A lot of people on here have recommended Ed with Under Pressure Power Washing. I was going to ask the same question, i need to get someone out to do our house too. https://www.facebook.com/pg/UPPWNC/about/
Tarheel Pressure Washing did my house and driveway. Very good job and reasonable. Locally owned too. Just saw one of their adds on here not too long ago. Check it out.
They have a coupon in the Yay local flyer that came in my mailbox today. Up to $150.00 off. You are welcome to have it. Dirt doctors also have coupons. So depending on cost.
