Post-Renovation and New-Home Duct Cleaning in Kitchener
A renovation puts more into your ducts in three weeks than normal living does in ten years. The furnace was running the whole time.
Kitchener's south end has been under construction for years, and the older neighbourhoods are in a steady cycle of kitchen, bathroom and basement renovations. Both produce the same result in the ducts: drywall dust fine enough to pass a builder-grade filter, sawdust, insulation fibres, and whatever the trades dropped down the open floor boots. This page covers the clean-out.
New builds in Doon South, Huron Park and along the ION line
During construction the duct boots are open holes in the subfloor for weeks. Screws, drywall offcuts, sawdust, packaging and coffee cups go down them. Then the drywall is sanded, and the builder runs the furnace for winter heat through that sanding, often with a temporary filter or no filter. The dust coats the blower wheel, packs into the coil and settles along the bottom of every branch. The builder's final clean wipes the registers. It does not touch any of that.
The right time for a new-build duct cleaning is after the last trade has left and before you move furniture in, or as soon after closing as you can manage. In a stacked townhouse or condo along the ION corridor the runs are short, but the drywall dust is the same, and the coil is just as coated.
Renovations in older Kitchener houses
A kitchen gutted in a Forest Heights sidesplit, a basement finished in Stanley Park, a bathroom reworked in a Cedar Hill century home: the plastic sheeting over the doorway helps, but the return grille in the hallway is still pulling air from the work zone every time the furnace runs, and the supply registers in the room being renovated were probably open the whole time. Plaster dust from an old house is worse than drywall dust because it is finer and there is more of it. Renovations that opened walls also drop decades of wall-cavity debris — old insulation, mouse nests, sawdust from the original build — into runs that pass through those walls.
A post-renovation clean covers the whole system, not just the renovated room. The dust has already travelled. It is quoted as a full job with an allowance for heavier debris.
What the clean-out involves
- Negative air on the supply and return trunks, as on any complete job.
- Access openings cut into the trunk so large debris — offcuts, screws, packaging — can be pulled out by hand, because it will not travel to the vacuum on its own.
- Every run whipped and brushed from the register back to the trunk.
- The blower compartment, blower wheel and evaporator coil cleaned. This is not optional on a post-construction job; the coil is where the drywall dust ends up.
- Returns opened and cleaned, including any joist-bay returns that were exposed during a basement renovation.
- Access openings sealed with metal plates, registers cleaned and reinstalled, new filter in.
Basement renovations in particular
A finished basement in a Forest Heights or Stanley Park house is the renovation that puts the most into the ducts, because the trunk and every joist-bay return are in the room being worked on. Drywall dust goes straight into the open returns. If the ceiling is being closed in, it is worth having the ducts cleaned and any foil sections replaced by the heating contractor before the drywall goes up, because after that the only access is through the registers.
Order of operations with the other trades
Duct cleaning goes after the painter and the flooring installer and before the post-construction house cleaner. If the cleaner comes first, the ducts blow drywall dust back onto the surfaces they just wiped. If you are working with a builder or a renovation contractor on a schedule, tell us and the day gets slotted where it belongs. Builders and renovators with several units in Huron Park or Doon South can book them as a block.
What is not part of this
Debris left on the floors and in the garage is a junk removal job. Surface cleaning of the house is a cleaning company's job. Dryer exhaust vents — which are often crushed or disconnected during a renovation — are a separate service not offered here, and worth checking with someone who does that work. HVAC modifications the renovation needed, such as a new run to a finished basement, are a heating contractor's job before the clean, not after.
Frequently asked questions
Does the builder clean the ducts before closing?
Rarely, and a builder's final clean usually means the registers were wiped. Ask the builder in writing what was done. If the answer is vague, assume the ducts hold whatever went into them during construction, and look down a floor boot with a light before you move in.
How soon after a renovation should the ducts be cleaned?
After the last dusty trade — drywall, sanding, flooring — is finished and before the final surface clean. Doing it earlier means doing it twice. Doing it after the cleaners means the cleaners were wasted.
Can you do all the units in a new development?
Yes. Builders and renovators working several houses or townhouse units in Doon South, Huron Park or a downtown project can book them together, and they are quoted as a block.
