Foundation repair & crawl space encapsulation in St. Marys
In St. Marys the groundwater is the story. The river is tidal, the banks are low, and the water table sits close enough to the surface that crawl spaces here rarely dry out on their own. Drainage first, then sealing - in that order - is what actually holds.
Local conditions
What we see under St. Marys homes
The old town sits right on the St. Marys River where it runs tidal, on low sandy bank soil with marsh and creek drainage threading through the neighborhoods. Groundwater is shallow year-round and it moves with the tide and the rain, so a crawl space that is merely damp in March can hold standing water in September. Piers and footings set in soil that saturates and drains repeatedly lose bearing gradually rather than all at once.
That shows up as soft, punky band joists and sill plates, rusted pier straps and jack posts, mold on the underside of the subfloor, and a smell that rises into the house on humid mornings. River-valley fog and heavy dew keep vented spaces wet even through weeks without rain, which is why homeowners here so often tell us the crawl space is wet when it has not rained in days.
A vapor barrier laid over wet dirt does nothing in these conditions. We install interior drainage and a sump to move groundwater out first, then seal the floor and walls, close the vents and add dehumidification so the space stays in range. Structural work - new steel supports, supplemental beams, or piers where a footing has genuinely dropped - goes in after the water is handled, not before.

“Our floors had gotten soft and the whole downstairs smelled musty. They inspected the crawl space, showed us photos of the rot and moisture, and fully encapsulated it. The smell is gone, the floors feel solid, and our humidity finally stays under control.”

Common questions in St. Marys
Foundation & crawl space questions from St. Marys homeowners
My St. Marys crawl space floods some seasons, can you fix it?
Yes. Near the tidal river the water table is shallow and moves with the tide, so we install interior drainage and a sump to move the water out first, then seal the space.
Why is the wood under my house rotting?
Shallow groundwater keeps the framing damp, which rots band joists, sills and posts over time. We dry the space and repair the framing that has already gone soft.
Is the inspection free?
Yes, with no obligation. You get moisture readings, a structural check, photos and a written report with fixed pricing.
Do you work near the historic waterfront?
Yes, we work throughout St. Marys, including the older homes near the river where groundwater sits close to the surface.
Do I need drainage or just a vapor barrier here?
On this ground you usually need drainage first. A barrier over wet dirt traps the water, so we move it out with a drain system and sump, then seal over ground that stays dry.
