What common home repairs cost — a ballpark

Big-ticket replacements (US industry estimates)

Water heater (tank) roughly $881–$1,825; tankless $1,400–$3,900. Gas furnace $3,500–$7,500; AC condenser about $1,200–$4,200; furnace and AC together $5,000–$12,500. A full asphalt roof commonly $5,700–$12,000 (more on larger homes). Windows $300–$2,500 per window installed. All are ranges from contractor-lead surveys — treat them as ballparks and get quotes.

Smaller repairs

Roof repair averages around $1,171 (minor $150–$450, major several thousand). A running-toilet or faucet repair by a plumber runs $150–$400. A sump pump install averages about $1,400. An HVAC diagnostic visit is $70–$250. Many of these — the toilet especially — are cheaper DIY; see the linked pages.

Common questions

Why are these ranges so wide?

Local labor rates, material grade, home size, access, and add-ons like permits and disposal all move the number. A national estimate can't reflect your home — a real quote can.

How much should I keep for repairs?

A common planning rule is about 1% of the home's value per year set aside for maintenance and repairs. See the maintenance-budget page.
