"Kevin and his crew showed up up for us on a very last minute request. He was very helpful and willing to make it work when we were under a time crunch. We had called several companies hoping to get someone out, and he was one of the few who was willing to come out and actually perform the work, rather than just come for an estimate only. Furthermore, he was prompt in returning our initial phone call, and called us again before he planned to arrive at the house.
The crew was quick, efficient and I believe we were given a very fair price for the amount of windows- cleaned inside and out on a three story home.
Thanks to Kevin and his crew for making it work for us.
A company who caters to their clients is a real bonus these days, when so often it is the other way around.

"Martin and his crew completed ten very involved projects for us today. We are very pleased with the work as it was done in a very professional manner. Martin indicated they could complete the jobs in one day and they accomplished this. The jobs involved power washing, painting, repair of towel bar, grouting, fixing hinges on a door, repair of garage door frame and cleaning of spindles on the porch. We told Martin that we were very happy with the results and would call him in the future for other projects that might be needed. Richard Huckstadt 5/19/26."
