"After dealing with frequent roof repairs, we finally decided on a complete replacement for our Livermore home. Avi kept us informed every step of the way, and the finished roof exceeded our expectations. It's made a noticeable difference during hot summer days."

"Did a good job initially. Did not install small plugs that cover the screws holding the window to the frame. Failed to respond to come back and do it. Some cosmetic drawback to their good job. Weak customer services!"

"We remodeled our kitchen, which I?ve heard can be a nightmare! Not for us! I have to say that all the crafts people from the demo guys, plumbing, drywall, patch, and paint, carpenters were all top notch, professional, courteous, and polite.? They did not disturb my neighbors, they arrived each morning when they said they would, and cleaned up every day.?? Highly recommend!"

Glass Block FAQs, answered by experts

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

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.

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.

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

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.
