Good service, good prices 6/23/2016

I had one plate glass window and two double-hung windows installed and the installation was extremely fast! The service was great and there were no problems. I'm very happy with the installation and the quality of the windows and would hire them again. Their prices were competitive and they were lovely to deal with. more

Good product and service for the money; however, the service may not be the best 6/14/2016

Generally, my experience with Colorado Window Source through the sales process went very well with no real complaints overall--until we came to the installation. One of the installers left in charge of the job had little to no customer service skills. The individual in charge of my job I think was condescending, unprofessional, and didn't represent the organization well. I was at a point where I contemplated having him removed from the property. All in all, it was a good experience and the quality of product seems to be good. But, I'm still waiting on a replacement sash--it's been going on at least two months. All in all, I think they did a good job as far as being transparent. more

Great service and work. 6/7/2016

We had a snag almost right away with Colorado Window Source, it wasn't their fault but the windows arrived damaged. But I was very impressed with them, they got the parts and started working on them right away and din't stop until they got them the way they should be. I appreciated their hard work, they showed up on time and were very good at what they do. I would recommend them. more

Highly satisfied! 5/27/2016

Over the course of five years, we've had approximately 40+ windows in our home replaced by Colorado Window Source. They took out all of the old wood windows and put in new windows for us and the quality of their service is good. They aren't just slapping the windows in, they make sure all of the windows fit and if they catch a problem while installing the windows, they'll make sure to fix it before they leave so they won't have to come back. Their prices are comparable and the quality of their work is excellent. I'm a highly satisfied customer and will use them again in the future. more

Roofing Review--very positive 1/24/2016

I am very happy to recommend Colorado Roofing Source for your roofing service needs. They are very knowledgeable, professional and provided great service. They appeared on time and prepared for all appointments and service. They were able and willing to work with the insurance company to get us a fair result. They did the work timely, professionally and kept us updated on the status at every step. They even cleaned up the job site perfectly. They were great to work with. We are very satisfied and highly recommend them for your consideration on your projects. more

Excellent!! 1/3/2015

CWS was a great company to work with on my replacement window project from sales to installation. The process was painless. My project was complicated due to HOA requirements. Mark, the sales person, was very patient and flexible, Terry in the back office was very responsive regarding my order and install scheduling. The installation went well. Mike and his team were professional, clean and took pride in their work. I love my new windows and patio door! more

Great Windows Great Price Great People 12/10/2013

We had new Vinyl double pane windows installed almost 5 years ago, and by now they have paid for themselves. The upper floor windows are easy for us to clean as they are removeable from the frame. The installation was precise. The windows are as snug as the day they were installed. Everything was done to perfection in one day, including a large window in the front room. The install team was courteous, professional, and clean. They know what they are doing. If there were 6 star ratings, I would easily rate them at that level as well. more

Love It !!!!!! 11/29/2013

Colorado window source put in all new windows and patio doors on my house and I love them!!!! The whole process was easy. Chris came out and gave us a great price, the they came and measured and then installed them perfectly. Could not be happier with them. I would HIGHLY recommend them for anything! more

Customer service could be better 8/27/2013

We recently replaced our front door and sidelight; in my searches on-line I found a very specific Therma-Tru door that we loved. Colorado Window Source happened to be the closest dealer that could get us the door. We were very, very impressed with all of our interactions with them until we actually put down our deposit. Several weeks after placing our order, we received a call to let us know that our door would be arriving the next week and we scheduled a time for installation. The evening before the installation, we received another call letting us know that our door had in fact NOT arrived. We did not get any real answers on what had happened to our door and were told it might be in the next week, or it might be in a few weeks, but that someone would get back to us. We did not get another call until more than a month later, to let us know our door would be arriving in the next week and again cleared our schedules for another installation. The installation was not fully completed that day, and although he was going to come back the next day to finish, he did not actually return for 2 days. Even then, we had to wait another week for a sill-extender that someone "forgot" to order. We also ordered a door stain kit from CWS; we were required to pay in full before the order was placed and were told it would be a week or so before it would come in, and that someone would call us. Almost a month later, we still do not have our stain, nor any answers about where it is or when it will arrive. Although we do greatly enjoy our new door and side light, the experience of working with Colorado Window Source has not been positive and I can not imagine using them again in the future. more

Going back for more! 6/26/2013

We installed windows on the front side (SW facing) first because of the afternoon heat. WOW! What a difference the windows have made in those rooms! We also chose windows without the grids and LOVE IT!! We're going back to CWS to finish the back side of the house to get the full benefits of energy efficiency and the same quality products and service! Thank you CWS! more

I had a positive experience from showroom to clean up. 2/25/2013

Working with Colorado Window Source was a positive experience starting with the minute I walked into the showroom until they cleaned up at the end of the job. They replaced 14 windows and installed eight shutters for us. The installation process was very positive. They were on time, friendly, and did a nice job cleaning up. more

Excellent company to work with. Honest, timely and cleaned up afterwards. 2/12/2013

Colorado Window Source had the best price for the product and the team was great to work with-from the initial salesman, Steve, to the installer, Jim, and his crew. I would recommend this company. more

Great Windows, great price, and great installation. 2/4/2013

I received three bids before choosing Colorado Window source. These days it is very hard to fine a company that actually does what it says it will do. Colorado Window Source exceeded my expectations. They provided me with the perfect solution for my house (I replaced all the windows on my main level. I have a ranch walk out). The installers were fantastic and very respectful of the inside and outside of my home. The windows are amazing and create a wonderful living space. I highly, highly recommend Colorado Window Source!!!! more

Great price, products, and service 12/10/2012

I got estimates from three window companies and chose Colorado Window Source for the best products and prices. When the windows arrived and were installed, it was with the same high level of service! Way better than Pella, who gave me an inflated estimate by a rude sales representative, and way better than Anderson, with their high pressure sales tactics. From here on out, I will go with, and recommend, Colorado Window Source! more

Roof, Windows and Paint 12/5/2012

Have a brand new house that looks and feels brand new because of the great work done! Thank you CO Window!!! No more leak from the windows, roof is perfect and paint job is hands down best we've ever had! Would reco and use again in a heartbeat! more

Done on time and within budget 11/19/2012

Colorado Window Source helped me hold an order until my homeowner association gave final approval of the project. They made suggestions to improve the look of the house and offered a variety of choices. The sales person was friendly. The installers were clean and efficient. more

If you need windows, call these guys. 11/19/2012

Colorado Window Source gave me a good deal on the windows. The price was right, they were on time, and they did a great job. more

Exceeded EVERY Expectation 10/24/2012

I also am in the service industry (Realtor) and I come across trades all the time that I am asked to refer. I also could be described as having high expectations for people that I refer and work with. I refer lots of people everyday to my clients from lenders, to inspectors to roofers and landscapers. With that said I take giving a referral very seriously and expect the trade I refer to be top notch. CWS is just that - top notch! After exhaustive research on types of windows I finally stumbled upon Colorado Window Source and I am glad I did. This company understands service and the needs of the client. I was impressed from the moment I met Kurt for my bid. He was professional, on time and understanding of my project needs and budget. Believe me, I met with 7 other companies before CWS. He was also more knowledgeable then his competitors selling the same product (Amerimax Windows) It was absolutely vital to me that whomever I chose and entrusted for a major renovation on my house that they meet two criteria - Be Professional & Be Competent. I felt that it was just as important to pick the right window, the right company and the right installers. CWS again exceeded all of my requirements. And as an added bonus CWS was nearly 2k cheaper then their competitors. Once my project began it was clear to know that I had indeed made the right decision in choosing CWS. Their installers were just as professional, a joy to be around and did an absolutely beautiful job on my windows. They were careful and respectful of my time and my house. They were clean and on time and their work and craftsmanship was stunning. They went above and beyond in my opinion. As an added bonus Steve from CWS popped in and out from time to time to check in on the work and my comfort level. Across the board this is an A+ organization run by professionals that shoot strait and stand behind their work. They are great guys and exceeded all my expectations. I highly recommend them to everyone I know and when I am selling houses that need windows these are the "goto" guys. Don't hesitate in using CWS for ANY project. I guarantee you won't be disappointed! more

Job well done 10/24/2012

I just wanted to write a quick note thanking you for the great job on my new door. This project replaced the entry door unit including the door slab, two sidelights and an overhead transom window. The work was necessary because the original builder-grade unit had failed from dry-rot due to poor installation when the home was built. We were very pleased with the service we received from CWS throughout the project. Everything went smoothly, starting with the initial planning in your showroom where Chris demonstrated in great detail why the Thermatru product wouldnt suffer the same problems, all the way through the final installation and cleanup by Bret & Steve. The work was completed well within the estimated timeframe. The project management by Ashlea and her thorough communication made the entire job a breeze. CWS will be my first choice for any future work this home needs and I'm happy to recommend you and Thermatru to others. more
