Crawl Space & Basement Moisture Control in Burlington County, NJ

Signs of a moisture problem

• A musty smell in the basement or rising into the house from a crawl space.
• Condensation on cold water pipes, ductwork or walls in summer.
• Mold spots on stored boxes, wood or drywall.
• Sagging insulation, rusty nails or damp floor framing in a crawl space.
• Cupping hardwood floors over a crawl space.

Common solutions

• Vapor barrier. Heavy plastic laid over the exposed soil of a crawl space to cut down on ground moisture.
• Encapsulation. A thicker liner that covers the floor and walls, sealed at the seams, often combined with sealing vents and adding a dehumidifier or conditioned air. Whether to close crawl space vents depends on the house, so ask the contractor to explain their approach.
• Dehumidification. A properly sized dehumidifier that drains to a sump or condensate pump, not a bucket that fills and shuts off.
• Drainage. If water actually stands in the crawl space after rain, drainage and sometimes a sump come first.

Mold and indoor air

We do not test for mold or offer health advice. If you are worried about mold or have health concerns, consider an independent indoor air or mold assessment, and be cautious of anyone who uses fear about mold to push an expensive job on the spot.

Radon

The New Jersey Department of Environmental Protection recommends that homes be tested for radon, and it certifies radon testers and mitigators in the state. Sealing a sump pit and cracks can be part of radon mitigation, but only a certified radon mitigation business should design and install a mitigation system. If you are already doing basement work, it can be a good time to test.

Cost factors

We do not publish prices. Crawl space size and height, access, existing debris or old insulation to remove, liner thickness, and whether a dehumidifier or drainage is needed are the main drivers.
