Maintenance

Monthly Home Maintenance Checklist

A repeatable monthly inspection that catches water, electrical, ventilation and safety problems early.

Difficulty: BeginnerTime: 45–75 minutesTypical cost: $0
Safety first: This checklist is observational. Do not open electrical, gas, combustion or sealed appliance components.

Common symptoms

Likely causes

Start with the simplest observable cause and avoid replacing parts until the failure has been identified.

Tools and materials

Step-by-step procedure

  1. Look below sinks, around toilets and near appliances for moisture, staining or swollen materials.
  2. Test accessible GFCI and AFCI devices using their built-in buttons according to manufacturer instructions.
  3. Inspect the furnace or air-handler filter and replace it when loaded.
  4. Check dryer performance and confirm the exterior vent opens during operation.
  5. Test smoke and carbon-monoxide alarms and review their replacement dates.
  6. Inspect exterior grading, downspout discharge and visible roof or siding damage from the ground.
  7. Operate rarely used shutoff valves only when their condition and local guidance make this appropriate.
  8. Record findings, photos and repairs in a home maintenance log.
Field tip: Take photos from the same location each month; side-by-side comparison makes slow changes easier to notice.

Common mistakes to avoid

Verify the repair

Test the repaired component through several normal operating cycles. Watch, listen and feel for leaks, heat, movement, unusual noise or odour. Stop immediately if the condition worsens. Document the work and retain part numbers, receipts and manufacturer instructions for future maintenance.

When to call a professional

Arrange qualified service for gas odour, electrical heat or arcing, active water intrusion, structural movement or alarm activation.
