Homeowners across the country lose thousands every year to moisture-driven damage beneath their floors. Mold, wood rot, and unhealthy indoor air all begin in damp crawl spaces. At CountBricks, we field daily questions about the true cost to install a dehumidifier in a crawl space for residential projects. This guide breaks down every factor so you can budget accurately and protect your home’s value.
Because CountBricks pulls live material and labor data from suppliers nationwide, we see typical all-in pricing fall between $1,800 and $3,500 for most single-family homes. That figure includes equipment, electrical hookups, vapor barrier touch-ups, and professional installation labor. High-capacity units, tight access, or severe moisture remediation can push totals up to $5,000, while straightforward installs in newer homes may land closer to $1,500.
• Unit capacity (pints per day) directly impacts purchase price
• Existing crawl space height and access dictate labor time
• Electrical upgrades may be required for dedicated circuits
• Geographic humidity and local code requirements influence sizing
• Add-ons like drainage pumps or smart monitors increase material cost
CountBricks recommends ENERGY STAR® rated, low-temperature dehumidifiers designed for crawl spaces. Expect $800–$1,600 for a 70–120 pint unit. Built-in digital controls and defrost cycles add upfront cost but reduce lifetime operating expenses.
Our verified residential crews typically need three to six labor hours depending on clearance and duct routing. CountBricks’ AI scheduler monitors regional wage rates, averaging $65–$85 per hour for licensed installers.
Most units require a dedicated 120-volt GFCI outlet. If one is not present, CountBricks electricians can add a new circuit, usually $250–$450 including permit filing.
A dehumidifier is only part of the solution. Proper encapsulation and drainage extend unit life and performance. CountBricks crews can integrate:
• 6-mil to 20-mil vapor barriers ($0.50–$1.50 per sq. ft.)
• Perimeter French drains ($25–$35 per linear foot)
• Sump pump installations ($800–$1,200)
Traditional estimating relies on manual takeoffs and static price books. CountBricks replaces guesswork with real-time intelligence:
• Voice-activated scope capture lets you describe the crawl space while onsite
• AI parses blueprints to calculate square footage, linear footage, and clearance instantly
• Cloud pricing pulls today’s distributor quotes for equipment and materials
• Regional labor benchmarks adjust automatically to your zip code
The result is a line-item estimate you can trust—delivered to your inbox before you leave the property.

The cost to install dehumidifier in crawl space may appear steep, but consider the alternative:
• Average crawl space mold remediation: $3,000–$7,000
• Subfloor replacement: $10,000+
• HVAC efficiency loss from damp air: up to 15% higher energy bills annually
Our customers typically see payback within three to five years through avoided repairs and lower utility expenses.
All crawl space dehumidifiers installed by CountBricks include a five-year equipment warranty and a one-year labor guarantee. Our AI monitoring option sends alerts if humidity creeps above your chosen threshold, so minor issues never become major headaches.

When the Martins purchased their 1940s Brookside bungalow, a musty odor greeted them at the door. A CountBricks inspector found crawl space humidity hovering at 78%, with early signs of joist mold. Using our AI blueprint reader, the project manager generated a precise 1,020 sq. ft. takeoff and projected the cost to install dehumidifier in crawl space at $2,640.
• 90-pint ENERGY STAR® dehumidifier with smart humidity monitor
• 14-mil reinforced vapor barrier across entire footprint
• New 20-amp GFCI circuit and sealed condensate line to exterior
• Completion time: 6 hours door-to-door
• Final invoice matched the AI estimate within 1.2% variance
Post-installation readings stabilized at 48% relative humidity. Six months later, an HVAC energy audit showed a 12% decrease in cooling costs. The Martins credited the transparent CountBricks process for removing “budget angst” and preventing hidden overages.
• Choose a unit rated for low temperatures if winters dip below 50°F
• Pair dehumidification with airtight vents to keep exterior moisture out
• Replace filters quarterly; CountBricks offers an auto-ship program
• Monitor humidity remotely with our optional Wi-Fi module for peace of mind
• Schedule an annual crawl space inspection to catch drainage issues early
