Glass block windows can be a great choice for basement or bathroom windows. Ours offer strength and security at an affordable price.
We use mortar on all of our glass block windows as well as a non-rusting poly-banding process to give our glass block windows strength. We use mortar not only on the sides, but between the blocks as well.
We offer both vented (pictured to the left) or non-vented.
Because there are many fad, or dated styles, we stick with the classic designs of either wave or ice (privacy) glass block.
Most customers choose the traditional wave pattern for basements and the ice pattern for bathrooms, but you can choose either block for your needs. If you are completing a project that was started with diamond, we can accommodate your needs, but we recommend against starting projects with dated designs. (Just like nobody would want to be caught dead with a mullet or a leisure suit these days.)

The Advantages of Mortar over Silicone
Strength & Security
Mortar is the strongest material on the market to put together a glass block window with. If someone attempts to kick in a mortared glass block window they will hurt themselves and fail break in.
Kick a silicone glass block window and chances are that it will buckle.
Mortar holds each block in place making it so they do not bang into each other and chip or flake off at the edges. The mortar becomes part of your house because our windows are mortared directly to the bricks or block in your basement.
"Hot Melt" or silicone blocks are right next to each other making it so that even natural seasonal settling and shifting in some houses can cause blocks to chip or flake off.
We remove the wood (also known as buck) frame from around the window and install directly to the masonry walls of your basement. The mortar, necessary for structural integrity, is only about 1/4 of an inch between each block.
A hot melt or silicone window gives the same amount of light. Although they are often advertised as giving you more light, the installation process of these windows requires that the installer use more mortar on the sides in order to make up for the space they are not using mortar for between the blocks.
Price vs Durability
Mortar remains an affordable material for creating glass block windows. While it is more labor intensive, the price difference is negligible and the product will last a lifetime.
One person can mass produce up to 30 siliconed or "hot melt" glass block windows in about an hour which makes it so you can produce these low quality windows for less. House flippers focused on a temporary or quick-fix may prefer cheap windows, but we find most homeowners are looking for something that will last longer than just a few years.
Mold & Mildew
With mortar filling all of the voids between the blocks, there is no danger of mildew between the blocks.
Voids between the glass are the perfect breeding places for black mold and mildew, especially once the silicone or glue starts to peel away or break down. Moisture then gets between the blocks.
Mortared glass block windows are approved for all communities.
Silicone or "hot melt" is not legal in all communities. Check your local building codes before installing one of these windows or allowing a company to install one.
I had serious water issues due to the sunken window wells and 90 year old windows. Jim did a great job! His workers were pleasant and efficient. This was far more than dropping in some windows. They creatively fit around wiring and vents and masterfully poured extensions to the concrete wells. A++ work!Read Full Testimonial >
Energy Masters did a fantastic job! They were very timely and efficient. The work was top quality and throughout the entire process we felt that we were dealing with honest, hard-working people. Anyone need any work done, these are the guys to call!Read Full Testimonial >

I get this question often, and for good reason — how much privacy will my glass block give me? The answer is “it depends”. Classic designs such as wave (popular for basements) offer some privacy, but the closer you get to it, the more anyone lurking outside your home will be able to see. If…
