Basement Waterproofing

The Best Basement Waterproofing Company in New Castle County Since 1987

No matter how dry the soil is around your home, or how well-compacted the fill around your foundation, basements in the Wilmington, Newark, and greater New Castle County region are never completely free of moisture of some kind.

According to one consumer resource,

“Most serious basement moisture problems occur when water leaks or seeps through basement floors, through joints between floors and walls, or through walls below ground level during or after rainstorms. In extreme cases, this water may enter in visible rivulets and accumulate several inches deep. In the mildest cases, it slowly seeps through porous wall or floor materials, creating slightly damp walls or floors.”

There are other reasons for basement water leaks and flooding, as well.

As one plumbing company points out on their website,

“While usually associated with heavy rainstorms, basement flooding can happen at any time as a result of a plumbing failure. If a pipe, washer hose, water heater, or other pressurized water source leaks or fails, it can send hundreds of gallons of water per hour straight into your basement.”

And it’s not just water damage or moderate flooding that can be a concern for homeowners. The growth of mold and mildew can be another result of basement moisture.

So, why is mold a problem?

Mold can irritate individuals with seasonal allergies and other respiratory conditions, and act as a potential trigger for asthma attacks. The problem for homeowners with basements is that a damp or wet basement is also a perfect environment for mold and mildew spores to grow.

According to the Delaware Health and Social Services (DHSS),

“Mold is found where there is a moisture problem. High humidity, plumbing leaks and roof leaks can all contribute to mold problems. Dryers not properly vented and moisture in basements and crawlspaces that is not dealt with will also become larger problems.

Mold typically flourishes in moist, dark areas. It can grow in bathrooms, basements, attics and even inside the catch trays of refrigerators and air conditioners.”

Fortunately, with professionally installed basement waterproofing, Wilmington, Newark, and other New Castle County homeowner can sleep peacefully at night.

There are several good reasons for considering an expertly designed and professionally installed basement waterproofing solution from BWN. It will:

  • Reduce your energy bills
  • Avoid mold and mildew growth
  • Increase the resale value of your home

Foundation Repair

Get the Best Foundation Repair Service in New Castle County

Houses, like people, age over time. And, like people, things begin to sag, creak, and even start to break down a bit. Unfortunately, one of those aging issues are cracks that can develop in the foundations as well as gaps between the joints of walls and floors.

And, while you might be able to replace a roof or flooring, you really can’t replace a foundation.

The goal, then, is to repair foundation cracks and issues as soon as you spot them. However, foundation crack repair isn’t one of the categories in the average DIY homeowner’s skill set. Nor should it be.

According to home advice guru Bob Vila,

“Within a year after construction, hairline cracks (about the width of a sewing thread) commonly appear on the inside of basement walls, most often near windows and doors or in the corners of the basement. This is due to normal “settling,” or the concrete shrinking slightly as it cures..”

For foundation crack repair, New Castle residents have relied on Basement Waterproofing Nationwide for decades. So, when it comes to foundation repair, Newark, Wilmington, New Castle, Delaware City, and other communities throughout New Castle County make the call to BWN.

But you may not notice when it has finally worn out. Here are some signs that your sump pump is about to pump its last:

  • Running non-stop without shutting off
  • Running hot (to the touch)
  • Frequent cycling on-and-off
  • Not consistently starting up when it should
  • Making unusual noises
  • Excessive vibrating
  • Visible rusting
