Where Leaks Start
Common Water Leaks We Repair in Ajax
Sinks
Leak Under the Sink
Loose supply lines, worn faucet seals and leaking P-traps are the most common causes of a wet sink cabinet.
Pipes
Pipe Leaks & Sweating
Pinhole leaks, loose fittings and condensation on cold pipes in basements and utility rooms.
Valves
Leaking Shut-Off Valves
Older valves under sinks and toilets often drip once they are turned. We replace them with new quarter-turn valves.
Toilets
Toilet Leaks
Leaks at the base, tank bolts or supply line can soak the subfloor quietly. We reseal and secure the toilet.
Outdoor
Outdoor Tap Leaks
Drips from hose bibs and frost damage after winter. We repair or replace outdoor taps before the next freeze.
Appliances
Appliance Water Lines
Leaks from fridge water lines, dishwasher hoses and washing machine connections fixed and secured.
Signs You Have a Hidden Water Leak
Not every leak drips where you can see it, which is why good water leak repair starts with a little detective work. Watch for these warning signs in your Ajax home:
- A water bill that is higher than usual with no change in how you use water.
- Brown stains or bubbling paint on ceilings and walls.
- A musty smell under sinks or in the basement.
- Warped flooring or a soft spot near a toilet, tub or dishwasher.
- The sound of running water when every tap is off.
Quick meter check
Turn off every tap and appliance that uses water. Note the reading on your water meter, wait an hour without using any water, then check again. If the number has moved, you likely have a leak somewhere in the house.
What to Do Right Now If Water Is Leaking
- Shut off the water. Use the valve under the fixture, or the main shut-off if you can’t find the source.
- Turn off power to wet areas if water is near outlets or lights, and stay out of standing water.
- Soak up and protect. Use towels and buckets, and move belongings out of the way.
- Call us on (437) 476-0410. We are open 24/7 for urgent leaks.
If you have no water at all, or the leak seems to be at the street or the water meter, contact the Region of Durham first, since that part of the system is theirs. For everything inside your home, early water leak repair is always cheaper than fixing water damage later.

Where We Find Water Leaks Most Often in Ajax Homes
Water leak repair in Ajax and across Durham Region tends to come back to the same trouble spots:

- Kitchen sinks: loose supply lines, worn faucet seals and dishwasher connections.
- Bathrooms: toilet seals, vanity drains and old caulking around tubs and showers.
- Laundry rooms: washing machine hoses that crack with age.
- Basements and utility rooms: water heater fittings, shut-off valves and sweating cold-water pipes.
- Outside walls: hose bibs and pipes that freeze in January and February.
Checking these spots once or twice a year takes a few minutes and can save you from a costly repair. Not sure what you are looking at? We are happy to check them for you during any visit.
Water Leak Repair That Lasts
A quick wrap of tape might slow a drip, but it rarely lasts. Our water leak repair replaces the worn or damaged part, checks nearby connections for wear, and tests everything before we leave. Household leaks can waste thousands of litres of water a year, according to the EPA WaterSense program, so a proper fix pays for itself.
Preventing leaks in Ajax winters
Cold snaps are hard on outdoor taps and pipes along exterior walls. Shut off and drain outdoor taps in the fall, insulate exposed pipes in cold spots, and keep the heat on when you travel. A little prevention in the fall means less water leak repair in the spring. If you need help getting your home ready, our handyman services can take care of it.

FAQ
Water Leak Repair FAQs
What should I do first if I find a water leak?
Turn off the water at the nearest valve or at the main shut-off, keep away from water near electrical outlets, then call us on (437) 476-0410. We are open 24/7.
How do you find where a leak is coming from?
We trace the water back from where it shows up, check nearby supply lines, valves, drains and fixtures, and test connections until we find the source.
How much does water leak repair cost?
It depends on where the leak is, how easy it is to reach and the parts needed. We give you an upfront price before any work starts.
Can a small leak really cause damage?
Yes. Even a slow drip can soak into cabinets, subfloors and drywall over time, leading to rot and mould. Fixing it early is far cheaper.
Do you repair leaks outside Ajax?
Yes. We also offer water leak repair in Pickering, Whitby and Oshawa.
