Things minutes say about lint
3 min read
About one BC strata leak in 155 turns out to be the dryer vent. The roofer finds nothing, the ceiling keeps dripping, and the fix costs about $47 a door.
The story starts the same way in building after building. An owner on an upper floor reports a ceiling stain. Council calls the roofer. The roofer goes up and finds a perfectly good roof. The stain comes back anyway, and eventually somebody thinks to look at the dryer vent.
Across 2,000+ samples drawn from our pool of BC strata reviews, about one water incident in 155 traces back to a dryer duct, a lint blockage or the booster fan that pushes dryer air up through a tower. In about one case in five the leak is logged as a roof, wall or window problem. The mechanism is the same every time. Warm, wet air leaves the dryer and travels a long way to the outside. Lint narrows the duct, the air slows down and cools, the moisture condenses, and the water runs back along the duct until it finds a joint and a ceiling. Dryer ducts and condensation turn up together in the minutes again and again.
The roofer finds a perfectly good roof. The leak turns out to be laundry.
The damage is usually small. About three in five of these incidents are minor, a third need a professional, and serious ones are rare, about one in forty. Two in three stay inside one unit. The investigation is less small. The minutes record camera scopes of duct runs, epoxy injected into ceilings, and ducts found crushed, pinched, badly sealed or simply disconnected inside the ceiling. In tall buildings the booster fan gets its own chapter, usually seized with lint or broken. Several buildings cleaned the vent and found it still dripping afterwards, so cleaning is not always the whole fix. And in a fair number of cases the leak ends with a note that the duct was on the owner's side, which turns a strata problem into an owner's bill.
Then there is the cure. About one BC strata in eight records a building-wide dryer vent cleaning in its minutes, and about one approved budget in three carries a dryer vent cleaning line, at a median of about $43 a door a year. Where the minutes give a price for a building-wide clean, the median is about $2,600 for the whole building, or about $47 a door, with the middle half between $34 and $58. For comparison, the median BC leak with a dollar figure in the minutes costs about $6,500. Annual cleaning is by far the most common schedule named. A few buildings clean twice a year, a few every other year, and a handful have written the schedule into their rules.
Water is not even the main reason they do it. About three cleanings in eight are recorded as fire safety work. Lint is what dryer fires start in, and failure to clean is the leading factor in residential dryer fires in the United States. [1] The BC safety regulator describes how lint hardens on the inside of a vent, catches more lint and eventually restricts the airflow enough to overheat the dryer. [2] The minutes rarely put it that way. They just say the vents were cleaned, building-wide, and move on to the next item.
How we counted. Based on 2,000+ samples drawn from our pool of BC strata reviews. Figures come from the council and general-meeting minutes in those samples, mostly 2023 to 2026, and from the approved operating budgets. Water incidents and recorded work were searched for dryer ducts, lint and booster fans. Every pattern described appears in at least three unrelated buildings; nothing is quoted, amounts are rounded and no building is identified.

What happened in a building, and whether it is normal
StrataReports reads the full document package of one strata or condo building and reports what happened in it. It then compares the whole building with similar buildings nearby, from finances and insurance to repairs, the condition of its components and disputes, and shows what is normal and what is not. Every finding links to its source page.
