Seven questions, about 40 seconds. Built from what our technicians actually find in King City homes.
Cleaning only helps if the duct is intact. We replace crushed foil with rigid or semi-rigid metal, reseal joints that came apart inside a joist bay, re-route runs that were never compliant, and replace exterior hoods that no longer close in King City.
Common failures we replace
Torn or collapsed flex behind the appliance, ducts terminating into an attic or soffit, screw penetrations catching lint, unsealed joints leaking into framing, and broken hood dampers.
Rigid metal, foil-taped joints
Concealed runs get smooth rigid metal with foil-taped joints and no interior fasteners. That is both the code requirement in King City and the reason the duct stays clear longer.
Re-routing that actually works
Too many elbows or an uphill run guarantees repeat blockages. Where the route is the problem, we redesign it rather than cleaning the same failure every year.

How the visit works in King City
- 1
Airflow test before we start
We measure real exhaust airflow at the exterior hood so you see the honest 'before' number for your home in King City.
- 2
Camera scan of the duct
A push camera runs the elbows, transitions, and termination so the blockage is located, not guessed at.
- 3
Rotary brush and HEPA vacuum
A counter-rotating brush breaks the lint mat loose while a negative-pressure HEPA vacuum captures it. Nothing blows back into the laundry room.
- 4
Termination and damper service
Exterior hood cleared, damper flap freed, and bird nests or lint-catching screens removed.
- 5
Transition and connection check
Crushed foil behind the dryer is straightened or replaced with rigid or semi-rigid metal and properly clamped.
- 6
After test and photo report
We re-measure airflow and email before/after numbers with photos, so the improvement is documented rather than promised.
What King City customers say
4.9 out of 5 from 743 reviews across the GTA. A selection relevant to this service below.
Stacked unit in a tiny closet. They pulled it, fitted a proper periscope, cleaned the run, and put everything back exactly as it was.
Appliance tech had replaced the fuse twice. Diamond found the actual blockage. No failures since.
Removed the nest, fitted a proper damper, and explained why the old screened hood was the reason it kept happening.
Quoted a range on the phone, confirmed the exact number after seeing the run, and stuck to it.
Dryer Vent Cleaning FAQs — King City
Can you repair without opening walls?
In most homes in King City, yes — we work from the appliance side and the exterior termination, and tell you upfront if access is unavoidable.
How do I know the duct is leaking?
Humidity or a warm-lint smell in the laundry room while the dryer runs, or lint dust on nearby surfaces.
Is foil flex duct allowed at all?
Only as a short, exposed transition behind the appliance — never inside a wall, floor, or ceiling.
Do you handle townhouse and condo runs?
Yes, including shared shafts, booster fans, and the documentation building management asks for.
How long does a repair take?
Transitions and hoods take an hour or two. Re-routes are usually a half or full day.
Is the work warrantied?
Yes — a written workmanship warranty on all repairs in King City.
