Punctuality: A little late showing up (2:45 for 1PM). Cost: How big was my deck (only 200 sq ft covered by Angie's List deal)? Well, they didn't have a tape measure! First they said they were going to go to Lowe's to buy one, then instead asked if any of my neighbors were home to borrow one from, then decided they would guestimate it by walking around and measuring how many footsteps, etc. Then they said "It's XYZ sq ft we figure", and then it was up to me to decide if I wanted to accept that estimate. Made me feel uncomfortable to be in that position. The cost/sq ft was quoted before they started ($0.55/sq ft above the 200 sq ft of the Angie's List Deal), I honestly don't know how it compares to others, but going through Angie's List has a "value" as well, of course. Quality of work: Excellent! My deck looks SO much better than it did before! I'm really amazed. Professionalism: Charles was one of two guys who came out, and he was the ultimate professional in demeanor and interactions. Every word and interaction with him seemed to confirm a first impression that he was a sincere and honest guy. He offered to (and did) pressure wash a little of the wood work on the house adjacent to the deck (i.e., more than the deal required). I had some other people out at the time who were hand cleaning something else, and they were having a hard time ... they asked the Sparkle Wash people if they could turn their pressure washer on for them ... Charles and his partner said yes ... EVEN THOUGH they had already packed it up in the truck, they took it out, set it up, and did it for the other guys. Truly above and beyond, IMO. A little weirdness: They had no invoice to give me! Since the deck was larger than the 200 sq ft Angie's list deal, there was an extra cost, but they weren't prepared to invoice me. I told them I didn't want to pay without an invoice in return. They called their office and Sparkle wash will send a receipt by email (or through Angie's List) tomorrow, and I can pay then, but I thought it was a little odd. Would I use them again? I would, if I knew that Charles, or someone as honest and sincere as he seemed to be, was part of the crew. I will be taking bids for staining the deck, and will definitely approach Sparkle Wash for that.
