Don't hesitate to ask all the questions you need to feel comfortable hiring a professional. You can also ask 3-4 professionals to make sure you have the right quote in mind. You must make sure they have a warranty or some kind of paperwork stipulating the quality of their jobs. Insurance is also a #1 priority to consider, as damage can happen in the process of painting.
Appliance delivery guys put a 1 inch gouge in my recently painted 15 foot foyer wall and really hacked up the base rail. Does the entire wall have to be repainted or can the gouge be repaired and blended. Wall was painted 10 months ago? Any thoughts on pricing to repair gouges in base rail with epoxy and repaint? It’s another 8 ft long and is 8” x 1” pine, painted white. Thx.
Whether doing it yourself or hiring someone, buy the best quality paint you can afford; it lasts longer and in some situations requires only one coat of paint instead of two. Painting a room usually involves prep work, primer and latex or alkyd paints with a range of finishes. HGTV.com gives a quick overview  as well as a list of painting dos and don'ts .
"C&A was not the cheapest company, but it was the only one that offered full service (removal of waste and carpet installation), and showed some real interest. Furthermore, the sales representative was on-time, polite, and always available. The finished job looks great, the crew was on top of its work, and they left after cleaning thoroughly, which not that many companies care to do. I highly recommend them."
