San Diego Pool Tile Cleaning was awesome and the price was fair.  Our pool tile had terrible calcium lines that I had tried to scrub with pumice and spent at least $50 in chemicals to try to clean to no avail. Roark returned my call promptly, had me text him some photos and gave me an estimate.  His estimate was the price I paid.  Pretty easy. They arrived on time and started work.  Everyone was very cordial and considerate and I think they were here about 4 hours or so.  The tile looks brand new now and they cleaned up the deck before they left. I would recommend them without reservation!
