Basement Waterproofing in Burlington County, NJ

The main approaches

• Fix the outside first. Clean gutters, extend downspouts well away from the house, and regrade soil so it slopes away from the foundation. This is the least invasive step and sometimes the only one needed.
• Interior drainage (drain tile). The contractor cuts a channel in the floor along the walls, lays a perforated pipe in stone, and routes the water to a sump pump that sends it outside. It does not stop water from reaching the wall, but it controls it before it spreads across the floor. This is one of the most common fixes for groundwater seeping in where the floor meets the wall.
• Exterior excavation and membrane. The soil is dug down to the footing, the wall is cleaned and coated or wrapped with a waterproofing membrane, and drainage is added at the footing. It addresses water at the source, but it is disruptive: decks, walkways, landscaping and utilities are in the way.
• Coatings and sealers. Masonry waterproofing paints can reduce dampness on some walls, but they are not designed to hold back water under pressure. Be cautious about being sold coatings alone for active leaks.

Signs to describe in your request

• Where the water shows up: a single crack, the floor-wall joint, one corner, or everywhere.
• When it happens: every rain, only after long storms or snowmelt, or only in spring.
• White, chalky deposits (efflorescence) on block or brick, peeling paint, rust on the bottom of appliances, or a musty smell.
• Whether the basement is finished, and whether there is an existing sump pit.

Questions to ask a waterproofing contractor

• What is your New Jersey Home Improvement Contractor registration number?
• Where do you think the water is coming from, and why does your system address that?
• What is the warranty, what exactly does it cover, and does it transfer if I sell the house?
• Where will the sump discharge, and does my town or sewer utility restrict that?
• Does the job need a permit or electrical work, and who arranges it?

Moisture is not always a leak

In humid New Jersey summers, cool basement walls can sweat, which looks like seepage. A simple test is to tape a square of plastic to the wall for a couple of days: moisture on the room side points to condensation and humidity, moisture behind it points to water coming through. A dehumidifier may be part of the answer either way.
