HOW MUCH DOES IT COST TO FIX A BASEMENT LEAK?

HOW MUCH DOES IT COST TO FIX A BASEMENT LEAK?


The cost to fix a leaky basement comes down to the severity of the situation. It also depends on the condition and size of the home in question.
It’s important to have a ballpark idea of cost, since we are in the teeth of winter now. Soon the ground is going to thaw. The average annual precipitation has increased in Canada, with continued change in the earth’s climate. Heavier and more frequent rainfall is a big factor as spring approaches.

All that excess moisture is going to put more pressure on the foundation of the home, pushing up against timber, block structures, floors, and bricks, and that in turn can lead to basement leaks. A common area to find a basement leak is where the floor and walls meet.

The purchase of a home is the most significant investment most of us will make in our lifetime. Cost estimates to fix water damage vary, but it’s in the thousands, all to replace floors, hardwood, drywall, and anything electrical. Mould is a whole other issue, with both monetary and health impacts.

How much should a homeowner budget, in the event of a basement leak, even a flood, and you have to call a waterproofing company?

The homeowner can buy an epoxy or polyurethane foam injection, as well as a putty knife, wire brush and caulking gun, for a crack in a concrete foundation, for around $30 at Home Depot. You can buy waterproofing paints for $50-$60, or hydraulic cements, around $15-$20 for a ten pound pail. But these are not comprehensive solutions. Water will continue to build up behind the walls, looking for new ways to seep into the basement. That’s particularly true in older homes.

Basement waterproofing along the exterior of the home is more expensive, but people opt for this because it tackles the problem of water leakage at its source.
It’s a comprehensive, multi-step process involving major excavation work, cleaning walls and repairing cracks, installing protective coating and a drainage membrane, as well as a new weeping tile, and it’s the best way to keep your basement dry. You will need to call on licensed, professional waterproofing contractors to do the job, since it’s complicated and labour-intensive. It’s not something to be left in the hands of amateurs, armed with not much more than a YouTube video.

Costs for exterior waterproofing starts at around $100 per foot and can go up to $1,000 per foot, again depending on the size and difficulty of the job. The depth of the home’s foundation is a major issue in determining cost.

Interior waterproofing isn’t as expensive as waterproofing around the exterior of the home. This option is for homeowners running a tighter budget, or perhaps their home is located too close to neighbouring properties, making major excavation work impossible. Interior waterproofing can also be looked at as another layer of home protection for those who also opted for the exterior route.

Interior water management systems control water that has already entered through the foundation walls or from under the home’s footing away from the finished interior of the basement. It involves setting up a drainage system in the home – including the installation of a protective drainage membrane along the walls up to grade level, connecting a new weeping tile to the home’s drainage system, and installing a sump pump (which directs water to an outside location, away from the property).
The cost for interior waterproofing is anywhere from $75 per foot up to around $250 per foot.

The city of Toronto offers subsidies to homeowners for the installation of flood protection devices, to help offset waterproofing costs.
Call a waterproofing company in Toronto to come out and assess your situation, and to get a quote. If you are fortunate enough to still have a dry basement, with no leaking, it’s best to get ahead of any potential issues that might arise as we get into spring.

Investing now in a waterproofing system can save you a ton of money in repair costs and emotional turmoil down the line, in the event of a basement leak.
