"Excellent experience from start to finish! The team was professional, friendly, and arrived on time. They did an amazing job cleaning our windows—they're absolutely sparkling, and I didn't realize how much brighter the house would look afterward. They were careful, efficient, and left everything clean when they finished. I highly recommend this company to anyone looking for quality window cleaning and outstanding customer service. I'll definitely be using them again!"

"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."

"Ray the owner was on time, worked fast and did a great job. Our house will sell better because of our sparkling windows. He was friendly and even washed the two little windows on our shed for no charge that were not included in the bid.Our bid also included cleaning out our window wells and cleaning those windows. He did an excellent job. His prices are low. He is a veteran and hires veterans in his business. I would definitely recommend this company for windows and gutter cleaning."

Windows FAQs, answered by experts

Glass block windows are energy-efficient because they are much thicker than traditional glass panes, making them better insulators. They are sealed airtight, which prevents drafts and stops warm or cool air from escaping, helping to save money on heating and cooling bills. Unlike traditional windows that can be opened and closed, sealed glass block windows eliminate the potential for air leaks. For proven efficiency, look for options that are Energy Star rated. The cost for energy-efficient glass block windows is typically around $400 per window, which may be higher than standard windows.

Window washing usually refers to cleaning dirt and other debris off of the exterior of your windows, while window cleaning is a much more involved process that addresses the outside and inside of the glass, as well as the interior components. Window washing is more to improve the aesthetic of your windows, while window cleaning can improve performance, reduce the risk of damage over time, and even improve your home’s energy efficiency.

Shatter-resistant glass will ensure that even with a high impact, the glass of your window panes is less likely to break. If you’re looking for a more low-cost way to prevent vandalism, the most traditional answer would be to board up windows with a strong plywood sheet. Adding security cameras is also a surefire way to ward off potential vandalism. 

Depending on the window style and your home's layout, you can install replacement windows from either the inside or the outside. Many installations are done from the inside because it allows for better access and weather protection, but some exterior installs are easier for certain types of siding or trim. The key is choosing the approach that gives you the best access to the frame while keeping the existing structure intact.

Replacing basement windows can be worth the cost if replacement is necessary. If your windows are leaking and leading to water damage in your basement, it’s absolutely worth replacing them. Similarly, if your basement windows are no longer insulating your basement or pose a security risk, you need to replace them.

In some cases, you may be able to save money by repairing a window instead of replacing it. A contractor can help you decide the right course of action.
