"Michael loves glass and finds beauty in its many incarnations. He created an exquisite front door piece for my house 9 years ago. All that door has done is look gorgeous. Haven't had a lick of trouble with it. And, Michael repaired an old glass tile for me too -- at cost even -- because he appreciated it as much as I do. The company also made glass inserts for cabinet doors which are lovely - more banal than the dramatic entrance but equally trouble free. I would hire them again in a heart beat."

"I had the pleasure of working with the owner of the company Josh. What a wonderful job was done to my shower. I did not find a better price in all of Los Angeles and the areas in proximity. I felt heard and guided through the whole service, we were on the same page and I got the shower I wanted with the space I had. Highly recommend!"

"They did a great job. We were really impressed with how responsive they were - they came and gave us an estimate while the shower was still being built and installed the glass as soon as it was possible to do so - so there was no delay at all. Very happy with the end result."

"My large and very elaborate leaded-glass door was recently broken by impact from the outside. This happened at a place in the design that contained four different patterns of clear glass. Sergio at Divine Stained Glass removed the glass panel, replaced it temporarily with a pressed wood panel, and set about to track down all four designs of the glass needed. That was not an easy chore. He persevered until he found them all, and not only replaced the broken pieces but reinforced all the seems in the entire door, of which there are many. I couldn't not be happier with the work and the personal consideration I received from them. They are truly artists and amazing craftsmen."

Glass Block FAQs, answered by experts

Glass block windows typically last for 15 to 30 years, which is slightly less than the 20- to 50-year lifespan of standard windows. You can extend their life by resealing them every few years. Professional installation is also key to ensuring the windows are placed correctly and will function properly for years to come. A professional installer will have the necessary skills, tools, and knowledge to install these features and can identify potential issues like damaged frames or cramped areas during a consultation.

Most installations take 1-3 days, depending on the number of blocks and customization requirements.

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.

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. 

Glass block mortar is the best choice for glass block window units. It is specifically formulated for glass block window installation. Glass block mortar is usually a mixture of Portland cement, sand, and special chemicals. It is a white mortar that is applicable inside and outside your home. Do not use regular tile mortar because it may not have the binding strength and flexibility required for glass block windows.
