Best Basement Waterproofing Company in Kitchener - Leaky Basement Repair

AquaBoss offers expert basement waterproofing services in Kitchener to eliminate leaks, prevent mold growth, and safeguard foundations from structural harm.

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

Many homes in Kitchener experience basement moisture due to water entering through foundation cracks, porous walls, or floor joints. This often leads to mold, musty air, and hidden structural damage. Interior systems redirect water after it enters using drainage channels, sump pits, and sealants. Exterior systems block groundwater before it reaches the basement by applying waterproof membranes, drain boards, and weeping tile around the foundation.

Each system is tailored for Kitchener’s high water table, clay soil, and freeze–thaw cycles. If you've noticed signs of moisture, book a free inspection today.

At AquaBoss, we install complete basement waterproofing systems in Kitchener to solve or prevent these issues. Each system is designed to handle Kitchener’s freeze-thaw cycles, clay soil, and varied building structures—ensuring a dry, secure, and durable basement.

Why Kitchener Homeowners Trust Our Basement Waterproofing Company

Licensed basement waterproofing technicians carry out all services—not subcontractors. Every AquaBoss project is managed by an in-house team trained to handle Kitchener’s soil pressure, freeze-thaw cycles, and aging foundation types. We are WSIB-certified, BBB-accredited, and fully insured to conduct drainage, crack sealing, and structural repairs in accordance with the Ontario Building Code. Each installation comes with transferable warranties and documentation valid for insurance claims, resale, and future renovations.

Foundation Repair & Structural Protection Services

Foundation repair services are essential for stabilizing homes with basement foundations that exhibit stress, cracks, or shifting. These issues frequently arise due to water infiltration, soil movement, or long-term settlement—particularly in older Kitchener homes constructed with block or unreinforced concrete. Common challenges include bowing walls, vertical cracks, sloped floors, and heaving slabs.

At AquaBoss, we address these with solutions such as epoxy injection, steel bracing, bench footings, or complete rebuilds when necessary. We start by evaluating the load on the foundation, the water pressure around the home, and soil movement. Then, we implement the appropriate long-term repair to prevent failure and safeguard your property’s value.

How much does basement waterproofing cost in Kitchener?

In Kitchener, basement waterproofing expenses generally range from $65 to $250 per linear foot, influenced by the chosen method, extent of damage, and foundation conditions.

This is particularly the case when deep foundations, sump pit installations, or structural repairs are part of the project. 

At AquaBoss, we ensure transparent pricing and provide detailed estimates. All costs encompass materials, labor, and warranties. No hidden fees. No unexpected upsells. Just straightforward answers from the beginning.

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

Aquaboss delivers expert basement waterproofing and foundation repair with lasting results. Our team provides proven solutions, quality materials, and reliable service to homeowners in Toronto and the GTA.

Our Basement Waterproofing Process: Step-by-Step

At AquaBoss, we excel in basement waterproofing through a detailed, step-by-step approach. Our aim is to address existing leaks and prevent future moisture issues. Each stage is managed by skilled AquaBoss professionals. These stages include inspection, system design, expert installation, and a final review. We utilize proven systems that comply with the Ontario Building Code.

Step 1: Initial Moisture Inspection & Free Estimate

In the initial step, a certified waterproofing expert conducts a comprehensive evaluation of foundation walls, floor joints, drainage points, and humidity levels. We inspect for cracks, stains, efflorescence, mold signs, and sump pump issues. You'll receive a written estimate outlining the scope, system type, pricing, and warranty details.

Step 2: Problem Diagnosis & Custom Plan

Next, we determine the underlying cause, whether it's hydrostatic pressure, surface pooling, or weeping tile failure. We then align it with the suitable solution. Your plan specifies if interior systems like sump pumps or vapor barriers are necessary. Sometimes, exterior excavation is needed. The plan also covers project timeline and compliance measures.

Step 3: Exterior Excavation or Interior Prep

For exterior waterproofing, we excavate the foundation wall to expose and clean the surface. For interior solutions, we remove floor sections along perimeter walls, allowing us to install drainage channels and sump systems. The method is based on site access, soil depth, and wall type.

Step 4: Sealing, Crack Repair & System Installation

We implement multi-layer protection systems, including waterproof sheeting, drainage panels, and vapor shields to block humidity. Cracks are sealed using high-pressure epoxy or polyurethane injection. 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 team of waterproofing contractors conducts a final system test. We then review the completed project and provide documentation, which is beneficial for resale, insurance, or rebate programs.

Emergency Waterproofing & Post-Flood Response

Immediate action is crucial when dealing with sudden water damage. Basement flooding, sump pump malfunctions, or foundation leaks demand swift intervention. These issues can lead to mold growth, foundation shifts, and costly repairs. 

AquaBoss offers same-day emergency waterproofing services throughout Kitchener and the surrounding areas. Our certified teams arrive equipped with high-capacity pumps, dehumidifiers, sealants, and backup systems to stabilize your property. We provide documentation for emergency work that complies with the Ontario Building Code and supports insurance claims and real estate disclosures.
