George Ohlson and his son, Carl Ohlson, are very genuine contractors. They did a room addition at my house in Lafyette, CA and finished it on schedule and in my budget. It was greatly appreciated that my house was kept very clean throughout the remodel process. I highly recommend Ohlson Constructuon Services.
