I agree James, I know why they do that. in fact, we EXPECT them to find water damage behind the walls, so we already expect the end price to be higher than the estimate.
craig, no, I didn't know about that list. I used Angie's list. it wasn't expensive. $10/year.
I did try using "the Good Contractors List" but there were very few to choose from on there in my area. ONE, IIRC, was in Ft. Worth, 2 or 3 listed for Dallas and that was all in the whole metroplex area.
