For accurate paint estimates, what area should be deducted?

For accurate paint estimates, the area that should be deducted is the area of windows. When estimating the total surface area that needs to be painted, it's important to exclude sections that will not be receiving paint, such as windows. This ensures that the estimate reflects only the paintable surfaces, leading to a more accurate calculation of the paint required.

Each of the other areas mentioned—like wallpaper, doors, and trim—has specific considerations in the context of paint estimates, but they aren't typically deducted in the same way. Windows are considered a significant area that directly affects the total square footage to be painted. Therefore, focusing on the area of windows provides a precise measurement to avoid overestimating the amount of paint needed.

Deductions for trim, doors, and wallpaper can be relevant for certain projects, but in the context of estimating paint, windows represent the most straightforward area to exclude to achieve an accurate assessment.
