I had an excellent experience with this window company from start to finish. They ordered the windows right away and scheduled the installation promptly. The crew was efficient and professional! Everything was completed in just one day. The new windows fit perfectly, and the caulking was done with great attention to detail. I’m extremely pleased with the quality of their work and would highly recommend them to anyone looking for reliable, top-notch service.

Denco Windows is also the owner of Denco Properties. Because of this (and they do not have a separate page), here is my review/experience with them, as I was told their staff oversees both departments. AVOID DENCO PROPERTIES AT ALL COSTS! This is a warning for anyone looking to move into one of their spaces. Highly unprofessional, disrespectful, and shady. Took our full security deposit without a valid reason. My wife and I used to live at their Pilgrim Square property in Germantown, WI. They took over from old management and from the beginning, they struggled with communication. Around the time our lease was set to expire, I reached out to see if we could get a new one and they did not respond. I reached out again only days before and they still never sent us one. Our lease expired and

If Denco is the New England Patriots of European Windows....Steve is the GOAT. I ordered 3 large tilt/turn windows from Denco. I was kept informed as they were manufactured and shipped. Steve worked with my installer to make sure everything fit perfectly. They are high quality windows. The screens aren't great but I took mine out, no bugs in Utah :) - If you like winning, go with Steve. If you like whatever it is the Rams did yesterday, maybe look elsewhere...

Fantastic service. Nick and co. replaced all of our windows about 7 years ago. We were surprised with the fair price and everything was done quicker than we were planning. The windows are still holding up strong and beautiful. Today we had an issue, a mistake on our part not knowing how the window tilt mechanism worked. I gave them a call and Nick remembered the job, and explained the solution. Even sent me a video within a minute of me calling to make sure I knew how it operated. He was clearly out at a job there were drills running, yet had the same friendliness and professionalism as the day we were discussing buying new windows. That's a level of integrity you don't see often these days. Above and beyond. You're in good hands with Denco.

After several weeks of battling no-show and delinquent contractors to quote me replacement windows, working with Nick was a breath of fresh air. He set up a visit to quote my windows within a couple days of calling, was prompt in meeting with me, and made the whole thing a hassle free experience. His pricing was very fair, and the work was done well. With out a doubt, he will be my first call next time I need windows.
