Structural Drying & Dehumidification in Saint Paul, MN
Commercial dehumidifiers and air movers remove moisture from the structure, with daily readings logged from the material itself for claim documentation. Structural drying brings building materials back to a documented dry standard using air movers and dehumidifiers rather than surface evaporation alone. Moisture readings are logged through the process so the substrate, not just the surface, is confirmed dry before anything is rebuilt.
Frequently asked questions
What does building on sandstone change about a wet basement?
It changes how concentrated water behaves. St. Peter sandstone is weakly cemented and erodes when flow is aimed at it, so a downspout or a broken lateral discharging against the bluff face can undercut material rather than simply wetting it. Diffuse seepage is a drainage job; a concentrated stream is an erosion job. Carry roof water well past the wall before anyone treats the inside face as the whole repair.
Why does the cellar flood at snowmelt rather than during a June storm?
Because winter prepares the openings. Deep frost widens joints and cracks over several months, and the melt then delivers a large volume into paths that were smaller before the freeze. June rain meets a wall that has not just spent a season being worked open. Extraction after melt is often a short, high-volume event against the uphill wall, not a slow summer seep.
The house sits above the river. Shouldn't the slope drain the water away?
For surface water on the downhill side, yes. For the uphill wall, no. Slope carries rain away from the low side but sends subsurface water toward whatever is cut into the hill. On a bluff lot the uphill foundation is a retaining wall, and it is usually the first to show standing water. Perimeter drainage at that cut matters more than the view of the river.
