Grading & Downspouts in Knoxville, TN
Getting the ground around your house to fall the right way
The ground around a house should fall away from it, roughly six inches over the first ten feet. On a lot of Knoxville homes that slope quietly reversed years ago. Backfill along the foundation settles, flower beds get topped up with fresh mulch, a walkway sinks a little, and eventually the soil beside the wall forms a shallow dish that holds water against the block. Add a gutter overflowing at the same corner every storm and the crawl space has a steady supply. Grading work puts the fall back. We bring in the right soil, shape it away from the wall, and pull back beds and mulch that have crept up toward the vents.

How grading & downspouts work around Knoxville
Downspouts are part of the same job. Gutters that are pitched wrong, clogged or too small for the roof above them spill at the corners, and downspouts that empty right at the footing undo any grading in front of them. We get them carrying water out onto ground that falls away. It's the least glamorous work we do and often the best value, which is why it gets looked at before any drain is quoted. It does have limits. Grading handles rain that lands near the house. It won't stop groundwater moving through the soil underneath, and on a steep or tight lot there may be no room to build enough fall.
Knoxville's ground shapes how far this can go. Older homes in town often sit close to their neighbors, with little yard to work with, and limestone near the surface can limit how much soil gets moved on some lots. Water that soaks in close to a house on karst can find a seam and travel, so the first ten feet matter more than they look. Grading is also maintenance: soil settles again and beds get topped up, so expect to keep an eye on it. At the free on-site estimate we walk the perimeter, check the fall on each side, see where every downspout empties, compare soil and mulch height against the vents, and note where water pools.
Worth knowing: Grading is maintenance as much as a repair: beds get topped up, soil settles again. Expect to keep an eye on it over the years.

Grading & Downspouts questions
What homeowners ask about grading & downspouts
Our flower beds are piled higher than the crawl space vents. Is that a problem?
It is. Soil or mulch that high lets rain run straight into the vents and holds moisture against the wall. Pulling the beds down below the vents and reshaping them to slope away is one of the cheapest fixes there is.
I can't tell by eye whether our yard slopes toward the house. How do you check it?
We measure the fall from the foundation outward along each side with a level and a straight run of string or board. The target is roughly six inches of drop over the first ten feet. You can get a rough read yourself by watching where water sits after a heavy rain.
We were thinking of piling topsoil against the foundation ourselves. Anything we should watch out for?
Keep the soil below the vents and well under any siding, and shape it so it actually falls away from the wall. Firm it down a little, check it after the first heavy rain, and keep mulch thin near the block. Loose fill that holds water right against the house works against you.
Our gutters overflow at the same corner every time it storms. Is that a gutter problem or a downspout problem?
It could be either. A corner that always overflows usually has a clogged or undersized downspout, a gutter pitched away from the outlet, or a downspout that can't keep up with the roof area feeding it. We find which it is, fix the cause, and make sure the downspout empties well away from the wall.
We reseeded the yard last fall. How much of the lawn does regrading disturb?
Only the strip being reshaped, which is usually the first several feet out from the foundation on the affected sides. That area will need reseeding or sod afterward. We'll show you the extent at the estimate so you can plan around it.
Once our yard's regraded, will I ever have to redo it?
Think of it as maintenance. Soil settles again, beds get topped up, and the fall can slowly shrink over the years. Checking it every so often and keeping mulch and soil low near the wall keeps it working.
The lot behind our house slopes down toward it. Can grading alone fix that?
Sometimes there's room to reshape the ground behind the house so water turns aside. On a steep slope there often isn't, and a swale or exterior drain may be needed alongside it. We'll tell you what grading can realistically do on your lot.
Our sidewalk has sunk and now tilts toward the house. Who handles that?
Leveling or replacing concrete is a job for a concrete contractor, and it's outside what we do. Our part is the water it sends at the wall, which a diverter along its edge or grading around it can deal with. We'll point out what's happening at the estimate.
I'm tired of cleaning gutters. Would gutter guards help keep our crawl space dry?
They can cut down on overflow by keeping leaves out, which helps where a corner spills in every storm. They do nothing about where the downspouts empty or how the ground slopes. Guards also need occasional cleaning themselves.
We built a raised garden bed against the back wall. Is that sending water into our crawl space?
It can be. A bed against the foundation holds wet soil right at the block, and every time you water it, some of that soaks toward the footing. Moving it a few feet out, or lining it and draining it away from the wall, usually solves it.
