Common Basement Leak Repairs 

Signs that you Need Basement Waterproofing Services in Newmarket

Signs that you Need Basement Waterproofing Services in Newmarket?


Many people leave basement waterproofing for later, until major water damage happens. The best approach is to prevent water damage before you need leaky, or wet basement repairs.


First warning signs of potential water intrusion often include:

  • Foundation cracks – on basement walls of floors

  • Dampness – wet spots on basement walls or floors

  • Leaks – following heavy rains or snow melts

  • Air quality – the musty smell is a common concern among Newmarket residents

  • Mold – along with mildew may be obvious or hiding under the floor or wall coverings


Thanks to hydrostatic pressure, water will find the path of the least resistance making it through the cracks or entering your basement through other areas like tie rods or where the wall meets the floor.


Aquamaster Waterproofing has all the tools and expertise required to prevent and repair basement leaks and wet basement problems. Book a FREE estimate today!


Cost of Waterproofing in Newmarket

The average cost of exterior basement waterproofing in Newmarket ranges from $95-$100 depending on the details of the project. When estimating the cost our team will look at the size of the area, foundation damage, ease of access to the wall, and waterproofing services included in the project. We normally see a total cost of basement waterproofing range from $2,000 to $50,000+ depending on what exactly is involved in the project. There are many alternatives and options for both interior and exterior waterproofing. Exterior waterproofing up-front cost is higher. But it will save you money in the long run as it’s considered a long-lasting, low-maintenance solution.

Waterproofing Project Durations

Wet basement repairs and basement waterproofing projects can take from 1 day to over 2 weeks to complete.  Duration of each project depends on the specific scope of work. For example, Interior Basement Waterproofing and Exterior Basement Waterproofing projects take from 1 day to 2 weeks to complete. One day is normally needed to repair basement cracks, but more extensive Foundation Repairs take longer to complete. Crawlspace Encapsulation takes 3 to 10 days, and Basement Walkout construction and Bench Footing typically take 4-5 weeks.

Exterior basement waterproofing will help protect your basement walls from contact with water. This method normally includes a number of services - applying waterproofing membranes, weeping tile installation, and more. Basement walls will be repaired and shielded from contact with water, while the drainage system will divert water away from the foundation.

Basement Underpinning Project in Progress near Nathan Phillips Square in Toronto

Basement underpinning is one of the floor lowering services that will strengthen the foundation of your property and will lower the basement floor.

Waterproofing Contractor Installing a Window Well

Window well installation Newmarket often includes installing a drainage system. Together the window well and the weeping tile will protect your windows from water intrusion, in some cases, window wells can also include an egress.  

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

Plumbing Rough Ins Installed in the Basement

Our team of contractors will install pipes and vents for the plumbing system for your new construction project. This service involves routing pipes through wall cavities, running vent stacks to the roof, laying underground pipes, and installing fixtures and end elements etc.

Example of Interior Basement Waterproofing Project

In most cases, interior waterproofing includes the installation of waterproofing membranes, weeping tiles, and a sump pump to collect the water that makes it through the basement walls and push it outside the basement. While this service is often more affordable compared to exterior waterproofing, it requires ongoing maintenance and doesn't prevent water from making it inside your basement.

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

Basement Wall Crack Repair in Progress

Foundation repair Newmarket involves repairing wall and floor cracks, as well as damage done by water intrusion through the cracks. We use a variety of methodologies from epoxy injection into the crack to foundation piering, wall stiching and more. 

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


Basement leak detection service will identify the source of the basement leak. This service is especially popular when you basement is finished and it is unclear where the water is coming from. Once the source of leak is identified our contractors will repair the wet basement.

Waterproofing Contractors installing a weeping tile in front of CN Tower

Weeping tile system is often used in landscaping, interior and exterior basement waterproofing and for other applications. Our service can also include hydro jetting (weeping tile cleanout), but in some cases you will need to replace the drainage system.

Sump Pump Installation and Battery Backup Replacement Example

Sump pumps are a common element of interior waterproofing systems. They help remove an excess of water that makes it through your basement. Once installed, the sump pump will require regular maintenance to make sure that it remains in good working condition to prevent possible floods.

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

Installation of Backwater Valve or a Backflow Preventer

Backwater valves, and backflow prevention devices are critical to keeping your property safe, in sanitary condition. These devices prevent dangerous sewage water from backing up into your home. Some municipalities in Ontario offer rebate programs on backflow preventer installation.

Cost of Backflow Preventer Installation - $1,500-$4,000+

A waterproofer sealing the crawlspace of a building

Some homes have crawlspaces instead of basements. Crawlspace encapsulation will insulate and seal your basement from moisture. These services can also include dehumidifier installation, crawlspace insulation, sump pump installation and more, depending on the problems you are seeing with your crawlspace.

Example of Basement Walkout

Basement walkout construction will make your basement into a functional space with a separate entrance, additional windows, and plenty of air flow. This is often used as a part of a basement conversion project to turn your basement into a gym, functional living space or even a rental unit.
