Burst Pipe Water Damage: What to Do in the First 24 Hours
Step-by-step emergency response for a burst pipe in your home — what to shut off, what to document, when to call your insurer, and the mitigation mistakes that cost thousands.
A burst pipe can flood a home with hundreds of gallons of water in under an hour. What you do in the first 24 hours determines whether you face a $4,000 cleanup or a $40,000 reconstruction. This is the exact playbook IICRC WRT/FSRT and PMII CMR-certified restoration crews recommend for Ontario homeowners and commercial property managers.
Minute 0–15: Stop the source
- Shut off the main water valve. In most Ontario homes it is in the basement, near where the municipal supply enters the foundation. Turn the handle clockwise until it stops.
- Shut off electricity to the affected area at the breaker panel if it is safe to reach the panel without standing in water. If the panel is in the flooded area, leave it alone and call 911 or your utility.
- Open the lowest faucet in the house to drain residual pressure from the pipes.
- If the burst is on a hot-water line, shut off your water heater (gas or electric) to stop it from cycling against an empty tank.
Minute 15–60: Make the scene safe and call for help
- Move people and pets out of the flooded area.
- Lift small valuables, electronics, and area rugs out of the water.
- Do not use a household vacuum to extract water — only wet/dry vacuums or truck-mounted extraction units are rated for it.
- Call 24/7 emergency restoration dispatch. Every hour matters. Call (855) 3247-FLOOD for IICRC WRT/FSRT and PMII CMR-certified response across Kingston and Eastern Ontario.
- Call your insurance broker to open the claim and get a claim number. Most carriers have a 24/7 claims line.
Hour 1–4: Document everything
Before moving anything, photograph and video the entire affected area from multiple angles. Include:
- The failed pipe (a clear close-up shot)
- Standing water in every room
- Wet walls, baseboards, and flooring
- Damaged furniture and contents
- Any visible mould or staining
- Wide shots showing the extent of the spread
This documentation is critical for your insurance claim. Adjusters routinely reduce or deny claims where the cause of loss was not photographed before cleanup began.
Hour 4–24: Mitigation begins
Once restoration crews are on-site, the industry-standard water damage practices mitigation sequence runs:
- Water extraction with truck-mounted units (10x faster than wet/dry vacs)
- Moisture mapping with thermal imaging and penetrating meters to find hidden water in wall cavities and joist bays
- Removal of saturated porous materials — carpet pad, soaked wall materials below the waterline, wet insulation
- Antimicrobial application to prevent mould activation
- Air mover and dehumidifier placement sized to the cubic footage per industry-standard water damage practices
- Daily psychrometric monitoring to dry standard
If you start extraction within 4 hours of the burst, most homes can be dried without major demolition. Wait 48+ hours and you are usually looking at flood cuts, wall materials replacement, and a much longer reconstruction phase.
What NOT to do in the first 24 hours
- Do not turn the heat way up to "dry it out faster." High heat accelerates mould growth in saturated materials.
- Do not rip out wall materials or baseboards before the adjuster sees the damage in its original state.
- Do not throw out damaged contents — pile them in a documented inventory for the claim.
- Do not use bleach to "kill mould" on wet wall materials. Bleach is mostly water; it makes things worse.
- Do not wait until business hours to call your insurer or a restoration contractor. Every carrier has a 24/7 claims line.
- Do not sign anything from a contractor without reading it — especially Assignment of Benefits forms.
The hidden water you cannot see
A burst pipe rarely leaves all the water visible on the floor. Water migrates through:
- Wall cavities (capillary action up wall materials)
- Joist bays under flooring
- Insulation (which holds 10x its weight in water)
- HVAC ducts and registers
- Behind cabinets and built-ins
- Down through ceilings to the floor below
This is why DIY "mop and fan" cleanups fail. Surface water dries; hidden water rots framing and grows mould. Professional crews use thermal imaging and moisture meters to find every wet cavity.
What insurance typically covers
A sudden burst pipe is the textbook example of a covered loss on a standard Ontario homeowner policy. Coverage usually includes:
- Water extraction and structural drying
- Damaged wall materials, flooring, baseboards, and trim
- Damaged contents (subject to your contents limit)
- Additional Living Expenses (ALE) if you cannot stay in the home
- Plumber's cost to repair the failed pipe (varies by policy)
You will pay your policy terms (typically $500–$2,500). We bill the rest directly to your insurer in insurance-standard itemized documentation format.
After 24 hours: what to expect
- Days 1–3: Active extraction and demolition (if needed)
- Days 3–7: Structural drying with daily monitoring
- Days 7–10: Final dry standard confirmed; drying equipment removed
- Weeks 2–6: Reconstruction (wall materials, paint, flooring, trim)
For a typical kitchen or basement burst-pipe claim, plan on 4–6 weeks from burst to fully restored.

Frequently asked questions
- What should I do in the first hour after a burst pipe?
- Shut off the main water valve, cut power to affected circuits if water is near outlets or fixtures, open the lowest faucet to drain the lines, photograph everything before moving it, keep the failed pipe section, and call for emergency dispatch.
- Why keep the failed pipe or fitting?
- It is the proof of cause your insurer wants, and as a subrogation-certified contractor we preserve and log it so your carrier can pursue a responsible manufacturer or trade where one exists.
- Is burst pipe damage covered by insurance in Ontario?
- Sudden and accidental pipe failures are usually covered. Damage from freezing while the home was unheated or unattended, and gradual seepage, are commonly excluded — which is why documenting the timeline matters.
- How long will drying take?
- Three to five days for typical clean-water losses, longer for hardwood, plaster or insulated cavities. Drying ends when moisture readings match dry standard, verified daily.

About this guide & the team behind it
This article was written and reviewed by the PMII-certified restoration technicians at 24/7 Remedial Services, a Kingston, Ontario property-restoration company with more than two decades of combined field and construction experience across Eastern Ontario. We respond 24 hours a day, 7 days a week, 365 days a year to water, fire, smoke, mould, storm, and impact losses across Kingston, Napanee, Brockville, Gananoque, Picton, Belleville, Smiths Falls, Perth, Prescott, Carleton Place, and the surrounding Frontenac, Lennox & Addington, Leeds & Grenville, Lanark, Hastings, and Prince Edward county townships.
Every guide on this blog is grounded in the same industry standards Canadian insurance carriers expect on a properly documented claim file: the IICRC S500 standard for water damage restoration, the IICRC S520 mould standard for professional mould remediation, and industry-standard fire & smoke restoration practices for fire and smoke restoration. Where the article references a Category 1/2/3 water classification, a Class 1–4 drying environment, a Condition 1/2/3 indoor mould assessment, or a specific itemized line item, that terminology is used deliberately — it's the same vocabulary your adjuster uses and the same vocabulary that holds up in subrogation.
If you are dealing with an active loss as you read this, please do not wait. Most Kingston addresses see one of our restoration crews on-site within 60 minutes of dispatch — including overnight, on weekends, and during severe-weather events. Surrounding Eastern Ontario communities follow as quickly as travel allows. The cost of waiting on mitigation is almost always higher than the cost of acting immediately.
