Markham Duct Cleaning: Thorough, On Time, Every Job

Yes, and ideally before you unpack. Construction leaves drywall sand and sawdust in the runs of nearly every new build in Cornell, Berczy, and Victoria Hill. One post-construction cleaning means you never breathe it.

Certified and fully insured on every job. Ontario issues no trade licence for duct cleaning, so training, certification, and insurance are the credentials that actually separate real crews from door-to-door upsellers, and we carry all three.

We photograph the inside of your runs before starting and after finishing, in your house, and show you both before we leave. The proof is not a receipt, it is a picture of your own ductwork.

Nine times out of ten, vent. If the drum heats but towels come out damp after a full cycle, air cannot get out through the lint. We brush the run to the cap and measure airflow, and if the machine is the culprit we tell you straight.

Negative-pressure vacuum connected at the furnace, registers washed, each supply and return run brushed under suction, blower compartment cleaned, photos taken. Most Markham homes run three to four hours end to end.

In two stages. Cleaning carries out the residue holding the odour, then a sanitizer treatment applied to the clean runs addresses what is left. Spraying without cleaning just perfumes dust, so we never do it.

Usually return-side leaks pulling unfiltered basement and wall-cavity air into the system. If a cleaning fades that fast, ask us to test and seal the duct leaks before paying for another clean.

All of Markham plus Unionville, Thornhill, Stouffville, Richmond Hill, and Newmarket. If you are just outside that ring, call anyway and we will confirm coverage.
