Cleveland-born, family-run — we’ve been building with glass block since 2004
We’re Glass Block Headquarters, a family-owned crew based at 2007 Progress Ave, Columbus, OH 43207, United States. Since 2004, this has been our lane: glass block done right, from basements to bathrooms and everything between. We keep it local on purpose—serving Northeast Ohio means we know the homes, the weather, and the little quirks of every neighborhood.
Our reputation was earned the slow way: one clean install at a time. You’ll see our wrapped trucks around town, our team in the same uniforms, and the same friendly faces on repeat jobs. No call centers. No mystery subs. Just our in-house installers who take pride in tight joints, straight lines, and tidy worksites. That approach has led to an A+ vibe across reviews and a whole lot of word-of-mouth we’re grateful for.
What we make & how we make it: windows, walls, vents, egress—built to last
We design and install glass block windows for basements, baths, garages, and utility spaces, plus egress solutions where code and safety call for them. Need a shower wall, a bar face, or a light-splitting partition? We craft those too. We also handle repairs, tuckpointing, and ventilation add-ons—fresh-air vents or dryer vents integrated cleanly into your block so you keep airflow without losing security or privacy.
Materials matter. We build with Seves Glass Block for clarity, strength, and consistent sizing. For the seams, we use GE silicone—tough, resilient, and weather-smart—so your panels resist moisture, drafts, and seasonal movement. It’s the kind of spec you don’t notice on day one, but you’ll appreciate in year ten when everything still looks tight and feels solid.
Every project starts with careful measuring and a straight-talk estimate. We walk you through styles, vent options, privacy patterns, and egress requirements, then schedule a crew that shows up on time and protects your space. Install day is efficient: remove, prep, set, level, seal, and clean. You end up with brighter rooms, better security, and a bump in curb appeal—without babysitting the job.
Our promise: in-house crews, lifetime warranty, and real reviews to back it up
We don’t outsource installs. Keeping the work in-house means consistent craftsmanship and accountability from the first call to the final wipe-down. If something needs attention, you call us directly at (216) 941-5470 and the same people who built it make it right. That’s also why we offer a lifetime, transferable warranty on our glass block installations—protection that actually follows the home.
Service should feel simple. We book Monday through Friday (8:00–4:00), confirm ahead of time, and leave the site cleaner than we found it. Most jobs wrap in a single visit, and we haul away debris so you’re not stuck with a pile of old glass and mortar. It’s professional, but it’s also neighborly—because we live here too.
Don’t just take our word for it. We’ve collected a stack of verified reviews across Cleveland and Columbus that highlight the same themes: careful measuring, crisp workmanship, clear communication, and crews who respect the home. That feedback fuels us. If you want glass block that looks sharp, strengthens security, and brightens your space, we’re ready to build it—right here in Northeast Ohio.
