If your home was built before 1978, there is a good chance that lead paint was used in its construction. Scraping, sanding, or removing old paint can release toxic lead dust which can cause serious illness in children and pregnant women. Special handling is required when working with lead-based paints. If lead paint is present in your home, you will need to hire a lead-certified painting contractor or lead abatement contractor. Before getting started with your exterior painting project, consult your local building authority or visit www.epa.gov for more information.
The cost to paint metal siding -- most commonly aluminum and galvanized steel -- will depend on a variety of factors. In some instances, a simple cleaning will suffice to prepare metal siding for painting. In worst cases, painting professionals will need to repair metal that is rusted, damaged or missing pieces due to climate conditions. In the case of severe damage, a professional will have to remove the old finish and paint to get to the original layer, which will add on to the final price. When you add the actual painting of the metal siding, you might be looking at a final bill between $400 (~250 sq. ft.) and $1,500 (~1,000 sq. ft.).
The best time of the year to paint your home is typically in late spring and early summer when it’s warm outside and moisture is low. This can change based on your geographic location. For example, fall can be a good time to paint in California when the difference between high and low temperatures is low. Your painter will select the optimal time to start your exterior painting project.
