We have a simple formula for pricing out exterior painting projects. We base it off of the floor square footage of the building. The starting price point is currently at $3.25 – $4.25 per square foot for a single story (roughly 14 feet high) building. Based of the floor square footage of the building and the condition of the building.
This price point assumes that the outside walls, window frames, door frames, soffits and fascia are all being painted, but does not include doors, garage doors, shutters, decks or fences.
If we are talking about houses with multiple stories, the price would increase. The higher we have to work, the more risk their is. Other things that can effect the price would be dormers, hard to access areas or dangerous areas to access, siding repairs or other repairs.
As far as material costs go. A good quality gallon of paint is about $80 – $90 and covers about 420 square feet of surface space when sprayed. Spraying does use about 20% more paint, but eliminates the need for multiple coats as each pass over laps the last by 50%.
All said an done. A 1500 square foot single story house with no major repairs to be made, should cost somewhere around $4500 – $6000 all labour and materials factored in, before taxes. This also does not include any fuel costs or equipment rentals that may be associated with the project.
