Frozen Pipe Repair Airdrie — Thawing, Burst Repair & Prevention

Open the tap that pipe feeds and leave it open.

A pipe usually doesn't split at the ice itself — it splits between the ice and a closed fixture downstream, where trapped water has nowhere to go as pressure builds. Opening the tap removes that pressure and tells you the moment flow comes back.

Then raise the heat in that area, open cabinet doors under sinks on exterior walls, and apply gentle heat if you can safely reach the section. Call 587-834-3668 and we'll thaw it properly and work out why it froze.

Wind, mostly.

Airdrie sits higher and more exposed, and a lot of the newer areas back onto open ground with nothing to break the wind. Moving air pulls heat out of a wall cavity far faster than still cold does, so a bump-out on an exposed elevation can freeze on a night that a sheltered inner-city street rides out at the same temperature.

It's also why air sealing matters more here than insulation depth. Insulation slows heat loss; sealing stops the cold air getting into the cavity in the first place.

PEX is more forgiving than copper, but it is not freeze-proof and it's frequently oversold as such.

It can expand somewhat as water freezes inside it, so it survives some freezes that would split copper. What it doesn't survive is enough ice, enough pressure, or repeated freeze-thaw cycling — and chinooks deliver exactly that cycling. The fittings are often the weak point rather than the tubing itself.

So PEX buys you tolerance, not immunity, and it isn't a reason to skip sealing the cantilever.

If you can reach it, often yes.

Safe: a hair dryer, a heat gun on low, a space heater aimed at the area, warm towels. Work from the tap end back toward the blockage so meltwater can escape, and keep the tap open throughout.

Never safe: a blowtorch or any open flame. It's a serious fire risk inside a wall, and it will destroy PEX on contact.

If the frozen section is inside a wall or you can't locate it, that's the point to call rather than start cutting drywall.

Lines serving buildings you only heat when you're using them are the acreage version of this problem, and they need a decision rather than hope.

Either the line gets drained down for the season, or it gets insulated and heat traced so it stays above freezing regardless of whether the building is warm. Which one makes sense depends on how often you use the space through winter.

We'll look at the run, tell you which approach fits, and quote it in writing.

Usually, but check rather than assume.

A pipe can split while frozen and stay sealed by its own ice, only starting to leak when it thaws — which in Airdrie often means when a chinook arrives days later.

Look at the ceiling below the run, the rim joist, and anywhere the pipe crosses an unheated space. Damp drywall, a stain, or a musty smell is the sign. If you find one, shut the water off at the main and call.

Same day for burst pipes, and we dispatch Airdrie locally out of Coopers Crossing rather than routing a truck up from Calgary.

That matters most in a cold snap, when everyone needs someone at once and the drive time is the difference between an hour and half a day.

Before we arrive: shut off the main, open a low tap to drain the pressure, and stay out of any water near electrical. A real person answers at 587-834-3668.
