Best approach: Split maintenance across the year. A short seasonal walk-through is easier to keep up with than one overwhelming annual inspection.
Spring
- Inspect the roof, flashing and siding for winter damage.
- Clean gutters and confirm downspouts discharge away from the foundation.
- Check exterior drainage, grading and low spots.
- Service air conditioning before hot weather.
- Test outdoor faucets and irrigation for leaks.
Summer
- Inspect decks, railings, fences and exterior steps.
- Watch for plumbing leaks and moisture in basements or crawlspaces.
- Trim vegetation away from siding, roof edges and outdoor equipment.
- Review cooling costs and replace HVAC filters as needed.
Fall
- Clean gutters after leaves drop.
- Service heating equipment and inspect vents.
- Seal obvious air leaks around doors and windows.
- Disconnect hoses and winterize vulnerable exterior plumbing.
- Check smoke and carbon monoxide alarms.
Winter
- Watch exposed plumbing during freezing weather.
- Check attic or ceiling areas for signs of roof leaks.
- Keep exterior exhaust vents clear of snow or debris.
- Review emergency supplies and know your utility shutoffs.
Monthly five-minute check
Look under sinks, around toilets and near water-using appliances for moisture. Listen for unusual HVAC or plumbing sounds. Check one filter, drain or safety device. Small observations are often what catch developing problems early.
Safety note: Roof access, electrical panels, combustion appliances and structural concerns can involve serious hazards. Use qualified professionals when inspection or repair is outside your experience.
