Exterior Drainage (First Line of Defense)
- Grading: Soil should slope away from foundation walls at least 6 inches over 10 feet
- Gutters: Clean twice yearly; ensure gutters are properly pitched toward downspouts
- Downspout extensions: Direct water at least 10 feet from the foundation
- Window wells: Install covers on basement window wells
Sump Pump Maintenance
- Test annually by pouring water into the pit to trigger the float switch
- Install a battery backup system. Most basement flooding occurs during power outages
- Professional inspection every 3–5 years; replace pumps every 7–10 years
Interior Humidity Control
- Maintain humidity below 50% year-round using a dehumidifier
- Ensure dryer vents exhaust outside (not into the basement)
- Insulate cold water pipes to prevent condensation
Plumbing Inspection Schedule
- Water heater: inspect annually; replace every 8–12 years
- Washing machine hoses: replace every 5 years; use braided stainless steel hoses
- Main water shutoff valve: test annually to ensure it operates properly
