"Curtis and Leslie were so very nice. They did a great job soft washing our home. They were prompt, thorough, and professional.
Our house looks great and we will definitely not only use them again, but recommend them to friends and family!"  Laura T.

"We were super please with Thorowash. They were great to work with and did a wonderful job with our house cleaning! Highly recommend and will be using Thorowash again."  Shawn S.


"Curtis and Leslie couldn’t have been better. Their quality approach was top-notch. Leslie took before and after photos. She even took photos of the placement of items on the front porch and patio. Just so they put the items moved back where they belong! Their equipment worked flawlessly. The attention to detail was tremendous. The rate of work performance was spot on. After the job was completed we did a walk around to check the work. I was amazed at the level of cleanliness of everything! I would readily recommend Thorowash LLC. There is real value in their services!"  Tim W. 

"Absolutely love the work they do!! Used in the past, used yesterday and will use and recommend in the future!" LeighAnn W.

"We received great reviews from our neighbors who used Thorowash and so we gave them a call. They did a great job with our house. They were very considerate. We have several bird nests including one on our front door wreath. The nests were covered to keep them safe.
Our gutters were clogged. Thorowash disassembled them and flushed them out completely. Nice job! Thanks!"
