Paint doesn't fail from age alone — it fails from what's underneath it. Prep work and moisture control determine the real lifespan more than the paint itself.
Pick a task and a state — the band already has the local cost index applied, the same way it's calculated everywhere else on the site.
National baseline, before your state's regional index. Use the calculator above for a state-adjusted number, or browse by state.
Most painting bills trace back to one of these — knowing the typical lifespan is the difference between an expected replacement and a surprise.
Sun-facing walls wear faster than shaded ones — the same house can need touch-ups on one side well before the other.
High-traffic rooms (kitchens, hallways) show wear years before bedrooms do.
The first thing to fail around windows and trim — and the cheapest to stay ahead of.
More than the paint brand, this is what separates a 5-year job from a 12-year job.
Usually redone alongside the main exterior repaint rather than on its own schedule.
The common ways these systems fail, in the order they tend to show up.
South- and west-facing exteriors fade and chalk noticeably faster than shaded sides of the same house.
Peeling or blistering paint is almost always a moisture problem first, a paint problem second — repainting without fixing the source just delays the same failure.
Paint applied over unwashed, unsanded, or unprimed surfaces fails years earlier than the same paint applied correctly.
Hallways, stair walls, and kitchens show scuffing and dulling long before a full repaint is otherwise due.
Small gaps at trim and window joints let water behind the paint film, accelerating peeling nearby.
Worth knowing before you agree to anything — what's actually happening in the system, and why the market around it prices the way it does.
The Science
Peeling and blistering are almost always a moisture or adhesion problem in the substrate underneath — not a flaw in the paint itself.
This is why the sun-facing side of a house visibly fades and chalks years before the shaded side of the same house does.
It lets a topcoat adhere to surfaces — bare wood, glossy trim, masonry — that paint alone wouldn't stick to reliably on its own.
Paint can feel dry to the touch while still curing underneath for days — early handling during that window is what causes marks that only show up later.
The Economics
Prep work — scraping, sanding, caulking, masking — is where most billable hours go, which is why two jobs using the same paint can cost very differently.
Most regions have a real window where temperature and humidity allow proper cure, which concentrates demand — and pricing — into that window.
Going from a dark color to a light one, or vice versa, usually requires extra coats — a real cost driver, not an upsell.
The same six-input breakdown published on every hub — parts, labor, overhead, and margin, not hidden behind a single number.
Roughly ten percent goes to shop margin — what a good shop clears to still be answering the phone the next time you call. See the full methodology for how every input is calculated.

Nationally, interior room repaint, 12×14 runs $380–$780 (per room), with a typical (median) price of $545. Prices vary by state; see your state's page below for regional ranges.
Nationally, exterior repaint, 2,000 sq ft runs $4,200–$9,400 (per house), with a typical (median) price of $6,300. Prices vary by state; see your state's page below for regional ranges.
Each range is built from public data: BLS labor rates, material costs and a state cost index. The full method is published at fairrateindex.com/method, and no contractor can pay to change a number.
Every state page has painting prices with that state's regional index already applied.
Know what's fair. Before the truck shows up.
The Fair Rate Index publishes independent estimates for homeowners and vehicle owners. Figures are modeled from public data and are not quotes, offers, or recommendations to any contractor about what to charge. Members and business customers fund the free index; nobody can pay to change a number. Always get a written estimate before work begins.
