"George did an excellent job power washing my patio. I spilled oil on it and he cleaned it and now it looks like new concrete. He also power washed the patio ceiling and it is so fresh and clean. I highly recommend George for your project. Job well done!! KH"

"The representative from J and P came to my home when he said he would and got right to work. He had a great system and he worked the system until the job was complete. I was so happy to have clean windows, screens, and window sills. He was very neat and did not make a mess. When he left, I did not have to do a thing and I had clean bright shining windows."

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again."
