What we run into most

Household Drain Trouble We Repair Fast

We've seen every issue a frozen pipe can cause. Here are the problems our clients call us about most often.
🚱

No Water Coming From a Faucet

A faucet that suddenly stops producing water usually means ice has blocked the supply line somewhere upstream. Left alone, pressure can build behind the blockage and crack the pipe. We locate the freeze point and thaw it safely without cutting into walls unnecessarily.

💦

Pipe Has Already Burst and Is Leaking

A burst pipe releases water continuously the moment the ice plug melts, often behind a wall where it goes unnoticed at first. Left unaddressed, the water spreads through subfloors and framing fast. We shut off the supply and repair the damaged section immediately.

🥶

Frost Visible on an Exposed Pipe

Visible frost on a pipe in a basement or crawl space is an early warning sign that ice is forming inside. Ignoring it risks a full freeze and possible burst within hours. We thaw the section professionally and recommend insulation to prevent a repeat.

🔁

Same Pipe Freezes Every Winter

A pipe that freezes repeatedly in the same spot usually has an insulation gap or exterior wall exposure that a one-time thaw never fixes. Continuing to thaw it each year just delays an eventual burst. We assess whether insulation or rerouting solves the problem permanently.

🏚️

Water Damage Spreading From a Burst Pipe

Water from a burst pipe travels through subfloors and wall cavities before it becomes visible on a ceiling or floor. Left unaddressed, mold can begin forming within 24 to 48 hours. We assess visible water intrusion and flag areas needing drying or restoration.

Unsure Whether to Thaw or Replace a Pipe

Homeowners often cannot tell if a frozen section just needs thawing or if hidden damage means replacement is safer. Guessing wrong risks a surprise leak once the ice clears. We inspect the pipe before applying heat and recommend the right approach honestly.

🧱

Pipe Freezing in an Exterior Wall

Pipes routed through exterior walls with minimal insulation are the most common freeze location in any home. Left unprotected, that same section will likely freeze again during the next cold snap. We install insulation sleeves or heat tape to stop the pattern.

👃

Strange Odor Coming From a Drain

A frozen section can trap sewer gases with nowhere to vent, producing an unusual smell near a drain. Left unresolved, this often points to a broader freeze affecting more than one fixture. We trace the affected line and clear the blockage safely.

⚠️

Old Galvanized Pipe Bursting From Corrosion

A burst in aging galvanized pipe is sometimes a symptom of corrosion throughout the system rather than an isolated freeze issue. Patching one section without addressing the rest often means another burst soon after. We flag broader corrosion honestly before recommending a fix.

Natalie C.

Came out fast during a cold snap

Our kitchen faucet stopped working overnight during a deep freeze and Core Ontario Plumbing Services had someone out the same morning. They thawed the line safely without opening a single wall. Huge relief.

Ben H.

Caught a hidden crack before it flooded

The technician checked the frozen section for damage before thawing it and found a hairline crack we never would have known about. He fixed it before applying heat, which saved us from a surprise flood once the ice cleared.

Farrah A.

Good repair, took a little longer to source parts

Our galvanized pipe needed a specific fitting that wasn't on the truck, so it took an extra trip the next day. The repair itself was solid and the plumber explained everything clearly before leaving.

Trevor M.

Stopped a burst pipe from ruining our basement

Water was already pooling when the plumber from Core Ontario Plumbing Services arrived. He shut off the supply, cut out the damaged section, and had new pipe in within the hour. Cannot thank the team enough for the quick response.

Simone K.

Fixed a recurring freeze for good

The same pipe froze three winters in a row before we finally called Core Ontario Plumbing Services. They rerouted it away from the cold exterior wall and it hasn't frozen since, even during the coldest nights this year.

Owen D.

Explained exactly why it happened

Instead of just fixing the immediate problem, the technician walked me through why that specific pipe kept freezing and what insulation would prevent it long term. Genuinely useful advice, not just a quick patch job.
