What To Do If a Pipe Bursts in Your Home in Ontario and How to Fix It

Ah, the joys of Canadian winters—snowball fights, hot chocolate, and unfortunately… the occasional pipe burst. Whether it’s a deep-freeze in Waterloo or an unexpected plumbing pop in Cambridge, a burst pipe is one of those home emergencies you never see coming until your floors are floating, and your ceiling’s dripping like a leaky canoe. 

At LG Home Comfort, we know HVAC, plumbing, and what it takes to keep your home safe, warm, and dry. So, let’s walk you through exactly what to do when a pipe bursts—before it turns your cozy abode into a waterpark.

🛑 Step 1: Shut It Down, Fast

The first and most important thing you need to do in the event of a burst pipe emergency repair is shutting off the main water valve. Your shut-off valve is usually found in the basement, crawl space, or near the water meter. If you’re not sure where it is, now’s the perfect time to find it—before the Niagara Falls effect starts inside your walls. 

⚡️Bonus Tip: If water’s creeping near electrical outlets, flip the breaker for that area too. Safety first, eh? 

🔧 Step 2: Call Your Local Plumbing Pros

Time to call in the cavalry—aka LG Home Comfort’s plumbing experts. If you’re searching for burst pipe repair near me, we’ve got you covered across Ontario. Our team is on standby to patch, repair, or replace burst pipes fast. DIY fixes are fine in a pinch, but a professional plumber will check for hidden damage in your walls, joints, or floorboards that could cause future flooding. 

🧰 Pro Fact: Most pipe bursts don’t just happen in one clean spot. Water has a funny way of travelling, and so does the damage. Our experts can help assess water damage prevention and ensure the problem is contained.

🚰 Step 3: Drain the System

Open all your cold taps, flush the toilets, and if safe to do so, shut off your water heater and open the hot taps too. This relieves pressure in your pipes and reduces the chance of more water sneaking into unwanted places.

🔍 Step 4: Spot the Source

Not all water pipe bursts in house are obvious. Sometimes, they’re sneaky. Watch for: 

• Water stains or bubbles on your walls and ceilings 

• Puddles under cabinets or near baseboards 

• Weird gurgling sounds in your plumbing 

• Suddenly low water pressure

Can’t find it? Our leak detection techs can sniff out hidden pipe problems without tearing up your drywall.

🩹 Step 5: Contain and Patch (Temporarily)

If you’re the handy type, plug the leak with plumber’s tape, a patch kit, or even a towel and duct tape until help arrives. Place a bucket under the leak, move valuables out of the splash zone, and get your mop game on.

But remember—this is just a Band-Aid. Let the pros handle the surgery.

📸 Step 6: Document for Insurance

Your insurance provider’s going to want proof, so take photos of: 

• The leak itself

• All affected areas (floors, walls, furniture)

• Any soggy belongings

📂 Save receipts for all repairs and replacements. We’ve worked with insurance companies before, and LG Home Comfort can help you document the damage for a smoother claims process.

🧽 Step 7: Clean Up Like a Champ

Mop up standing water, run fans, and if you have a dehumidifier, fire it up. Moisture leads to mould, and mould leads to major headaches.

🔧 Need help with drying or restoration? We offer complete flood cleanup and HVAC system inspections to make sure your furnace or heat pump wasn’t affected by water damage.

FAQs

1. What causes pipes to burst in Canadian homes during winter?
   Pipes often burst in winter due to freezing temperatures causing water inside to expand and crack the pipe. In Canadian homes, especially in places like Waterloo, Cambridge, and the GTA, uninsulated pipes near exterior walls or basements are most at risk. LG Home Comfort offers pipe insulation and winter home prep services to stop pipe bursts before they start.
2. How do I know if I have a hidden pipe leak or burst?
   Watch for signs like sudden drops in water pressure, unusual puddles, musty smells, or mysterious spikes in your water bill. If you suspect a leak, call LG Home Comfort—we use advanced leak detection technology to spot and fix pipe issues fast, before they turn into major home disasters.
3. Can a burst pipe cause damage to my HVAC system?
   Yes—if water from a burst pipe reaches your furnace, ductwork, or smart thermostat, it can short-circuit components or cause mould to grow inside your HVAC system.
