The whole team was great about keeping the workspace tidy, which we appreciated. Now, we have a bathroom that feels luxurious and welcoming. Highly satisfied with their work!"

"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."

"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!"

"GoodFellas did the master and guest bathroom in our home. My wife and I are expecting a child in Nov and wanted to get as much work done on the house before the baby was born. GoodFellas was able to finish the work in a timely matter and exceed expectations. Even though the company is handling multiple jobs at a time, they are able to make us feel like were the only ones, giving us complete attention when needed. They aren't cutting corners so it is well priced for the quality you get. Our project manager was there when we needed him including picking out the tile, glass and marble.

Glass Block FAQs, answered by experts

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

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.

Yes, many professionals provide custom-cut glass replacements for enclosures that require precise sizing.

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 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.
