Painters usually find it hard to estimate the cost of prep work accurately. This is because the amount of work required varies greatly from job to job. The more the damage, the greater the amount of prep work required and hence, greater the cost. Dirty walls covered with grease have to be thoroughly cleaned for the new paint to adhere properly. Wood surfaces should be sanded 5 along the grain and dusted clean ($1.80 per square foot). Any cracks and holes in the drywall will also have to have to be repaired ($1.50 to $3.00 per square foot).

When you're getting quotes for how much to paint a house, you might also want to consider the roof. Expect to pay in the region of $2,800 to $4,500 for roof painting, assuming a 3 bedroom home with a metal, tile or terracotta surface. The existing condition of your roof will play a big part in the final cost. Roof repairs like repointing will add to the final roof painting cost. Broomfield House Painting
Your contractor will sweep or scrub the concrete first with a dry brush, and then clean it thoroughly with trisodium phosphate (TSP) and warm water, then let it dry. TSP is a mostly alkaline solution that does a great job cleaning grease and oil off concrete surfaces. Brush painting concrete siding costs $138 per 100 sq. ft., roll painting costs $50 per 100 sq. ft., and spray painting $32 per 100 sq. ft.
