"I was looking to replace a custom 1920's front door wall sconce, made from leaded stained glass. Margaret and Sea of Glass was a terrific find! They meticulously restored the sconce and updated with beautiful new color of unique glass. Easy to work with and flexible. Recommend for any custom stained glass repair or project."

"The price was good. They're responsiveness was good because there was a minor issue. It was mainly cosmetic. There were plastic caps that goes in the hole of the window after they put the screws through. They failed to put that. I called them, they were supposed to follow-up and they didn't follow-up. They never called me back and they never responsive to take care of that, unless they came and maybe my kids had them do it. The work was incomplete. It's really a minor thing. They're so stupid not to finish the job and they were good otherwise. They didn't get bad ratings, and I don't think the owner even knows. I called them actually six months to three months ago. I told them to come and finish up the final finishing touch of the window, which is part of their job. They never called back. I asked them to even have their owner call me. They're not responsive. The work they did was good except for this last item. I hate to give them a bad mark. They didn't follow up and have a bad reception. I'm not happy with the work because it's not fair that I gave them the full price and they didn't do a full job. Actually the workers were good. They came, they were efficient and did the job. The final touch they didn't do."

"This is our second time using Goodfellas.? We remodeled an entire floor which included the master bath, master closet, second bedroom with new walk in closet, which was quite a complicated operation. Adam was very responsive and always available keeping us up to date daily on progress. When we ran into issues, he was quick to call and was a good problem solver. I will recommend them to my friends and work with them again."

"We are so happy with his work!  The shower is wonderful, tiles look great, and he even put in detail in the shower!  We also chose a hexagon 1 inch tile for the floor and he did a great job lining them up and grouting them evenly.  He was professional, cleaned up every day, listened to what we wanted as well as offering suggestions, and got the job done on-time and on-budget.  We will definitely call Dragan for our next project!

"Reza responded to my email inquiry and called me right away. He showed up at my house on time to give an estimate and take the deposit. He installed the mirror four days later. He charged a little bit more than the others but he's worth it IMHO."

Glass Block FAQs, answered by experts

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.

New glass costs anywhere from $3 to $100 per square foot. More specifically, tempered and insulated glass—a common option for sliding glass doors—costs between $10 and $14 per square foot.

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 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.

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.
