We had our wood deck power-washed, sanded, and stained with two coats of semi-transparent stain by CertaPro. They were selected because they had the lowest bid. When it looked like it might not be possible to complete the job in the original timeframe CertaPro had proposed, the franchise owner stepped in to do the job personally. He took the time to explain every step of the process, and the pros and cons of various options; I never felt like I was being up-sold to a more expensive option. When the colour on a few boards came out lighter than the rest, CertaPro invested additional time fixing the problem and ensuring the job was completed to our satisfaction. And they even stained some vertical posts which were not included in the estimate at no extra charge. I wouldn't hesitate to recommend this very professional contractor.
