Joe Rosati installed a four door Anderson Slider in our den in October 2020. It was a big undertaking and it required new heavy duty headers and a great deal of ability and experience. My biggest concern with a contractor is reliability and temperament and of course talent. He is completely and totally reliable, and is an absolute pleasure to deal with. He will go out of his way to make you happy and his work is incredible. His prices are fair and reasonable, he tells you what extras might occur if some unexpected circumstances arise and I would highly recommend him to do any type of construction or large scale renovation. He is a perfectionist and has an eye for fine detail. I consider myself fortunate to have found him and for having him to do the job. I would give him ten stars in that was an option.
