Foundation & Exterior Drainage in Kansas City, KS
A lot of wet basements and moving foundations come down to one thing: water sitting against the house. Fixing the drainage is usually the cheapest repair, and sometimes it is the whole fix.
Drainage takes the pressure off
Most wet basements and a lot of foundation movement come down to water sitting against the house.
Signs of a drainage problem
Water is not leaving your foundation fast enough if you see:
- Downspouts that dump right at the foundation or into a splash block that goes nowhere
- Ground that slopes toward the house, or a flowerbed that holds water against the wall
- Standing water or spongy ground near the foundation a day after it rains
- Mulch or soil piled above the top of the foundation wall
- A basement that leaks only during or right after heavy rain
- Erosion channels or settled soil along the foundation
The first ten feet of ground around your house does the most work. If it is not moving water away, everything downstream struggles.
Why drainage fails around Kansas City homes
Clay soil drains slowly, so surface water that is not directed away just pools and soaks straight down next to the foundation. Over years, the backfill soil around a foundation settles and starts sloping back toward the house, reversing the grade the builder set.
Buried footing drains from decades ago clog with silt and roots and stop working, so the water that used to be carried away now builds up against the wall.
Getting water away from the foundation
We start with the cheap, high-impact stuff: extending downspouts well past the foundation, regrading the soil to slope away, and pulling mulch and soil down off the wall. From there, a French drain, a buried downspout system, or a new exterior footing drain handles what surface work cannot.
- Downspout extensions, buried or above ground, discharging away from the house
- Regrading the first several feet to slope away at the right pitch
- French drains to intercept water moving toward the foundation
- Exterior footing drain replacement where the old one has failed
- Yard drains and catch basins for low spots that hold water
Drainage options
Grading and downspouts
The first move and the cheapest. Slope the soil away and carry roof water past the foundation.
French drain
A gravel-and-pipe trench that intercepts water flowing toward the house and carries it to daylight or a basin.
Exterior footing drain
When the original perimeter drain has failed, we excavate and install a new one in clean gravel against the footing.
How the process works
1. Book a visit
Call or send the form and we set a time to come out.
2. Inspection
We look at where your water comes from, how the yard slopes, and where the downspouts end up.
3. Written plan
A clear explanation, the recommended fix, options, and a written price. No pressure.
4. The work
Surface grading and downspout work is often a day. French drains and footing drain replacement take longer and involve excavation.
What drainage work costs
This is usually the most affordable thing on the list. It scales with how much digging is involved:
- Downspout extensions and minor regrading are low cost
- A French drain is priced by the linear foot and how far the outlet is
- Exterior footing drain replacement is the most involved because of the excavation depth
- Hauling in fill, sod, or gravel and restoring landscaping adds to it
- Yard drains and catch basins for problem low spots
Because it is cheaper than structural or interior work, we always check drainage first. Sometimes it is the entire solution.
