About Structural Cavity Drying System
Standard air movers blow air across room surfaces, doing little to dry water trapped inside insulated walls, ceiling cavities, and under multi-layer floor systems in San Francisco, California. Our specialized structural cavity drying systems solve this challenge through engineered positive and negative airflow. Using precision manifolds connected to flexible delivery tubes, we deliver dry, warm air directly into enclosed wall voids and joist bays. This targeted pressure differential forces moisture out through small relief ports, drying structural assemblies in place and preventing costly demolition.
Common Problems We Solve With Structural Cavity Drying System
Enclosed Wall Voids
Wet framing hidden behind painted sheetrock and tile.
Multi-Layer Floor Dampness
Water trapped between hardwood and subflooring layers.

Manifold Tubing Hookup

A storm flooded our finished basement with three inches of muddy water. Their team pumped out the pooling water, removed saturated carpet padding, and set up five commercial dehumidifiers. The daily moisture logs gave our insurance adjuster exactly what was needed to approve our claim.

When our commercial fire sprinkler head went off by mistake in our office suite, black pipe water soaked eight cubicles. Their technicians staged containment barriers, extracted water from the carpet tiles, and ran quiet desiccant units so our team was back working two days later.
