Nashville’s muggy summers and wet winters push moisture straight into vented crawl spaces. When humidity rises above 60 %, the result is moldy sub-flooring, musty odors, and higher energy bills. Installing a dedicated crawl space dehumidifier fixes the problem, but what does it actually cost? CountBricks analyzed thousands of local projects to bring you the clearest answer—then built an AI engine that can quote your exact price while you talk. Below we break down every factor influencing crawl space dehumidifier installation cost and show how CountBricks keeps residential projects on budget.
• Unit capacity and efficiency rating (70-pint vs 100-pint, Energy Star vs standard)
• Square footage and moisture load in the crawl space
• Existing electrical service and need for a new GFCI receptacle
• Drainage method: gravity line, condensate pump, or tie-in to sump
• Encapsulation upgrades: vapor barrier, insulation, air sealing
• Access constraints—low clearance, tight entry hatch, debris removal
• Local permit fees and inspection requirements
Across recent CountBricks projects, a stand-alone crawl space dehumidifier install—including labor, mid-grade 70-pint unit, electrical tie-in, and basic drain—lands between $2,200 and $3,400. Full encapsulation with a high-capacity, Wi-Fi-enabled unit can climb to $4,500–$6,800. These numbers reflect turnkey service by licensed subcontractors and materials priced through CountBricks’ real-time supplier database.

• Dehumidifier unit: $900–$1,800 depending on capacity and smart controls
• 10-mil polyethylene vapor barrier (optional): $0.35–$0.55 per sq ft
• Electrical supplies: GFCI outlet, 12-gauge cable, breaker—$120–$220
• Condensate pump and tubing (if needed): $140–$260
• Miscellaneous fasteners, hangers, and sealant: $65–$110
CountBricks’ regional labor averages $68–$75 per hour for a licensed residential electrician and $45–$55 for a weatherization crew. Typical installs require:
• 1–2 hours site prep and debris clearing
• 2–3 hours electrical rough-in and outlet installation
• 1–2 hours unit placement, hanging straps, and drainage routing
• 2–4 hours vapor barrier or insulation work (if selected)
• Temporary dehumidifier rental while waiting for parts can add $30-$40 per day—CountBricks coordinates suppliers to avoid delays.
• Ignoring encapsulation may seem cheaper now, but our data shows 27 % higher energy bills over five years without it.
• Smart dehumidifiers integrate with HVAC and qualify for local utility rebates—CountBricks auto-flags incentives inside your estimate.
Homeowners sometimes attempt a DIY crawl space install to cut labor. Yet mistakes—undersized unit, poor drainage, or code violations—regularly lead to double spending. With CountBricks, professionals arrive with exact material lists and code-compliant task checklists, ensuring first-time success and transferable warranties.

The Greene family’s 1940s bungalow sat over a 24-inch crawl space with standing water after every rain. Mold spots appeared on hardwoods, and utility bills spiked. They opened the CountBricks app, narrated room sizes, and uploaded a smartphone scan of the crawl area. Within four minutes, CountBricks delivered a $3,870 proposal: 90-pint Energy-Star dehumidifier, full 12-mil vapor barrier, dedicated GFCI, and condensate pump to the existing sump.
1. Day 1 – Material drop and debris removal
2. Day 2 – Electrical rough-in and vapor barrier install
3. Day 3 – Dehumidifier hang, pump line, final inspection
• Humidity fell from 78 % to 34 % average within 48 hours
• Odor complaints disappeared immediately
• Utility usage dropped by 18 % over the next billing cycle
• Home appraisal increased by $9,500 thanks to documented encapsulation
• Specify a unit with remote humidity alerts—early warnings prevent overflow incidents.
• Run a dedicated 20-amp circuit; shared outlets are the number-one cause of nuisance shut-offs.
• Seal sub-floor penetrations before laying vapor barrier to lock out ground-source radon.
