Vancouver pipes don’t burst as often as Prairie pipes – our winters are mild. But when they do, it’s almost always one of these five causes:

**Freeze events (December – February).** Most Vancouver burst pipe calls cluster around the 3-5 deep-cold snaps we get each winter, typically when overnight temps drop below -5°C for 48+ hours. Pipes most at risk: exterior hose bibs that didn’t get winterized, uninsulated crawlspace runs, garage-mounted laundry hookups, and any plumbing on the north-facing exterior wall of a 1970s-1990s build. We see a 3-5x spike in burst calls within 36 hours of the temperature climbing back above freezing – because the ice plug melts and water immediately flows out the crack.

**Aging Poly-B fittings (1978-1995 era homes).** Polybutylene plumbing degrades from chlorine in BC water. The original acetal plastic fittings fail first – usually at an elbow or tee inside a wall. See our [Poly-B replacement page](https://mambadrainageservices.com/plumbing-contractor/poly-b-pipe-replacement-vancouver/) for the long-term fix.

**Galvanized steel corrosion (pre-1965 homes).** East Vancouver heritage homes with original galvanized pipes are at end-of-life. Pinhole leaks turn into bursts when corrosion finally eats through the wall. Spot repairs are temporary – replacement is the real fix.

**Water hammer / pressure spikes.** Quick-close valves (washing machine, ice maker, dishwasher) create pressure surges that exceed pipe rating. Common in homes without water hammer arrestors and homes with high static pressure (over 80 PSI – common in Burnaby and parts of West Van).

**Construction damage.** Drilling, nailing, or excavation that hits a buried pipe. We see this often in renovations – the contractor opens a wall not knowing what’s in it.

Whatever the cause, the emergency response is the same: shut off water, isolate the leak, dry the area, repair permanently. We bring the gear and parts to do all four in one visit.

**Verify water is off.** If you couldn’t find the main, we will. If your shutoff is corroded and won’t close, we install a new one as part of the repair.

**Locate the burst.** Often obvious (water spraying from the wall), sometimes hidden behind drywall or in a ceiling. We use thermal imaging and acoustic leak detection to pinpoint without unnecessary demo.

**Open the wall / ceiling cleanly.** 8×8-inch access cut at the burst location only, not random demo. Drywall debris swept and bagged.

**Repair the pipe.** Copper sweat repair, PEX SharkBite, or PEX crimp depending on the pipe material and access. We bring all three on every emergency truck.

**Pressure test.** Re-pressurize the system to 60-80 PSI and verify no other leaks before closing up. Camera in adjacent walls if there’s any concern about secondary damage upstream/downstream of the original burst.

**Pump out standing water.** Submersible pump (2,500 gph) to remove what’s on the floor. Shop vac for residual. We don’t do drywall/floor remediation – we coordinate with the restoration contractor your insurance picks.

**Drywall patch (optional).** We can patch the access cut with proper drywall + tape + mud + paint match for $189-$389 add-on. Or leave clean cuts for your drywall contractor.

**Documentation.** Photos before/during/after, parts used, labour hours. Emailed to you within 24 hours for your insurance file.

**Emergency call-out + diagnostic:** $99-$149 – waived if you proceed with the repair the same visit.

**Single-section burst repair (copper, PEX, or PEX SharkBite, exposed location):** $289-$589 same visit including parts.

**Single-section burst repair (in-wall, requires drywall access cut):** $389-$789 including the access cut. Drywall patch + paint match optional add-on at $189-$389.

**Frozen pipe thaw + repair:** $389-$789 including hot-water hydro thaw and repair of any cracked sections.

**Galvanized spot replacement (one failed section):** $489-$889 – we usually recommend a full re-pipe quote since galvanized failures cascade.

**Poly-B emergency patch + quote:** $349-$649 for immediate stabilization. Full Poly-B re-pipe quoted separately.

**Main water line burst, on property:** $1,200-$3,800 depending on access (under driveway adds $400-$1,200) and depth.

**Main water line burst, under boulevard / road (City right-of-way):** $4,500-$9,800 including City Water coordination and asphalt restoration. Trenchless options available.

**Water hammer arrestor install (one fixture):** $189-$289.

**Pressure Reducing Valve install (whole-home, if static pressure over 80 PSI):** $689-$1,289 installed at water main.

**Strata common-line burst (residential building):** custom quoted – typical $1,200-$3,800 for single common-line section, more if multi-unit damage.

**After-hours surcharge for non-emergency overnight calls:** +$99. Active flooding/burst = NO surcharge. We don’t penalize you for an emergency you didn’t choose.

Firm prices on the call after symptom intake. Locked once we arrive and confirm.

**How fast can you actually get here?**
Vancouver core: 30-45 min. Burnaby / Richmond: 45-60 min. New Westminster: 60 min. Surrey / Delta: 75-90 min. We name the arrival window on the call – if we slip by more than 15 minutes, we call you before you call us.

**Do you charge extra for weekends or middle-of-night calls?**
For active flooding / burst pipes – no. Same price as daytime. For non-emergency overnight calls – $99 surcharge. We don’t penalize emergencies you didn’t choose.

**Can you repair on the first visit?**
Yes, 95% of the time. We carry copper, PEX, PEX SharkBite, valves, water hammer arrestors, and a portable PEX crimper on every emergency truck. The only repairs that require a second visit are buried main-water-line bursts that need excavator scheduling.

**Will my insurance cover the repair?**
Usually yes for the damage caused by the burst (drywall, flooring, contents), depending on policy. The PIPE repair itself may or may not be covered – that varies by policy. We provide written scope and photo documentation in the format BC insurers need.

**What about water cleanup / mould remediation?**
We pump out standing water and dry the immediate area, but full restoration (drywall removal, mould remediation, flooring) requires a restoration contractor (Belfor, ServiceMaster, etc.). Your insurance company will recommend one. We coordinate the handoff.

**My pipes are Poly-B – are they all going to burst?**
Eventually, yes. Poly-B fails progressively. We do an emergency patch for the active burst, then quote a full Poly-B re-pipe on a planned schedule. See our [Poly-B pipe replacement page](https://mambadrainageservices.com/plumbing-contractor/poly-b-pipe-replacement-vancouver/) for details.

**Do you serve strata buildings?**
Yes – common-line bursts coordinated with property manager and council. Certificates of service for the building file. After-hours response standard. $5M liability + WCB.

**Do you offer financing for big repairs?**
Yes – Financeit 0% interest up to 24 months on jobs over $2,000. Most main-line and re-pipe jobs qualify. 90-second online application.

**Do you serve Burnaby, Richmond, Surrey, Delta?**
Yes – all of Greater Vancouver. Response times stretch to 90 minutes in the outer cities but we cover the full region 24/7 with the same dispatcher.
