I would highly recommend Great Falls Development Co. to anyone looking to have a stamped concrete patio installed. The employees we dealt with within this company were all extremely professional and personable. The work they did was superb, the time it took was exactly as stated it would be and the cost was reasonable for the services provided. The company normally will not take clients who don't meet a minimum square footage for the patio (which ours was less than b/c it was off a townhouse) but since we came from a referal he was willing to make an exception and do the work for us. We have been so happy with our patio and 18 months later have had no problems.
