"Detail-Oriented & Fast — AG Glass is the Best! AG Glass did an outstanding job installing glass enclosures on two of my showers. When Jorge went to pick up the hardware I had chosen, he noticed it wouldn’t match my champagne bronze sink and shower fixtures. Instead of just installing it, he called me right away and worked with me to find the perfect match. That kind of attention to detail and customer care is rare, and he handled it without causing any delays. The price was very fair, they came out almost immediately, and the work was completed quickly without sacrificing quality. Everything looks beautiful, and I couldn’t be happier. I highly recommend AG Glass for their professionalism, speed, and top-notch craftsmanship."

Customers say: Quality work

"Raul did the most perfect, artistic repair of the stained glass window in the door of our entry way. I made the window 40 years ago, in great detail in a stained glass class that I took. It was my second window and very challenging with beautiful colored antique glass with designs of ribbons weaving through flowers. My son accidentally cracked a piece of glass many years ago. I was afraid to have someone attempt to fix it because I thought it would be impossible. Raul's work was magnificent!!! He was able to match the different glass pieces that had broken over time. I couldn't be happier, just wish I would have called him years ago. Raul has my very highest recommendation. We are super delighted with the results."

"Great! They arrived within the time they had given us, and were done in 30 minutes. Only complaint was that we found small pieces of glass on the bed and floor in the room where the window was located, in spite of their vacuuming afterward. But job looks good."

"The job was during the first half of March 2019 for a 35 year old, 28 two- and three-story townhouse unit complex in Pasadena, California/trendy Playhouse District. As the current and prior/numerous years condo association president, I have had many experiences with contractors, including roofing, painting, plumbing, landscaping, and Chris Coyle is by far the most competent, reasonable, reliable, cooperative, fair and most professional of all the contractors. I would most highly recommend his services. During the plus two-week installation, Chris as company boss was "on top of job" because actually he himself and his assistant were installing/"doing the heavy lifting" for all of the new windows. This clearly illustrates his commitment/pride in his craftsmanship. Also, he is very knowledgeable about the window product/Milgard because he thought it best for this job to actually remove most of the old window frames, not customary for a/this "retrofit" versus "replacement" window installation. He was willing to do the extra work at no additional cost in order that the new window frames were not wide/distracting but thinner/minimal/open/clean/more open/glass configuration to enhance the overall modernization of the complex. I "gambled" with this new look for improving the complex, and Chris made not only the complex look good but me as president as well. Every- one is thrilled by the windows results, even asking "why didn't 'we' do this earlier?' I and the other homeowners do not hesitate at all in recommending Christopher Coyle and his Alta Sierra Windows company to any other homeowner. Richard, president, Oak Knoll Village homeowner association. (Thanks Chris!)"

"Woke up one night to a shattering noise, which was one of the glass shower walls crashing to the floor.  Called several other businesses to replace the glass, but their initial estimates were well over the Silver Shower Door estimates.  And since we are considering a bathroom remodel, it really didn't matter too much about quality, as much as cost.  They came out to get the measurements, and ordered the piece of glass.  When the glass came in, there was a scratch in the glass, and they had to re-order.  I said the scratch was OK since we were going to remodel anyway, but they insisted of re-ordering.  So, a couple of days later, they came back with the new glass, which was an excellent piece of glass; didn't see any drop in quality from the existing glass.  Installation was done in a snap.  They also replaced a splash guard at the bottom of the shower door at no additional cost, and were willing to reverse the door hinges, which were originally installed backwards, but since the door was functional, we chose not to have the hinges reversed.  Good company.  Would definitely use then again.

Glass Block Windows FAQs, answered by experts

Glass block installation can be relatively expensive due to the range of material costs and the labor time to assemble this type of specialty window. The process proceeds slowly as the glass does not absorb moisture from mortar and silicone caulk takes longer to harden, leaving spacers to hold up the structure until the caulk or mortar begins to cure. Plus, if your current windows have structural issues or damage, you’ll need to repair them before beginning the project, increasing your bottom line. 

Heavy glass tends to be more expensive than thin glass because it is stronger and more durable. In most cases, ¼-inch-thick glass is ideal for mirrors, and ⅛-inch-thick glass is ideal for residential windows. Heavier glass isn’t always necessary, and can be more challenging to hang or install. Work with a local window installation pro for replacement or new construction windows.

Yes, professionals can install decorative or colored glass block patterns for a unique look.

Although glass block windows are made of multiple layers of thick glass, they can still break. If an individual block shatters, it can be removed and replaced, but this is a job for a window repair professional. The project is often complex and may require breaking the block further for removal. Do not attempt to handle it yourself, as the broken glass can be dangerously sharp. A professional will have the necessary tools and expertise to replace the broken glass block quickly and safely. Before hiring, confirm that the repair pro has experience with this specific type of window.

Options include tempered, laminated, and tinted glass for various needs.
