The Homeowners Whose Basements Stopped Leaking After Rain

Most basement leaks start underground, at a weeping tile that’s clogged, collapsed, or was never there. The homeowners who call us are tired of the same wet basement after every storm. These are the ones who finally stayed dry. Over 20 years, we’ve earned a 9.9 out of 10 on HomeStars across more than 800 reviews and protected more than 10,000 basements across the GTA.

Clean, Repair, Replace, Here's the Whole Job

The right fix depends on your pipe. We confirm its condition with a camera first, then handle whichever of these your home needs.

Exterior Weeping Tile Repair

This is the drain around the outside of your footing. When it clogs or breaks, water builds against the foundation and pushes through. We dig to the footing and fix the failed section.

Interior Weeping Tile Installation

For older Mississauga homes with no working drain, or where digging outside isn’t practical. We break out the perimeter floor, lay new pipe and stone, connect it to a sump pit, and seal the wall.

Clogged Weeping Tile Cleaning

Silt, soil, and tree roots choke a weeping tile until it stops draining. We find the blockage, clear it, and confirm flow — then tell you straight if it’s fixed or the pipe’s too far gone.

Weeping Tile Replacement

Old clay tile and crushed, root-invaded pipe can’t be cleaned back to life. When the line has collapsed, we replace it with new perforated pipe, fresh drainage stone, and a proper connection to your drain.

Foundation Drain Repair

Your weeping tile is only as good as where it drains to. We inspect and fix the connection to the sump pit or storm drain, so water actually leaves instead of pooling against the wall.

Sump Pit and Connection

A weeping tile needs somewhere to send the water. We install or connect a sump pit and pump in Mississauga so it discharges reliably, plus a battery backup so it keeps running when the power doesn’t.

What Are the Benefits of Weeping Tile Repair?

A drain that actually drains is the quiet foundation for everything you want from your basement. Here’s what it protects and unlocks:

  • Finish the basement — build a family room, office, or gym without water creeping back in after the next storm.
  • Add a legal apartment — a dry, drained basement is the base for a legal secondary suite where permitted.
  • Protect your foundation — moving groundwater away eases the pressure that cracks and shifts walls over time.
  • Store with confidence — keep furniture, electronics, and keepsakes safe from damp and mould.
  • Qualify for related rebates — weeping tile work often pairs with rebate-eligible sump pump and backwater valve installs.
  • Sell for more — a documented drainage system and transferable warranty reassure buyers at closing.

What You'll Pay for Weeping Tile Repair in Mississauga

Weeping tile is a see-it-to-quote-it job. The cost depends on whether the pipe is cleaned, repaired, or replaced, and whether the work is interior or exterior. Here’s a realistic guide.

ServicePrice Range (CAD)
Clogged weeping tile cleaning$400 – $1,200
Interior weeping tile installation$100 – $240 / linear ft
Exterior weeping tile repair$150 – $400 / linear ft
Weeping tile replacement (section)Quoted on inspection
Sump pit and pump connection$900 – $1,200+
Video camera drain inspectionIncluded with quote

All prices are approximate, based on standard residential conditions in Mississauga. We provide written quotes after a free on-site inspection — never over the phone or from photos, because pipe condition is only confirmed by camera or excavation.

The most common reason a quote comes in higher than expected? The camera finds the pipe is collapsed or root-invaded rather than simply clogged. Cleaning won’t fix a broken line, so we confirm the pipe’s condition on inspection and quote the right scope upfront.

What Is a Weeping Tile and How Does It Work?

A weeping tile is a perforated drainage pipe installed around the footing of your foundation. It collects groundwater and carries it off to a sump pit or storm drain. The holes let water in; the slope carries it away. It’s the single most important part of keeping a basement dry.

A working system has three parts: perforated pipe at the footing, a layer of clean drainage stone around it, and a connection that discharges the water somewhere safe. Most modern Mississauga homes have weeping tile inside under the slab and outside at the footing. Many older homes in established neighbourhoods have only the exterior line — or clay tile long past its life, which is exactly why they leak.

Roots, Clay Tile, and Why Drainage Fails

Failure is common in Mississauga’s older housing stock, where original clay tile and exterior-only systems are at the end of the line. The cause decides the fix.

  • Silt and soil clogging — fine particles wash in over the years and choke the pipe until water can't drain.
  • Tree root intrusion — the number-one cause of failure in mature Mississauga neighbourhoods like Port Credit and Lorne Park.
  • Collapsed or crushed pipe — old clay tile and thin pipe break under soil pressure and ground movement.
  • Age and clay tile — original weeping tile in older homes simply wears out and cracks apart.
  • Disconnection from the drain — the pipe exists but no longer connects to the sump or storm drain.
  • No interior system — common in older homes that never had interior weeping tile installed.
  • Hydrostatic pressure — saturated soil presses water straight through the wall once the drain fails.

If your basement leaks after every heavy rain and the exterior drain is old or clogged, the weeping tile is the cause. Sealing the wall inside without fixing the drain just moves the leak somewhere else.

Weeping Tile Cleaning vs. Repair vs. Replacement: How to Choose

Whether we clean, repair, or replace comes down to the pipe’s condition, its age, and whether a system exists at all.

Cleaning is the right call when the pipe is intact but blocked by silt or light roots, and a camera confirms the line is still sound once cleared.

Replacement is the right call when the pipe is collapsed, crushed, broken, or so root-invaded that clearing it won’t hold. Old clay tile almost always lands here.

New interior installation is needed when an older home has no working interior drain, the exterior line can’t be practically reached, or a finished basement needs a reliable interior system tied to a sump pit.

We make that call during the free inspection. We won’t sell you a full replacement when a cleaning will do, and we won’t clean a broken pipe and pretend it’s fixed.

Weeping Tile Questions, Answered Straight


A weeping tile is an underground drain pipe running around the bottom of your foundation. Small holes let groundwater in, then it carries that water off to a sump pit or storm drain so it never reaches your basement. When it clogs or breaks, water backs up against the wall and leaks in.

The clearest sign is a basement that leaks or stays damp after heavy rain, especially along the floor-wall joint. Slow drainage, pooling water outside near the foundation, and musty smells are other clues. The only way to know for sure is a video camera inspection.

It depends on the pipe. If it’s just clogged with silt or light roots and the pipe is still sound, we can clear it. If it’s collapsed, crushed, or full of roots — common with old clay tile — cleaning won’t last and it needs replacing. Our camera inspection tells us which one you’re dealing with before any work starts.

Exterior weeping tile runs around the outside of your footing and is the first line of defence. Interior weeping tile runs under the basement floor along the inside perimeter and drains to a sump pit. Many older Mississauga homes only have the exterior line — adding an interior system is often the fix for a chronically wet basement.

The pipe has small holes along it to let water in. Roots hunting for moisture find those holes and grow right into the pipe, eventually blocking it completely. It’s the most common cause of failure in established Mississauga neighbourhoods with mature trees.

Usually, yes. An interior weeping tile collects water under your floor and needs somewhere to send it — that’s the sump pit and pump. We connect the drain to the sump so the water is pumped safely away, and recommend a battery backup so it keeps running during a storm-related power outage.


You may. The City of Mississauga offers a basement flooding prevention rebate of up to $7,500 for approved work like sump pump and backwater valve installation, which often goes hand-in-hand with weeping tile work. One catch: as of February 12, 2025, the City must pre-approve the work before it’s installed. We handle the pre-approval and paperwork and walk you through eligibility. Amounts and rules change, so we confirm the current figures on inspection.

Yes. We come to your home and give you a free inspection and a written price, with no obligation, anywhere in Mississauga. We don’t quote weeping tile work over the phone, because we can only confirm whether the pipe is clogged or broken by inspecting it in person.
