    Toronto’s Own Waterproofing Team, as Seen on CTV News Toronto

    When CTV News Toronto looked at how homeowners can protect their basements from flooding, it turned to our team. That felt fitting. Aquatech has been based in Toronto since 1996, and the city’s older homes are where we learned the trade. Below is how the segment’s advice applies to the houses Torontonians actually live in.

    Spot the problem early

    The segment points to three warning signs: water stains, a musty smell, and white, chalky residue on concrete. In Toronto’s semi-detached and row houses, look along the shared wall too. Water can travel along a party wall from the house next door, so the stain on your side may not start on your property.

    Find the real cause

    Next, our team explained why every job starts with an inspection. A Victorian home with a brick or stone foundation lets water in very differently from a 1990s infill with poured concrete. Therefore, we trace the water to its actual entry point before recommending anything.

    Choose the right side

    The segment also shows that repairs can happen inside or outside. Downtown, many homes stand on narrow lots with tight side yards. In those cases, interior waterproofing often makes more sense than excavation. Where access allows, exterior waterproofing stops water before it reaches the wall.

    Understand the price

    Finally, our team covered what drives the cost: excavation depth, soil type, and anything in the way. In Toronto, that often means mutual driveways, porches, utility lines, and air conditioners squeezed beside the foundation. As a result, an on-site visit is the only way to get an honest number. Every project is backed by our lifetime warranty.

    How We Prevent Your Basement From Water Damage After Heavy Rain

    Play Video

    Your basement needs more care just as the ground that surrounds it. This is one of the main reasons that it easily gets soaked with rainwater.

    Some of the most common effects of heavy rain on your house include water leakage, wall cracks, foundation cracks, mould growth, moisture, dampness, and withering of the furnishings and floor in the basement area.

    Many of these issues often emerge due to the water pressure during heavy downpours.

    How Heavy Rain Affects Your Home

    • Heavy, persistent rain can saturate the soil and thus create hydrostatic pressure in it. This pressure is responsible for the moisture and water seepage into your basement through walls and floors.
    • Soil surrounds your basement foundation, as it is below the ground level. The looser the soil content is, the more it can absorb the rainwater. The soaked soil expands and thus creates lateral pressure, which deforms the basement foundation. This also results in leaky basement problems.
    • During heavy rain, your window well can get filled with water. This can also cause water leakage problems in your basement. Your drain can also get clogged with rainwater and can lead to water seeping from the walls in your basement.

    Cost Of Basement Water Damage RepairIn Toronto

    In Toronto, exterior waterproofing runs $110 to $500 per linear foot, with full project costs typically ranging between $2,000 and $27,000 depending on the size of the area, the extent of damage, and the complexity of the work. Interior waterproofing costs less upfront at $69 to $190 per linear foot, since it skips excavation entirely, though exterior work provides longer-lasting protection, particularly valuable given how much pressure Toronto’s spring thaw puts on aging foundations across the city’s six former municipalities.

    A sump pump installation typically runs $550 to $3,650, and a backwater valve ranges from $1,500 to $3,000, an upgrade worth pairing with the City of Toronto’s Basement Flooding Protection Subsidy of up to $6,650. A free on-site estimate is still the only way to get a number specific to your property.

    Warning Signs Of Water Damage In Your Toronto Home

    Water damage rarely announces itself all at once, it shows up as small, easy-to-miss signals first: damp spots, a musty smell, unexplained humidity, or a crack that wasn’t there last year. Catching these early is the difference between a straightforward repair and one that’s had time to spread into structural damage.

    Wall cracks

    If there are any minor or major wall cracks in the basement foundation, you must immediately get to the roots of it. The obvious reason for these cracks can be the water damage in the basement, which needs to be addressed as quickly as possible.

    Peeling paint and flaking drylock masonry coating on a concrete foundation wall from hydrostatic moisture pressure

    Humidity

    Moisture and humidity are other major concerns after water damage in your basement. You will feel the mist presence in the surrounding area with an awful smell. This shows the faulty airflow level and water damage sign in your basement.

    Aquatech Waterproofing — Foundation Crack Injection Repair

    Moldy smell

    Water damage in your basement can cause fungi infestation in the area. Molds and mildews can commonly occur if the surface is damp and has no sunlight source. These molds can be a very terrible sight with a foul smell. If ignored, they can increase at a quick rate.

    Damp, dark spots

    Your ceiling can have traces of discoloration. The discoloration can occur in the interior and exterior walls of your basement.

    Person testing for structural movement or bowing along a basement foundation wall

    Warped or buckling floors

    Water that’s found its way beneath your basement flooring can cause boards to warp, tiles to lift, or laminate to buckle at the seams. This kind of damage rarely stays contained to one small area, once moisture gets underneath flooring, it tends to spread outward until the source is actually addressed.

    Water accumulation

    If there is water damage in your basement foundation, you will often notice leakage from pipelines. This can cause the water to gather in your basement and add to the moisture and humidity, which can promote mold growth.

    Our Water Damage Repair Process In Toronto

    We Look Before We Talk Numbers:

    A licensed technician walks your Toronto property first, no phone estimate, no guessing from a photo. We trace whatever’s happening back to its actual cause, whether that’s spring hydrostatic pressure, a sewer system that’s simply aged out, or a foundation crack that’s been building for years. This part is free, and nothing gets sold to you on the spot.

    The Plan Goes On Paper First:

    Before any work starts, you get a written agreement spelling out the method, the price, and the timeline. Interior waterproofing, exterior work, a new sump pump, whatever the job is, there’s nothing vague left to discover partway through.

    Then We Build It To Last:

    Our crew installs commercial-grade materials, including the Aqua-Bloc membrane system, calibrated for what Toronto’s spring melt actually puts a foundation through. The finished job carries a lifetime warranty, protection that outlasts the invoice by decades.

    Lost Rivers and an Ancient Shoreline: The Water Beneath Toronto

    Toronto hides much of its water underground. In the 1800s and early 1900s, the city buried many of its creeks in sewers as it grew. Garrison Creek once wound through the west end, and Taddle Creek ran across what is now the University of Toronto campus. Today, streets and houses cover their old valleys.

    However, burying a creek doesn’t remove the water. Groundwater still follows those old valleys, so homes built over filled ravines often deal with damp basements their neighbours never see.

    The city also sits on the bed of a much older lake. About 12,000 years ago, glacial Lake Iroquois stood far higher than Lake Ontario does today. Davenport Road follows part of its old shoreline. Below that line, much of downtown rests on sand and silt left by the ancient lake. Above it, the ground turns to denser clay. As a result, water behaves differently from one neighbourhood to the next. Our guide to hydrostatic pressure explains how that buried water pushes against foundations.

    Many older Toronto homes also connect to aging sewer lines. During heavy storms, those lines can overload and push water back into basements. For that reason, a backwater valve is one of the most valuable upgrades a Toronto homeowner can make.

    Professional Foundation Repair Toronto

    Toronto’s spring thaw is brutal on a foundation, and the timing tells the real story: a hairline crack that sat quiet through January often turns into an active leak by April, once accumulated snowmelt saturates the soil and builds real pressure against your walls. We don’t just seal the crack you can see, we figure out whether it’s structural or purely cosmetic first, since the wrong call means paying for either too little repair or far more than the problem actually calls for. Depending on what we find, the fix might be interior drainage, an exterior membrane system, or targeted structural reinforcement.

    Wet Basement Repair Toronto Homeowners Trust

    By the time a Toronto basement floods, the actual cause usually isn’t a mystery, it’s several things that were building for months. A gutter that clogged last fall, weeping tile that’s quietly failed over the years, a crack that finally gave way once the spring thaw put real pressure behind it. Each one looks manageable alone, but together they’re what turns a damp corner into standing water on the floor.

    Rather than treating whichever symptom shows up first, we trace every contributing factor before recommending a fix. Every repair carries a lifetime warranty, regardless of how many separate issues turn up.

    Advanced Leaky Basement Repair Toronto

    The water you can see rarely marks where it actually got in. It could be a cove joint that’s finally given out, hydrostatic pressure building against a wall you’d never suspect, or a hairline crack that’s widened just enough to let water through. Patch the visible spot and skip the diagnosis, and the same leak just resurfaces somewhere else once Toronto’s next storm rolls through.

    Worth paying attention to before it becomes obvious:

    • A musty smell that returns no matter how much you ventilate
    • Chalky, white deposits forming on basement walls
    • Damp patches showing up with no visible crack nearby
    • Water actually pooling on the floor after heavy rain or spring melt

      My basement sump pump room wall just below my outside stairs and veranda were wet when we had more than 1 inch of rain. I called Aquatech Basement Waterproofing, and assigned Eric to meet me and assessed the work to be done and provided a very reasonable quote, and the work was scheduled to meet my schedule. There were 2 crews of 2 men all from Ukraine, all very knowledgeable, professional and did a wonderful job. They protected the flooring from the my main doorway right down to the basement room where the work was being done. The first 2 man crew removed the Styrofoam from that was on the basement walls and ceiling, moved my battery backup sump pump and moved to a safe locatiion while working in a small area. They broke the concrete floor around the room down to the footings, which needed to be to add weeping tile. They cleaned the area as they worked, removed the concrete debris and then brought in the required material to install weeping tile. The second crew assisted with the installation of the waterproof membrane on the walls, install the weeping tile and cementing of the part of the floor where the weeping tile was installed and added to the sump pump basin. They reinstalled the light and light switch, wall plug outlet. This all was done in a few hours. I would highly recommend Aquatech as their staff are very knowledgeable and very efficient in doing their job. I would definitely use them again if I have any future for any basement Waterproofing, or water issues. Thank you so very much Dianne P. The were very professional s advised that I ca Eric came by promptly, assessed the situation, gave me a quote, very reasonable and scheduled

      Thanks to Andrew, Will, Vasyl, and Yuriy of Aquatech Waterproofing, I no longer panic when the weather forecast calls for rain. The four-man team applied interior waterproofing to a large portion of my basement in less than seven hours. They placed Dimpleboard on the walls, installed and covered new four-inch plastic weeping tile pipe and also backfilled, cleaned and cemented the entire work area. The crew was courteous, on time and professional. Company representative, Nico, who appraised the job before the work began, was also very knowledgeable and kindly answered all my questions. The cost was extremely reasonable and I have a transferable life-time warranty for their services. I highly recommend them.

      Aquatech Project Consultant Richard responded ultra-quickly to my call for an estimate on 2 cracks on the inside of my basement foundation wall, visible only after I removed panelling & insulation & only when it rained heavily & water was pouring through those 2 small cracks. Richard impressed me with his assessment expertise & the speed at which he provided the best quote & solution for my leaks & my budget as a retiree on a fixed income. The repair on the outside wall with weeping tile replacement & utilities locates was scheduled & communication with Rita in the office & follow up with Richard was excellent. The day of the repair, Water Proof Technicians Vasyl & Yuriy arrived on time & ready to work. They were totally professional, polite & prepared with expertise & the right equipment to complete the task. They impressed me to no end with their work ethic & support for each other rotating in & out of the trench to get down to the footings. They installed the new weeping tile, cleaned the foundation wall & revealed 2 very long cracks which they V cut and repaired with hydraulic concrete. The rest of the process was their standard applications of Aqua Block, fibreglass mesh, another layer of Aqua Block, a layer of Poly-tarp, & a Dimpleboard membrane installation. They back filled the trench & cleaned up the area to perfection. Aquatech is blessed to have Vasyl & Yuriy as employees – thorough & meticulous. They are 12 out of 10 in my opinion!!! Note: 2 of my neighbours were impressed & asked for Aquatech’s phone number from me. Thank you Richard, Rita, Vasyl & Yuri.

      Aquatech consultant, Shawn McGirr, investigated my water problem and provided a realistic and cost effective solution. A few days later Bob and Alex arrived to do the work. They both worked very hard and were efficient and clean. They completed an incredible amount of work in a very short period of time and left the worksite as clean as it was before they arrived. I’m confident that the issue has been resolved and comforted by the lifetime warranty.

      Alex, Eugene, Mike and Igor did an amazing job with my basement waterproofing project. They were very personable, very hardworking and very efficient. I was very pleasantly surprised how quickly they finished the job. Everything was cleaned up and put back in order when they were done. I definitely recommend Aquatech Waterproofing. From my first meeting with Tony to discuss the project, I could tell they were the right choice

    Is Waterproofing Your Basement Worth It?

    Yes, and water damage prevention almost always costs less than the alternative. A small crack sealed early runs a few hundred dollars. The same crack left untreated through a few more freeze-thaw cycles can widen into a structural repair costing thousands more, and mould doesn’t stay contained once it takes hold, it spreads into framing and drywall, turning a manageable fix into something far more involved.

    Effective water damage prevention in Toronto means addressing the actual cause, whether that’s hydrostatic pressure, failing drainage, or a foundation crack, before it escalates. There’s also a resale angle worth considering: a documented, transferable warranty tends to come up during a home inspection either way, and buyers generally see proof of proper waterproofing as a point in the property’s favour, not something to negotiate down. Waiting rarely saves money, it just delays a bigger bill.

    Protecting Homes Across Every TorontoNeighborhood

    Toronto’s older core neighbourhoods each carry a different foundation story, shaped by when they were built and how close they sit to the lake, a ravine, or the water table underneath.

    The Beaches, running along the Lake Ontario shoreline, has some of the highest water tables in the old city, and many of its homes date to the early 1900s, well before modern waterproofing standards existed.

    Rosedale and Forest Hill, among Toronto’s oldest and most established neighbourhoods, are known for century-plus homes with original foundations that have had decades to settle, sometimes unevenly.

    Cabbagetown, one of the largest continuous Victorian neighbourhoods in North America, shares that same heritage-foundation story, character and age going hand in hand.

    The Annex and Yorkville, dense with Victorian and early-20th-century housing, sit close enough together that foundation age varies block to block rather than by broad area.

    High Park and Bloor West Village, adjacent to the ravine system running through High Park itself, deal with drainage patterns shaped by that green space nearby.

    The Junction, a former industrial hub with working-class housing from the early 1900s, and Leslieville and Riverdale, similarly aged residential streets east of downtown, round out some of the city’s most foundation-diverse pockets.

    Liberty Village and King West, by contrast, are newer, built largely on redeveloped industrial land, different foundation considerations entirely from the century-old homes just a few kilometres away.

    Wherever you’re located in Toronto, from a Victorian home in Cabbagetown to a newer build in Liberty Village, Aquatech brings the same standard of diagnosis, materials, and workmanship, backed by a lifetime warranty on every job.

    FAQs About Basement Waterproofing

    What basement waterproofing services does Aquatech offer in Toronto?
    Aquatech offers interior and exterior waterproofing, foundation crack repair, sump pump installation, drainage systems, and basement underpinning, all customized to your home’s specific needs. Services range from interior sealants to full exterior drainage systems, with certified contractors trained to handle everything from minor leaks to major structural damage.
    Water is coming in and my appointment is days away. What should I do?
    Don’t panic: a day or two of seepage rarely causes lasting damage. Take photos and videos in case it dries before the visit, move valuables off the floor, and call a restoration company if there’s standing water to dry out. There’s no need to tear out drywall for the technician.
    The insurance restoration crew already opened my walls. Should I book you now?
    Yes, this is the ideal time. Open walls let the technician see exactly where the water got in. Don’t remove anything more for our visit. Just show us where the water appeared, and you’ll get the cause and a quote in a single visit.
    Can I get a quote on a Toronto house I'm buying?
    Yes. Buyers and realtors book free, no-obligation estimates with us during inspection conditions all the time. You’ll know the cause of any leak and the cost to fix it before you firm up. It’s a waterproofing quote, so pair it with a full home inspection.
    Can you check several units in my condo or rental building?
    Yes. Tell us how many units need inspecting when you book, so we can schedule enough time. The technician calls ahead and meets you at the first unit.
    Is Aquatech a certified and reliable waterproofing contractor?
    Yes. Our contractors are trained and certified to handle a wide range of foundation and basement repair issues, and the company is fully insured. The business holds a City of Toronto license number T85-4304413.
    What are the best waterproofing companies in Toronto that offer a long-term warranty?
    Aquatech offers a lifetime waterproofing warranty, so confident in our exterior system that we guarantee the work for as long as you own the home. The warranty is transferable to all subsequent owners at no charge.
    Does Aquatech have experience with older Toronto homes?
    Absolutely. Regardless of the age of your home, Aquatech can provide the necessary waterproofing solutions, with technicians experienced in diagnosing issues in older foundations across the GTA.
    What basement waterproofing products are you using?
    We use waterproof membranes, hydraulic cement, polyurethane crack injections, interior drainage tiles, sump pump systems, and dimple board sheeting. Product choice depends on whether the solution is interior or exterior and the severity of the moisture issue.
    How is wet basement repair done in Toronto homes?
    Wet basement repair in Toronto typically starts with identifying the water source, whether it’s a foundation crack, poor drainage, or hydrostatic pressure. Technicians then apply the appropriate fix: crack injection, interior weeping tile installation, or full exterior waterproofing, depending on severity.
    What are Aquatech's Google ratings, services, and warranty coverage?
    Aquatech Waterproofing is rated 4.8 from customer reviews on TrustedPros. We offer interior and exterior waterproofing, foundation repair, sump pump installation, and drainage solutions, all backed by a lifetime warranty, with 24/7 emergency service and a price match guarantee.
    Does Aquatech offer emergency service for a leaky basement?
    Yes. Aquatech Waterproofing offers 24/7 emergency services across Toronto for wet basement repairs, flood control, and foundation leaks.
    What is exterior foundation waterproofing and when do I need it?
    Exterior foundation waterproofing is the process of excavating around your home’s foundation to apply waterproof membranes, repair cracks, and improve drainage. It’s the most permanent solution when water is penetrating your foundation walls from outside.
    What causes basement leaks and how are they repaired?
    Basement leaks are most commonly caused by foundation cracks, failed window wells, poor grading, or overwhelmed drainage systems. Repairs range from targeted crack injection for minor leaks to full interior or exterior waterproofing systems for chronic water intrusion.
    How much does foundation waterproofing cost?
    Foundation waterproofing cost depends on the method used. Interior solutions typically run $69–$195 per linear foot, while exterior waterproofing ranges from $100–$290 per linear foot. Most Toronto homeowners invest between $5,000 and $15,000 for a complete system, depending on foundation size and condition.
    Is there a basement flooding rebate available in Toronto?
    Yes. As of May 2026, the City of Toronto’s Basement Flooding Protection Subsidy Program offers up to $6,650 per property, covering backwater valves, sump pumps, battery backups, and home plumbing assessments. Work completed on or after November 12, 2025 qualifies.
    Do I need a permit for basement waterproofing in Toronto?
    Structural work like underpinning typically requires a City of Toronto permit. Simpler fixes, like interior crack injection or a sump pump swap, usually don’t.
    What's the difference between interior and exterior waterproofing?
    Interior waterproofing manages water after it reaches your foundation wall, routing it to a sump pump. Exterior waterproofing stops water before it gets that far, sealing the wall from outside.
    Do I need to pay anything before the work begins?
    No. The estimate is free, there’s no deposit, and nothing is due until the job is finished. Take your time with the quote and decide when you’re ready. Call 289-277-7974 or book online.
