What a strata leak costs

A minor leak in a BC strata costs about $930 to fix. One that needs a professional runs about $4,800, and a serious one about $28,000, which is just past the deductible most BC buildings carry for water damage.

Council minutes rarely say much about a leak. A stain on a ceiling, a plumber, a restoration company, and every so often a dollar figure: the invoice, the estimate, or the deductible the strata had to pay. We took 2,000+ samples drawn from our pool of BC strata reviews, pulled the water incidents the council and general-meeting minutes put a price on, and sorted them by how bad the minutes say they were.

Three kinds of leak, three price levels

We grade each incident from the way the minutes describe it. A minor leak is a quick fix with little damage. The middle grade needs a professional repair: a plumber opening a wall, a roofer, a drywall patch. A serious leak means major damage, extensive remediation and, often, an insurance claim.

The steps are steep. A minor leak has a median cost of about $930, with the middle half of incidents between $500 and $2,100. A leak that needs a professional comes in at about $4,800, middle half $2,500 to $9,300. A serious leak has a median of about $28,000, and the middle half runs from $15,000 to $68,000. That is about thirty times the cost of a minor one.

Across every leak with a price in the minutes, the median is about $6,500. About 44% cost less than $5,000, about 23% reach $25,000, about 13% reach $50,000 and about 6% reach $100,000 or more.

The $25,000 line

On the latest BC strata policies, the median water-damage deductible is $25,000. About half of buildings carry exactly that, about a quarter carry $50,000 and about 7% carry $100,000 or more. Below the deductible, the insurer pays nothing, so the strata pays the repair out of its operating budget and, where the bylaws allow it, may try to recover it from the owner responsible. [1] [2]

That puts most leaks below the line. Fewer than one minor leak in a hundred reaches $25,000, and about one professional repair in sixteen does. Serious leaks are the ones that cross: about six in ten cost $25,000 or more. The deductible also shows up in the numbers themselves. About one serious leak in eleven is recorded at exactly $25,000, one in eighteen at exactly $50,000 and one in forty at exactly $100,000, because what the minutes record is often not the repair bill but the deductible the strata paid before the insurer took over. Where the minutes mention insurance, a claim or the deductible, which is about one priced leak in fifteen, the median cost is $25,000.

The most common price of a serious leak in BC strata minutes is not a repair bill. It is the deductible.

What fails decides the bill

Among serious leaks, envelope failures cost the most, a median of about $40,000, with the middle half reaching $120,000: water that comes in through walls and balconies has usually been at work for a while before anyone sees it. Drainage follows at about $38,000 and floods at about $36,000. Sprinkler leaks have a median of about $33,000 and roofs about $30,000, and both have an upper edge near $100,000. Plumbing, burst pipes and fixture overflows all sit at a median of $25,000, the deductible again.

For leaks that need a professional, the cause matters much less. Every cause lands between about $3,700 (roofs) and $6,400 (drainage), with plumbing at about $4,600.

How far it travels

Distance is the other driver. A BC leak that stays inside one unit has a median cost of about $3,000. One that touches only common areas is about $5,000. Once it reaches the unit next door or below, the median is about $9,800; through the whole building, about $20,000; across several floors, about $24,000. About 8% of single-unit leaks reach $25,000, against about half of the ones that cross floors.

Per door

Spread over the building, a serious leak works out to a median of about $330 per unit, with the middle half between $140 and $750. Building size moves that a lot. In BC stratas with fewer than 50 units, a serious leak is about $790 a door; in buildings with 100 units or more it is about $220 a door, even though the whole-building cost is higher, about $40,000 against $25,000.

What to do with this

• If you are buying: look for the dollar figures next to leaks in the minutes. A run of repairs in the low thousands is ordinary. Several leaks at the deductible usually means several insurance claims, and insurers look at claims when the policy renews.

• If you own a unit: find out your building's water deductible and what the bylaws say about charging it back. Your own policy can cover that amount, but only if its deductible coverage is at least as high. [1] [3]

• If you are on council: most leaks never reach the insurer. Repairs below the deductible come out of the operating budget, which is worth a line of its own.

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. Each water incident is counted once, with the cost the minutes record for it, its severity graded from the minutes' description, its cause and how far it spread. Per-unit values divide the cost by the corporation's total unit count. The water deductible is the one on each building's latest insurance certificate. Figures are medians and the middle half (p25 to p75) or shares of incidents, rounded to two significant figures. No building is identified.
