WOW! I think the guy I hired read this first and I have photos that would make your skin crawl. Bottom line: he got me for $1900.00. Every single thing he painted had to be completely redone....that's when I discovered he did NOT use the colors I picked, he actually used leftover exterior paint from his mother's house! Because I have pets he said things needed to be sealed first and I did agree to that. What I did NOT agree to was using some kind of foul smelling gray stuff ON MY HARDWOOD FLOORS! THEN he painted them BLACK, telling me that all they were good for was covering over with laminate or carpet. He also dripped and tracked paint all over my ceramic tile floors. PLUS left a wet used paint roller in my garden window and had stuff piled in front so I didn't find it until it had dried. I have no idea how much that is going to cost to repair. Then he left without finishing (thank God) but left the "leftover" paint, uncovered, in the rain. Again, hid it so I didn't immediately find it. Obviously we will be going to court but I doubt if I see a penny from him.
Specify whether the contractor or you will supply the paint. Check Consumer Reports' paint ratings: In its tests, some relatively inexpensive paints performed better than more expensive paints and cost $10 to $20 less per gallon. But keep in mind that most paints will resist cracking, peeling, mold and mildew. Who does the painting — and how well they do it — is more important than what's in the bucket.
If you paint over dirty, oily surfaces, the paint will easily chip or peel off. So before painting, clean grimy areas with a deglosser or heavy-duty cleaner intended for prepaint cleaning. They work well to clean painted, varnished or enameled surfaces to improve the adhesion of the new paint. They’re ideal for cleaning greasy or oily areas like kitchen and bathroom walls and removing hand marks around light switches and doorknobs.
