A well-done exterior paint job protects your home from weather and boosts curb appeal. This guide covers when painting is needed, what affects cost and durability, key prep steps, and what to ask before you book a pro.
Exterior painting is more than color. Good projects start with inspection and surface prep: washing, scraping failing paint, sanding, caulking gaps, spot-priming bare or stained areas, and protecting landscaping and fixtures. Application may use brushes, rollers, or sprayers, with back-brushing/back-rolling to ensure coverage.
Project scope and price are shaped by siding type, height and access, condition of existing paint, and how much prep and repair are needed. Paint systems and sheen choices also affect longevity and appearance. Homes in communities with HOAs may need color approval in advance.
Before hiring, ask about the contractor's prep process, how they handle moisture issues and repairs, the coating system (primer and finish coats), application methods, daily cleanup, warranty terms, and what is excluded (e.g., wood rot repair or gutter fixes). Request a written scope with surface counts, prep steps, product names, number of coats, and change-order rules.
If paint is failing but the substrate is sound, thorough prep and a quality primer and topcoats can restore protection. Spot repairs like scraping, sanding, caulking, and replacing isolated trim pieces are common. Stained or tannin-rich woods and rust-prone metals often need stain-blocking or rust-inhibiting primers before finish coats.
If there is widespread wood rot, moisture intrusion from leaks, or failing siding, replace or repair those components before painting. Painting over moisture problems, active leaks, mold, or unstable surfaces often leads to early failure, even with premium paint. Ask whether your contractor will repair or coordinate repairs, and how they will verify surfaces are dry and ready.
Home size and height, siding type, current paint condition, amount of scraping and repairs, number of coats, and product quality are major factors. Access challenges and detailed trim can add time and cost.
Most exteriors benefit from cleaning to remove dirt and mildew, followed by scraping, sanding, and spot-priming bare or stained areas. Some surfaces and stains require specific primers for adhesion and stain blocking.
Sprayers can speed application and provide even coverage, but quality depends on prep and technique. Many pros spray and then back-brush or back-roll to work paint into the surface and improve adhesion.
Choose a contractor who documents prep steps, uses appropriate primers, applies the specified number of coats, manages moisture issues, and performs a final walkthrough. Look for clear scope, product names, and warranty terms in writing.
If you have an HOA, you may need to submit colors for approval before work begins. Ask about timelines and any restricted palettes.
Lifespan varies by climate, sun exposure, prep quality, and products. Ask your contractor about the expected maintenance cycle for your home and region and what their workmanship warranty covers.
