This is the 3rd summer we have been in this house. And each year we have had our cement deck around the pool power washed. The previous two years has not been successful as each time there was much streaking and not a thorough job. So this year we called Aqua Wash. What a difference! It looks like a whole different deck. There was a small area that did not come clean and with just a mention Richard was back on site and got the job done. We will be calling Aqua Wash each spring to get the job done right! Thanks so much for your help.
