exterior paint quote - reasonable?
We're getting the exterior of our ~3k.ft. 2-story home painted. The siding is all vinyl so we're only paining the trim, soffits, & gutters + a large wrap-around porch. Talking with fully licensed & bonded painters, I'm getting quotes in the $3k-$4k range. This covers prep, surface cleaning, paint, and cleanup. Typical quoted paint application methods are spray + back roll using Sherwin Williams Duration (or Ben Moore Aura). Our home has steep roofs so all the 2nd story trim will require a harness. Additionally, the home is past-due for a painting so some scraping, filling, and priming will be needed.
1) The cheaper quotes are doing a single coat of the Duration paint. Is this adequate? I want a long lasting paint job. Should I be insisting on 2 coats? Looking @ Sherwin Williams website, they seem to recommend only 1 coat over existing paint.
2) Is the price reasonable for the work being done? These are A-grade Angie's List companies with good records @ the state licensing board.
