Crawlspace Waterproofing in Cherry Hill, New Jersey

Professional crawlspace waterproofing serving Cherry Hill and surrounding areas.

Crawlspace waterproofing in Cherry Hill fixes the damp spaces under the township’s raised sections, additions, and mid-century homes. Water Damage Pros US encapsulates, seals, and dehumidifies crawlspaces across Camden County — because vented spaces stay wet in this coastal-plain climate.

Why Cherry Hill Crawlspaces Stay Wet

The vented-crawlspace design that predates modern building science fails in South Jersey’s humid climate: summer air rolls in through foundation vents, hits the cool space, and condenses on joists, ducts, and insulation. Ground moisture adds more from below, especially on the coastal plain where the water table runs high. The result is crawlspace humidity above 70 percent most of the year — enough to grow mold on framing and push that unmistakable musty smell up through the floors above.

Our Crawlspace Waterproofing Process

  1. Assessment — Moisture levels, drainage, and existing damage are measured and documented.
  2. Drainage fixes — Standing water is managed with grading, drains, or a crawlspace sump where needed.
  3. Encapsulation — Heavy-duty liner seals the floor and walls, with seams sealed airtight.
  4. Air sealing — Vents, rim joists, and penetrations are closed to outside air.
  5. Dehumidification — A crawlspace-rated unit holds humidity below 60 percent year-round.

Frequently Asked Questions

Should crawlspace vents be open in summer here?

In this climate, no — sealed and conditioned outperforms vented in every humid region. The air coming in is the problem, not the cure.

Does encapsulation stop floor cupping above?

Damp crawl air is a common cause of hardwood cupping, and encapsulation usually stabilizes floors that were moving with the seasons.

FAQ

Frequently Asked Questions

Why are Cherry Hill crawlspaces always damp?

Vented crawlspaces pull in humid South Jersey air, and the coastal plain's high water table wicks moisture through the ground. The space stays near saturation for months.

Does encapsulation help with the musty smell upstairs?

Yes — crawl air moves up through the floor, so sealing the space and conditioning it removes the source of the odor.

What does crawlspace encapsulation cost?

Vapor barrier alone runs $1,500–$4,000; full encapsulation with dehumidifier $4,000–$10,000.
