Rerouting a dryer vent typically costs $200-$800, with an average near $450 for a short, accessible route using standard rigid metal duct. Longer runs, wall or ceiling work, difficult access, and roof exits can push the price above $1,000.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete reroute | $200 | $450 | $1,500+ | Higher quotes usually involve concealed routes or construction repairs |
| Added rigid duct | $10 per linear ft | $18 per linear ft | $30 per linear ft | Installed price varies with access and fittings |
| Exterior vent cap | $15 | $40 | $100 | Part only; specialty caps may cost more |
| Wall opening and patching | $75 | $200 | $500+ | Finishing and siding repairs can add expense |
What a standard dryer vent reroute typically costs
For a basic job, expect about $200-$500 to move the duct outlet a short distance through an accessible wall. A moderate reroute of 10-20 feet commonly runs $400-$900. Routes through a finished ceiling, attic, crawl space, or roof can cost $800-$1,500 or more.
Around $450 is a reasonable planning figure for a straightforward reroute, not a guaranteed flat rate. These estimates assume one residential dryer, ordinary access, standard 4-inch rigid metal duct, and no major framing or finish repairs.
Labor and local prices matter: urban markets and high-cost states may run 15%-30% above the ranges shown, while some rural markets may come in 10%-15% lower. A quote should specify route length, duct material, outlet location, and whether patching is included.
Assumptions: U.S. residential labor, standard materials, normal access, and no extensive electrical or structural work.
How duct, labor, and wall work shape the quote
Contractors may price the job as a package or separate out labor and materials. The ranges below describe common line items; not every project requires each one.
| Cost component | Typical price | What changes the charge |
|---|---|---|
| Labor | $75-$150 per hour | Access, crew size, and time spent routing duct |
| Rigid metal duct and fittings | $10-$30 per linear ft installed | Length, elbows, and concealed installation |
| Exterior cap and termination | $50-$200 installed | Wall, soffit, or roof exit and weatherproofing |
| Opening, patching, or siding repair | $75-$500+ | Wall type and finish quality required |
| Old duct removal and disposal | $25-$150 | Length, contamination, and access |
Labor and finish repairs often explain why two quotes for the same duct length differ substantially. Confirm whether the contractor includes cleanup, sealing, and testing airflow after installation.
Which duct length, elbows, and exit point raise the price
Route complexity can matter as much as total length. Each bend takes additional labor and can increase airflow resistance; some manufacturers and codes account for elbows by reducing the allowable equivalent duct length. The appliance installation instructions and local requirements should determine the permitted route.
Moving an outlet 3-6 feet through an accessible exterior wall may add only $100-$300 beyond a simple service visit. A 15-25-foot path with several turns can add $250-$700 or more. A new roof penetration often costs more than a wall exit because it requires roof flashing and careful weather sealing.
Ask for the proposed duct length and number of elbows in writing. Smooth-wall metal duct is generally preferred; flexible foil or plastic duct can create safety and code concerns and may not be allowed for concealed runs.
When do permits or exterior repairs affect dryer vent pricing?
Small, like-for-like vent changes may not require a permit, but rules vary by city and project scope. New roof penetrations, work affecting fire-rated assemblies, or changes tied to broader remodeling may trigger permit or inspection requirements. Check with the local building department before work begins.
Permit and inspection charges, where required, can add roughly $50-$300. Siding, stucco, brick, or roofing repairs may add $100-$600 depending on material and how closely the finish must match. Pest screens should not obstruct airflow; some vent caps with fine mesh can collect lint.
Separate the vent installation price from permit and finish-repair allowances. That makes it easier to compare bids and identify costs that may be billed later.
How many hours does a dryer vent reroute take
A simple reroute through an accessible wall often takes 2-4 hours for one technician. A longer route through an attic or crawl space may take 4-8 hours, while roof work or opening and repairing finished surfaces can extend the job to a full day or require a separate trade.
Some contractors charge a minimum service fee of $100-$200, even when the actual work is brief. A second worker may be needed for roof access, long duct sections, or safe handling in tight spaces, increasing labor charges.
Request an estimated crew size and billable hours alongside the flat price. A low hourly rate is not necessarily the lowest total if the route requires extra setup or multiple visits.
Why attic, crawl-space, and roof routes cost more
An exposed basement or garage route is generally less expensive than a concealed path because the installer can reach the duct without removing finished surfaces. Attic work may require crawling over insulation and cutting a new opening; crawl spaces can be damp, cramped, or difficult to access.
For a similar duct length, restricted attic or crawl-space access may add $150-$500. A roof exit can add another $200-$600 for penetration, flashing, and safe roof work, with steeper or higher roofs sometimes costing more. Repairing drywall or ceilings after installation is usually a separate charge.
Choosing the shortest compliant route through accessible space is often the biggest controllable cost reduction. The route still needs to meet the dryer maker’s instructions and local code.
Three sample quotes for common reroute jobs
| Job and scope | Estimated labor | Likely total |
|---|---|---|
| Move outlet 5 ft through accessible exterior wall; rigid duct and basic cap | 2-3 hours | $250-$450 |
| Install 15 ft route through a crawl space; three elbows and wall termination | 4-6 hours | $500-$900 |
| Run 25 ft through attic to a new roof cap; patch interior opening | 6-10 hours | $1,000-$1,800 |
These examples assume ordinary residential access and standard materials. The roof example includes more labor and weatherproofing; extensive drywall, siding, or roofing repairs could raise the final bill.
How to lower the rerouting price without compromising airflow
Keep the route short and avoid unnecessary turns, while staying within the appliance maker’s allowed length and local requirements. Before requesting bids, clear stored items from the work area and identify the current duct path, outlet location, and any known wall or roof obstacles.
Compare at least two itemized quotes on the same scope. Check whether each includes rigid duct, a suitable exterior termination, removal of old materials, sealing, cleanup, and airflow testing. Bundling vent work with other planned exterior or laundry-room repairs may reduce repeat trip charges.
Do not cut cost by accepting an undersized, crushed, or unsuitable duct. If the existing route can be cleaned and corrected safely, ask whether repair is an option; replacement or rerouting is more appropriate when the path is damaged, excessively long, or cannot meet installation requirements.
