"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

"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."

"I dealt with Darin for these projects. The one thing that stood out was the professionalism. Right from the start we knew the dates of the projects and were kept in constant communication. The work was done well and everyone was very respectful. These weren't huge projects but we were still treated as if we we're an important customer. I would highly recommend them and use them again!

Glass Block questions, answered by experts

Glass block windows come in various patterns and styles that offer privacy and unique aesthetics. Frosted or textured glass diffuses light and enhances privacy. Wave-pattern glass blocks imitate ocean waves with flowing lines. Ice-glass blocks resemble cracked ice. Fluted glass blocks feature parallel vertical grooves, adding texture and depth. Clear glass blocks, similar to glass Coke bottles, offer transparency with some distortion and may have smooth surfaces or subtle textures, adding visual interest.

Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.

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.

DIY is possible for small projects, but professional installation ensures proper sealing, structural integrity, and a precise finish.

Glass walls are more expensive overall than their brick or drywall counterparts. However, if you need walls for a building with more than two or three stories, glass walls are the more budget-friendly option.
