About Sub-Surface Cavity Drying
When water seeps beneath built-in kitchen cabinets, shower bases, or between multi-layer subflooring in San Marcos, Texas, standard surface air movers cannot evaporate the hidden moisture. Leaving water trapped in these interstitial voids causes structural dry rot and black mold. We use specialized sub-surface drying injectors, vacuum manifolds, and flex-ducting to force warm dry air directly into hidden structural cavities without destructive demolition.
Common Problems We Solve With Sub-Surface Cavity Drying
Inaccessible Shower Base Voids
Water leaks beneath fiberglass shower stalls, rotting subflooring out of sight.
Sill Plate Moisture Damming
Water trapped behind vapor barriers cannot evaporate without direct air injection.
How Our Sub-Surface Cavity Drying Process Works
Borescope Cavity Inspection
Miniature cameras inspect sub-surface voids for standing water in San Marcos, Texas.
Precision Micro-Port Ducting
We connect high-pressure air manifolds to small 3/8-inch hidden injection holes.
Positive Pressure Cavity Airflow
Heated dehumidified air is pumped through voids, exhausting moisture vapor.
Benefits of Professional Sub-Surface Cavity Drying
Zero Destructive Demolition
Avoids tearing out expensive tiled shower pans, cabinets, and subfloors.
Eliminates Hidden Mold Voids
Dries dark, unventilated cavities before mold colonies can establish.
Saves Thousands in Rebuild Costs
In-place cavity drying costs a fraction of full kitchen and bathroom remodels.
Sub-Surface Cavity Drying Pricing Factors
Number of Cavity Zones
Count of independent cabinet bases, shower pans, and subfloor voids treated.
Cavity Insulation Density
Dense exterior wall insulation requires higher air injection pressure.
Drying Run Time
Days required to achieve verified moisture equilibrium inside structural voids.
Sub-Surface Cavity Drying Questions
How do you dry water trapped under my shower pan in San Marcos, Texas?
We use precision cavity injection systems to blow high-velocity dry air through small access ports into the void under the pan. Call (800) 692-7103.
Will sub-surface cavity drying damage my baseboards?
No, we carefully remove baseboards, drill small holes that baseboards will cover upon reinstallation, and reattach them cleanly.
How do you know when the hidden cavity is dry?
We insert specialized deep-wall moisture probes into the cavity to verify wood moisture content is below 12%.
