What to Expect During a Dryer Vent Cleaning Visit

Before we arrive

Most appointments are scheduled the same day or the next morning. We'll text you a 30-minute arrival window when the technician is on the way, plus a name and a photo so you know who to expect. The technician arrives in a clearly marked vehicle.

You don't need to do anything to prepare. Don't move the dryer — that's part of the job. Don't try to clean the lint trap housing first — we want to see the existing state of the system. If your dryer is in a tight closet or stacked configuration, mention it when you book so we know which equipment to bring.

Arrival and walkthrough (5 minutes)

• The technician introduces themselves, shows ID and a license card if you want to see it.
• You walk them to the dryer. They confirm where the vent terminates outside — wall cap, roof cap, or somewhere else.
• Quick conversation about why you booked: long dry times, burning smell, or just routine. The answer affects the order of work.
• Confirmation of the flat-rate quote you were given over the phone. If anything looks materially different from what you described — a stacked laundry instead of side-by-side, a roof termination instead of a wall — they'll explain the price difference before starting. No surprises mid-job.

Setup and disconnection (5 minutes)

• Drop cloths laid down behind and around the dryer.
• Dryer pulled out from the wall.
• Power and gas (if applicable) safely shut off.
• Transition hose disconnected from both the dryer and the wall stub.
• Visual inspection of the transition hose: kinks, sags, lint, signs of damage. We'll show you anything notable.

Cleaning the run (25 to 60 minutes)

This is the bulk of the work and where the actual results come from.

• HEPA vacuum positioned at one end of the run.
• Rotary brush sized to your duct diameter (almost always 4 inches for residential) attached to a power tool with flexible drill rods.
• Brush fed in from the other end, typically the dryer side. The brush spins at 1,000+ RPM, agitating lint off the duct walls. The vacuum on the opposite end pulls the dislodged lint immediately, so it doesn't migrate further into the run.
• The crew alternates ends as needed, especially around elbows. A long run with multiple elbows requires several passes from each direction.
• Periodic checks through cleanout ports or transition fittings to confirm progress.

You'll hear the brush motor and the vacuum running. You may hear knocking as the brush works through tight elbows. The technician may move from inside to outside and back several times.

Servicing the exterior cap (5 to 15 minutes)

• The exterior wall or roof cap is removed (or accessed in place if removal isn't necessary).
• Louvers and the flap are cleaned of lint, mud, leaves, ice or other debris.
• If the cap is damaged or stuck, the technician will recommend replacement and quote it on the spot. Caps are inexpensive and we typically have spares on the truck.
• The flap is verified to swing freely and seal properly when not in use.

Airflow verification (5 minutes)

This is the part that distinguishes a real cleaning from a "we ran a brush through it" cleaning. The technician:

• Reconnects the transition hose temporarily.
• Runs the dryer on the highest-airflow cycle (usually a no-heat fluff cycle).
• Measures airflow at the exterior cap with an anemometer.
• Confirms the reading is at or above 1,500 ft/min — the threshold for a properly functioning 4" residential vent.

If airflow is below the threshold despite a thorough cleaning, the line itself has a problem (collapsed flex, crushed section, off-code routing) and a cleaning alone won't fully resolve the issue. The technician will tell you, show you on camera if helpful, and quote the next step separately. You're not charged the cleaning price for a vent that didn't actually clean.

Final reconnection and cleanup (10 minutes)

• Transition hose properly reconnected and clamped on both ends.
• Dryer pushed back into place — but not so close to the wall that the transition hose is crushed.
• Brief operational test cycle to confirm normal operation.
• All lint and debris bagged and removed from the property.
• Drop cloths picked up.
• Work area left as clean as it was when we arrived. Cleaner, in most cases.

Walkthrough and payment (5 minutes)

• Before-and-after photos of the run shown on the technician's tablet.
• Honest readout: what shape was the line in, was anything found that needs follow-up, what's the recommended next service date.
• Written invoice emailed at the time of payment, plus a service certification letter on request (often required for HOAs, multi-family insurance documentation, and pre-listing or pre-purchase due diligence).
• Payment: card, check or cash. Recurring service can be set up at this time if you want to lock in next year's appointment.
• Any questions you have, answered straight.

What an honest visit looks like

You can tell whether you got a real cleaning by what the technician shows you and what they don't try to sell you. Real signs:

• You see actual lint coming out — typically a substantial amount, sometimes literally pounds of it.
• You're shown an anemometer reading at the exterior, not just told "looks good."
• If repairs are recommended, you're shown the problem on camera and given a written quote you can take to a second opinion if you want.
• The technician doesn't pressure you to commit to repairs on the spot.
• The price you pay matches the price you were quoted, unless something materially different was discovered and discussed with you first.
