This is a very professional company (business since 1957) that was easy to deal with and finished the work in 2 hours. After getting a few quotes I found that for the cost (which included installing a whirly fan on the roof) these guys were very competitive as well as informative, I found there were a few contractors who wanted to just blow in fiberglass over existing fiberglass with no mention or knowledge of proper preparation or use of cellulose. I would definitely recommend these guys based on their professionalism, quality of products and services.
