What To Fix First After A Home Inspection

Your inspection flagged 30 things. You can't fix all 30 — and you shouldn't try. Here's the exact sequence top buyers use to protect safety, financing, and Year-1 cash.

The Priority Framework

Every inspection finding falls into one of five categories: Safety, Water, Systems, Envelope, or Cosmetic. The sequence below isn't preference — it's the order that minimizes total cost of ownership over the first 24 months. Skipping a tier (especially Water) compounds into much larger problems within a single season.

Days 0–30 — Safety First

These items either present immediate physical risk or block your insurance and financing. They are non-negotiable, regardless of cost. If the seller didn't credit you for them, do them yourself in the first 30 days.

Address any electrical hazards: Federal Pacific panels, exposed wiring, double-tapped breakers. Budget $300–$5,000.
Test and install smoke + CO detectors on every level: Code requirement and insurance condition. Budget $50–$200.
Replace failing water heater (if leaking or 12+ yrs old): Tank failures cause $5K–$15K in water damage. Budget $1,800–$3,500.
Repair active gas leaks immediately: Call utility first — they shut off and inspect for free. Repair: $200–$800.
Add handrails, GFCI outlets, and missing safety hardware: Cheap and required. Budget $200–$800 total.

Days 30–60 — Water Management

Water is the #1 cause of homeowner insurance claims and the fastest source of compounding damage. A $1,500 grading fix in Month 2 prevents a $25,000 mold remediation in Year 3.

Fix all active plumbing leaks: Per-leak repair $150–$500. Address before they reach subfloor.
Extend downspouts 6+ ft from foundation: $20–$200 per downspout. Highest-ROI repair on this entire list.
Regrade soil to slope away from foundation: $1,500–$5,000. Eliminates most basement water issues.
Service or install sump pump with battery backup: $400–$900. One storm can flood without backup.
Repair roof flashing and any active leaks: $300–$2,000. Don't wait for full replacement to seal active leaks.

Months 3–6 — End-Of-Life Systems

Systems already past 90% of their expected life are not maintenance items — they are funded replacements. Plan and execute these in Months 3–6 to avoid emergency-pricing premiums (15–40% higher than scheduled work).

Replace HVAC if 18+ yrs (furnace) or 14+ yrs (AC): Combined: $9,000–$18,000. Schedule in shoulder season for best pricing.
Replace roof if under 2 yrs of life remaining: $9,000–$25,000. Bundle with attic insulation top-up.
Re-pipe polybutylene or galvanized plumbing: $4,000–$10,000. Required by most insurance carriers.
Replace electrical panel if Federal Pacific/Zinsco/Pushmatic: $2,500–$5,000. Pair with panel-load assessment if adding EV or heat pump.

Months 6–12 — Envelope & Efficiency

By this point, the home is safe, dry, and modernized. Envelope work pays back in monthly utility savings and comfort, typically 4–8 year ROI.

Top up attic insulation to R-49+: $1,500–$4,000. Saves $300–$700/yr in temperate climates.
Replace failed window seals: $400–$900 per window. Address worst rooms first.
Repair siding, trim, and exterior caulking: $1,500–$10,000. Critical before next freeze cycle.
Service chimney, replace cap and flashing: $300–$2,500.

Cost range

Typical 12-month repair sequence cost: $18,000–$45,000
