Q: Why is basement waterproofing important?

A: While it may seem like a mere inconvenience, a wet basement can actually cause a host of problems. The dampness may cause mold and bacteria which present health issues; water in the basement risks ruining anything you have stored there; and dampness can cause structural rot. Having professionals waterproof your basement can provide a healthier home, an aesthetically more pleasing living environment, and can increase your home’s property value.


Q: What are the signs of a wet or damp basement?

A: The obvious signs, of course, are water running down walls or pooling on the floor. However, other indications can include:

  • Cracks in the foundation along the walls or floor
  • A musty smell
  • Rust on items in the basement
  • Rotting baseboards or other structural items
  • Paneling that is warped, peeling wallpaper, or bubbling paint
  • Mold – black, brown, yellow or green
  • Efflorescence – A white or gray substance on walls caused by salt left from evaporating water
  • Water stains on the walls or ceiling


Q: Is a wet basement unusual, and does it indicate a poorly built home?

A: It’s not unusual at all to have a wet basement. In fact, most homes will experience a wet or damp basement at some time, according to the National Association of Realtors.


Q: Do occasional leakages, or very slight dampness, require correction?

A: Not always. There are many reasons why your home may experience occasional leakage. If you have taken obvious corrective steps and yet still have water in your basement, then it’s time to call us to assess the situation. Because basement water problems can affect your home’s value, as well as the health of those living in it, you want to act sooner rather than later.


Q: What are the causes of a wet or damp basement?

A: There are a number of reasons why a home may have a wet basement, some of which include:

  • Cracks in the foundation can allow the water to seep in
  • The grading along the perimeter of your house may not be adequate to drain away water
  • Leaking plumbing
  • Weak mortar joints and cove joints
  • Improperly sealed or seated window wells

Our expert technicians are trained to locate the source of water issues, and devise a permanent solution, thus eliminating future water problems.


Q: Why do I need an emergency Battery Back-Up System?

A: When we install sump pumps as part of your water solution, they are electrically powered. If a storm causes your home to lose electricity, that’s the very time you need your pump fully functioning. The battery back-up will provide your system with the ability to operate properly during times of electrical outages.
