Prepping a house costs anywhere from $0.50 to $2.50 per square foot. This is almost always included in the total project price. However, the DIYer might negotiate some discounts for completing this work on their own. Be warned, proper prep is key to the quality and durability of the finish. If you do this work yourself, the contractor might no guarantee to finished product.
The national average cost for an interior painter ranges between $450 and $900. Interior painters can tackle everything from complete color makeovers in each of your rooms to touching up an accent wall to painting pieces of furniture. The square footage and complexity of the project, along with the materials needed, are the main factors that will affect cost. Other factors include whether you supply the paint yourself or want the painter to do so, whether you move the furniture and do the prep work or ask them to do it, and whether any repair work is needed on the walls. Painting the ceiling and the trim will also have an effect on cost. The type of paint you choose can also raise or lower your house painting cost. A gallon of paint may range from $20 to over $100, depending on quality and brand. Ask your painter if they charge per hour or per square foot, and how much you can save by doing prep work (moving furniture, etc.) yourself. Westminster House Painting
