After water intrusion, residual moisture hides in subfloors, wall cavities, and insulation. Our crews use commercial-grade refrigerant and desiccant units sized to the affected square footage, pulling moisture down to manufacturer-specified drying goals while monitoring with thermo-hygrometers. In Spokane homes this often means treating older plaster-and-lath construction that holds water longer than modern drywall, requiring slower, controlled extraction to avoid cracking.
Edge cases we see regularly include crawl spaces under 101 E Hastings Rd properties where poor ventilation lets humidity spike after pipe bursts, and multi-story structures where water migrates downward through joist bays. We isolate affected zones with containment barriers and run negative air to keep spores from spreading to unaffected rooms. Daily moisture logs are kept so homeowners can see progress before we release the space.
Code considerations in the Spokane area include ensuring dehumidifiers are properly grounded on GFCI circuits when used near standing water, and confirming that exhaust air from desiccant units does not create pressure imbalances that pull combustion gases from appliances. We never leave equipment running unattended overnight without remote sensors that alert our on-call technician if power or performance drops.
Dehumidification Services We Offer
✓Crawl Space Dehumidification
Install and monitor commercial units in crawl spaces to dry saturated soil and joists after leaks, keeping mold from forming on wood framing.
✓Basement Wall Drying
Place low-grain refrigerant dehumidifiers against foundation walls to pull trapped moisture from concrete and reduce efflorescence risk.
✓Attic Moisture Extraction
Deploy desiccant dehumidifiers in attics to remove condensation and insulation saturation following roof or ice-dam leaks common in Spokane winters.
✓Hardwood Floor Dehumidification
Use targeted airflow and dehumidification under and around hardwood to prevent cupping and delamination after surface water events.
✓Commercial Space Drying
Scale multiple high-capacity units for offices and retail spaces to meet insurance drying standards without extended business interruption.

How it works
- 1
Moisture Mapping
Technicians use meters to locate all wet materials and determine equipment placement needs.
- 2
Equipment Setup
Units are positioned, containment is installed, and initial humidity readings are recorded.
- 3
Daily Monitoring
Readings are taken each visit; equipment is adjusted or rotated until target moisture levels are reached.
- 4
Final Verification
Independent moisture checks confirm all materials are dry before equipment removal and site release.
Pricing
Pricing depends on affected area size, equipment runtime, and number of units required. Upfront quotes provided after on-site assessment.
