Emergency: Your First 10 Minutes

Step 1

Turn off your main water valve

Turn the handle beside your water meter (front basement/crawlspace) clockwise. If seized, don’t force it—we can arrange a curb-stop shut-off at the property line. Condo/apartment: close the suite shut-off and notify building management.

Step 2

Kill power near standing water

Trip the breaker for the affected area if water is close to outlets, appliances, or the panel. Do not enter water that could be energised.

Step 3

Take a few photos for insurance

Pause laundry, dishwasher, showers, and flushing. During a sewer backup, reducing flow prevents the floor drain/toilets from rising.

Step 4

Quick prevention + documentation

Move rugs/furniture/boxes, lift electrical cords, place towels at doorways. Snap photos/video of: source, water path, and damaged areas—this helps with insurance and our diagnosis.

Step 5

Find the cleanout (if safe)

Locate the main cleanout (round or square cap on a vertical or floor pipe). Do not remove if pressure is high or you smell sewer gas—wait for our technician. We’ll open, clear, and camera-scope to verify the fix.

FAQs — Plumber in Grimsby

Yes. We serve Grimsby on the Lake, Grimsby Beach, Casablanca, Nelles, Dorchester Estates, and Grimsby Mountain most days. Call before early afternoon for the best chance of a same-day window on urgent issues like sewer backup, leaks/bursts, no hot water, or a blocked toilet. You’ll get a confirmed arrival window and an “on-the-way” text. Clear, upfront options are provided before any work begins.

Gurgling or sewer odours usually mean a partially blocked main or surcharge from the municipal line—common after heavy rain near the lake. Our fix is camera-first (to identify roots, grease, cracks, or bellies), then the right clear (auger/jet), and a prevention plan so it doesn’t return. Homes that experience surges repeatedly may benefit from a backwater valve to stop sewage from pushing into the home.

Stop all water use, keep kids/pets away, and do not flush. If safe, locate the main cleanout and remove any standing water nearby. We’ll open the cleanout, clear the obstruction, and camera-check for offsets, roots, or low spots so the repair lasts. Our free Sewer Backup First-Hour Checklist helps you limit damage and document everything for insurance while we’re on the way.

If you’ve had backups, frequent gurgling/odours, or live in a surge-prone area, a backwater valve is smart protection. We handle permit, installation, and inspection, then show you how to test the valve. Rebate programs change over time—use our Backwater Valve Rebate Checker to see current eligibility and amounts, and we’ll guide you through the paperwork.

Test monthly (lift the float and confirm discharge), clean the pit seasonally, and verify the check valve is working. Many lake-effect storms bring outages—add a battery backup sized for your pit and flow so you’re protected when the power goes out. Our Sump Pump Test & Backup Sizer estimates runtime and recommends a setup that suits your home.

We diagnose first. Consider age (many tanks reach end-of-life at 10–12 years), leaks vs. control faults, part availability, and your household’s hot-water demand. If repair makes sense, we fix it; if not, we can replace the tank the same day, remove the old unit, and set the new one to code. Use our Water Heater Repair-or-Replace Calculator before you decide.

Yes, we offer same-day drain cleaning. We prefer camera-first (or camera-after) so we can see whether the cause is roots, grease, scale, or a low spot. That lets us choose the right method (auger vs. jet) and prevents repeat clogs. You’ll receive the video and location/depth data for your records or a home sale.

Usually, yes. Most running toilets need a flapper, chain, or fill-valve rebuild; rocking or leaking bases often need a wax seal and new shut-off/supply line. If the toilet backs up along with a shower or floor drain, it may be a mainline issue—we’ll camera + clear to make sure the fix lasts. We stock common parts and can replace the toilet when that’s the better value.
