J. Doheny (a family owned business) came and gave us a free estimate on replacing our existing cracked basement windows with glassblocks. His estimate was about $50 less per window than the other contractors that we had talked to. We hired him for the replacement. The new windows were delivered (by his son) about a week after we ordered them and he came back a few days after the delivery to install them. They worked very quickly and cleaned everything up when they were done. The windows look great and offer the daylight with privacy and we opted for the vented kind so that we could get fresh air in the basement. They also use a waterproof mortar so there is no more seepage during snow melt or heavy rains. Very happy with the windows and the service. Would recommend.
