Why are painting quotes so different from each other?

Usually because they describe different work. One may include two coats over full preparation and premium paint while another assumes a single coat over sound existing paint. Compare the scope before the price.

Should I supply the paint?

Some painters allow it, others will not warrant work using materials they did not select. Ask early, because it changes both the price and the warranty.

House painting cost: what drives the price

The factors that move a house painting quote up or down, how painters build an estimate, and how to compare two quotes that are not describing the same work.

Painting quotes are driven by surface area, condition, access and finish. Preparation is often the largest variable: scraping, sanding, filling, priming and repairing before any finish coat goes on. Height, trim detail, the number of colours, the number of coats and the paint grade all move the number. Costs vary based on location, project size, materials, complexity, access and the provider you hire.

Key points

Preparation, not paint, is usually where the hours go.
Two quotes are only comparable when they list the same prep, the same number of coats and the same product.
Ask what is excluded. Repairs found during prep are the most common surprise.

What painters price

Surface area and the number of separate surfaces such as walls, ceilings, trim, doors and rails
Condition, including scraping, sanding, filling, caulking, patching and priming
Access, meaning ladders, scaffolding, height and difficult ground
Coats, since one coat over a strong colour change rarely covers
Paint grade and sheen
Masking, protection, moving and covering furniture, and cleanup

Interior versus exterior

Interior work is priced heavily on room count, ceiling height and trim detail, and it is affected by how much furniture has to be moved and protected. Exterior work is more affected by substrate condition, weather windows, height and access. Exterior repainting also carries a real risk of finding rot or failed caulking once scraping starts.

Find a painter

Lead paint and older homes

Homes built before 1978 may contain lead based paint, and disturbing it is regulated. Ask whether the contractor is certified for lead safe work practices and how testing and containment are handled. This is a safety and compliance question, not an upsell.

How to compare quotes

Ask each painter for the same defined scope in writing
Confirm the number of coats and the specific product and sheen
Confirm what preparation is included and what would be extra
Confirm who moves furniture and who cleans up
Confirm the labour warranty and how touch ups are handled
