Quick, low-risk steps

  1. Stay out of water near electricity and avoid unsafe areas.
  2. Record location, weather timing, and whether plumbing is involved.
  3. Check gutters and visible grading only from safe areas.
  4. Ask every bidder to state the proposed water source.
  5. Compare drainage, discharge, demolition, restoration, and warranty.

Observing Your Home’s Exterior Water Flow

During a rainstorm, walk around your home from a safe distance and watch where water flows. Look for areas where water pools near the foundation or flows toward the house instead of away. These observations can help you identify potential trouble spots, but they do not replace a professional inspection.

Take notes or photos of what you see, including the date and weather conditions. This information can be useful when discussing solutions with a waterproofing contractor. Remember, never enter a flooded basement or touch electrical equipment in wet areas.

  • Watch water flow during rain from a safe location.
  • Note any pooling near the foundation.
  • Check if downspouts are discharging properly.
  • Document with photos and notes for contractor discussions.

Checking and Adjusting Soil Grading

The ground around your home should slope away from the foundation to direct water outward. Over time, soil can settle and create low spots that trap water. You can visually inspect the grading by looking at the slope from the foundation wall outward.

If you notice areas where the ground is flat or slopes toward the house, adding soil to build up the grade may help. However, do not cover siding or create new drainage problems. Always call 811 before any digging to locate underground utilities.

  • Look for soil sloping away from the foundation.
  • Identify low spots where water collects.
  • Add soil to improve slope, but avoid covering siding.
  • Call 811 before any excavation.

Maintaining Gutters and Downspouts

Gutters and downspouts are critical for moving roof water away from your foundation. Clogged gutters can overflow and dump water right next to the house. Clean gutters regularly and ensure downspouts are securely attached and directed away from the foundation.

Downspout extensions or splash blocks can help carry water further from the house. Make sure the discharge point is on a sloped area so water continues to flow away. If you have underground downspout drains, check that they are not clogged and that water exits at the intended location.

  • Clean gutters to prevent overflow.
  • Secure downspouts and direct them away from the house.
  • Use extensions or splash blocks to increase discharge distance.
  • Inspect underground drains for blockages.

When to Call a Professional

While these exterior checks are helpful, some water problems require professional solutions. If you notice persistent wetness, foundation cracks, or water entering the basement despite good exterior maintenance, it’s time to consult a waterproofing expert.

A professional can assess the entire drainage system, including underground issues, and recommend appropriate repairs. They can also evaluate whether interior drainage or sump pump systems are needed. Always get multiple quotes and ask about the proposed water source and warranty.

  • Persistent water issues need professional assessment.
  • Look for foundation cracks or interior dampness.
  • Get multiple quotes and ask about water source and warranty.
  • Consider interior drainage or sump pump if exterior fixes aren't enough.

Common questions

What homeowners ask next

How far should downspouts discharge from the house?

Downspouts should discharge water at least several feet from the foundation, but the exact distance depends on your soil and slope. Extensions or splash blocks can help achieve this. If you have concerns, ask a professional to evaluate your specific situation.

Can I regrade my yard myself?

Minor grading adjustments, like adding soil to low spots, can be a DIY project. However, always call 811 before digging to avoid hitting utilities. For major regrading or if you're unsure, hire a professional to ensure proper slope and drainage.

What if my gutters are clean but water still overflows?

Overflowing gutters may be undersized for your roof area or have improper slope. A professional can assess whether you need larger gutters, additional downspouts, or repairs to the gutter system.
