Water Pooling Beside Your Nashville Foundation? Here's What to Check

Water standing against your foundation after rain is worth taking seriously, but it is a drainage symptom first, not proof that the foundation has failed. Work through the checks below before buying a repair. Costs are covered in our foundation repair cost guide.

Safety first

If water is entering quickly, a wall is bowing, or you smell gas or see electrical hazards, leave the area and call emergency services. In Nashville, Metro Water Services lists 615-862-4600 for emergency flooding concerns, 24 hours a day (Nashville.gov).

1. 1Watch where the water goes. Take dated photos during and after rain, noting where it collects and how long it stays.
2. 2Gutters and downspouts. Are they clear? Does each downspout empty several feet from the house? See overflowing gutters.
3. 3Grading. The ground next to the house should slope away from it. Soil that has settled or mulch piled against siding can reverse that.
4. 4Hard surfaces. Patios, sidewalks and driveways that tilt toward the house send runoff to the same spot.
5. 5Neighboring runoff. Note if water arrives from an uphill neighbor.
6. 6Plumbing. A leaking supply line or irrigation head can mimic a rain problem. Check your water meter when nothing is running.

Who is responsible?

Metro Water Services maintains the public stormwater system: street flooding, clogged storm drains, roadside ditches and drains under the roadway. It says runoff from one private property to another, underground springs or groundwater, and sinkholes on private property that do not affect public utilities or roads are not services it manages, and that property owners are responsible for stormwater issues on their private property (Nashville.gov). If you are near a floodplain, Metro lists 615-862-6038 for floodplain questions (Nashville.gov).

When drainage is not the whole story

Call an independent engineer rather than a repair salesperson if you see horizontal or stair-step cracks, bowing walls, cracks that keep widening, or doors and windows that change together. See foundation cracks: when to call an engineer. Water in a crawl space has its own guide: standing water under your home.

Fixes, from least to most involved

• Clean gutters, extend downspouts, correct the grade
• Regrade or add a surface swale, where your property allows it
• Interior drain or sump system, when water keeps entering after exterior fixes
• Exterior waterproofing or excavation, which costs the most and is rarely the first step

Ask any contractor to explain what caused the water and how the proposed work addresses it. Treat a proposal that never mentions drainage with caution.
