We had a bad experience with an interior painter years ago, with the crux of the problem being him overcharging us at the end for "extra work" he didn't anticipate. One thing I'd strongly recommend is making sure it's in the contract that any additional work or growth work is estimated and communicated to the owner as soon as it is identified, otherwise the owner is not liable to pay it at the end.
Not only do I agree with what you are saying; but, I will not use Angie's List for referrals again. Their "A" rated painter did some of the exact things they are now warning against; however, they are still rated "A". I sent in a review and it took eight weeks to post it. They allowed the contractor to lie about what happened as a response. I had proof and photos. Angie's List is a scam; instead ask neighbors and friends for referrals!
O'Neil patches shallow holes and divots with Ready Patch because it dries fast, sands smooth, and stays flexible. Deep cracks and rotten spots are best repaired with two-step epoxies, such as those made by Advanced Repair Technology. (For a step-by-step instructions, see Repairing Rot with Epoxy.) The days of using polyester auto-body fillers on wood are over. "They cure too hard," says Portland, Oregon–based painting contractor Kathleen George. "They look good at first, but then they peel away."
