The short answer

How Erosion Happens Around a Home

Rainwater flows across your yard and can carry soil away, especially on slopes or where downspouts dump water close to the foundation. Over time, this creates gullies and low spots that redirect water toward the house. The process is often gradual, so you might not notice it until the damage becomes visible.

In a humid coastal area like Virginia Beach, heavy storms and nor'easters can speed up the process. If the ground around your home loses even a few inches, the soil's support changes, and your foundation may shift. This can lead to uneven settling, which is a common cause of structural cracks.

Signs Your Foundation May Be Affected

Look for cracks in interior walls, sticking doors, or gaps where the foundation meets the siding. Outside, check for exposed foundation edges, sinking walkways, or soil that has pulled away from the walls. These signs often appear gradually, so it helps to inspect your home a couple of times a year.

Uneven settling can also affect plumbing lines and cause water to pool near the base. Catching these signs early gives you a chance to address the cause before the damage grows. If you ignore them, the problems can become more extensive and costly to fix.

  • Cracks in drywall or brickwork
  • Doors or windows that stick
  • Exposed foundation above the soil line
  • Puddles or wet spots near the walls
  • Sloping or uneven ground around the house

What You Can Do to Limit Erosion

Extend downspouts so water discharges several feet from the foundation. Grade the soil so it slopes away from the house, and add mulch or ground cover to hold soil in place. These measures are simple but effective in reducing the amount of water that reaches the base of your home.

Keep gutters clean and check for overflow during heavy rain. Simple steps like these reduce the amount of water that reaches the base of your home and slow erosion. You might also consider installing a rain barrel or a French drain, depending on your yard's layout.

When to Call in the Pros

If you notice foundation cracks or significant soil loss, it's wise to have a professional inspect the structure. A water damage inspection can reveal hidden moisture issues and help you understand the extent of the problem. The pros will assess the situation and recommend the right course of action.

The pros can also address any water damage that has already occurred, such as damp crawl spaces or damaged framing. Acting quickly can prevent more extensive repairs later. Waiting too long might allow the damage to spread, so it's sensible to schedule an inspection as soon as you spot signs.

Repairing Water Damage from Erosion

Erosion often leads to water intrusion, which can damage drywall, flooring, and other materials. If you see stains, soft spots, or mold, those areas need attention. Water damage can weaken the structure and create health concerns, so it's important to handle it promptly.

Depending on the damage, repairs may involve removing wet drywall or flooring, cleaning affected areas, and fixing the source of water. The pros can guide you through the process and help restore your home's condition. They will also advise on steps to prevent future erosion.

Frequently asked questions

How can I tell if erosion is affecting my foundation?

Look for cracks in walls, sticking doors, or gaps between soil and the foundation. Outside, check for exposed roots, bare patches, or water pooling near the house. If you see these signs, consider a professional inspection to assess the severity.

Can I fix soil erosion myself?

For minor issues, you can extend downspouts, regrade soil, and add ground cover. For significant erosion or foundation damage, it's safer to consult the pros. They can assess the situation and recommend the right approach, which might include drainage improvements or structural repairs.

Will my insurance cover erosion damage?

Policies vary, and your insurer decides what is covered. Erosion itself is often excluded, but water damage from a covered event might be included. Check your policy and talk to your insurance company for details.
