Took several calls but when Gene received my query he was attentive, reviewed photos & dimensions, and helped me conclude glass block would not be the best way for me to pass a pipe from an outside oil tank to my furnance.

The men did a wonderful job. It was completed in approx 1 1/2 hours. They laid down tarps and cleaned up thoroughly when finished. The windows look great and I now have ventilation where there previously was none.

Keystone Glass Block Company has to be the most professional contractor I've had to deal with in the past 10 years. Had to replace 2 windows, 1 in the utility room, and the other in the downstairs bathroom. Both windows were original to the house (62 years old) and were replaced with glass block. The price was reasonable and the work done was outstanding. The workers showed-up at the appointed tim...

The service and results are exceptional. They replaced the block with cement from cinder block to cinderblock without disrupting our basement some of which was finished. They were the best I could have imagined. Gene the owner was on top of the entire process and the results were perfect. There is no longer a leak. It was perfect in all ways. They are the best. Hire them. In fact, our water proofi...

Description of Work
Our glass block from when the house was built was leaking. The original glass block was installed over a wood base. It was not done in the best way because rage original builder did it in a less expensive and effective way. Gene’s team came out and reviewed the problem to replace the glass block in three windows.

I did not hire Gene because we had a fairly complex issue involving leaking through a louvered vent in and existing glass block window. Importantly Gene took the time to explain some potential options, including DYI, over the phone. He was prompt getting back, thorough, and creative with his suggestions.

Great! Gene was very professional. Polite. Pricing was very reasonable, also, got a discount for going through Angie's List. His employee's were on time, very competent, friendly, proficient and left the work site spotless. The windows look beautiful. I've received many compliments on the new windows. I am very satisfied with Keystone Glass.

I just bought my house and found out that the two basement windows were rotten and termite eaten. I had them replaced with glass block, they look really nice and the installers did a nice job.

Windows look amazing, completely satisfied and would hire again in a he...
