The best way to assess a contractor’s estimate is to approximate one yourself . Whether you do your own work or not, you should estimate the amount of time and materials needed. Use these simple guidelines:

Calculating The Size Of your House

Step 1: Calculate the size of the house

1. Measure the width of the house.Run a tape measure along the base
2. Measure the height of the house.To measure the height of a two- story house, pick a point about half way up, measure to that point, then double the result.
3. Calculate the square footage of the house.You don’t need to make deductions for doors, as there are only a few. Use common sense to deduct footage for windows. Make adjustments for large surfaces on the house not to be painted.

Step 2: Estimate Time.

Aside from the actual painting, you need to include time for daily setup, cleanup, breaks, meals, runs to store for materials, and weather interruptions.
