Dehumidification Cost Calculator
Dehumidification is the moisture-removal half of structural drying, using LGR or desiccant dehumidifiers to pull water vapor from the air so materials can release their moisture. This calculator estimates dehumidification cost by area and days, adjusted for your region.

Cost Snapshot
Average dehumidification cost in 2026
Based on a typical 500 sq ft category 1 — clean water job at the national baseline. The calculator above personalizes these figures to your state and situation.
Minimum

Per sq ft
$1.00–$4.00
Professional dehumidification typically costs $500 – $2,500, averaging about $1,200 for a 500 sq ft single-family home with category 1 — clean water. That works out to roughly $1.00–$4.00 per square foot, with most projects completing in 3–8 days. This type of loss is often covered by a standard homeowners policy — typically around 85% after your deductible.

- Inspection & assessment
- Emergency 24/7 response
- Standing-water extraction
- Structural drying
- Drying equipment rental
- Cleaning & sanitizing
- Disposal & hauling
Not typically part of this service: demolition & tear-out, material replacement, mold treatment.
Biggest cost drivers
For dehumidification, structural drying, drying equipment rental carry the most weight in the total — which is why area and water category move the price the most.

How this calculator works
Unlike simple square-foot estimators, this calculator builds your total from individual cost components — inspection, water extraction, structural drying, equipment rental, demolition, material replacement, cleaning and skilled labor. Each component is priced from a researched 2026 national baseline, then adjusted by your state's cost index and labor market, the water category, and whether emergency service or mold remediation is required.
What affects your cost the most
- Affected area & rooms: more square footage means more extraction, drying and materials.
- Water category: gray and black water require far more sanitizing and disposal.
- Materials involved: replacing hardwood, cabinets or subfloor costs far more than drying drywall.
- Regional labor rates: skilled restoration labor varies by more than 50% across states.
- Emergency service: after-hours dispatch adds a labor premium.
- Mold remediation: containment and treatment add significant cost when present.
Labor costs
Professional restoration labor runs about $55/hour at the national baseline, before regional adjustment. Typical crews of two work through extraction, tear-out, drying setup and cleaning, with reconstruction billed separately when rebuilding is required.
