After you have done the multiplication, subtract about 40 sq feet per window, and about 60 sq feet per door. Divide by 400 (interior paint covers 400 sq feet per gallon). The number that remains, is how many gallons you will need. If doing multiple wall colors, then you should do this process for each room (or sets of rooms) with a particular color.
The other difficult part is getting a painting contractor to show up. While this generalization does not apply to every painter, you can rarely get a paint contractor to show up to look at the house and to later produce a written estimate. It's hardly the fault of the painting contractors; it is a combination of the contractors being smaller operations along with a high demand for their work. Denver House Painting
Most of a projects price is the cost of labor at $25 to $75 per hour. However, most contractors bid out based on the entire project which includes all work hours. Hourly rates are only useful if your pro asks to do the job as “time and materials.” However, be wary of this pricing structure, it usually shows the contractor is uncertain how long the project will take.

I hired Israel General Painting to paint the exterior of my house. He helped with color schemes and also getting samples to test. As we decided on the colors he washed and prepared the house then primed and painted. Did a great job. He was very flexible with color changes. He also did a different color around doors and windows with no extra charge. He also primed and painted the porch. He was quite punctual unless my experience with other contractors, which was really good. After the painting was done he also cleaned the roof and around the house and putting back the things in place. We ended up with him painting a room in the house as well (of course that’s with a new quote). I highly recommend Israel General Painting for your painting needs. I plan on hiring Israel again to paint the interior of the rest of my house next year! Home Painters Denver CO
