 Granite State Pressure Washing, Pressure Washing, Hollis, NH

The BEST!!! We had Granite State Pressure Washing come out to do our house when we first moved in. It was covered in mold and slime and was disgusting. After they completed the steam clean/pressure washing, the house glowed. I was blown away at how excellent our house came out. We now have it done every other year. The price has stayed the same along with the quality. I would recommend them to anyone!!! This really is the best bang for your buck. Thanks again to the Granite State Pressure Washing Team!!!

The residents at Barretts Hill would like to thank you for a wonderful job! B., Hudson, NH

Thank you for a great job! Maurice Amherst, NH

My house was green (really yellow siding!) and the roof was full of mildew, mold and crap. He power washed the entire house AND treated the roof and the place is shining right down to my front stairs that were black....now back to a nice light rock color! I can't say enough about this guy and his work. The owner is Mark and he was the one that came and did the job...been in business 17 years and was early, a hard worker and so professional. There is a 5 year guarantee on the roof cleaning, too! There is a $50.00 coupon on his site. I would never use anyone else. Karen Nashua, NH

Hi Mark, here are some before & after pictures of the roof that you cleaned in case you wanted some examples to show to prospective customers. As I mentioned you did a great job and exceeded ALL expectations Brian Hollis, NH
