What home repairs should I complete first?

Work outside in and top down: anything letting water into the house comes first, then safety items, then structure, then systems, and only then cosmetics. Water is the most destructive force in a house, and a $600 flashing repair deferred for two years can become a $15,000 framing and drywall project. Cosmetic work done before the envelope is sound is money you will spend twice.

Suggested order

1. Active water intrusion: Roof, flashing, gutters, grading, plumbing leaks
2. Safety: Electrical hazards, gas, stairs, railings, alarms
3. Structure: Foundation movement, rot, framing damage
4. Systems: HVAC, water heater, panel capacity
5. Cosmetics: Paint, flooring, finishes

What affects the answer

Climate and season. Envelope work has a weather window.
Age of the home and the original build quality.
Whether you are staying, renting or selling.
Insurance requirements, which sometimes force a specific order.

What homeowners often overlook

Grading and downspout extensions are cheap and solve a surprising share of basement moisture.
Attic ventilation problems damage roofs and raise energy costs quietly.
Dryer vents and chimney flues are common fire risks that go years without inspection.
Water heater age — most fail between 8 and 14 years, and replacement on your terms is far cheaper.

Questions to ask before hiring

What is the underlying cause, not just the symptom?
If I only do one thing this year, what should it be?
What will this cost me if I wait two years?

A practical next step

Walk the perimeter of your house after a heavy rain. Most deferred maintenance problems announce themselves within twenty minutes of a storm.
