We had Elite Trade paint our main floor which had oak build ins, baseboards and walls (including vaulted ceilings). They did a great job and came in reasonably priced.
When they quoted, they explained their plan, and let us know what products they were using (including letting us know that some of the products may have a very strong odour, and we should avoid staying in the house those days). The only drawback was that the house was completely under cover with very few access points, which they could have warned us of a bit better.
Overall, we are very impressed by the quality of the work, and happy with the end product.
