Frequently Asked Questions

Why should I be concerned about basement waterproofing?

A wet basement might seem like a small problem, but it can lead to much bigger ones. A leaking basement, or a basement that generates a lot of moisture, can attract black mold or cause structural damage to your home’s foundation. A leaky basement also runs the risk of soaking any belongings you store there, and destroying your basement finishes. Basement waterproofing can steady your home’s property value and provide peace of mind.

What are the signs of a basement leak?

Leaking basements present a few very obvious indicators, like pools of water on the floor or water trickling down the walls. But there are a number of other ways water damage can show itself as well:

  • An increase in mold or mildew
  • Musty odors & damp spots on the walls or floor
  • A white, chalky substance on the walls
  • Cracks in the walls or floor
  • Peeling paint or bubbling wallpaper
  • Rust on appliances or other metal objects
  • Wood rot
  • Warped paneling or trims

What can cause a leaking basement?

Water is able to seep into your basement through cracks in the walls or floor, but there are plenty of other places it can seep through. Look for weak spots around your basement, such as mortar joints (spaces between bricks or concrete blocks), tie rods that reinforce masonry, the juncture where the walls meet the floor, the top of your home’s foundation, or window wells. If there are congested and/or blocked weeping tiles or no weeping tile system installed around the perimeter of your home’s footing, the water simply has no where else to go but inside any of these entry points.

What may contribute to my basement waterproofing and/or mold problem?

Frequently, wet basements occur in homes that lie in low-level areas at the bottoms of slopes or hills, but the everyday shifting or settling of your home may also cause leakage. Other potential causes may be poorly-mixed foundation concrete or improperly designed drainage systems. Tree roots may also grow into the weeping tile system and block water flow. Finally, weather can be a factor.

What is the difference between exterior and interior foundation waterproofing?

Exterior foundation waterproofing preserves the structural integrity of your foundation, and does not allow any water or moisture to seep through the block, brick or concrete. Moisture presence in your foundation can lead to deterioration over time, and result in costly foundation repairs or complete foundation rebuilds. Waterproofing internally can be a lot less expensive, and works more as a diversion process for water. Water is still able to enter through the foundation, but is diverted underneath the floor area into an internal weeping tile system.

What kind of basement waterproofing can I do on my own?

The best way to keep water out of your basement is to keep it away from your home’s foundation, and there are several ways to do this. Keep the ground around your house sloped away from it, and free from shrubbery or plants that might prevent sunlight from drying out the soil. Install gutters and downspouts, keeping them regularly clean of debris, and make sure they drain well away from the foundation (either by piping it underground or extending the gutters away from your home). Keep your home’s window wells covered so they don’t collect water.

Why would my drainage system need a sump pump and battery backup?

Your drainage system only requires a sump pump if the weeping tile system installed has no other gravity fed drainage source. In some locales, sump pumps are also required by the Building Code. Sump pumps are installed in a gravity fed “pit”, once the water level rises to a certain height, the sump pump automatically turns on and discharges the water outside of the house to the exterior grade. Sump pumps are electrically powered, and sometimes need battery backups. A rainstorm that’s strong enough to cut your electrical power is definitely the kind of storm that will fill the pit and require it to be working during such time.

What is black mold?

Black mold, or Stachybotrys chartarum, is one of the leading causes of poor indoor air quality in homes. It is commonly found in damp or flooded homes, and requires constant moisture in order to grow. Foundation waterproofing will prevent any further moisture/water penetration into the basement and will stop any further mold growth.

What will it cost to solve my black mold or basement waterproofing problem?

Ultimately, the price will depend on the solution. Some variables that influence the cost of waterproofing foundations include: complexity of excavation, spacing between foundation and neighboring property, concrete, interlock, asphalt, flagstone removal and replacement, depth of foundation, soil conditions, shrubbery & trees.
