"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!"

"We have casement windows requiring lots of TLC. The windows are beautiful but the cranks, locks and latches frequently need servicing due to misuse and the ocean air and moisture. ABA Windows has rescued our windows many times with short notice. They are safety first, conscientious and really great with repair. Never any pressure to replace the windows. ABA values a quality product and is willing to go out of their way to find an elusive part and get the job completed properly. They also replace glass! Affordable, precise and efficient. As an added plus they are local!"

"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!"

Glass Block Windows FAQs, answered by experts

Glass block windows typically last for 15 to 30 years, which is slightly less than the 20- to 50-year lifespan of standard windows. You can extend their life by resealing them every few years. Professional installation is also key to ensuring the windows are placed correctly and will function properly for years to come. A professional installer will have the necessary skills, tools, and knowledge to install these features and can identify potential issues like damaged frames or cramped areas during a consultation.

DIY is possible for small projects, but professional installation ensures proper sealing, structural integrity, and a precise finish.

Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.

Yes, professionals can install decorative or colored glass block patterns for a unique look.

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.
