Ottawa winters are among the harshest of any major city in the world, and they create unique emergency repair situations that homeowners in milder climates never face. With temperatures regularly reaching minus 25 to minus 35 degrees Celsius, heavy snowfall averaging 235 centimetres annually, and ice storms that can devastate power infrastructure, Ottawa homeowners need to be prepared for winter-specific emergencies. Frozen and burst pipes, furnace failures, ice dams causing interior water damage, roof collapses from snow load, and ice-storm damage are all real risks during an Ottawa winter. T...
Frozen pipes are the most common and potentially most damaging winter emergency in Ottawa.
Insulate all pipes in exterior walls, unheated basements, crawl spaces, and garages. Open cabinet doors under sinks on exterior walls during extreme cold. Keep indoor temperature at 16 degrees minimum, even when away. Let faucets drip during extreme cold (minus 20 and below). Disconnect and drain al...
If you suspect a frozen pipe (no water flow, frost on exposed pipe), apply gentle heat with a hair dryer or heating pad. Never use open flame. If a pipe has burst, shut off the main water valve immediately and call an emergency plumber. Emergency pipe repair costs $200 to $600 for the plumbing fix a...
A furnace failure during an Ottawa cold snap is a genuine safety emergency.
Check the thermostat (batteries and settings). Check the furnace filter. Check the power switch and circuit breaker. Check for error codes on the furnace control panel. If you smell gas, leave the house immediately and call 911 and Enbridge Gas emergency (1-866-763-5427). If the furnace will not res...
Emergency furnace service call: $200 to $400 plus repair costs. Common emergency repairs: ignitor ($150 to $350), control board ($300 to $600), blower motor ($400 to $800), gas valve ($300 to $500). If the furnace is over 15 years old and the repair cost exceeds $1,000, emergency replacement may be ...
Ice dams form when heat escapes through the roof, melting snow that refreezes at the eaves.
If water is entering your home through the ceiling due to an ice dam, remove interior water and protect belongings. Do not attempt to remove ice from the roof yourself — it is dangerous and can damage roofing. Call a professional ice dam removal service. Professional ice dam removal using steam cost...
Ice dams are caused by inadequate attic insulation and ventilation. The permanent fix is upgrading attic insulation to R-60 and ensuring proper soffit-to-ridge ventilation. This costs $2,000 to $4,000 but eliminates the problem permanently. Heating cables along eaves are a band-aid solution at $500 ...
Heavy snow loads can threaten roof structural integrity.
Warning signs include doors that suddenly stick or won't close, cracking sounds from the roof or attic, sagging ceiling or roof line, and cracks in walls or ceiling. If you observe these signs, evacuate the area beneath and call a structural contractor immediately. Flat and low-slope roofs are most ...
Ice storms are an Ottawa reality, with major events occurring every few years.
A backup generator ($500 to $5,000 depending on type) is the best preparation for extended power outages. At minimum, a portable generator can power a furnace blower, sump pump, and refrigerator. Have battery-operated carbon monoxide detectors (critical when using generators or alternative heating)....
Common ice storm damage includes downed power lines and electrical service damage ($500 to $3,000 to repair), tree damage to roofs and siding ($1,000 to $20,000), and ice damage to gutters and eavestroughs ($300 to $1,500). Document all damage with photos for insurance claims. Emergency tree removal...
Apply gentle heat with a hair dryer. Never use open flame. If a pipe has burst, shut off the main water valve immediately and call an emergency plumber. Prevention is key: insulate pipes and keep heat at 16°C minimum.
Insulate pipes in exterior walls, let faucets drip during extreme cold, keep heat at 16°C minimum, disconnect outdoor hoses, and consider heat cables for vulnerable pipes. Prevention costs $100 to $500 vs $5,000+ for damage repair.
Professional steam ice dam removal costs $400 to $1,200 per visit. The permanent fix is attic insulation upgrade to R-60 ($2,000 to $4,000).
Remove snow if it exceeds 2 feet on a flat/low-slope roof or if you notice warning signs (sagging, cracking sounds, sticking doors). Hire a professional — roof snow removal is dangerous.
Strongly recommended. A portable generator ($500 to $2,000) powers essential systems during outages. A whole-home standby generator ($5,000 to $15,000 installed) provides automatic backup.
