Dwayne did a fantastic job cleaning the gutters, windows and power washing entire duplex. He called me back promptly and quoted a fair price for the work. He showed up on time on the scheduled date. Work was completed and they did a great job being careful of a package that was delivered while they were cleaning as well as area surrounding house and work-area. Would recommend Mertz to anyone and look forward to contacting them again in the future!

I needed my windows cleaned on a certain day prior to storm windows being installed. Dwayne came out to give me an estimate and scheduled it on the day I needed it and came that day on time and did a good job. What could be better? I am 100% satisfied. Would you use him again...and probably should have my windows cleaned more often

Called after storm on Sunday and realized gutter on back patio was clogged. They answered promptly and said he would be there by noon on Monday. Was on time cleaned out gutter and checked the others including my neighbors. Would use again and recommend
