I hired this person because he was listed on Angie's List. This man claimed he took and passed his contractor's license test after he signed me up for a project (Feb.) that included fixing cracks, painting, repairing a gate, installing a screen door, etc. He said he would charge me the original "handyman" prices. He postponed the start date, brought one worker who fixed a few cracks, repainted the gate terribly, but ruined a dining room ceiling when his worker used silicone in a tube instead of the expansion tape, spray ceiling covering, and paint I had purchased saying this silicone was "better". Then they said they would have to paint the whole ceiling and charge extra. They left holes in the walls and did a sloppy paint job in several places. I just paid them to get them out of my home as I felt intimidated as a senior citizen who is handicapped. I will try to have the main guy come back when I let him know what I need redone. Don't know if he will come back without charging me more.
The speed with which a painter can complete the job will determine its final cost, but time is difficult to estimate. Some painters have more experience and cover a wall faster, but some are more methodical and take more time. Most painters should be able to cover about 100 to 120 square feet of flat surface in an hour, unless they are working on a very large wall. Wood or plaster might reduce that amount to 80 to 100 square feet. You should also consider the time required for a first coat to dry before a second coat may be applied. This will add time as well -- anywhere from one to 48 hours depending on the paint.
Never, never hire "Hanks painting" , he is a scam. He charged me 1800 for an 800 sqft house, with the agreement of painting the gutters. He not only didn't paint the gutters, the paint of the walls and front door is pealing off. He did not sand the door and the wall color is washing off. His people don't know the work and he much less than them since he painted the door.
Getting multiple bids is even more important in the state of Georgia, since contractors of any sort are not required to obtain licensing in order to operate. That makes hiring a painter in the Peach State a bit of a crapshoot, since anybody with a ladder and a paint brush can claim to be professional-grade painter, whether they've got the experience not. This is also why it's not just important to collect multiple bids, but to ask for references and follow up on them. Talking to former customers about their experiences is the best way to go if you want to be absolutely sure you're going to get a quality paint job and with a great price.
