Some siding on older homes might need so much repair that it is more cost-effective to replace the siding rather than repair it all and then paint over it. Expect to pay between $1,550 and $3,050 for the removal and disposal of old siding and $4,000 to $14,000 for new siding and installation. Expect to pay more if the wood underneath is wet and rotten and needs structural repair work.
Like the rest of your home’s exterior, you should start from the top down when painting exterior trim. If your window sills look particularly weather-beaten, you might want to give them a second or third coat of paint. When painting doors, paint the panels first, then the rails and stiles, and finally the edges. For more details, read up on trim painting guidelines.
Determine the coverage area for each color and estimate the number of gallons you'll need for each. For odd walls with angled ceilings, make your best guess. If you're not comfortable doing this, measure the wall at its highest height and multiply that by its width. Now subtract the lowest height from the highest height, multiply that number by the width, cut that answer in half, and finally subtract that new number from the original height by width. That should give you the wall area.
A single gallon of paint can run anywhere from $20 to $80 per gallon. Professionals get a contractor discount of anywhere from 25 to 50 percent. For rough siding, like stucco, you’ll need to use 10% to 20% more paint. Some textures, like wood and stucco, require extra paint because they have more surface to cover in a tiny area compared to smooth siding. Use the highest quality exterior paint your budget will allow for your project. It will look the nicest and save you money by offering better coverage and durability. Better coverage means fewer coats and fewer work hours. You’ll also go a few years longer without needing to shell out more cash for a new coat. How do you know how much paint you're paying for? Here's some helpful math:
