Get matched with top glaziers in Mastic, NY

"This was the third time we used Therno Seal and again we could not be happier. The two prior times were to replace the windows in the house. The windows are awesome and Aaron will work within your budget. This business is family owned so there aren’t tons of calls and a pressure presentations to buy the top of the line product. Well this time we needed a new roof. I amazed how good this roof looks. It turned out that we needed teardown of the whole roof but that was ok because everything was laid out before hand of what can happen. .Aaron explains everything up front and is always available if you have any questions. When it came to work on the roof the head guy was Bob. He doesn’t just drop off a crew and leave. He stayed the entire time making sure the job was done the right way. The job was done in two days. You can tell Aaron and Bob take great pride in there products. If you want quality and good service give them a call. Working with them is like working with friends. Thanks again guys!!
