6 Signs You Need to Call Our Waterproofing Specialists

A damp or musty smell

Even if there’s no visible indication of water seepage, musty odors are good clues that there’s a problem with your foundation.


We all know how dangerous mold can be. If mold is present in your basement, you need to discover the source of the entering water quickly.


This is another visual indication of water seepage. Efflorescence is a chalky white substance that indicates cracks or other foundation openings are nearby.

Cracks in your floor or walls

Any crack in your foundation wall has the potential to become a problem and will only worsen with time. These should be addressed as soon as possible.

Bowing walls

If you notice curves or bulges in your concrete foundation, call for immediate service. Without help, the pressure will certainly cause cracks to form.

Water marks

Water stains equal water seepage, plain and simple. The root cause could be poor grading in your yard and sending water over the top of your foundation.
