Signs of Excess Moisture In Your Basement or Crawl Space

A dry basement is a safe basement! Whether you have a finished basement or your crawl space is nothing more than a small opening under the stairs of your house, too much water can lead to serious structural damage. You should definitely consider waterproofing your basement if you notice any of these issues happening in your home:

Musty Odors

A musty or damp smell in your basement is often the first sign of trouble. This odor is caused by the presence of mold or mildew, which thrive in damp environments. Most homeowners assume that all basements smell this way, but if you notice a persistent musty smell, it’s essential to investigate further and identify the source of the moisture.

Mold or Mildew

If you see patches of mold or mildew on the walls, floors, or belongings in your basement, it’s a clear indication of water leaks. Mold growth can be harmful to your health and can also cause damage to your property over time. Installing a vapor barrier can prevent mold and keep your basement in good shape.

Damp or Wet Basement Wall(s) or Floors

Touch your basement floor and walls to check for dampness, wet spots, or standing water. Persistent moisture on basement or crawl space surfaces can be a sign of water seepage or leaks, which need to be addressed promptly to prevent further damage.

Water Stains

Over time, water pooling in the same places can lead to marks on concrete. Look for water stains on the concrete walls, floors, or ceiling of your basement. These stains may appear as discolorations or dark spots and can indicate past or ongoing water intrusion.

Peeling Paint or Wallpaper

Water leaking through concrete walls can cause paint or wallpaper to peel or bubble. If you notice this happening to your basement wall(s), it could be a result of water infiltration.


Efflorescence is a white, powdery substance that forms on concrete surfaces due to the migration of salts. It is a clear sign of water intrusion through the concrete, so don’t wait to give us a call if you notice that your basement wall(s) have this issue.

Wet or Damp Belongings

Check your belongings stored in the basement for any signs of being damp or wet. Excess moisture can damage furniture, cardboard boxes, documents, and other valuable items.

Exterior Basement Waterproofing FAQs

Treating the outside of the basement creates a barrier that prevents water from seeping into the foundation. Keeping water away from your foundation helps maintain the structural integrity of your home and prevents potential issues like foundation cracks, mold growth, and basement flooding. Investing in exterior basement waterproofing in Nashville, TN, can save you from costly repairs in the long run and provide you with a dry and stable living space.

While there are various DIY water protection products available, exterior basement waterproofing is a complex, labor-intensive, and time-consuming process that requires specialized knowledge and equipment. It involves excavating the soil around your home’s foundation, utilizing specific tools and materials, and installing an exterior drainage system to redirect water away from the foundation. A small mistake during the installation can compromise the effectiveness of the entire system. To ensure reliable and long-lasting protection, it’s best to leave exterior basement waterproofing to the professionals. At BWS, our experienced team has the expertise and skills to provide effective solutions tailored to your specific needs.

The best way to waterproof exterior basement walls typically involves the application of a moisture barrier or protective membrane. These waterproofing products create a second layer of protection that prevents water from penetrating the basement wall. However, our choice of materials and methods may vary depending on factors such as soil conditions, climate, and the severity of water intrusion. We will assess your property’s unique requirements and recommend the best solution for your exterior basement walls.

The cost of exterior basement waterproofing can vary based on factors such as the size of your home, the extent of waterproofing required, and the chosen waterproofing materials. While it may be an upfront investment, the procedure provides long-term protection and peace of mind. We offer competitive pricing and provide transparent cost estimates for all of our services. We believe in providing value for your investment by delivering high-quality workmanship and durable waterproofing solutions that stand the test of time.

Interior waterproofing is beneficial for managing water that has already infiltrated your basement. However, it does not prevent water from reaching the exterior walls of your foundation. Exterior basement waterproofing provides a comprehensive solution by creating a barrier that keeps water away from the foundation walls in the first place. Combining interior and exterior waterproofing can provide optimal protection for your basement and foundation, ensuring a dry and stable living environment. If you have existing interior waterproofing or are considering basement waterproofing, don’t overlook the importance of exterior protection. We will assess your property and determine what will work best for your space.
