"One Window At A Time did the work another company I hired couldn't do. Their arrival time was when they said and the job was completed in a timely fashion. I would highly recommend One Window At A Time to anyone that is looking for high quality windows at a better than fair price and workmanship second to none."

"Next time you walk by an egress window on one of these flipped homes - check out the workmanship - crooked, leaking glue out the sides, certainly no permit. I know this because I have witnessed it AND I called one of those "cheap" window people for an estimate (notice how they are ready at the drop off a hat and then drop out of sight when there are problems? The window placed by Egree Inc is perfect. Was it more expensive - not much more than as egress window placed in 2013 that was equal in quality. It was also permitted, inspected, and sits level without leftover glue seeping out the sides. Was there a wait time - not more than I would expect from any quality provider. I was kept informed on the timeline and the window was completed as promised. BONUS - the workmanship is guaranteed and the company will be around to stand behind the workmanship. Excellent work."

"We had the main windows done by Power Windows in 2021 and now we had them do the windows on our outbuilding and mudroom. The entire process has been great from start to finish. The windows are fantastic, keeps the heat out in the summer and cold out in the winter. The sales(Davis, Jack, and Brad) and work crew(headed by Gus) have been very up front and professional. I highly recommend this company."

"Excellent job on the window tinting project. The quality of the work is top- notch, clean precise and professionally done. The tint not only enhanced the look of the home but has reduced the glare and heat, just as I had hoped. Cassandra was respectful of our space and left everything spotless after the job was done. I’d highly recommend to anyone looking to upgrade their home Windows. Outstanding work with a fun personality!!"

"When we first reached out to Egress Windows Colorado, Giovanni got back to me on the same day. He came out the next day to look at our project and give us a quote. He was very knowledgeable and answered all of our questions. They ended up having a spot in their schedule so we were able to get our windows installed the same week. When Gerardo and his crew showed up they got right to work. They were efficient, thoughtful and did a wonderful job. Our new egress windows have totally changed the way our basement looks and feels. Thanks to the Egress Windows team! Highly recommend."

"Our window started leaking after a big rain storm and I wasnâ t able to isolate the source of the leak. Jason came out the same day and was able to identify the issue with the caulk around the glass. He answered all of our questions and provided a very reasonable quote which they came back to fix the following week after the window had dried out. We had a couple other windows we were worried about sealed at the same time. Great service and workmanship! I would recommend them for all your window and glass needs."

Windows questions, answered by experts

In Thornton, window replacement for a single window usually takes 2-4 hours, while replacing all windows in a typical home can be completed in 1-3 days. Custom window installations or specialty glass may require several weeks for fabrication before installation. Seasonal factors, like winter storms or high winds, can extend project timelines, so scheduling window repair or replacement in milder months is often more efficient.

Helpful?

In Thornton, start spring by inspecting windows for cracked seals or water damage left by winter. Summer is ideal for checking UV damage, cleaning tracks, and ensuring screens are intact. In fall, reseal caulking and add weatherstripping to prepare for cold snaps. During winter, monitor for condensation and drafts. After major storms or hail, promptly check for broken glass or frame damage to maintain window performance.

Helpful?

Completing window service in Thornton offers immediate benefits like improved insulation, reduced drafts, and better indoor comfort during rapid weather changes. Long-term, homeowners enjoy increased property value, lower energy bills, and enhanced protection from UV rays and hail. Upgrading to impact-resistant or energy-efficient windows also reduces outside noise and can help your home withstand Thornton’s frequent wind and hailstorms.

Helpful?

For window service in Thornton, vinyl and fiberglass frames are popular for their durability and energy efficiency, especially during Colorado’s freeze-thaw cycles. Double-pane or triple-pane windows with Low-E coatings and argon gas provide superior insulation. Weather-resistant caulking and rust-proof hardware are essential for protection against Thornton’s dry climate and sudden temperature shifts, while reinforced screens help prevent damage from local wildlife and debris.

Helpful?

To keep window service in Thornton safe for families, always block off work areas and ventilate well during repairs. Opt for tempered glass and window guards to prevent accidents with children. Cordless blinds reduce strangulation risks, while reinforced screens and secure latches protect pets. Consider installing windows that open from the top or have limited openings to increase safety, especially in multi-story homes.
