It’s a scenario that causes stressed-out homeowners: a leaky basement. This should be avoided at all costs because it can lead to extensive damage and create the perfect environment for a mould problem. Mould can be tricky to eliminate, it causes an unpleasant odour and it can even make you sick. To prevent this, you’ll need to ensure foundation cracks are repaired promptly. There are many causes of foundation cracks, though trees are usually blamed as the culprit. It’s usually more a case of poor drainage in the area around the foundation, not a direct result of growing tree roots. A good foundation contractor can usually isolate the cause, and this is as important to address as the problem itself.
