Foundation seepage is groundwater moving through cracks, joints or the wall-floor seam and into a basement. In Olathe it usually follows a wet spring, when the clay soil around the house holds water against the wall. A crew dries the wall cavity, floor and contents, and checks for hidden moisture before any repairs are quoted.
Seepage is the slow kind of basement water. It does not come from a burst line or a backed-up drain. It comes through the foundation itself, showing up as a damp band along the wall, a white crust on the block, or a film of water along the joint where the wall meets the floor. In Olathe the usual setting is a poured wall in a 1980s or later subdivision, usually finished and fitted with drain tile and a sump pit, or a block or stone cellar in an older house. Both can seep, but they seep for different reasons. The cleanup starts the same way: find the wet materials, get air moving, and dry them before mold has a chance.
The ground under much of the county explains the timing. Grundy silt loam, mapped widely across Johnson County, is a somewhat poorly drained soil formed in loess, with a subsoil that is 42 to 48 percent clay. The USDA's official series description puts a perched saturated zone within 0.3 to 1.0 meters of the surface in the wettest years. That means a wet March can leave water sitting against a basement wall that was dry in August. Smectitic clays also shrink as they dry and swell as they take on water, so the gaps around a foundation open in late summer and close again in spring. The path water takes changes through the year.
When a crew comes out, the first job is the wet area and the people in the house, not the wall. Phones are answered 24/7 and a crew is dispatched as fast as one is available. On the first call, describe where the water shows, whether it is clear or dirty, and whether it followed rain or a thaw. For the drying itself, see the basement flooding page.
Do not step into standing water near the electrical panel, the furnace, the water heater or a basement outlet. Shut off power at the breaker only if you can reach it while dry, and call the utility if you cannot. Do not run a wet-vac or a plug-in dehumidifier in standing water. Do not cut drywall, pull carpet or seal a crack before you have photographed the wall and floor. Treat anything that came in through a floor drain as contaminated, and keep children and pets out of that room until it is cleaned.
Phones are answered 24/7 and a crew is dispatched as fast as one is available. Say where the water shows, such as the wall, a corner, the joint or the floor, and whether it followed rain or snowmelt. If a supply line is also involved, the crew can help you find the shut-off.
The technician checks the electrical panel, the furnace, the water heater and any outlet near standing water before anyone works close to them. Wet rugs, boxes and stored items are moved out of the way so air can reach the wall. Anything electrical standing in water stays untouched until it has been checked.
Moisture meters and thermal imaging show how far water has traveled, often behind drywall, under trim and along the sill plate. Readings are taken at the wall base, the wall-floor joint and inside the cavity. Finishes are opened only as far as the readings require.
Air movers and dehumidifiers go in, and readings are taken again until the materials are dry. EPA guidance is to dry water-damaged areas and items within 24 to 48 hours, because mold can grow on wood, drywall and carpet left wet for more than 24 hours. Drying runs as long as the readings need, not for a set number of days.
Photos and moisture readings are given to you for your insurer or your own records. Repairs after drying, such as new drywall, paint or trim, are quoted separately after someone has seen the wet area. Foundation waterproofing and grading are not offered here, and any contractor you hire can be checked in the county's contractor search.
Seepage comes through the wall or floor from the ground outside, so it is usually slow and tied to rain. A burst line or sewer backup starts inside the house and can be fast. Whether the water is clean or dirty, and whether it followed rain, is the first thing to tell the crew.
A supply leak has a source you can close at the shut-off. Seepage does not. Running the sump pump or mopping the floor buys time while the wall keeps passing water. Staining that appears weeks after a storm is common with seepage and can be mistaken for a leak from above.
Sewer backup and sump pump failure are different problems with different coverage and reporting paths. If water came up a floor drain, see the sewage backup page. If you cannot tell which it is, describe what you see and let the crew sort it out on site.
The soil around the house holds water longer than it drains. Grundy silt loam has a clay subsoil that can keep a perched water table close to the surface in the wettest years, and the wall takes the pressure. Dry summers shrink the clay and open gaps that the next wet season fills.
The USDA describes Grundy silt loam as somewhat poorly drained, with a clay subsoil that slows water down rather than letting it drain away. In a wet March, the perched saturated zone can rise to within 0.3 to 1.0 meters of the surface, and the basement wall sits in it. That is why a basement that was dry in August can start seeping in March without any new crack.
Smectitic clays change volume with moisture, so the same soil that pulls away from a foundation in a dry late summer pushes back in spring. The 2017 floods on Indian Creek came in late July and late August, showing how fast creek-side saturation can build. For the longer story, see the expansive clay guide.
You can run air moving and a dehumidifier to slow things down. A fan in the room does not dry a wall cavity behind drywall or a sill plate, though. Materials that stay wet for more than 24 hours can grow mold, so readings matter more than how the surface feels.
Surface drying can make a room feel better while the wall and the sill stay wet. EPA guidance is to dry water-damaged areas and items within 24 to 48 hours, which is hard to meet on a wall you cannot see into. A moisture meter gives a reading that shows whether the cavity is dry, and thermal imaging can show a damp band before anything is opened.
Mold can trigger allergy and asthma symptoms in some people. EPA says sampling for mold is not usually recommended, so inspection and readings are the usual tools. A moldy area under about 10 square feet can often be cleaned by the homeowner, but larger areas, mold from sewage, and mold in the HVAC system call for professional help. The mold inspection page covers what an inspection includes.
Size, the materials that got wet, how long the water sat, and whether mold or a finished space is involved all move the job. No price is given here, because nobody can price it honestly before the wet area is seen. The price is confirmed on site before any work begins.
The first driver is how much wall and floor are wet, and whether seepage reached only the base of the wall or ran across the floor. A finished basement adds drywall, trim, carpet, pad and cabinetry, and the job grows if drywall has to be cut above the damp line. Plaster in an older house takes longer to dry than drywall does.
Access matters too: stairs only, a crawl space, a walk-out lower level, or a basement full of stored items all add time. Mold already present turns the work into a containment job. After-hours and weekend callouts also move the quote. Emergency-stage work, meaning extraction and drying setup, is explained and approved before it starts, and repairs after drying are quoted separately once someone has seen the wet area.
Your insurer decides coverage under your own policy, and the answer depends on the wording. Kansas Insurance Department guidance says most homeowners policies exclude flood and rising water. Ask your agent, in writing, how your policy treats water that enters through the foundation from the ground outside.
A standard homeowners policy generally responds to sudden and accidental water damage, such as a burst supply line. Water that comes in slowly through a foundation is a different question. Read your declarations page and any endorsements before you assume anything.
The crew can take photos, moisture readings and a description of the wet areas before anything is removed, and those records are useful to your insurer. Take your own photos before moving furniture, and call your insurer early. No one here can promise a payout. If you have a complaint about a claim, the Kansas Insurance Department consumer line is 1-800-432-2484.
Water tracks through a crack or a joint in the poured wall and shows as a damp line after heavy rain or thaw. In newer subdivisions the wall is often finished on the inside, so the damp shows first in the drywall above the base. The crew dries the base of the wall, the cavity and the finish above the damp line. Crack repair itself is separate work.
Water rises or runs along the slab edge where the wall meets the floor, often in a finished room where carpet and pad sit against the wall. Padding and carpet are usually the materials that hold moisture longest, so they are the first to come up. Readings at the joint show whether the water has reached the subfloor.
Pre-war houses in the Original Town core around Santa Fe Street often have block or stone cellars and, in many cases, no perimeter drain tile. Inner-ring houses from the 1940s and 1950s, such as those in Prairie Village, Roeland Park and Merriam, also have older block basements. Before disturbing materials in a pre-1980 house, check with KDHE and the EPA about lead paint and asbestos.
Farmhouses in Stilwell, Bucyrus, Clearview City and Hillsdale often have crawl spaces, and some walk-out lower levels have walls partly below grade. Access takes longer in these spaces, and drying there follows the crawl space work. On acreage, a basement that stays wet may be a septic or pump problem rather than surface seepage, and that is a different call.
Most post-1980 subdivisions in Olathe have poured full basements, usually finished, with perimeter drain tile and a sump pit. When seepage gets past that system, it tends to show along the wall-floor joint of a finished room, where the carpet and pad hold the moisture. A sump pit that runs constantly through a wet spell is a sign the surrounding soil is saturated.
In the inner ring and in the Original Town core, many cellars are older block or stone. Pre-war cellars often have no perimeter drain tile, so water has fewer ways out once it reaches the wall. Check older materials with KDHE and the EPA before disturbing them.
Indian Creek, Tomahawk Creek, Cedar Creek and Kill Creek all flooded hard in July and August 2017, and Indian Creek at State Line Road crested at about 28 feet. A house near mapped floodplain can have seepage after a long wet spell even if its basement never flooded. To check an address, use FEMA's Flood Map Service Center or the Kansas Division of Water Resources DFIRM viewer. The crew cannot tell you whether a property is in a flood zone.

Not always. A damp band can also come from condensation, a leak inside the wall, or a window well that overflows. Seepage usually shows after rain or thaw, leaves a line or crust at the base, and returns each wet season. A crew can take readings to sort out which it is.
EPA guidance says mold can grow on wood, drywall, carpet and furniture left wet for more than 24 hours. The goal is to dry water-damaged materials within 24 to 48 hours. If the wall has been wet for days, say so on the call, because that changes the drying plan.
Dry the space first, because wet materials keep getting worse while you decide. A restoration crew handles the water, the drying and the records for your insurer. Foundation waterproofing, grading and drain tile are separate contracts and are not offered here. Check any contractor you hire in Johnson County's contractor search before work starts.
On acreage, a basement that backs up or stays wet may be a failed septic field or an ejector pump problem rather than surface seepage. A crew can dry the space, but septic and pump repairs go to the right contractor. Phones are answered 24/7 at (833) 490-5225 if you want to talk through what you are seeing.
Not necessarily. Water moving through a narrow crack is common and does not always mean the wall is moving. Cracks that are wide, growing or offset should be looked at by a licensed structural engineer or a qualified contractor. The crew dries and documents the damage, but it does not assess the structure.
No. The crew dries the wall, floor and finished materials and gives you records for your insurer. Crack repair, drain tile and grading are separate work. Plumbing repairs need a licensed plumber, and in Johnson County that means a plumber licensed for work in the participating cities.
