Common Leak Repair Issues in Ontario Homes

Leaking Faucets:
 Worn cartridges and washers are common — especially in homes with older fixtures or hard water.

Toilet Leaks:
 Base leaks are often misdiagnosed. We check everything from flange to wax seal.

Pinhole Copper Leaks:
 These often happen due to acidic water or electrolysis — frequent in well systems around North Bay and rural Simcoe County.

Ceiling or Wall Dampness?
 Could be a hidden supply line or slow drain leak. We’ll scope it before cutting drywall.

Transparent Quote

You’ll get a written quote before any work begins. No surprises. No upcharges.
Step 3

Permanent Repair

We cut out the problem section and replace it with high-quality copper or PEX, using solder or ProPress — never SharkBite or push-fit fittings.

Frequently Asked Questions

How do I know if I have a hidden leak?

Check your water meter before and after a 2-hour no-use window. If it moves, you’ve got a leak.

Can you repair leaks without cutting drywall?

Yes — we use non-invasive tools to confirm location. If we must cut, it’s minimal and clean.

Are small leaks worth fixing?

Absolutely. A dripping faucet can waste over 3,000 litres a year — and often signals deeper issues.

Do you use SharkBite fittings?

Never. We only use soldered or ProPress joints with copper or PEX. No shortcuts. Ever.
