Groundwater & Basement Water Intrusion in Lanham, MD
Basement seepage, failed sumps and water through the slab are extracted and dried, and the path from the ground is found so the floor stays dry next season. The path from the ground is named first: through the wall, up through the slab, back through a drain, or from a sump that stopped. The space is extracted and dried, with the porous materials the water touched removed, and the delivery is addressed, because a dried floor only stays dry if the water stops arriving.

Often needed alongside
- Structural Drying & Dehumidification
Sealed air movers and dehumidifiers bring framing, subfloor and drywall back to a measured dry standard, with daily readings logged from inside the material.
- Emergency Water Extraction
Standing water is pumped and extracted around the clock, before it climbs the walls and soaks the subfloor. Same-day response where coverage allows.
- Mold Inspection & Testing
An independent assessor confirms whether the assembly that got wet is actually dry, whether growth started while it was not, and how far it reaches.
Frequently asked questions
What is the gray clay layer?
A specific clay bed that runs under this part of the county, well known to anyone who builds here. What makes it notable is not that it is clay but that it becomes very slick when saturated, so ground above it can slide along the top of it.
Is this the same as expansive clay?
No, and the distinction matters. Expansive clay swells and shrinks in place and lifts what is on it. This slides, so the movement is lateral along a plane, which produces walls out of plumb and floors out of square rather than heave.
Does managing water actually help?
It is the main thing available. The layer only moves when it is wet, so keeping surface and roof water off the slope above a house reduces what reaches it. That does not stop the geology, but it changes how often it is triggered.
