What goes through the wall
Every hole the builder cut, sealed once.
A typical house has eight to fifteen penetrations and most of them were sealed exactly once, on the day they were installed. These are the ones we reseal — all of them, for one price.
Range hood and furnace vents
High-temperature terminations, sealed with the right grade.
Hose bibs and gas lines
Small penetrations that take a surprising amount of water on the weather side.
AC line sets and condensate
The bundle of lines into the wall, usually stuffed with foam and nothing else.
Hydro mast, cable and phone entries
Service entries are rarely sealed properly, and they are often the draft you can feel.
Fresh-air and HRV intakes
Sealed at the wall without blocking the airflow the appliance needs.
The joints we reseal
Gold marks the joint.
Recent pipe and vent work
Sealed at the wall, not smeared over it.
From the owner's phone — no staging, no filters.
Vent covers
Cracked, stuck or missing covers, replaced.
Plastic covers go brittle in the sun. After ten or fifteen winters the louvres crack, the flapper sticks open or the whole hood is simply gone — and now the duct is open to the weather, to insects and to birds.
A working damper matters. An exhaust that cannot close lets cold air straight in and lets warm, wet air condense and freeze in the duct behind it.
We carry standard sizes and swap the cover while we are sealing the penetration. If a duct behind it is damaged, that is HVAC work and we tell you so.
What is included
- A new exterior cover with a working damper
- Old cover removed and the opening cleaned
- The flange sealed to the wall — the joint that actually leaks
- Colour-matched sealant where it shows
- Same visit as everything else on your cart
Pricing
One price for the whole house.
Tick the reseal, count the covers that need replacing, and add it to your cart. If your window job has 16 or more openings the reseal is on us.
Every job carries a minimum charge — before HST, a little more when the job is several small items — and books with a deposit plus HST.
Straight answers
Pipe and vent questions.
What counts as a pipe or vent?
Anything that passes through the wall: dryer and bathroom exhausts, range hood vents, hose bibs, gas lines, air-conditioner line sets, the hydro mast and cable entries, and the fresh-air intake for the furnace. If it goes through the wall, it is in the count — and it is one flat price for all of them.
Why is it free with a bigger window job?
Because we are already there with everything set up. On a house with sixteen or more openings the penetrations are a few extra joints on walls we are already working on, so we include them rather than bill for them.
Do you replace the vent itself or just the cover?
The exterior cover — the hood, louvre or flapper assembly on the outside of the wall. Replacing the duct behind it is HVAC work; if a duct is the problem we will say so.
My dryer vent flap sticks open. Is that a problem?
Yes — an open flapper is a hole in the wall for cold air, insects and, in winter, condensation that freezes inside the duct. A new cover with a working damper is one of the cheapest fixes on the house.
