"When we picked up the glass yesterday evening, we noticed one of them was wrong size (the glass was less half size of our table). 
They came in today and measured the table again.
Mistakes happens.   They acknowledge it and move on remediating it.  Great company

"Desmond installed glass block in the basement window well to replace a leaking casement window. He quickly returned my call for an estimate and gave me a quote upon inspection. He installed the glass block perfectly along with waterproofing and even did an extra coating of mortar on the outside sill so that water would slope away from the window. The work was done expertly. I would highly recommend Desmond - he is very nice person, knowledgeable and performs stellar work."

"Fabiano was a pleasure to work with. He was punctual when showing up to provide an estimate and to the project itself. He gave me accurate time lines and updates in real time when fixing my deck. After comparing 4 other contractors to replace my deck, Fabiano gave the best quote with no surprises and the estimate was spot on! I would absolutely recommend Fabiano for your next project"

"The work took about a week to complete, although Dan used a plumber who installed the shower hardware and fixtures and the floor and glass for the shower. That took a few weeks longer to install because the glass needed to be measured and specially ordered. But it was worth the wait!"

"After having a positive experience with RJ Little LLC last month, I interacted through email to get a recommendation on a whole house surge protector to replace the old out of warranty unit I have. Received quote through email and scheduled installation. Installer showed ontime and was very professional. He cleaned up when done and showed me what he had done along with providing me with the warranty information for the surge protector. I was very satisfied with the job."

Glass Block questions, answered by experts

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

Their thickness depends on application, but most glass walls are typically 3/8 to 3/4 of an inch thick. Although it’s not as common, single panes of glass can also be 1 inch thick.

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. 

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

Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing
