"After dealing with frequent roof repairs, we finally decided on a complete replacement for our Livermore home. Avi kept us informed every step of the way, and the finished roof exceeded our expectations. It's made a noticeable difference during hot summer days."

"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 come in various patterns and styles that offer privacy and unique aesthetics. Frosted or textured glass diffuses light and enhances privacy. Wave-pattern glass blocks imitate ocean waves with flowing lines. Ice-glass blocks resemble cracked ice. Fluted glass blocks feature parallel vertical grooves, adding texture and depth. Clear glass blocks, similar to glass Coke bottles, offer transparency with some distortion and may have smooth surfaces or subtle textures, adding visual interest.

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.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

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.

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.

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts
