My new windows were installed at the end of August. I won the windows in a contest, so didn’t expect much customer service. I was pleasantly surprised! They worked with my crazy schedule and Clyde even came to my home in the evening, after work, to measure for the windows. Jeff was my installer and he was awesome! It took him, literally, all day due to issues with removing the old windows and he never complained and was pleasant the whole day. The windows are really nice and look great!

I found Windows America through Home Advisor and only planned on getting a quote for a few cloudy, old windows. I was worried about a high-pressure sell so I checked online at Home Depot for a base price to compare. It turned out that Windows America was able to quote a price that was competitive with the basic Home Depot product but much better quality and with a lifetime warranty. Even though theirs was the first quote, we decided to purchase from them and are so glad we did.

The installation process was quick (within a few weeks) and they took the time to really do a good job with caulking, insulation and replacing rotted wood trim. I’m so glad we chose Windows America.

I can’t recommend them enough!

Keith went above and beyond for us. The company was great about working with us and with our tenant. Thanks so much!

Good price too 🙂

After 26 years in our home, we decided to replace our front 3 windows with a bay window. Our sales person Keith was very knowledgeable and very helpful. The installers were fantastic! They were precise and very professional. They were also extremely detail oriented. My husband customized our baseboards and door frames and they matched it perfectly! I would highly recommend them!

Just had our windows installed yesterday. We found New Windows through a special group rate with our HOA (mandatory community upgrade), but there was nothing cut rate about the experience. Our salesman Keith especially went out of his way to make sure we were taken care of every step of the way (even working with us to set up some creative financing options).

The crew of four were all professional and courteous, and very knowledgeable. Anyone who thinks they can save some money and do this job themselves, I would dissuade you. Our building is circa early 80’s, and just cracking out the old windows created lots of unforeseen damage and complications that were taken care of handily by the team (they also assured me that I was by no means their most difficult project). We’ve had years of drywall water damage from the cheap old windows which they repaired, as well as added flashing to prevent future damage. They explained everything very well.

I could go on all day about how great they were, but let me just finish by saying they left my house cleaner than they found it (although my one word of warning would be to cover electronics, etc. just in case. Dust gets everywhere and they can’t possibly cover the whole house), and waking up this morning to our bright, clean, white windows (old frames were dark bronze and hideous) was like having a new house.

Would not hesitate to recommend New Windows. I trust their workmanship and dedication to customer service. At no point did I feel forgotten or taken for granted. I especially like their warranty policy — they are a representative of the manufacturer, so if anything goes wrong I don’t need to wonder who to contact. Every company should do that.

Mr. & Mrs. Lundeen were kind enough to transfer the patio door to my daughter and son-in-law’s home. They appreciate being the recipients of something they needed to much and their house is more comfortable and secure as a result.

Your company replaced all the windows and the backdoor in my town home on February 20. Vinylmax was the manufacturer. My handyman told me later it was the cleanest job he had ever seen. I had nothing to compare the installation to.

Sales Manager, Keith Nisonoff, provided me with a good price and was able to give me some extra benefits by tagging on to a large order going in at the end of the year.

The backdoor is terrific! The Thermatrue door shuts very snugly eliminating the gap and draft I had previously.

The windows are evening out the temperature differences I previously experienced in the house. In addition, much of the solar heat has been lessened. Facing south, two rooms were blasted with sunshine. Now, the rooms are comfortable.

Two missing screens were inserted a week or so after the installation. That man discovered that one of the windows wasn’t closed completely. He made adjustments so that it did.

I’m sorry I don’t remember the names of the installing team. There were five men, all of whom were polite, tidy and quick. I’d like to especially thank them.

I would definitely recommend your company to anyone wanting to replace windows.

Windows America was fast and efficient. The new windows in my place are beautiful. At first there was a misunderstanding….the sills were supposed to be replaced (which had not gotten conveyed to the work crew). The situation was immediately remedied once it was brought to their attention however. I would recommend them!

New Windows for America in North Denver, just replaced 8 windows and a sliding glass door in our house. Jeff and Russ teamed up to do our install in one day. To say they and their teams did an excellent job would be an understatement! Everything about this install went without a hitch, from the first sales call thru installation, everyone we met were very customer oriented and friendly.
We are very pleased with our new windows and our choice of New Windows for America to do the job.

Over the past several years, we have been replacing our old, energy-inefficient windows with Windows for America product. Yesterday we had the final window replaced! We love the windows, and they have made a huge difference in the comfort of our home. Windows America also stands behind their product. On the rare occasion that we had an issue with fit or seal, they were prompt and courteous and took care of the problem right away. There aren’t a lot of companies these days who do it right–Windows for America is one that does!
