"D&H Demolition quickly demoed the carpet from my living, dining , and steps to the second floor. Replaced with re- claimed hardwood flooring which resulted in a significant cost savings for me. Replaced the flooring and steps with a satin finish that so beautiful that I keep getting comments. Work was timely completed and professionally done. I would definitely use their services again.
