payment. After I provided a copy of my check, which had been cashed by them a month prior, they just said "ok" and agreed that I didn't owe them anything else. No mention of being sorry for cashing my check--but not recording the payment. Everyone makes mistakes, I don't have a problem with that, but I would have appreciated them apologizing for their mix-up. Less

Colorado Window Source Denver is an amazing company. Scott came to a rental property we have and fixed a window that was installed 10 yrs ago. He was extremely helpful. Colorado Window Source will be the company we will utilize for our Denver properties.

We had a custom sliding patio door installed by CWS a year and a half ago. The project was difficult because of significant damage that existed from water leakage and carpenter ants and CWS did address those issues well. However, the patio door was not installed correctly; I discovered this as I could see the door leaking on my exposed subfloor waiting for repair with a flooring company. CWS did respond quickly to that and I ended up having the Amerimax engineers down to review the door and state that the door was not installed properly; they corrected the issue. I was livid the door was not installed properly and caused further delays on finishing the project. Additionally, a leaking backdoor was what lead to the significant damage previously there and cost us an extra $6k to repair. If our subfloor were not exposed, we would of been in the same situation in a few years and having to make costly repairs to our home again. Additionally, as part of the project, our entire back deck was removed and we agreed to have CWS install a new Trex deck for us (before we knew the door was not installed correctly). Scott and his designer/installer came out for that and wasted an hour of our time designing our deck and then we never heard from them again. I even sent numerous follow-up emails to get the quote and get scheduled to have our deck installed in just a couple months. Instead, we were left with the giant mud pit they created as part of all of this and ended up installing a paver patio on our own. Now, we are having all the windows in our home replaced and I didn't even give CWS a chance. I learned from our experience with CWS and found a company that only installs Amerimax windows and keeps the same installation crew on salary; no random contractors. Also, the sales guy, Chris, at CWS told me I would need to replace my plantation blinds with new windows, which is a lie. My current window installer said that is not the case; CWS sells blinds so they would of made me replace expensive blinds I wouldn't need to in order to make an extra buck. Less

I spent a very large amount of time interviewing window companies and windows before choosing CWS. They came in with a higher line window (Vanguard) at a lower price!! It almost scared me away (too good to be true?) but they were the real deal. the business model they use is best quality job at lowest possible price. Tisha was extremely patient with my l o n g email and phone communications. I was very nervous as windows are not cheap and this was a good chunk of money for me. Mike came out to measure and we got all the ducks in a row, ordered the windows and set up an install date. The installation crew (Mike again) came out and got down to business. They were fast and professional; cleaned up well after themselves and were conscientious about my property. We had one small problem that was important to me. One casement window opened in the wrong direction. Scott, an owner, REFUSED to accept my final payment until the new window was ordered, manufactured and installed at no extra charge. I am impressed. We plan to replace our porch and basement french doors soon with Vanguard sliding doors. Wanna bet who I will call first! The Vanguard windows are a better quality window. I have noticed that they are MUCH MORE QUIET than the original double pane windows were. I also notice that the heat of the sun through them is noticeably less. I am not sure but i feel that the furnace is not coming on as often now that the November weather is here and when I touch the window frames they are not cold even when it is 30 degrees out. Very happy with these windows and the installer. Do yourself a favor and make them one of the bids you get. Don't go with the companies that you see constantly advertised. They are good windows but FAR more expensive. I think you will be please with Vanguard windows and Colorado Window Source as your installer. Less

My wife and I are really glad we used Colorado Window Source. Not only are they great windows, but the installers paid attention to details and cleaned up after when they were done.

Great experience...Scott was great. Answered all my questions; very prompt, always available. Crew was great. On time, very clean...cleaned up each night. Completely clean after job was finished. Added an extra garage vent; fixed existing gutter problems. Highly recommend them.

After windows getting reinstalled because the first time they were not installed correctly, I am spending the day cleaning my entire house due to massive amount of dust inside and debris outside my house from the work they did. I gave them 2 stars because they did eventually come out and fix the issues. I cannot recommend this company.

The guys at Colorado window source were great. They came out right after I called. They worked with my insurance company to make sure everything was covered. They did my roof, gutters and painting all in 10 days. No issues.

We would definitely recommend Colorado Window Source (CWS). We had 7 storm damaged windows replaced. Paolo D. came to our home, explained all of our options, and their great warranty. We had other estimates, but, after working with Paolo, we knew CWS was the company to go with. Jim and his great crew installed the windows today. They did a great job!

We recently purchased 28 window coverings provided by CO Window Source. The design advice we received from David Wienecke was perfect and the installation from Deno Burgess could not have gone better, including removing all the debris.

Colorado Window Source installed 23 windows in my home and did an amazing job. My sales consultant, Dave, was super helpful and involved in every step of the project.

We bought a home that needed new Windows through out. 21 Windows. After meeting with several company's we went with CWS. They did come highly recommend from a coworker but I did not have the same experience. I believe the Windows we chose are decent but the installation was done poorly. I could write a long review explaining all the negative but to the point this company is horrible. From the sales, owners and install team. I had issues/arguments with all of them. As soon as I signed the contract they were different people. The most expensive project in my home remodel and it was the worst experience ever. Everyday I curse these Windows. Please shop elsewhere. Pay a little more and get quality Windows and installers. Less

We had 5 windows installed through Colorado Window source. They accommodated our requests, were timely and professional and their owner Scott personally took care of all the paperwork required. The sales person Steve was a pleasure to work with and not too pushy. Gave us a competitive price. Their installers Jim and Bill were patient enough to answer all our questions and took extra care in meeting our HOA requirements. Their Dry Waller - Enrique wasn't up to the mark and they lose a point in my book for that. We plan on using them again to get window work done on one of our rentals. Less

I did a lot of research into companies around Denver to replace our rear patio sliding door. I was happy to chose Colorado Window Source based on their high ratings, friendly professional staff, and use of quality products. They stand behind their work and materials as well as are prompt with all appointments/followups. The price was competitive and we truly love our new upgraded door! They are built in Loveland and when completed Tony came out to install it. He is a craftsman with attention to details and quality. I will post followup reports as they continue their one year inspection on the door and installation. A+ all around. I will be looking to these guys for further window upgrades in the near future.

We have gotten new windows and doors from CWS and then got new siding last fall. Very pleased with their products and excellent customer service.

Leo and Dave have been a pleasure to work with through the decision making process, and the installation of my new roof and patio windows. I've been in real estate for 19 years, and have them at the top of my referral list for my clients!

Excellent sales, service, and installation of all our windows. Colorado Windows also managed our roof replacement, siding repair, and exterior painting. Best paint job we have had

We just had our windows replaced on Friday (3/4) and could not have been happier we chose Colorado Window Source. Paolo came to give us an estimate in December. He was very personable and professional and answered all of our questions. Our order came in quicker than expected and we booked our install shortly after. The installers arrived right around the time proposed and immediately got to work. Originally, the job was estimated to take about a day and a half - we had 11 windows and a sliding glass door replaced. The installers stayed until the job was finished on Friday. Our overall expectations were exceeded - I highly recommend Colorado Window Source. Less

If there are any concerns, they are addressed right away with excellent follow-up to assure satisfaction.

Several years after our windows were installed by CWS we were having trim work done on our house and our contractor noticed that almost all of our windows had no insulation around them.

Several years after our windows were installed by CWS we were having trim work done on our house and our contractor noticed that almost all of our windows had no insulation around them. The space between the window frame and the stud was left open when the new windows were installed leaving the 1/2" drywall inside of our home and 1/2" trim on the exterior of the home as the only barrier between the elements outside and the inside of our house. What's the purpose of new windows if during the installation process these spaces are going to be left wide open? Good question. I called CWS and spoke to the owner of the company and when I explained the situation he noted that the installers use an insulating gun that only allows them to fill gaps that are 3/8" or larger on the outside in order to allow the nozzle to fit. Unfortunately, most of the exterior spaces are smaller than that dimension. When I pressed him on the subject asking why don't they use a different nozzle or process for filling these critical spaces with insulation he became agitated and said he'd send an installer over with $70 worth of insulating foam spray and fill all of the gaps. Why don't they do that in the first place? Great question. We ended up having our contractor who was doing the trim replacement insulate around all the windows that the CWS installers failed to do. The windows themselves appear to be OK but it really shows the poor commitment to quality and poor workmanship that CWS delivers. When you're spending thousands of dollars on this home upgrade I'd expect the company to ensure these important details during the installation process are taken care of otherwise it really defeats the purpose of new windows when you have cold air streaming into your home around those uninsulated areas. In the end if you're looking for replacement windows in your home my opinion is to do yourself a favor and look elsewhere. Less

I had a hail claim and met with Steve about our windows. They were very easy to work with and provided us with an awesome window that priced comparably with what the insurance company was paying which was a huge worry for us. They were knowledgable and courteous which we appreciated. I had some poorly installed windows that where not part of my claim which needed work. The windows were measured wrong originally and I asked for a quote to redo the trip and flashing on the outside. The Rep stated that was not the appropriate action that needed to be done as the windows were the wrong size and covering up the gap would be considered poor workmanship and they would not attempt something like that. It would eventually lead to leaks etc. I stopped and thought for a second and came to the conclusion that these guys had a very strong pride of workmanship and instead of doing whatever to get my business they took a stand and I totally respected that. Other window companies that I had look at my windows all said they would redo some trim and add caulk to make me happy. I hired Colo Window Srce and the windows look awesome and we are very satisfied with our decision. Less

Colorado Window Source is the right way to get your windows done!! They know and understand windows. They are very helpful with selecting the right window for your home. Everyone is very professional and extremely knowledgeable. They take great care with their installation and have a Tru Warranty Inspection program for the 1st year after the installation. I would highly recommend them!

Worst experience with a contractor and company I ever had. Window seals tilted in toward house - unbelievable. Over caulked gaps rather than cutting trim to fit. Caulked over drains that sit in windows to allow for drainage from windows. Didn't caulk nail holes. Never walked around the house for a final inspection.

Worst experience with a contractor and company I ever had. Window seals tilted in toward house - unbelievable. Over caulked gaps rather than cutting trim to fit. Caulked over drains that sit in windows to allow for drainage from windows. Didn't caulk nail holes. Never walked around the house for a final inspection. Missed or poorly caulked around several windows. Cracked several interior frames and never replaced caulk. My 8 year old son caulks better. Glass sliding door had large gaps at base. Once I committed to the sale they treated me poorly. The windows actually failed inspection and would have failed again but I decided to do the work myself. Installers told me that the caulk they use lasts forever. The owner never worked with me to try to correct obvious errors and was verbally abusive. The job was NEVER done to my satisfaction. I replaced over 20 windows. This was done in Spring of 2014. Less
