Few residential upgrades deliver a bigger return on comfort than a quiet, code-compliant bathroom vent. Excess moisture breeds mold, peels paint, and shortens the life of finishes. A high-performance fan paired with an airtight duct quickly removes steam, eliminates odors, and protects your home’s structure. CountBricks specialists include ventilation on every remodel checklist because a healthy home starts with dry surfaces.
CountBricks tracks real-time labor rates and material pricing across hundreds of ZIP codes. For a typical single-family home, the total cost to install bathroom vent currently ranges from $465 to $1,050. Most projects fall near $720, including fan, duct, exterior hood, labor, and permit. Your exact number is calculated in seconds by our voice-to-quote engine, but the breakdown below shows where the money goes.
• Mid-range 80–120 CFM ENERGY STAR fan: $140–$240
• Insulated 4-inch rigid or flex duct (10–15 ft): $45–$80
• Exterior wall or roof cap with backdraft damper: $35–$60
• Electrical cable, connector, and switch upgrade: $25–$45
• Misc. fasteners, sealants, vapor barrier tape: $15–$30
• Electrician (1.5–3 hrs) at $85–$120/hr: $130–$360
• Carpenter/Roofer for duct run and cap (1–2 hrs): $90–$180
• Disposal, site protection, and clean-up: $25–$60
• Attic access vs. first-floor ceiling: harder access means more hours
• Distance to exterior wall or roof: longer duct runs add material and time
• Existing wiring capacity: an older circuit may need a new home run
• Fan features: humidity sensor and LED light increase unit cost
• Local permitting requirements: some jurisdictions require inspection fees

A seasoned DIYer may swap a fan for $250 in parts, but new ductwork and wiring cross multiple trades. The risk of cutting a structural joist or venting moist air into an attic can dwarf any savings. CountBricks crews are licensed, insured, and follow International Residential Code guidelines on every installation.

A recent project highlights how our platform refines the cost to install bathroom vent in real time. The homeowner lived in a 120-year-old brownstone with no attic and thick masonry walls. Traditional contractors quoted “somewhere between $1,200 and $1,800” because of the unknowns. During a five-minute CountBricks call, we gathered dimensions, ceiling height, and available electrical circuits.
• Materials: $268 for a 90 CFM low-profile fan, 4-inch rigid duct, and stainless wall cap
• Labor: $582 based on 4.8 technician hours at current Boston wage tables
• Permit & inspection: $75 auto-pulled from municipal database
Total: $925, emailed instantly with a detailed scope and timeline.
1. Core-drilled a 4-inch hole through brick in 28 minutes—AI had allocated 30, confirming accuracy
2. Installed a humidity-sensing fan that now runs only when moisture spikes, cutting energy use by 42%
3. Provided a digital airflow report for the condo association via CountBricks.com/portfolio
“The price was dead-on and the job wrapped before lunch. My mirrors stay clear, and I didn’t have to chase down three different trades.”
• Choose fans rated for continuous operation to prevent mildew in tight urban bathrooms
