We were very pleased with the power washing services we received. They did an excellent job cleaning the sides of our house, windows, and concrete patio. The team was professional, hardworking, and completed everything exactly as promised. The concrete work was spectacular—it looked like new when they were finished! We were extremely satisfied with the quality of their work and would definitely hire this company again. Highly recommend!

We needed our back patio and parts of the house power washed and found McMorris Power Washing through social media. The response time to the initial inquiry was quick and we received an on-site estimate. The price was good and the company’s availability met our scheduling needs. On the day of our appointment, Andrew was professional and pleasant. He delivered exactly what we needed!

These guys did an amazing job for my house in Hicksville. Very professional and made sure to ask questions so everything that needed to be done would be taken of. Made sure I was happy with the outcome before leaving as well. Would recommend to everyone, and will be using them again whenever I need the service.

They cleaned my fence, pavers, and siding as requested. Cleaning job was fine but they left my patio furniture on my lawn after they were done. Reached out to let them know, and they told me someone would be here later that same day or the next to put things back. Needless to say, that never happened. Could’ve had a reliable customer for years. Will look elsewhere next year.

We decided to give McMorris Power Washing a chance after they were going door-to-door in our neighborhood. They came into our backyard, looked at our pavers, and told us they weren’t that dirty and didn’t need power washing—just polymeric sand sealing. Trusting their expertise, we agreed. They came the next day and sealed the pavers, but the result was extremely disappointing. The application was messy and uneven, with sand smeared across the surface and clumped in the joints. It looks worse than before they started, and we now have an unsightly finish all around our pool area. To make matters worse, they admitted to brushing some of the excess sand directly into our pool. This is incredibly unprofessional and careless, and now we’re dealing with sand in the water on top of the poor sealing job. When we expressed our concerns, they offered to take $100 off for labor—but wouldn’t come down any lower. That feels completely unreasonable given the poor quality of the work and the unnecessary mess they created. We’re very disappointed and would not recommend this company. What was supposed to be a simple improvement ended up being a frustrating and costly experience.
