"We could not be happier with our new bathroom, thanks to McCormick! Khaled was knowledgeable and really took the time to understand our style preferences. 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!"

"They did a great job. We were really impressed with how responsive they were - they came and gave us an estimate while the shower was still being built and installed the glass as soon as it was possible to do so - so there was no delay at all. Very happy with the end result."

"Chris did a great job replacing the sliding glass door and window installation. A lot of attention was given to the details and workmanship. The Milgard product is superior for the price. We would highly recommend this company."

We are happy with the whole process of initiating the project, arranging the service and the service itself. Very fast response from the office clerk and the owner. The two year warranty provided by the company gave us a piece of mind. The job was done in less than the week. If the nice painting sustains over the years to come as promised by the owner, we could certainly hire them back for other painting and roof needs.

"He came for the estimate last week and beat the previous estimates we received and went through the measurements with us for the height and width of the glass to ensure it would meet our expectations. He did not have samples of the glass but he had pictures which sufficed for us. We chose a plain glass as opposed to a frost or reeded because we figure it will stand the test of time better. He talked with us about the color of the clamps and helped us decide. Today he arrived a little over an hour late to do the install due to traffic, but once here it literally took like half an hour for the complete installation, so he more than made up for it. It looks amazing, just what we wanted, he was quick, and the glass is a high quality thick glass. I would certainly recommend his services."

"Steve and his team removed a load bearing wall, installed new cabinets, ran new electrical outlets in our kitchen, slab cut new electrical to a new island, and installed new flooring throughout the house. This was a bi project for our family, and I can’t say enough good things about Steve’s responsiveness. We had a number of contractors bid on our job, and Steve was the best by far when it came to talking us through the process. He was excellent when it came to changes, and recommended suppliers that fit our budget. He has an eye for quality, and if something isn’t done right he makes sure it’s fixed. Great company, great owner, great workers!@"

Glass Block FAQs, answered by experts

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 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.

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. 

You can still see vaguely into some types of glass block windows at night. Although there won’t be clear definitions, passersby may still see shapes, shadows, and movement through the glass. If you want complete privacy, consider installing diamond glass block windows rather than the typical clear or wavy glass blocks.

Most installations take 1-3 days, depending on the number of blocks and customization requirements.
