Basement Waterproofing Options & Details

What is Included in Basement Waterproofing Services Richmond Hill?

Example of Exterior Basement Waterproofing Project in Toronto, near CN Tower

Exterior waterproofing helps prevent water from entering the basement by shielding foundation walls with a waterproof membrane. This process involves excavation around the foundation walls to expose the exterior walls and allow access to the surface. The walls are then cleaned and prepared for the application of waterproofing membranes and other materials. This create a barrier against water penetration and prevents water from entering the basement through the walls.

Exterior Waterproofing Cost - $100-$300/linear foot

Sump Pump Installation and Battery Backup Replacement Example

A sump pump is a device that is installed in a basement or crawlspace to prevent flooding and water damage by removing excess water from the area. The pump is typically installed in a pit or basin, called a sump pit, which collects water that has accumulated in the basement or crawlspace.

When the water level in the sump pit rises to a certain level, the sump pump is activated and begins to pump the water out of the pit and away from the home's foundation through a discharge pipe. The pump is typically powered by electricity and is equipped with a float switch or sensor that automatically turns the pump on and off as needed.

Sump Pump Installation Cost - $500-$3,600

Waterproofing Contractor Installing a Window Well

Window well installation refers to the process of creating a secure and functional enclosure around basement windows or below-grade windows that are partially or fully below ground level. Window wells serve multiple purposes, including providing natural light, ventilation, emergency exits, and access for maintenance and escape.

Window Well Installation Cost - $1,600-$4,000

Plumbing Rough Ins Installed in the Basement

Plumbing rough-ins are an essential part of new construction projects. Plumbing rough-ins refer to the initial stages of plumbing installation that occur before walls, floors, and other structural elements are completed. They involve setting up the basic framework of plumbing systems within a building. This includes installing water supply lines, drainage pipes, vent pipes, and any necessary fixtures before the walls are closed up.

Example of Interior Basement Waterproofing Project

Interior waterproofing manages the water that makes it to your basements. This is normally done by installing waterproofing membranes, drainage system, and a sump pump inside the basement. The drainage system is installed around the perimeter of the basement floor and collects water that seeps through the foundation walls and the floor. The collected water is then directed to the sump pump, which pumps the water out of the basement and away from the foundation of the home.

Interior Waterproofing Cost - $70-$350/linear foot

Installation of Backwater Valve or a Backflow Preventer

A backwater valve is a plumbing device designed to prevent sewage or wastewater from flowing back into a building's plumbing system during instances of high water levels or flooding. This is a popular service that will help protect your basement from sewer back up and potential water damages associated with it.


If you are experiencing wet basement problems or see foundation leaks on your walls, this could be a sign that you need a foundation leak repair. The first step is often foundation leak detection. Our teams are trained to deliver quality foundation leak detection & repair services and have all the necessary equipment with them. Let us find the leak in your basement & do the foundation crack repair to address it!

Waterproofing Contractors installing a weeping tile in front of CN Tower

Weeping tile installation and weeping tile cleaning services are crucial parts of making sure your wet basement problems are solved. A weeping tile drainage system will help collect water around your foundation and will direct it away. This way the amount of water around your basement is reduced which can help reduce the damage it can do to the foundation walls and your basement.

Basement Underpinning Project in Progress near Nathan Phillips Square in Toronto

Process of strengthening and stabilizing a home's foundation by excavating soil beneath the existing foundation and extending the foundation's depth. This process is typically done to increase the height of the basement or crawlspace, reinforce a weak foundation, or repair damage caused by settling or shifting soil.

Basement Underpinning Cost - $85-$450 per linear foot

Basement Wall Crack Repair in Progress

Simple foundation cracks are often repaired by injection an epoxy solution into the crack. The epoxy material fills the crack and hardens, effectively sealing the crack and preventing further water intrusion. However, in some cases, more extensive foundation repairs may be needed - such as stitching.

Foundation Crack Repair Cost - $1,500-$3,200

A waterproofer sealing the crawlspace of a building

Crawlspace encapsulation involves a number of services that are designed to protect your crawlspace from water damage, improve air quality in your home, and more. During the process, crawlspace will be sealed, and foundation walls may be repaired. Some projects may also involve the installation of a sump pump, dehumidifier, crawlspace insulation and other services.

Example of Basement Walkout

A basement walkout construction project involves creating an accessible entrance from the basement level of a building directly to the outdoors. This typically involves excavating a portion of the foundation wall and installing doors and/or windows that provide a means of entry and exit. The result is a convenient transition between the interior of the basement and the exterior of the building, often leading to a yard, patio, or outdoor space. This can help make your basement more usable and in some cases may even allow you to turn a part of your property into a rental.

How Long Does Basement Waterproofing Take?

How Long Will my Project Take?

Basement waterproofing services can take anywhere from 1 day to 2+ weeks to complete. But of course, duration of your project will depend of factors such as ease of access, specific services, and more. For example, Internal Waterproofing typically takes up to 2 weeks, Exterior Waterproofing also takes about 2 weeks, Wall Crack Repair - 1 day, Bench Footing - about 5 weeks, and Basement Underpinning - also takes about 5 weeks. Window well installation normally takes 1-2 days, while Crawlspace Encapsulation will take 3-10 days.
