Quick checks before you call

No hot water

Check that the breaker hasn’t tripped (electric tank), the gas valve is fully open (gas tank), and the pilot is lit if it’s an older unit. If you smell gas or burning, don’t relight anything. Leave the home and call us.

Single sink clogged

Try a plunger on the affected sink only. Avoid chemical drain cleaners, especially in older downtown Niagara Falls homes with cast iron stacks or galvanized piping. Chemicals can accelerate corrosion in aging metal lines.

Toilet keeps backing up

Stop flushing. Remove visible items from the bowl and try a plunger. If other drains in the house are slow too, it’s likely a main sewer line issue, not just the toilet. Call us before it backs up further.

Water on the basement floor

Check the source: floor drain, sump pit, or around the water heater. If sewage is present or you can’t identify the source, keep kids and pets away from the area and call 905-928-6831 right away.

What to Expect

1

Arrival window & text updates

We confirm a short arrival window and text you when we’re on the way. Same-day plumbing visits are often available in Niagara Falls and nearby neighbourhoods for urgent leaks, clogs, and no-water calls.

2

Floor protection & safe set-up

Shoes covered, mats down, tidy work area. We protect floors and finished spaces, locate shut-offs, and make the area safe before we open any pipes or fixtures.

3

Diagnose the real cause

We don’t just clear symptoms. Your plumber checks visible piping, fixtures, drains, and water pressure so we know if it’s a local blockage, a failing part, or a bigger issue in the main line.

4

CLEAR PRICING BEFORE ANY WORK

You get a written installed scope and price range up front. No surprise “Niagara travel fee,” no open-ended hourly clock—just options that fit your home and budget.

5

SAME-DAY REPAIRS WHEN POSSIBLE

Common parts for Niagara Falls homes—traps, shut-off valves, supply lines, wax rings, cartridges, and drain cables—are on the truck. In many cases we can complete the repair in one visit.

6

VERIFY EVERYTHING & CLEAN UP

We run taps, flush toilets, test drains, and check for leaks or drips before we leave. Then we wipe down the area, remove debris, and review simple checks you can do after we’re gone.

7

Permits & code compliance

If the job needs permits, backwater protection, or other code upgrades, we explain why and handle the steps with the City so the work and any inspection are done to Ontario plumbing standards.
