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.)

Glass block adds light : This article talks about the benefits concrete over hot glue.

If you really want to find out what a company will do for you, and what they might be hoping that you don't ask about, check out our article:  Mortar, Hot-Melt or Silicone.

More Light

Our mortar bonds to your concrete basement walls so we can remove the framing surrounding your window. Less space wasted on framing means more light for you.

No Leaks

FEMA recommends glass blocking basement windows in areas prone to flooding -- a well installed glass block window acts as part of your wall, avoiding leaks between the wood frame and the window.

More Secure

Intruders will not be able to easily break through a properly manufactured glass block window. We never use silicone or "hot melt" sealant shortcuts; your blocks are mortared together with cement. Our no-rust banding gives our glass block windows up to 800 pounds of additional vertical strength.

Venting available

We offer window vent and dryer vent options. Some municipalities require a window vent in bathrooms if you do not have a bathroom fan.

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.

Cracking

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.

Light

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.

Building Codes

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.

Dan S – Milwaukee, WI

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!
