Why Surface Texture Matters in Spokane

If you're painting a home on the South Hill with heavy stucco or a North Spokane rancher with rough T1-11 siding, your paint usage will be 20-30% higher than a smooth-sided home. Texture creates more surface area that the paint must "get into," reducing the effective coverage of every gallon.

How to Measure Like a Pro

  • 01

    Measure Height: Measure from the ground to the eaves. For gables, measure to the peak and round down slightly to account for the triangular shape.

  • 02

    Measure Length: Measure the total perimeter of the house by adding the length of all four sides.

  • 03

    The "Opening Penalty": For every window, subtract 15 sq ft. For every door, subtract 20 sq ft. This ensures you don't overspend on paint you'll never use.
