 Trustindex verifies that the original source of the review is Google. Keenwick sent Eric over this morning to power wash our house and he did an incredible job! He showed up within the VERY reasonable 30 minute window, he was polite, left no mess, and did not take nearly as long as I thought it would. 5 stars easy.

 Trustindex verifies that the original source of the review is Google. Always do a good job. They get the ugly black stuff off the decks and railings!  Do a good job on the windows, get it done quickly.  Always pleasant. Fair pricing.
