Mold Remediation in New Jersey

Mold in a basement or crawl space almost always comes from moisture: a leak, high humidity, or water coming through the foundation. We remove the mold, treat the area, and fix the water problem behind it so it doesn’t come back.

Effective Basement Solutions has worked in New Jersey basements since 2011 — with our own crews, never subcontractors. Every job comes with a written Mold Remediation Certificate and a 12-month limited warranty on the treated areas. Call or text 1-800-957-0075 for a free estimate.

Signs You Have a Mold Problem

  • A musty, earthy smell in the basement or crawl space
  • Black, green, or white spots on drywall, wood framing, or stored items
  • Stained or soft drywall along the bottom of basement walls
  • High humidity, condensation on pipes or windows
  • Mold showing up after a leak, flood, or sump pump failure

Not sure? We’ll look at it for free and tell you honestly what it needs.

Done Right the First Time

Remove what can’t be saved

Moldy drywall, carpet, and insulation are cut out and taken away. Surface cleaning can’t reach mold growing inside soaked materials, so we remove them.

Treat the framing and concrete

Exposed wood framing, studs, and concrete are cleaned and treated, including whole-house framing before new drywall and insulation go in.

Fix the moisture source

Mold comes back if water keeps getting in. We can fix the cause with an interior French drain, a sump pump, dehumidification, or crawl space encapsulation.

Why Mold Keeps Coming Back

Mold needs moisture to grow. If the area is treated but water still comes through the walls or floor, or the space stays humid, mold returns. That’s why we treat the mold and the water problem together.

Basement Mold vs. Crawl Space Mold

Both start with moisture, but they’re handled differently. We’ll tell you honestly what your space needs.

Basement Mold

Usually on drywall, framing, and carpet near the floor after water comes in. We remove damaged materials, treat the area, and fix the leak.

Crawl Space Mold

Usually on floor joists and insulation from damp air and bare dirt. Treatment plus encapsulation keeps it dry.

Mold Remediation FAQ

Can I just clean mold with bleach?

Surface cleaning may lighten stains, but it doesn’t remove mold growing inside soaked drywall, carpet, or insulation. Those materials usually need to be removed.

Will the mold come back?

Not if the moisture is fixed. That’s why we look for the water source on every job. The treated areas carry a 12-month limited warranty.

Do you also fix the water problem?

Yes. We install interior French drains, sump pumps, dehumidification, and crawl space encapsulation — the same crew can handle both.

Do I get a certificate after the work?

Yes. You receive a written Mold Remediation Certificate with our NJ license and a 12-month limited warranty on the treated areas.

Do you replace the drywall afterward?

No. We remove the damaged materials and treat the area; putting back drywall, insulation, and finishes is up to the homeowner.
