All reviews for GRANTO GLASS BLOCK

Highly recommend Granto Glass Block. He came out the same day I called to give me a quote. Angie was wonderful to deal with in the office. The day of installation they showed up on time, got to work and replaced 4 windows, they took my old windows and cleaned up any mess they may have made in the process. It was a pleasure working with Granto Glass Block, they made everything easy from start to finish!

This was hands down the best business I have ever done with anyone. Gave me an estimate within an hour, were able to come do the job 2 days later. Had 7 glass block windows installed in one hour. Worth every penny.

Granto's did a GREAT job on our glass block windows. Gerry's crew was fantastic. They did an awesome job. They were prompt, courteous and the fit and finish on our new block windows is excellent. That's why we're repeat customers. Look no further - call Granto's.
Thank You Gerry! Joe Roscetti NF,NY

They did an awesome job installing new bedroom windows, basement glass block windows, and front door. I would highly recommend them if you are looking for installation of windows, doors, or other work.

Very pleased with results and they were quite efficient, whole job finished in an hour!c

Gerry Granto and his team were here this morning to replace 10 basement windows with glass block. They arrived on time, got right to work and were finished within a couple hours. Very friendly and professional. Gerry will return in 3-7 days to spray sealant around the windows. Very happy with the job. They even cleaned out my 4 window wells and brought my empty garbage tote up from the curb. The windows look great and my basement feels more secure. Thank you!

I highly recommend this company to anyone

Had them out to install a glass block window for a shower, could not be more pleased with their service. Whole process was very quick and easy!

Granto Glassblock!! These guys came in a team of 4 at 945am and finished 7 windows by 1145am!! They look amazing! They cleaned up everything! They took my old windows! Very professional from first contact to end of job. Mind you I contacted them YESTERDAY and they found a slot for me today. Extremely reasonable price! I HIGHLY recommend these guys for your glassblock windows and I know me and my family will never use anyone else. THANK YOU GRANTO GLASSBLOCK!

Repeat Customer! First, glass block for basement windows. Love them!
Second, replaced picture window with double hung windows. SUPERB!
No need to look any further. They offer quality, craftsmanship with value thrown in for fun! Will have them back again soon for more windows!

Very happy with my bathroom window install. I first had Buffalo Glass Block take a look at my window that is in my shower and they said they cant replace it and do all the trim work to seal the window as all they do is glass block. I then found Gerald Granto online and he was able to do exactly what I wanted. He showed up right when he said he would and completed the work in just under 2 hours. I had a window removed and replaced with glass block and he used never rot trim on the inside shower and caulked everything. I would definitely recommend Granto Construction for any glass block work.

I was pleased with their work
Made my basement so much brighter and safer. They were here on time and did a wonderful job. Kristen is great to work with. Thank you for a job well done

Just had a new bathroom window put in. He did a meticulous job, and was finished in 40 min.. My only regret is not getting it done sooner. THANK YOU GRANTO GLASS BLOCK!

Guys did a great job replacing a basement window on our house. They were polite, professional and did a great job cleaning up. Highly recommend!

Called for an estimate, the owner was polite and professional. Received a very reasonable estimate within the hour. The appointment was scheduled and the crew arrived on time. They were very professional and courteous, also cleaned up after themselves. Could not be more satisfied with the service. Highly recommend

Gerry (and Kristen) and his team are amazing! The service from start to finish was superior. Very communicative, kept me in the loop on when delivery of my windows would come in along with the install date. Very fair pricing as well. Gerry knew I was getting black on black windows later this spring and he went above and beyond to ensure my hopper window matched the rest of the house. Very appreciative! If you need glass block windows dont even think twice, go with Granto.

Excellent transaction from the beginning estimate through final completion of the project, everything went smooth. Will definitely be using again

Great people to work with, reasonable prices, efficient. They removed old windows and installed the glass block ones in under an hour.

Small job, but treated like it was a large one! Great communication from start to finish, The workers arrived 20 mins early, left the area cleaner than when they started. Very friendly staff. I would highly recommend, and use again! Thanks folks!!!

Just wanted to give a HUGE shoutout to Granto Glass Block for the incredible job they did on our basement! We had them install one egress window and six oversized glass block windows, and the entire process was smooth and stress-free.

From the start, they were super responsive and even worked with us to meet a tight deadline before our move-in date — something we really appreciated during a hectic time. They got us scheduled quickly and made sure everything was completed right on time.

The crew was clean, fast, and extremely efficient. They showed up on time, were respectful of our home, and kept the work area spotless. You could tell they take pride in what they do, and the quality of work speaks for itself.

On top of all that, their pricing was very affordable, especially compared to other quotes we received. The new windows look amazing, bring in so much more light, and give us peace of mind with added safety and security.

If you’re thinking about adding an egress window or upgrading your basement with glass block, we highly recommend Granto Glass Block. Professional, reliable, and great to work with!
