"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: 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."

"I was selling my house at that time, the buyer, I showed him everything and let him be my eyes and he was happy about everything. There was one of those two low tiles that weren't leveled and he asked them to come back out and level them like concrete roof tiles and they came back out and fixed it, that was it, it was something minor."

Glaziers FAQs, answered by experts

There are a few reasons your mirrors might have smears on them after cleaning, but the two most likely are remaining cleaning product and minerals from hard water. If you used a commercial glass cleaner, consider spraying down the mirror with a 1-to-1 ratio of white vinegar and water after cleaning and then wiping it dry with a cotton cloth. If you suspect hard water is the issue, use a cotton ball soaked in rubbing alcohol to spot-clean the streaks, and then let the mirror air-dry.

You can still see vaguely into some types of glass block windows at night. Although there won’t be clear definitions, passersby may still see shapes, shadows, and movement through the glass. If you want complete privacy, consider installing diamond glass block windows rather than the typical clear or wavy glass blocks.

To tell if a window is single or double-pane, focus on the edge. Double-pane windows have two glass layers separated by a spacer, which you can usually see around the edges. For single-pane windows, it’s just one sheet of glass. Another easy trick: shine a light at the window—single-pane glass reflects once, while double-pane glass reflects twice. Lastly, if you feel both sides of the glass on a cold day, double-paned windows will feel warmer because of the insulating gap between the panes.

You should dust your mirrors once every one to two weeks as a part of your normal cleaning routine, and you should plan on cleaning with a glass cleaner or DIY cleaning solution once a month or so. This will help reduce the buildup of hygiene products like hair spray on the mirror, as well as oils and dirt from fingers. You can always spot-clean between regular cleanings if you notice your mirror getting dirty or smudged.

Glass has one of the longest lifespans of any fencing materials, lasting anywhere from 10 to 30 years on average. Just how long your glass fence lasts depends on several factors, including how well you maintain your fence, the climate, and the type of glass you use. 

If you live somewhere with severe weather like hail, tornadoes, or hurricanes, expect your glass to have a shorter lifespan. Pool glass is one of the thickest tempered glass materials and may last longer than other options—especially compared to laminated glass.
