Do You Notice Water, Dampness, or Musty Odors in Your Basement?

Many North York homeowners face moisture issues in the basement due to cracks, porous concrete, or floor joints. 

AquaBoss installs waterproofing systems that address both sides of the problem. Interior solutions redirect water after it enters using sealed drainage and crack injections. Exterior systems stop groundwater at the source with membranes, drain boards, and weeping tile. Each setup is designed for North York’s clay-heavy soil, freeze-thaw cycles, and elevated water table.

Every system is designed to handle North York’s freeze-thaw cycles, clay soil, and various building structures—ensuring your basement remains dry, secure, and durable. If you notice moisture or musty smells, schedule a free inspection today.

Why North York Homeowners Trust Our Basement Waterproofing Company

Our licensed basement waterproofing technicians handle every job—no subcontractors involved. Each AquaBoss project is managed by our in-house team, trained to address North York's soil pressure, freeze-thaw cycles, and older foundation types. We hold WSIB certification, BBB accreditation, and full insurance to perform drainage, crack sealing, and structural repairs in accordance with the Ontario Building Code. All installations come with transferable warranties and documentation suitable for insurance claims, resale, and future renovations.

Foundation Repair & Structural Protection Services 

Our foundation repair services are designed to stabilize homes in North York with basement foundations that exhibit stress, cracks, or shifting. These problems often arise due to water infiltration, soil movement, or long-term settlement—especially in older North York homes constructed with block or unreinforced concrete. Common issues include bowing walls, vertical cracks, sloped floors, and heaving slabs. 

At AquaBoss, we address these using techniques such as epoxy injection, steel bracing, bench footings, or complete rebuilds when necessary. Before starting, we evaluate the foundation load, water pressure around the home, and soil movement. We then apply the appropriate long-term repair to prevent failure and safeguard your property’s value.

How much does basement waterproofing cost in North York?

In North York, the cost for basement waterproofing generally falls between $65 and $250 per linear foot. This depends on the chosen method, extent of damage, and foundation specifics.

This is particularly the case when dealing with deep foundations, sump pit installations, or structural repairs. 

At AquaBoss, we ensure transparent pricing and provide detailed estimates. Our costs cover materials, labor, and warranties, with no hidden fees or unexpected upsells. Just straightforward answers from the beginning.

Why Choose AquaBoss: We Offer the Best Basement Waterproofing Services in North York

Our Basement Waterproofing Process: Step-by-Step

At AquaBoss, we focus on basement waterproofing through a detailed, step-by-step process. Our aim is to stop current leaks and prevent future moisture issues. Each stage is managed by skilled AquaBoss experts. The process includes inspection, system design, professional installation, and a final walkthrough. We utilize proven systems that adhere to the Ontario Building Code.

Step 1: Initial Moisture Inspection & Free Estimate

Initially, a certified waterproofing expert conducts a comprehensive evaluation of foundation walls, floor joints, drainage points, and relative humidity. We look for cracks, stains, efflorescence, mold traces, and signs of sump failure. You receive a written estimate that outlines the scope, system type, pricing, and warranty details.

Step 2: Problem Diagnosis & Custom Plan

Next, we determine the root cause, which could be hydrostatic pressure, surface pooling, or weeping tile failure. We then align it with the right solution. Your plan will specify if interior systems like sump pumps or vapor barriers are necessary. Sometimes, exterior excavation is needed. The plan also details the project timeline and compliance steps.

Step 3: Exterior Excavation or Interior Prep

For exterior waterproofing, we excavate the foundation wall to reveal and clean the surface. For interior solutions, we remove floor sections along perimeter walls to install drainage channels and sump infrastructure. The method depends on site access, soil depth, and wall type.

Step 4: Sealing, Crack Repair & System Installation

We set up multi-layer protection systems, including waterproof sheeting, drainage panels, and vapor shields to block humidity. Cracks are sealed with high-pressure epoxy or polyurethane injections. Sump pits, backwater valves, French drains, and weeping tiles are installed according to your custom plan.

Step 5: Backfilling, Site Clean-Up & Final Walkthrough

Exterior trenches are backfilled with clean fill and gravel. Interior sections are sealed and restored using top-quality waterproofing materials. Our waterproofing team conducts a final system test. We then review the completed work and provide documentation, which is helpful for resale, insurance, or rebate programs.

Emergency Waterproofing & Post-Flood Response 

Immediate action is crucial when water damage strikes. Basement flooding, sump pump malfunctions, or foundation leaks demand swift intervention. These issues can lead to mold, shifting foundations, and costly repairs.
