"All around, Arrow Masonry was outstanding. Mike visited our 3-flat building several times over the last few years to diagnose and advise on different problems, saving us thousands in unnecessary repairs. I sincerely wish all service providers and contractors operated the way Mike's operation does. This is a well-oiled machine with a commitment to quality and a pride for getting the details right. I highly recommend Mike and Arrow Masonry for any brick, block, and cement sealing and repair work. We were in year 8 of our split-face block's 10-year sealant life expectancy. In preparation for a re-seal, a major building expense, we did some preliminary shopping and received 4 quotes last year. Mike's quote wasn't the cheapest and it wasn't the most expensive. However, his command of masonry and ability to call out the details was impressive. He and his office (shout out to Patti!) were highly responsive as well. Our Association felt the most confidence in Mike's quote and decided that when the time came, we would go with Arrow Masonry. This year, the units in our building experienced 3 leaks above 3 different windows within 120 days. Time to accelerate the sealing job! We were able to get Mike and his crew scheduled to come out within 2 weeks. The crew showed up, on time, at 7 AM sharp and worked through 5 PM each day. It took a total of 4 days to get the job done. After each day, they cleaned up the entire site as if they were never there. This was greatly appreciated. Steve, the foreman, and the rest of the crew were incredibly professional, knowledgeable, and addressed a lot of extra details that we did not even ask the team to address. They repaired our front steps, unprompted, and did a high quality overhaul of the flashing on our rear balconies to help prevent runoff down the exterior block below each deck. I did a final review the day after the job, loaded up a photo album of small adjustments that had to be made, shared with Mike, and he had the crew out in 24 hours, a Saturday morning, to wrap up all the final details. They really knocked it out of the park! Our Association could not be more satisfied with the job and the experience. We will happily use them again when the need arises."

Glass Block questions, 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.

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. 

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

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.
