What customers said about rooftop/skylight cleaning
We had a power wash and window cleaning inside and outside as well as the skylight. I am amazed at how good it looks!! Great job!
Carpenter Cleaning did a fantastic job for us! We called last minute to have our windows cleaned and patio and driveway power washed to put our house on the market and they came the next day. They were prompt, professional, friendly and fairly priced. We will for sure use them again!
I truly cannot recommend them highly enough. They were thorough, fastidious, polite and really good at what they do. I’ve already scheduled them for the next time!
Such a great team! Dylan and his wife really helped me out in a pinch and worked me in last minute! They did an outstanding job!! They really pay attention to detail, and were very professional and courteous. I would not hesitate to use them again. We are getting so many compliments on how clean our windows are!
We like the young man who comes and does our windows and gutters. He does a good job and Bob can stay down off the ladder.
Very professional and great people. We have used Petersburg Power Washing many times and they have always gone above and beyond. The employees and the owners were wonderful to work with. Will definitely use them again.
