Dryer duct replacement typically costs $150-$600, with a national average near $325 for a standard home installation. The price depends mainly on duct length, material, access, labor, and whether the route must be changed or extended.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Standard replacement | $150 | $325 | $600 | Existing route, accessible connection |
| New or rerouted duct | $300 | $700 | $1,500 | Longer path or wall and ceiling work |
| Duct material | $1.50/ft | $3/ft | $6/ft | Rigid metal; material and diameter affect price |
What a standard dryer duct replacement costs
For a straightforward replacement, homeowners commonly pay $150-$600, including a short run of duct, basic connections, and labor. A simple job may involve removing damaged or flexible duct and fitting code-compliant rigid metal duct in its place. The average estimate of about $325 assumes normal access and no significant wall, roof, or exterior repairs.
Longer duct runs, concealed routes, or a new exterior termination can push the total to $600-$1,500 or more. Quotes vary by market and job scope, so confirm whether the estimate includes removal, a new vent cap, sealing, and cleanup. For a standard, accessible route, $250-$450 is a practical budget range.
Assumptions: U.S. national pricing, standard residential dryer, ordinary access, and no major framing or finish repairs.
How duct, labor, and vent-cap charges add up
Contractors may quote one installed price or list materials and tasks separately. The table shows common allowances; actual totals depend on route length, local labor rates, and whether access panels or finishes need work.
| Quote item | Low | Typical | High | What changes the charge |
|---|---|---|---|---|
| Rigid metal duct | $1.50/ft | $3/ft | $6/ft | Diameter, gauge, and fittings |
| Labor | $100 | $225 | $500 | Access and time on site |
| Exterior vent cap | $15 | $35 | $90 | Basic hood versus pest-resistant model |
| Removal and disposal | $25 | $60 | $150 | Old duct location and condition |
| Wall or ceiling access repair | $50 | $175 | $500 | Opening size and finish restoration |
Labor is often billed as part of a minimum service charge rather than by the hour. When quoted hourly, rates commonly fall around $75-$150 per hour, with a separate service or trip fee of $50-$125 possible. Ask whether the quoted labor includes testing airflow and sealing joints.
Materials are often a smaller share of the bill than access, removal, and installation time.
Route length and duct material change the estimate
A short, straight route is generally less costly than a long path with elbows or hidden sections. Many residential installations use 4-inch duct, but the permitted route length depends on the dryer maker’s instructions and the number of bends. Added elbows can reduce the allowable equivalent length; a contractor should check the appliance specifications instead of assuming one universal limit.
Rigid galvanized steel or aluminum duct usually costs more to install than flexible material but provides a smooth interior and is commonly preferred for concealed dryer runs. Semi-rigid connectors are often used for the short connection behind the appliance; plastic or foil accordion duct can trap lint and may not meet local requirements for the installation. Extra length, multiple turns, and concealed access can matter more than the per-foot material price.
A route of 8-12 feet with one or two bends may remain near the standard replacement range if accessible. A 20-30-foot route, several elbows, or a roof exit can add $150-$600 or more, especially when the path needs redesign or access openings.
Regional prices vary with labor and access
In lower-cost rural and Midwestern markets, a basic replacement may run about 10%-15% below the national average. Large metropolitan areas in the Northeast, West Coast, and parts of Alaska or Hawaii may be 15%-35% higher because of labor rates, travel, and business overhead. These are broad comparisons, not fixed regional tariffs.
Local housing also changes the scope. A basement laundry room with an exposed duct may be inexpensive to service, while a second-floor dryer vent routed through a finished ceiling can require more labor. Compare local quotes using the same duct length, material, access assumptions, and included repairs.
Installation time affects the labor charge
A technician may finish an accessible like-for-like replacement in 1-2 hours. A reroute, roof termination, or difficult crawlspace or attic route can take 3-6 hours or require a second worker. Scheduling may also affect the bill if the job is urgent or requires a specialty roofer, electrician, or drywall repairer.
Ask the contractor to specify crew size, estimated hours, and the hourly or flat-rate charge. A low labor estimate may exclude testing, hauling away the old duct, or repair work. Written scope is the best way to compare labor charges fairly.
Removal, roof exits, and repairs add to the bill
Removing old duct may cost $25-$150 when it is accessible; removal can cost more if it is buried behind finished surfaces. A new wall or roof termination may add $75-$300 for the cap and installation, before significant roof or siding repairs. Opening and patching drywall can add roughly $50-$500 depending on the opening and finish.
Cleaning lint from the existing route is sometimes offered for $100-$250, but it is not the same as replacing damaged duct. A contractor should identify whether the duct is crushed, disconnected, excessively long, or simply dirty. Request separate prices for replacement, cleaning, and finish repairs so optional work is clear.
Repairing a connection costs less than rerouting
If only the short connector behind the dryer is damaged, replacing it may cost about $75-$200, including basic labor. Reconnecting a loose joint or replacing a vent hood can also cost less than a full duct run when the main route is intact, properly sized, and accessible. A full replacement is more appropriate when duct is crushed, corroded, poorly routed, or made from unsuitable material.
Three common estimates illustrate the difference: a 6-foot accessible replacement with rigid metal duct may total $200-$350; a 15-foot run with two elbows and a new wall cap may cost $350-$700; and a 25-foot concealed reroute with access and patching may reach $800-$1,500. Choose the least extensive work that restores a safe, manufacturer-compliant route.
Lower the replacement price by controlling the route
Keep the existing route when it meets the dryer manufacturer’s requirements and is in good condition. Avoid adding unnecessary length or bends, and ask whether an accessible wall termination can replace a more complicated roof route. Moving the dryer or doing demolition without a plan can create extra work rather than savings.
Get two or three itemized estimates that state duct type, diameter, length, number of elbows, vent-cap work, removal, testing, and repairs. Ask whether a service minimum or disposal fee applies. Comparing identical scopes and leaving cosmetic upgrades out of the quote helps keep the price focused on the duct replacement.
