The short answer

How Pool Water Reaches Your Home

Pool water moves through soil the same way rain does. If the ground around the pool is saturated, or if a liner or pump leaks, water can migrate toward lower areas, including your foundation. Clay-heavy soil, common in many regions, holds moisture and can channel it sideways for surprising distances.

The water may enter through cracks in your foundation, gaps around pipes, or the joint where the floor meets the wall. Once inside, it can soak drywall, wood framing, and insulation. Even a slow leak can cause visible staining and warping over time.

Signs of Water Damage to Look For

Check for discolored patches on walls or ceilings, especially near the floor or where walls meet the ceiling. Peeling or bubbling paint and wallpaper often signal moisture behind the surface. A musty smell in a basement or crawlspace can mean dampness has been present for a while.

Also inspect baseboards and flooring for swelling or cupping. If you have a crawlspace, look for standing water or wet insulation. Catching these signs early helps you limit the repair scope and gives you useful information when you talk with your neighbor or your insurance company.

  • Damp or dark spots on drywall
  • Warped or buckled floorboards
  • Musty odor in basements or crawlspaces
  • Cracks in the foundation that feel damp
  • Peeling paint or wallpaper near the floor
  • Standing water in a crawlspace or sump pit

What to Do Right Away

First, protect your belongings. Move furniture, boxes, and electronics away from the affected area. If you can, remove wet carpets or rugs to let the floor dry. Run a dehumidifier or fans to lower humidity, but avoid pointing them at electrical outlets or fixtures.

Next, document the damage with photos and notes. Keep a record of dates and any communication with your neighbor. This helps you and your insurance company understand what happened. If you suspect a serious leak, consider turning off your own water supply to rule out a plumbing issue.

When to Call Local Water Damage Pros

If the water has soaked into drywall, insulation, or structural wood, drying it out properly is a job for local water damage pros. They have moisture meters and drying equipment that can reach deep into wall cavities. Attempting to dry it yourself can leave hidden moisture that leads to mold or rot.

The pros can also identify the source of the water and advise on repairs. They may need to remove sections of drywall or insulation to fully dry the framing. Their work usually involves drying, cleaning, and sometimes applying antimicrobial treatments to prevent mold growth.

Working with Your Neighbor and Insurance

Talk with your neighbor calmly and share what you have found. They may not know their pool is leaking. If the damage is significant, your insurance company can help you understand your coverage. Policies vary, and your insurer decides what is covered.

Ask your insurance company about the claims process and what documentation you need. You may also want to check your own policy for coverage of water seepage or subsurface water. A professional inspection can provide a clear picture of the damage, which is useful for any claim.

Frequently asked questions

Can I dry the wall myself with a fan?

A fan can help surface moisture, but it won't reach deep into wall cavities. If the drywall is wet behind the surface, you may need to cut openings to allow air circulation. The pros have professional drying equipment that can handle this more effectively.

What if the pool is still leaking?

Ask your neighbor to check the pool for leaks and repair them. If they don't act, you can contact your local building department about potential code violations. Keep records of your requests in case you need to involve your insurance company.

Will my insurance cover this?

Coverage depends on your policy and the cause of the damage. Some policies cover sudden and accidental water damage, but not gradual seepage. Policies vary, and your insurer decides what is covered. Check your policy documents or call your insurance company to ask.
