Older Home (Pre-1980) Maintenance Checklist — Onalaska, Washington

Required before any renovation in pre-1978 homes. Use EPA-approved test kits or hire a certified inspector.

Common in popcorn ceilings, floor tiles, pipe insulation, and siding before 1980. Do not disturb — test first.

Knob-and-tube wiring, aluminum wiring, and undersized panels are common. Have an electrician assess your system.

Galvanized pipes corrode and reduce water pressure over time. Lead solder was used until 1986. Consider testing water.

Older homes are more prone to settling. Check for new cracks, sticking doors/windows, and sloping floors.

Many older homes have minimal insulation. Adding attic and wall insulation dramatically improves comfort and efficiency.

Older homes often have irreplaceable wood details. Repair and refinish rather than replace.
