Door and Window Installation

Colorado Classic Windows takes pride in being a full-service company in Denver. That means that our scope of work includes product sales, complete door and window installation, and service for our installed products.
It’s not uncommon for a homeowner to decide that their project will include replacement windows, doors and sun screens. Working with us on all phases helps to ensure that each phase is scheduled and completed within the appropriate time frame at a consistent level of excellence. Our goal is always to keep the disruption to your home life as minimal as possible.

At first meeting Preston Lewis in our living room we were immediately impressed with his professionalism and obvious experience. He made us feel very at ease about such a large and expensive investment in our home. He presented a siding product that no other salesperson offered us (we spoke with a half dozen salespeople); oddly enough it was the product that made the most sense to us. By the time he was done with his presentation and bid submission, my wife and I both were equally impressed with his ability to establish himself as our trusted advisor for this project. Throughout the process he kept reaffirming our confidence in him and his organization. His commitment to customer service and regular communication kept the whole process simple and us at ease. When installation day came, his crew arrived on time and set about their work in an equally professional manner. When issues arose with more than one solution the crew spoke to us and included us in every decision. One of the areas of concern for us is our backyard gate and our dogs getting loose. The crew was very diligent about working with us to avoid this. Overall, we would be happy and honored to recommend Colorado Classic Windows for any home improvement project.

We had new windows installed in February 2011. It is quieter and the Xcel bill is lower than it was. The installers did a great job and we are happy with our choice.

My wife, Charlie, & I have been owners/resided here at W114 Circle since December, 1992. A few years ago we replaced windows. Colorado Classic Windows has been a blessing indeed. Our heating containment shows up in savings on our Excel energy bills and our cooling costs are noticeably improved. To me, the “proof is in the pudin”. We recommend Colorado Classis Windows, Preston Lewis. They satisfied beyond our expectations.

I hired Colorado Classic Windows to help me with upgrading the windows and patio door in my rental home. I wanted to make sure that the job was done right since a family member is renting the home from me. It only took one day and the crew was very efficient and careful while they worked. The price was right and the windows look great. My tenant is happy too (which is good since their family). They were very easy to work with and I appreciated their comfortable but professional approach.

Preston from Colorado Classic Windows was extremely professional and returned my initial call on the same day. He came out for a bid within a week and gave me an excellent quote. The install took only two days and both installers were competent and curious. The windows have worked out great so far. They actually wrapped the window with aluminum so that I will never have to paint the window frames – the old frames were beyond painting.
We already notice how much cooler it is in the house this summer. The only small issue was the clean up after the install. There were some chards of aluminum left over that could have been dangerous.
I highly recommend Colorado Classic Windows. They are consummate professionals

CCW are some of the most stand up and trust worthy guys in the business. I had six different companies come to my home and give me a quote for new windows. With CCW’s I was not only able to get the job done for less, but I also got a better window than the other companies were offering. I highly recommend this company. All of my neighbors want to know who did my windows. Not only do they look good but they seem to be extremely well insulated as well.
Ryan M., Boulder
We had CCW install one brand new window and relocate an existing window in another wall of our home. He had everything from the demolition to the drywalling scheduled down to the “T”. We were very pleased with how well everything went and the final result was nothing short of exceptional! The new windows add not only character but value to our home. We highly recommend Colorado Classic Windows and plan on using them when we replace our two patio sliders with new swing style. Preston’s a man of his word and stands behind his work. You won’t be disappointed if you hire him. Thanks Preston.

It was a true pleasure working with Preston and the entire CCW team. CCW came highly recommended from some of our neighbors that also had windows replaced that were damaged in the destructive hail storm in August 2013. We had a number of window companies provide bids, but we felt most comfortable with Preston. Preston worked tirelessly with the adjuster of our insurance company who was very challenging to work with. Initially, the insurance company was only willing to replace the windows on two sides of our home, but Preston was able to come to terms with our adjuster to replace all the windows. The entire CCW team was fantastic to work with. Each member of the team was very professional, friendly, and they all took great care with our home and belongings. They also were very sensitive to being as clean as possible throughout the project. We would recommend Colorado Classic Windows without hesitation.

I was very impressed with the response time in all aspects of this process – Preston was very prompt, polite and very efficient. He has installed a great product at a very reasonable price. Highly recommend him!
Gail G., Denver
Our new windows from CCW are fantastic. It is the middle of the summer and our house is now a comfortable temperature, and our swamp cooler runs significantly less. The installation was quick and professional.
Candice B., Arvada
Working with Preston Lewis was an outstanding experience and I would whole-heartedly give him a rating of 6 (out of 5 possible) if I could! His bid on the project (a custom job involving a grouping of 5 windows in an arch-configuration) was very competitive. More important was an immediate sense of his expertise and a feeling of honesty and trust. Instead of just window replacement, the job was much more complicated; there was extensive water damage requiring tearing down and rebuilding the entire wall. The project was done expertly in 100 degree heat. They stayed late so as to finish on time. Room prep and clean up were done with care. I am very pleased.
