Contractor Quote Checklist
Dryer Vent Replacement And Cleaning Quote Checklist Before Approval
Short answer: approve a dryer vent replacement or cleaning quote only after it states the duct material, duct route, exterior termination, lint removal method, airflow verification, gas dryer safety scope, wall repair, cleanup, and warranty terms.
Dryer vent work is easy to underestimate because the visible part may be only a short hose behind the dryer. The actual risk is hidden in the wall, crawlspace, attic, roof route, or exterior hood.
USFA dryer fire guidance warns that lint buildup and poor cleaning raise fire risk. CPSC says longer drying times or damp clothes after a normal cycle can point to a blocked lint screen or exhaust duct. Those warnings make the quote details important before you approve the work.
Start With The Complaint
The contractor should write what problem triggered the estimate: long drying cycles, hot laundry room, burning smell, visible lint, damaged transition duct, disconnected vent, bird nest at the hood, crushed duct behind the dryer, or a dryer error code.
A cleaning-only quote can be reasonable when the duct is sound. A replacement quote is more appropriate when the duct is plastic, foil, crushed, loose, too long, routed poorly, or terminating somewhere other than outdoors.
Confirm Duct Material
The Department of Energy clothes dryer vent job aid calls for rigid or semi-rigid metal duct, short and straight routing, outdoor termination, and no fasteners that penetrate the duct. BASC guidance also points to smooth metal duct and exterior venting for ducted dryers.
The quote should say whether the old transition duct, in-wall duct, attic duct, or exterior run will be replaced. If only the flexible hose behind the dryer is included, the estimate should say that clearly.
Require Exterior Termination Details
The quote should identify the termination point: wall hood, roof cap, crawlspace wall, garage wall, or another exterior outlet. It should say whether the exterior flap opens during operation, whether the hood has a backdraft damper, and whether screens or cages that trap lint will be removed or corrected.
Do not approve a quote that leaves the dryer exhausting into an attic, crawlspace, garage, wall cavity, or indoor utility room.
Separate Cleaning From Replacement
A good quote separates lint removal from duct replacement. Cleaning should describe the access points, brush or vacuum method, dryer pull-out, transition duct cleaning, wall duct cleaning, exterior hood cleaning, and debris removal.
Replacement should describe duct diameter, material, elbows, clamps, foil tape or approved connections, wall or ceiling access, patching, and whether old duct disposal is included.
Ask For Airflow Verification
CPSC recommends checking the outside vent while the dryer operates to confirm exhaust air is escaping. Your quote should include a before-and-after airflow check, exterior flap observation, or another written verification step.
If the contractor cannot verify airflow after cleaning, ask what hidden restriction remains and what it will cost to access it.
Handle Gas Dryer Safety Separately
If the dryer uses gas, the quote should say who moves the appliance, who reconnects it, and whether the gas line and connection will be inspected. USFA guidance advises professional service for gas dryers to make sure the gas line and connection are intact and free of leaks.
Do not assume dryer vent cleaning includes gas appliance service unless it is written.
Dryer Vent Quote Review Table
| Quote area | What to confirm | Why it matters |
|---|---|---|
| Problem | Long drying time, heat, lint, odor, blocked hood | The service should match the symptom. |
| Duct material | Rigid or semi-rigid metal, diameter, elbows, clamps | Poor duct material can trap lint and restrict airflow. |
| Route | Short, straight path to the outdoors where possible | Long or crushed routes reduce performance. |
| Cleaning | Brush, vacuum, dryer pull-out, exterior hood cleanup | Lint can remain in several parts of the system. |
| Verification | Airflow check, flap movement, final operation test | The finished system should actually exhaust outside. |
Questions To Ask Before Approval
- Is this a cleaning-only quote, a replacement quote, or both?
- What duct material and diameter are included?
- Will the dryer vent directly outdoors?
- Will screws or fasteners penetrate the duct interior?
- Will the exterior flap be cleaned and tested?
- Will you pull out the dryer and clean the transition duct?
- How will airflow be verified after the job?
- Who handles gas dryer disconnection, reconnection, or leak concerns?
- Are drywall, siding, roof, or crawlspace access repairs included?
Red Flags In A Dryer Vent Estimate
- The quote promises cleaning but does not say how the full duct path will be reached.
- The contractor plans to leave plastic or foil duct in place without explaining why.
- The duct terminates indoors or in an attic, garage, crawlspace, or wall cavity.
- No airflow check is included after service.
- The quote ignores gas dryer handling while requiring the appliance to be moved.
- Wall, ceiling, roof, or siding repair is excluded but not priced separately.
Quote check: dryer vent work is not just lint removal. The finished system should use the right duct material, exhaust outdoors, avoid lint-trapping fasteners, and prove airflow after the work.

FAQ
Should a dryer vent quote include airflow testing?
Yes. At minimum, ask for a final check that the exterior vent is moving air while the dryer runs.
Is flexible foil duct acceptable?
Ask the contractor to cite the appliance instructions and local requirements. DOE and BASC guidance favor smooth rigid or semi-rigid metal duct for dryer exhaust.
How often should a dryer vent be cleaned?
USFA and CPSC focus on cleaning lint filters, dryer areas, and exhaust paths, especially when drying times get longer. Homes with pets, long ducts, or heavy laundry loads may need more frequent service.
Does dryer vent cleaning include gas dryer service?
Not automatically. If a gas dryer must be moved, the quote should specify who disconnects, reconnects, and checks the gas connection.
What should be excluded clearly?
Roof work, siding repair, drywall patching, pest removal, appliance repair, booster fan installation, and gas line repair should be listed if they are outside the price.
