So you just bought a home or maybe you have been living there for many years.  The home can be 10 years old or 50 years old, one thing you don’t want is a wet basement.

Most homes that have basement leaks are in most cases due to cracked walls and or foundations.  The best way to repair a basement leak is from the outside.  We at Bearcat tell you straight up that outside excavation and waterproofing is the best way to repair period!

Just ask Mike Holmes or Brian Baeumler, as they also agree a basement leak must be fixed from the exterior for best results.

Your home is the largest financial investment you will make, a place where families come together and memories are made.

In Canada we have harsh weather conditions where your home needs protection that we all take for granted.  Like the things you don’t see that work 24/7 365 days a year such as:  your roof keeps out rain and snow, your attic insulation keeps your home warm in the winter and cool in the summer.  Your eaves trough gutter filter keeps your troughs clean so all the rain water can be diverted away from your basement foundation.  Your basement walls and foundation support the entire house.

Are you truly protecting your investment?

If your basement is damp or has a musty smell or even obvious small leaks developing then don’t waste your money on finishing your basement.  Unfortunately this problem must be addressed immediately in a preventative maintenance manner.  Although interior waterproofing has become a more common way to repair basements over the past 10 to 15 years and has cost saving benefits over exterior repair, the best option is still exterior waterproof repair.

A finished basement on average will cost $50,000 - $65,000, so you should definitely consider waterproofing prior to basement finishing.  If you decide to finish your basement and say no to waterproofing, if water damage occurs this can escalate water damage costs from $25,000-$30,000.  You may want to take a serious look at your home insurance policy as this may or may not be covered!

If you do have a basement leak, the following will need to be replaced.  You'll need new drywall, wood studs, tile floor, carpeting, sub floor, baseboards and trim, plaster and of course, repaint everything.

Another important point is don’t ignore the problem!  Many times the homeowner will see water leakage in the basement and ignore the situation with hope it is just a one-time occurrence.   Beware!!

This is not the case and will only worsen over time.  You also run the risk of mold and mildew spreading throughout the house creating serious health issues for you and your family.

Basement leaks can decrease your home’s value by at least 10%.  If your home is worth $500,000 – that’s a $50,000 loss you’ll take because of basement leaks.

Once you have made the right decision to have exterior waterproofing performed then make sure your reputable contractor chooses high quality products and solutions.  You do not want a pay now or pay a lot more later situation.

Let’s discuss the 4 main factors that can cause leaky basements.


Condensation is the most common culprit in which warm air interacts with cool foundation walls or even non insulated cold water pipes.  Damp proof the basement walls with a quality waterproof coating.  As for your copper piping, cold water pipes should be insulated.  Another preventative measure is to buy a quality style dehumidifier, they can work wonders.


Runoff develops when melted snow and/or rainwater is not properly diverted away from the home.  Water will take the path of least resistance and seep through cracks in your foundation walls or the footings.  Water should always be drained away from the foundation to avoid basement leaks.  An example of this is to install extended drain spouts to divert water away from the house and channel it to the sewer system.


Seepage occurs when the home is located beside a high volume water table.  These effects are the same as runoffs, the only difference is they will occur all the time and is also the most expensive problem to deal with. Chances are you will most likely need to have a sump pump installed and even internal drains around the foundation footings.

Clogged Eaves troughs

One more important factor that most homeowners neglect is their eaves troughs and clogged down spouts.  With the eaves troughs not functioning or draining properly this can create water saturation and overflow which can lead to water seeping through the walls and foundation.
