Drain Repair Services in Toronto

Whether it’s a cracked pipe, root intrusion, or collapsed drain line, our certified technicians diagnose the problem, expose the damaged section if needed, and implement permanent structural repairs.

Drain damage is one of the leading causes of basement leaks and water intrusion in Toronto homes. Left unresolved, it can overwhelm your waterproofing system, degrade your foundation, and trigger mold, odors, or slab shifting.

Our drain repair process combines camera scoping, high-accuracy diagnostics, and trench or trenchless methods depending on your site conditions. If your property includes a basement waterproofing system, we coordinate repairs to ensure that drainage function and membrane protection remain fully intact.

All work is performed in compliance with Toronto Plumbing Code and includes full post-repair verification. Whether you need floor drain pipe replacement, exterior storm drain repair, or basement branch line correction — Aquaboss restores your drainage system safely and permanently.

Common Types of Drain Repair We Perform

‍

Every property presents different drainage issues. At AquaBoss, we specialize in a variety of drain repair methods that match both the severity of the problem and the construction of your home’s basement waterproofing system.

1. Crack and Fracture Sealing in Drain Pipes

Older clay or cast iron pipes often develop stress fractures. These are sealed internally using epoxy lining or externally exposed for precision resealing.

2. Root Intrusion Removal and Pipe Replacement

Tree roots often enter through joints or gaps in underground pipes. We remove root systems with mechanical cutters, then replace compromised segments with root-resistant PVC.

3. Pipe Belly and Sag Correction

A drain belly refers to a sunken pipe section where water and debris collect. We correct this by regrading or replacing the segment with a properly sloped installation.

4. Leaking or Separated Joints

Disconnected joints in older drain systems lead to water escaping under the basement slab or around foundation walls. These are reconnected and sealed to restore airtight and watertight flow.

5. Drain Line Replacement After Waterproofing Failure

If poor drainage caused waterproofing system failure, such as a flooded sump basin or wet floor perimeter, we redesign the drain path and integrate with the new waterproofing layout.

Each repair approach is selected based on the exact issue, material of the existing pipe, and its relationship to the surrounding foundation and waterproofing infrastructure. Our goal is to permanently resolve drainage issues while maintaining the integrity of your basement waterproofing system.

Our Drain Repair Process: Step by Step

‍

At AquaBoss, every drain repair project begins with an in-depth assessment of pipe condition, water flow, and system compatibility with basement waterproofing infrastructure. We prioritize non-invasive techniques where possible, while ensuring code-compliant structural correction.

Step 1: Camera Inspection & Mapping

We begin with a high-definition sewer camera scope to locate cracks, root intrusions, or misaligned joints. Drainage flow is evaluated in real time to verify blockage points or flow disruptions.

Step 2: Damage Classification & Repair Planning

Once the footage is reviewed, we classify the problem as structural failure, flow disruption, or joint compromise. A repair plan is created based on slab elevation, site access, and interaction with any basement waterproofing zones.

Step 3: Localized or Full-Length Pipe Replacement

Depending on severity, we either replace the affected segment (spot repair) or install an entirely new PVC line. In finished basements, routing is adjusted to avoid damage to flooring or internal walls.

Step 4: Waterproofing Integration Check

If the drain line interacts with a waterproofing system—such as a sump discharge or interior French drain—we test those connection points and ensure routing integrity is restored. This prevents hydraulic pressure from being misdirected into dry areas.

Step 5: Final Flow Test & Site Restoration

We conduct a full post-repair flow test to verify unobstructed drainage. The trench is backfilled with compacted material, and all disrupted surfaces—such as concrete slab, flooring, or landscaping—are restored to pre-repair condition.

What Causes Drain Pipe Damage in Toronto Homes?

‍

Drainage systems in older Toronto homes often rely on clay, cast iron, or early-generation PVC — all of which are vulnerable to specific types of structural failure over time. Understanding the causes behind drain pipe damage allows for more accurate diagnosis and long-term repair planning.

The most common causes of drain damage include:

Pipe aging and material decay: Cast iron corrodes from the inside due to acidic waste and moisture, leading to scale buildup and eventual collapse.
Tree root intrusion: Roots can infiltrate joints in older clay or unsealed pipes, causing blockages or physical breakage.
Improper slope or ground settlement: Soil movement or subgrade erosion can create reverse slopes or disconnected sections.
Freeze-thaw cycles: In winter, water inside or around drain lines can freeze, causing cracks and stress fractures.
Heavy surface loading: Vehicle traffic or concrete work above shallow pipes can crush or offset drain lines, especially in garages and driveways.
Construction or renovation damage: Drains near underpinning work or bench footing installation may become cracked or misaligned.

Basement waterproofing systems — particularly those with interior drainage channels or sump-connected systems — can also be affected by broken or misdirected drain lines. When pipe damage interrupts the expected water flow path, pressure may build up in areas designed to remain dry.

Warning Signs You Need Drain Repair

Early warning signs of drain failure can appear subtle but often escalate quickly into serious water damage. In waterproofed basements, even minor drain issues can compromise moisture control and threaten the longevity of your system.

The symptoms below typically indicate issues like partial pipe collapse, root infiltration, disconnected joints, or deteriorated cast iron. Drain repairs in such cases involve pinpoint diagnostics using camera inspection followed by targeted excavation or pipe section replacement.

In homes with existing basement waterproofing, drain damage can overwhelm the system by rerouting water into unintended areas. Timely repair protects both your interior and your exterior waterproofing barriers.

Common symptoms that signal the need for professional drain repair include:

Persistent water pooling near basement walls or floor drains

Gurgling sounds from fixtures when other drains are in use

Strong sewer odors near basement utilities or unfinished floors or frequent backups in floor drains, even after cleaning

Water stains along the base of foundation walls or sudden soft spots in basement flooring or concrete cracks near drain lines

Why Timely Drain Repair Matters in Waterproofed Homes

Drainage problems aren’t isolated plumbing issues — they directly impact the performance and longevity of your basement waterproofing system. If damaged drains are left untreated, they can compromise sump pumps, weeping tiles, and even sealed foundation membranes.

A leaking drain under your basement slab may allow water to pool beneath your waterproofing barrier, leading to unseen hydrostatic pressure. In some homes, this pressure causes cracks, seepage, or complete failure of the internal waterproofing layer.

Similarly, a blocked or sagging drain near a foundation wall may reroute water against your exterior membrane, stressing the protective seal and allowing moisture infiltration.

Timely drain repair prevents:

Backup into finished basements
Foul odors and moisture buildup
Foundation erosion near the pipe outlet
Overloading of sump systems due to redirected runoff

At AquaBoss, drain repair is a core element of long-term basement protection. Whether your waterproofing system is newly installed or over a decade old, resolving drainage issues early helps preserve your foundation, control moisture levels, and extend system performance. As a leading waterproofing company in Toronto, we ensure that every repair strengthens drainage function and safeguards your basement from recurring water damage.

How Much Does Drain Repair Cost in Toronto?

Drain repair costs in Toronto can vary based on the type of issue, pipe location, and repair complexity. For interior drain line fixes such as clogged or cracked pipes behind a finished wall, the cost typically ranges from $450 to $1,200 depending on access and pipe length. Exterior drain repairs — especially those involving excavation or full line replacement — can range from $1,500 to $4,500 or more.

Several factors affect pricing:

Drain location – Interior repairs are usually less invasive than exterior trenching.
Pipe material and age – Replacing clay or corroded metal often costs more than PVC.
Depth and soil type – Deeper lines in compacted soil increase excavation labor.
Connection to waterproofing system – Drain repairs involving sump or weeping tile require precision integration.
