"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

"I thought they were very positive. I liked them. I haven't had any window work done. I don't remember how much the cost was. They didn't do any work, so this is on their approach and bidding. I didn't use them because I haven't had the windows done. They did follow up and call me a couple of times, and I really appreciated that. I haven't decided and I am leaning in the direction of the contractor who came out to look at it; I just didn't get a bid from him. I would rather contact them if I decide to go with them."

"We remodeled our kitchen, which I?ve heard can be a nightmare! Not for us! I have to say that all the crafts people from the demo guys, plumbing, drywall, patch, and paint, carpenters were all top notch, professional, courteous, and polite.? They did not disturb my neighbors, they arrived each morning when they said they would, and cleaned up every day.?? Highly recommend!"

"They are very polite.  They keep moving and get the job done.  They go above and beyond.  I thought they would be done with the windows by 4 pm, they actually were done at 6 pm, with adding little things on, and they didn’t charge me extra.  They do a good job of hanging Christmas lights and usually have pretty good suggestions, based on what I want of where the lights should go and so forth."

Glass Block Windows FAQs, answered by experts

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

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. 

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

Heavy glass tends to be more expensive than thin glass because it is stronger and more durable. In most cases, ¼-inch-thick glass is ideal for mirrors, and ⅛-inch-thick glass is ideal for residential windows. Heavier glass isn’t always necessary, and can be more challenging to hang or install. Work with a local window installation pro for replacement or new construction windows.

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.
