"Stay away from HomePros General Contracting, which also does business as HomeStory Doors. I paid in full for 2 sets of closet doors in August and was told the doors would arrive in 6-8 weeks. It has been more than 10 weeks and I don’t have new closet doors. I have called dozens of times and sent several emails but haven’t received a response."

All of your masonry needs quality is first and foremost. I have been in the masonry field for over 15 years. When I was taught the trade my teachers motto was do every job as if it were your own home, and I live by that and take pride in every job I do because I love what I do.

"RUN!!! Do not use this service. This guy broke up my cement to my house, while doing another job, which was poorly done. He is refusing to pay for the cement that was good prior to his arrival. The retaining wall he called himself putting up was done very sloppy. He dies not return calls and consistently keeps lying. After seeing these reviews I see why. Do yourself a favor DO NOT USE THIS COMPANY!"

Glass Block questions, answered by experts

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.

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.

Pros

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing

  • Strong and secure

Cons

  • Costly to install

  • Challenging installation

  • Challenging repair

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. 

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.

Glass blocks are much thicker than glass panes in traditional windows and serve as better insulators. The overall glass block window is sealed against drafts that allow warm or cool air to escape, saving on energy costs. Since this type of window is sealed airtight into your home, you don’t have to worry about air leaks and drafts as often as traditional windows that open and close. When installing glass block windows, look for options that are Energy Star rated, proving their energy efficiency.
