Basement Waterproofing questions, answered by experts

Periodic inspections and addressing drainage issues prevent further damage.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.

Water that pools under pavers can erode the soil foundation and weaken the paver structure. In some situations, it can also cause mold and mildew growth. If that happens, you may need to start budgeting for the cost to build and install a patio to replace the damaged one.
