Pressure washing / house washing

We take pride in our quality of workmanship and customer service because a one time customer should be a lifetime customer!

  • I would recommend this business

Mark came to pressure wash our home today. We have had 9 years of build up on a yellow house, we did what we could but could never reach the top of the house. I can not say enough nice things about GSPW, Mark was very friendly and professional. He was quick, and our home looks brand new. I had other quotes when I first started looking around and he was BY FAR, the cheapest but he gave what other companies did not....a 2 year guarantee on his work! Really great experience and I could not be happier with the outcome!

Hard to believe that a house and surrounding hardscape can sparkle but that is the only word to describe my property after these guys are done with it. I confess, I have a small power washer of my own BUT it takes me forever and the results are just not as good as what Granite State can achieve. You will absolutely NOT be sorry when you hire this company. Prompt to arrive, returns calls quickly, friendly and do an unbelievable job. I'll be back next year - my 9th in a row!!

Terrific service....I have seen other fly by night powerwash contractors who buy their gear from Home Depot and run around tearing up everyone's siding.....Granite State is the real deal....we had some serious staining due to rainfall on side of house....GS took care of everything including some of the famous spider droppings on our front "white" garage doors.....just an excellent service.

Customer Testimonials

Can’t say enough great things about this company!
Mark did a fantastic job on our house.
We highly recommend him, very professional and friendly!


Mark was fantastic. He was great. Highly recommend. My house looks brand new. Told me if I had any problems or spots coming back to call him and he would come out to fix it. A+++. Very professional and thorough.


Excellent Experience!
Mark returned my phone call and we scheduled the appointment.
He came early in the morning as scheduled, and he did an absolutely amazing job.
The house looks beautiful now and I highly recommend him!


We were the second house in a brand new neighborhood it was still a dirt road when we moved in. This is our third year in the home. We have had construction trucks going by the house for 2.5 years, all the construction is finally done. We had never power washed before, the house was a mess. He did an overview with me prior to starting the job. He set the proper expectation. Giving me details about the process and what to expect when he left. Very nice, very professional. But, most importantly he did an excellent job.


Great experience. Easy to work with. House looks great! Would recommend and will use again.

From Our Website

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


Protect your investment! Your building and property are major investments in your business and should always be maintained properly. Your property's appearance can impress or likewise disappoint your customers. Buildings, Floors, Factory Interiors, Decks and Fences all collect debris and do weather over time. Professional power washing with the correct equipment and proper application methods is the most effective method to remove dirt, mold, mildew, gum, paint and other foreign materials that collect on surfaces.


Granite State Pressure Washing provides top quality truck and heavy equipment washing to vehicle fleets of all sizes. Our prices are competitive with industry standards using high quality professional equipment and chemicals. Wash water runoff is collected when required.
