"Keith worked with me for about 3 months before I decided the final project. Keith was very professional and patient. He gave 3 estimates for which to choose from. He even hired a designer to help with the colors and placement of the panels. Work was started on time and it looks wonderful. I would highly recommend GS Exterior Experts."

Customers say: Quality work

"I had great service from start to finish with Bruce. I highly recommend using One Window at a time. Bruce listens and understands his customers concerns and explains thoroughly the installation process from start to finish. An install technician, named Mario did a fantastic job with my install, he arrived on time and cleaned with each step to ensure zero mess during removal of the original sliding glass patio doors. Mario is polite and moves with knowledge and expertise with each step from start to finish. Everyone at One Window at a time understands service, is responsive, and does quality work. Only having 2 sliding glass doors to remove and replace, and I was concerned it wouldnâ  t be a large enough job, however, no job is too small. I can already see and feel a huge difference in the quality of the door itself from noise reduction and keeping both heat and cold from outside in and inside out. Thank you to Bruce and Mario! 5 Star rating!"

Customers say: Terrific value

"We recently had an egress window installed and couldn’t be happier with the experience. The team was professional, efficient, and paid great attention to detail from start to finish. They kept the work area clean and made sure everything was done to a high standard. The window looks fantastic and has completely transformed the space. We’re so glad we chose them for this project and would highly recommend them to anyone looking for quality work and great service."

"We had DMD intall a bay window for us in the 80's and were so pleased with the results. Needing to place windows and doors, I was delighted to see they were still here. Again, Bill was most accommodating and and responded to questions in a timely manner. Chad, Alex and Kevin came to demo and replace 2 sliding glass doors and several windows. Their work ethic and teamwork was unbelievable. I HIGHLY recommend DMD for any work you may want done."

"Windows are good. Work was sloppy. Still finding shards of glass on the floor and the furniture a week after completion. Caulking looks like a third grader did it- including caulking the screen door to the frame. For this type of investment, they should act like professionals."

"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."

Glaziers FAQs, answered by experts

Glass fences are extremely strong. You can drop 10mm thick tempered glass on concrete and it wouldn't break. Considering that certain types of glass are bulletproof, glass has the capacity to be exceptionally durable and resistant to breaking. Certain types of glass, like laminated glass, are designed to not shatter at all, but rather break into giant pieces.

When glass shatters, larger shards quickly drop to the ground, but smaller particles can go on an airborne journey up to 15 feet from the point of impact. So check under furniture, along the edges of rugs, and in dark corners for glass fragments. When in doubt, vacuum the entire room a few times after thoroughly cleaning.

White vinegar, water, and baking soda create a natural cleaning solution that is highly effective against brown stains on the oven door. Mix one cup of baking soda, one-fourth cup of water, and one teaspoon of vinegar into a paste. Spread it evenly onto the oven glass and let it sit for 15 to 20 minutes. Then, scrape the mixture off with a plastic spatula. Wipe the glass with white vinegar to remove any remaining baking soda.

Glass walls are more expensive overall than their brick or drywall counterparts. However, if you need walls for a building with more than two or three stories, glass walls are the more budget-friendly option.

You should avoid multi-surface cleaners, bleach, and any cloth or scrubbing material that has a rough surface when cleaning mirrors. Multi-surface cleaners and bleach will get smudges and debris off of the glass, but they more often leave behind cleaner residue because they don’t evaporate like a glass cleaner or rubbing alcohol. Additionally, any abrasive material or even the scrubbing side of a sponge can scratch your glass or coatings on the glass, gradually making the mirror look hazy.
