WHAT WE DO

3 Ways We Fix Your Leak

Whatever it needs. One call handles it.

Leak Diagnosis

Diagnosed Right · Quoted Before We Fix

We work through it systematically. Checking the likely sources first, reading where the water's actually traveling from, and confirming the real cause before any wall, floor, or unit gets opened.

  • Methodical check of pipes, valves, fittings, and connections

  • Water traced to its actual source, not assumed

  • No unnecessary cutting or demolition

  • Clear explanation of what we found and why

  • Written upfront price before any repair work begins

Spot Repair

Priced Upfront · Diagnosed Right

Most leaks come down to one specific failure point. Whether it's a pinhole in a copper line, a cracked fitting, a corroded valve, a worn seal, a broken flange, a slow drip at a joint. Once we've found it, we repair just what's failed and confirm the rest of the system is sound. Clean fix, tested before we leave.

  • Pinholes, cracks, and failed joints repaired

  • Corroded or seized shutoff valves replaced

  • Worn fixture seals, gaskets, and flanges replaced

  • Surrounding pipe and connections checked to confirm they're sound

  • Tested and confirmed leak-free before we leave

  • Written upfront price before any work begins

  • Backed by our 12-month workmanship guarantee

Repiping

Priced Upfront · Built to Last

If we find corrosion, scattered pinholes, or pipe material that's simply past its years, patching one spot won't stop the next one from showing up. We'll show you exactly what we found and quote the repiping in writing before any work begins.

  • Honest assessment of whether repair or repiping makes sense

  • Aging or failing sections replaced with quality materials

  • Work planned to minimize disruption to walls, floors, and ceilings

  • Old pipe and debris removed and disposed of

  • Tested and confirmed leak-free before we leave

  • Written upfront price before any work begins

  • Backed by our 12-month workmanship guarantee

6 Reasons Why

Guelph Calls Jaytech

And why they stop looking after that first call.

"Jaytech took good care of us. They were very accommodating and I am very appreciative for their attention. Hard to find honorable people these days. These guys are honorable."

★★★★★ - Steve Garganis — Google Review of Jaytech Plumbing ✓

1. We Tell You What You Actually Need.

If it's one bad fitting or a worn seal, we'll fix that and stop there. We won't talk you into repiping a section that's perfectly sound, and we won't patch something that's clearly about to fail again. We'll show you what we find and let you decide.

2. Price Before We Touch Anything.

You get a written quote before a single tool comes out. The price you approve is the price on the invoice. No "it got complicated" surprises at the end.

3. Workmanship That Lasts.

Trained technicians, proper tools, no shortcuts. The difference between a quick patch and a repair that actually lasts, backed by an all inclusive 12-month warranty.

4. Same Visit. Job Done.

We want this off your mind. Jaytech is typically on-site the same day — often within a couple of hours of your call, and ready to repair whatever is causing you trouble.

5. Local to Guelph

No call-centre, no head office out of province. Just the local plumbers your neighbours already trust — still here, still answering the phone, year after year.

6. We Clean Up When We're Done

We sweep up, wipe down, and leave your home the way we found it except with quality plumbing. It sounds basic. You'd be surprised how rare it is.

QUESTIONS & ANSWERS

Leaks in Guelph — Common Questions

If yours isn't here, call us — we pick up.

There's water on my mechanical room floor and I have no idea where it's coming from. What now?

That's exactly what we're built for. A mechanical room puddle could be coming from a pipe, a valve, a fitting, a worn seal, or a connection point at the water heater or softener — and honestly, even an experienced eye sometimes needs to rule things out one at a time. We work through the likely sources methodically, find where the water is actually originating, and tell you clearly what we found before any repair begins.

Is it always a pipe that's leaking?

No — and that's a common assumption. Plenty of leaks come from a valve, a worn fixture seal or gasket, a cracked fitting, a failed tub or toilet flange, or a connection at an appliance like a water heater or softener rather than the pipe itself. If the leak turns out to be the water heater or softener unit failing internally rather than a connection point, that's a related but separate repair or replacement — we'll tell you plainly and point you to the right fix.

How do I know if it's a water line leak or a drain line leak?

Honestly, it can be hard to tell from the symptoms alone — both can cause water stains, damp spots, or a musty smell. One useful clue: a water line leak runs constantly, even when nothing in the house is in use, while a drain line leak only shows up when water is flowing through that specific fixture. If you're not sure, that's exactly what we're here to figure out — you don't need to diagnose it yourself before you call.

My pipe has a tiny pinhole leak. Is that a big deal?

Take it seriously, even though it looks minor. A pinhole leak is usually the result of corrosion working from the inside of the pipe outward — by the time you see it, the damage has already been developing for a while. If you have one pinhole leak, especially on copper pipe over 20 years old, there's a real chance others are forming nearby. We'll check the surrounding pipe and tell you honestly whether it's an isolated repair or a sign of more to come.

How do you decide between a spot repair and repiping?

It comes down to what we find when we get there. A single leak on pipe that's otherwise in good condition, with no other signs of corrosion or wear nearby, usually means a spot repair is all that's needed. Multiple leaks, scattered corrosion, or pipe material that's reached the end of its expected lifespan points toward repiping being the better long-term value. We explain what we found and quote both paths in writing — the decision is yours.

Can you find a leak I can't see or hear?

Most of the time, yes — and most water showing up where it shouldn't is a plumbing issue. But not always. Water stains and damp spots can also come from a roof leak, a clogged HVAC condensate line, a failed window or exterior seal, or in rare cases a foundation crack — and those aren't plumbing problems, even though they can look identical to one at first glance. What we bring is experience reading the pattern: where the water's showing up, when it appears, and what's above or near it, which usually tells us whether it's our problem to fix. If it's behind a wall or floor, finding it still means opening that section to confirm and repair it — we're not guessing from the outside, we're diagnosing as precisely as we can before we cut, then fixing what we find. If what we find points to a roof or HVAC issue instead, we'll tell you plainly so you can get the right specialist on it.

My water bill jumped and I don't see any leak. What's going on?

An unexplained jump in your water bill is one of the most common signs of a hidden leak — often one you'd never notice without checking. It could be a slow pinhole leak, a running toilet, a dripping valve, or a leak under a slab. We can help track down where the water is actually going.

Is a dripping shutoff valve something to worry about?

Yes, worth addressing rather than ignoring. A dripping or corroded shutoff valve usually means the internal seal has worn out, and it can get worse — sometimes failing completely when you need to shut the water off in an emergency. It's a straightforward fix, and a good one to take care of before you actually need that valve to work.

Leak Detection & Repair for Guelph's Homes

Guelph's mix of century homes, post-war bungalows, and newer builds means a wide range of pipe materials, fixtures, and mechanical equipment — and leaks don't all come from the same place. Older copper is prone to pinhole leaks from corrosion. Valves and fixture seals wear out with age. Flanges crack. Connections at a water heater or softener loosen over time. Whatever the source, the result looks the same from where you're standing: water somewhere it shouldn't be, and a homeowner who just wants to know what's happening and get it fixed.

We serve homeowners across Guelph, from Exhibition Park and The Ward to Kortright Hills, Westminster Woods, Hanlon Creek, and Stone Road. We're also who Kitchener, Cambridge, and Waterloo homeowners call when water shows up somewhere unexpected and they need someone to actually find the source, not just guess at it.

Jaytech answers the phone, gives you a real arrival time, and is usually there the same day. Written price before we start. Home left clean when we leave.
