"John at Cornerstone Masonry did an outstanding job of replacing missing bricks and tuck pointing a very large area on my Polk Blvd all brick home. The work was top notch and makes this century old two story look like new. The quality of the work was excellent with attention to the smallest details. Punctuality and communication were excellent. The job was done on time and for the quoted amount. I am very satisfied with the finished product and I have hired them for another project."

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

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.
