Mold Removal From the Bones of Your Home
Structural mold grows on the materials that hold a house together: wall studs, top plates, roof and wall sheathing, floor joists and subflooring. It usually starts after a slow plumbing leak, a missed roof flashing problem or a flood that soaked the bottom of the walls and never dried. Because it lives behind drywall and under flooring, it can spread for months before anyone notices a stain or a musty smell.
Our New Jersey crews open the affected area under negative-pressure containment, remove what cannot be saved, physically clean the framing and seal it so the structure is sound and the air in your home is back to normal. We follow the IICRC S520 standard and EPA guidance on every job, from a single bathroom wall in Freehold to a full gut in Toms River.

We Remove Mold, We Don't Just Spray It
Fogging and bleach only bleach the color out of mold. Real structural remediation means removing contaminated drywall and insulation, sanding or blasting framing back to clean wood, HEPA vacuuming every surface and then sealing it. That is the only approach that passes post-remediation testing.
What Our Structural Mold Remediation Includes
Negative-Pressure Containment
Poly walls, zipper doors and HEPA air scrubbers keep spores inside the work zone and out of the rest of the house.
Controlled Demolition
Moldy drywall, insulation, baseboards and carpet pad are cut out, bagged in 6-mil poly and removed through the containment.
Framing & Sheathing Cleaning
Studs, joists and sheathing are wire-brushed, sanded and HEPA vacuumed until the wood is visibly clean.
Antimicrobial & Encapsulation
After cleaning we apply an EPA-registered antimicrobial and a mold-resistant encapsulant to treated wood.
Moisture Correction
We confirm the leak is fixed and the framing is below 15% moisture content before anything is closed back up.
Clearance Testing
An independent air and surface test confirms the area is clean before containment comes down.
Signs You May Have Structural Mold
Structural mold is rarely visible on day one. Homeowners usually call us after noticing one or more of these warning signs:
- A musty odor that gets stronger in one room or when the heat or AC turns on
- Baseboards, drywall or trim that feel soft, bubbled or stained at the bottom
- Peeling paint or dark spotting on a wall that shares a bathroom, kitchen or laundry room
- Cupped or squeaky flooring above a damp basement or crawl space
- A past leak, ice dam or flood that was dried with fans only
How Our Structural Mold Remediation Works
Every project starts with a visual inspection, moisture mapping and, when it is useful, air or surface sampling. From there we write a scope that lists exactly which materials come out and which can be cleaned. We set up containment and HEPA air filtration, remove the damaged materials, clean the framing, treat and encapsulate it, and run air scrubbers until the space is clean.
Before we take containment down, an independent assessor can perform clearance testing so you have written proof that the work succeeded. That paperwork matters if you plan to sell the house or need to close out an insurance claim.
What Drives the Cost
Pricing depends on the square footage of affected material, how much needs to be removed versus cleaned, access (a finished basement ceiling is very different from an open attic) and whether rebuild is part of the job. Most single-room wall projects in Monmouth and Ocean County take two to four days. You get a written, line-item estimate after the free inspection, before any work begins.
