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!
I was taught to paint by a professional and when estimating the amount of paint needed, I always allow for a second coat just to make sure of coverage. We interviewed a painter who tried to tell me I bought poor quality paint without knowing where I purchased it, and stated he would have to buy all new paint. He had not seen the cans and was just guessing so I asked him where I should buy paint from now on. It was the same place I had purchased my paint and he wanted to charge me an extra 20 a gallon more than what I paid for. Needless to say, I have interviewed numerous painters and they are not all honest. House Painting Westminster Colorado
