A basement waterproofing project can take a day or more than two weeks to finish, depending on the type of service you need, the materials required to complete the job, and how easy it is to access the basement. Our experts can estimate the project’s duration during the free on-site consultation. Here are some average timelines for our services:
When designing your project, our team of waterproofing contractors will consider a number of factors – the location of the property, how much groundwater is in your area, the extent of water damage, your plans for the property, your budget, and more. Depending on these factors, we recommend the right basement waterproofing services.
Interior waterproofing is an effective way to deal with basement leaks from inside your home. Ideal for damp or wet basements, this method helps keep moisture out, stops mould and mildew from growing, and gets rid of musty smells. Whether your home is new or decades old, our Toronto interior waterproofing service offers a reliable fix to keep moisture out.
Our team will assess your basement and recommend the best interior drainage system, sump pump, and sealing options to stop leaks at the source. We handle everything from inspection to installation, keeping your basement dry.
Interior Waterproofing Cost – from $80+ per linear ft
Exterior waterproofing involves creating a durable, watertight barrier outside your foundation walls. Doing so prevents moisture from seeping into your building’s foundation and causing mould growth, structural damage, and other moisture-related problems.
Our contractors will excavate around the foundation, repair existing wall cracks, and install French drains to direct water away from your property.
Exterior Waterproofing Cost – from $100+ per linear ft
Installing a sump pump is one of the best ways to manage water that has already entered your basement. When the water level in the sump pit reaches a certain point, the device activates and then pumps the water out of the pit and away from the building.
We offer trusted sump pump installation, repair, and replacement services in Toronto. Whether you need a new pump for a new basement or want to upgrade your old one, the Aquamaster Waterproofing team has you covered.
Sump Pump Cost – from $700+ per system (depends on pump, installation and pit)
Protect your foundation from groundwater with a weeping tile system, also known as a drain tile system. These underground pipes collect and redirect groundwater away from your foundation to prevent your basement from flooding and experiencing water damage.
We can install the weeping tiles inside or outside the basement, depending on factors like the extent of the water problem, your budget, and the type of foundation. Our experts will walk you through your options so that you can make the best choice for your property.
Weeping Tile Installation Cost – from $30+ per linear ft

Window Well Installation Cost – from $1,800+ per well
Crawlspaces are prone to moisture, often leading to mould and mildew growth. We offer crawlspace encapsulation services, in which our team applies a moisture barrier to the crawlspace’s floors, walls, and sometimes ceilings and then installs a dehumidifier to circulate air and control humidity.
This helps prevent long-term structural issues caused by rot and water damage. Encapsulation also improves energy efficiency by reducing drafts and heat loss. Our technicians will inspect your crawlspace, recommend the right materials, and handle the full installation.
Crawlspace Encapsulation Cost – from $30+ per sq ft

Fixing cracks in your foundation can prevent costly future repairs and ensure your home is safe to occupy for many years. We provide internal and external solutions for repairing smaller foundation cracks, but we recommend combining both solutions for repairing foundation cracks wider than 3/16 inches.
We will assess the crack’s size, location, and cause before recommending the best approach. We offer epoxy injections, hydraulic cement, and exterior sealing to stop water from seeping in. Our goal is to fix the issue at its source and help protect your foundation from further damage and moisture intrusion.
Foundation Crack Repair Cost – inside from $600+, outside from $1800+
We offer basement underpinning services in Toronto to stabilize and strengthen weak building foundations and create additional living space or storage in your basement. Our team will excavate underneath the existing foundation and install concrete or steel beams to increase the foundation’s load-bearing capacity.
We also lower basement floors to boost ceiling height and make the space more functional. We handle permits, inspections, and all stages of construction for a smooth and safe upgrade. Consider underpinning if you’re planning to finish a basement or need better storage.
Basement Underpinning Cost – from $80+ per sq ft
Bench footing can increase the height of your basement, strengthen your home’s foundation, and provide access to foundation cracks. We’re highly experienced with bench footing in Toronto, providing everything necessary for a smooth and successful process. This includes excavation, bench-level construction, structural support installations, interior or exterior waterproofing, and insulation.
Bench footing is a great alternative to full underpinning when soil conditions or budgets call for a different approach. Our team follows all safety codes and engineering guidelines, and we always deliver long-lasting results that add value to your home.
Bench Footing Cost – from $100+ per linear ft
A walkout basement is an excellent investment if you want to increase your property’s value or even convert it into a rental with a separate entrance.

We handle everything from permits and design to excavation and final grading. Every walkout basement we build is safe, accessible, and fully integrated into your home’s structure. We also offer proper drainage and waterproofing so your new walkout basement stays dry and secure.

Egress windows are essential for basement safety and functionality, as they provide a secure exit during emergencies.

At Aquamaster, we specialize in professional egress window installations in Toronto and the GTA. Our services include precise wall cut-outs, proper drainage solutions, and waterproofing to ensure durability and code compliance. We offer free on-site estimates and special offers for new clients.

Protect your property from water damage and health hazards by installing a backwater valve. A backwater valve — also called a backflow prevention valve — automatically seals off your plumbing system, blocking wastewater from backing up into your home’s plumbing when there are floods or a blockage in the sewer system.
Our licensed plumbers will assess your setup, install the valve properly, and make sure that it meets Toronto city by-law standards. We also help with permit applications and inspections.
Backwater Valve Installation Cost – from $2200+ per installation
Water line repairs and replacement approaches include open trenching, trenchless pipe replacement, slip lining, and directional drilling. To determine the best approach, Aquamaster will consider multiple factors, including the waterline’s location, the surrounding vegetation and underground utilities, the project budget, and the condition of the existing waterline.
We prioritize methods that minimize disruption to your property. Our trenchless techniques, such as slip lining and directional drilling, allow for efficient repairs without extensive excavation, preserving your landscaping and reducing downtime.

There are several telltale signs that you may need to waterproof your basement, and recognizing those signs is the first step in preventing wet basement problems and frequent repairs. Here are some of the things to look out for:
There are several potential causes of water coming up from the basement floor, the most common being groundwater.
If the foundation wall or floor in your basement feels damp when you touch it, you may have a leak. In scenarios like this, our foundation waterproofing contractors will find and then fix the source of the leak before the problem escalates.
Tie rods hold together the form for foundation pouring. Once the tie rods are removed, a hole in the foundation may remain, providing a pathway for water to enter your basement.
High humidity is one sign that you may have a leaky basement. When moisture enters the foundation, humidity in your basement increases.
A musty odour may be a sign that mould or other fungi are growing in your basement. All fungi need moisture to flourish, so if you notice a stale smell in your basement, there’s likely a leak somewhere.
Water stains on your basement walls may be caused by water leaking from pipes, plumbing fixtures, or a crack in the foundation. This is a sign that you should contact professional waterproofing contractors to identify and fix the underlying problem.
Ideally, waterproofing should be used to prevent basement leaks before they happen, as opposed to leak detection and repair after they happen.

Benefits of internal waterproofing:
Overall, both internal and external waterproofing have benefits and can effectively prevent water damage to a building. The best approach will depend on the specific circumstances of the building and the severity of the water intrusion.

Our external basement waterproofing service involves the following steps:
Exterior and internal waterproofing are two methods of preventing water from entering a building structure, but they differ in terms of their location and application.
External waterproofing involves applying multiple layers of waterproofing materials outside a building’s foundation or walls, typically during the construction phase. This can involve excavating around the building to expose the foundation walls, cleaning the walls, and repairing any cracks. A membrane or coating is then applied to the walls, a drainage system is installed, and the trench is backfilled. External waterproofing is often considered to be a more effective method, as it prevents water from entering the structure in the first place.
On the other hand, internal waterproofing is done inside the building, usually in the basement or lower levels. This can include the installation of a sump pump, a French drain, or a waterproof membrane on the inside of the walls. While it can effectively manage water that has already entered the structure, it does not prevent water from entering the structure in the first place, which can lead to moisture buildup and potential mould or mildew growth.
Overall, external waterproofing is considered to be the more effective and comprehensive solution for preventing water damage to a building, but it can also be more expensive and disruptive to install. Internal waterproofing is often used as a secondary measure or a temporary solution until the walls can be protected from the outside.
