The listing photos were taken on a dry week in April. Then you come back for the inspection after three days of rain and the back yard is a sponge, there is a puddle against the foundation, and the crawl space smells like a wet basement. You are in the middle of the option period and every day counts. Here is how we look at a wet yard when someone is deciding whether to buy.
Almost every lot in the Chattanooga area has to deal with water somehow. Clay soil drains slowly, hillside lots shed runoff onto the houses below them, and older neighborhoods were built before anyone thought hard about grading. What matters is whether the water is a nuisance or a threat to the structure. A soft spot in the lawn is a nuisance. Water standing against the foundation or showing up inside the crawl space is a threat, and it is something to negotiate before you close.
Where the downspouts end. If gutters dump a foot from the wall, the roof is putting a lot of water right at the footing. This is the most common cause and the cheapest to fix. See our downspout drainage page.
The grade next to the house. The ground should fall away from the foundation. If it slopes toward the house or has settled into a bowl, water goes where you do not want it.
The neighbors uphill. Look at where runoff enters the lot. A hillside neighbor with a paved driveway aimed at your side yard sends water your way no matter what you do on your side of the line.
Signs of old repairs. Sump pumps, patched block, fresh paint low on the crawl space wall, efflorescence (the white crusty residue on masonry) and rust on metal supports all tell the story the seller may not.
Standing water days after the rain. Ground that stays soggy long after the storm usually needs a real drainage solution, not just a few bags of topsoil. Our page on why a yard stays wet goes through the causes.
If water or humidity is getting under the house, the problem usually started outside. Standing water, wet insulation, sagging subfloor and mold are all signs. Read our guide to crawl space water after rain before you decide how serious it is. Fixing the exterior drainage often solves the interior symptoms.
Depending on the lot, the answer may be extending downspouts to daylight, regrading the soil near the foundation, or a French drain that collects water and carries it somewhere safe. Pricing depends on length, depth, access and where the water can go, so we do not quote a number without seeing the property. Our French drain cost guide explains what drives the price. See the main yard drainage page for the full range of work.
A written estimate gives you something concrete to bring to the seller. You can ask for a repair credit or a price reduction based on a real number instead of a guess, and your agent can use it to decide whether the house still works for you. We can often visit within a day or two, which fits inside a standard inspection window. If the estimate is small, you buy with your eyes open. If it is large, you have time to renegotiate or walk away.
