Root Cause

Most Companies Remove Mold. We Fix Why It's Growing.

Mold removal treats the symptom. Mold remediation treats the cause.

When mold grows in a Maine home, it's because moisture found a way in — and stayed. Freeze-thaw cycles, ice dams, poor ventilation, and insulation gaps all create the conditions mold needs to thrive. Remove the mold without fixing the moisture source, and it comes back.

Mattra identifies and corrects the moisture source as part of every remediation. That means attic insulation gaps, basement air leakage, crawl space vapor issues — whatever caused the mold to grow in the first place. We don't just remove it. We stop it.

Our Process

Our Mold Remediation Process

1

Assessment & Scope

We evaluate the full extent of the problem — visible growth, hidden moisture, and air quality — and document findings before any work begins. You'll know exactly what's there and what remediation requires.

2

Containment

We isolate the affected area with physical barriers and negative air pressure to prevent cross-contamination to unaffected parts of the home. HEPA filtration runs continuously throughout the project.

3

Safe Removal

Contaminated materials are removed according to IICRC S520 standards. This includes affected drywall, insulation, and structural materials as needed. We handle all demolition — no need for a separate contractor.

4

Antimicrobial Treatment

All affected surfaces receive EPA-registered antimicrobial treatment to eliminate remaining spores and inhibit regrowth. Treatment is applied to structural elements, subfloors, and framing — not just visible surfaces.

5

Clearance Verification

Post-remediation air quality testing confirms the space meets IICRC standards before we close up. You receive written clearance documentation — required by many lenders and insurers.

Every Part of Your Home

Mold Remediation in Every Part of Your Home

Attic Remediation Includes

Full mold removal from sheathing and framing
Ventilation assessment and correction
Insulation replacement if contaminated
Root-cause moisture correction

Attic Mold Removal

Attics are the most common site for mold in Maine homes. Inadequate ventilation and insulation failures allow moisture to accumulate all winter.

We remediate attic mold and correct the ventilation and insulation conditions that caused it — so it doesn't come back.

Basement Remediation Includes

Full mold removal from walls and floors
Moisture intrusion source identification
Drainage and vapor barrier assessment
Waterproofing recommendations

Basement Mold Removal

Basements trap moisture year-round through foundation seepage, condensation, and air infiltration.

We remediate basement mold and identify the moisture intrusion source — whether that's a drainage issue, vapor barrier failure, or air leakage.

Crawl Space Remediation Includes

Full mold removal from joists and subfloor
Vapor barrier installation
Encapsulation for long-term moisture control
Dehumidification assessment

Crawl Space Mold Removal

Crawl spaces are especially vulnerable due to soil moisture, poor air circulation, and seasonal humidity swings.

We remediate crawl space mold, install vapor barriers, and address long-term moisture control through encapsulation.

Wall & Ceiling Remediation Includes

Source identification (plumbing, roof, condensation)
Safe removal of affected materials
Antimicrobial treatment of framing
Rebuild from one team

Wall & Ceiling Mold Removal

Mold inside walls and ceilings is often caused by plumbing leaks, roof damage, or condensation on cold surfaces.

We locate the source, safely remove affected materials, and rebuild after remediation — from one team.

Basement Waterproofing

If moisture intrusion is the source of your basement mold, we address it with interior drainage, sump systems, and waterproofing solutions.

FAQ

Common Questions About Mold Remediation

Mold remediation cost varies based on the scope — the size of the affected area, the type of mold, and whether structural materials need to be removed. Contact us for a specific estimate. We give you a clear, itemized breakdown before any work begins.

Most residential remediations take 1–5 days depending on scope and complexity. Projects involving significant demolition and rebuild may take longer. We'll give you a realistic timeline after the initial assessment.

It depends on the location and scope. Containment barriers and negative air pressure protect unaffected areas during remediation. In cases involving extensive work or sensitive occupants — young children, elderly, or immunocompromised individuals — temporary relocation is advisable. We'll be straightforward with you about what your situation requires.

Mold removal is a surface treatment that eliminates visible growth. Mold remediation is a comprehensive process: containment, safe removal of contaminated materials, antimicrobial treatment, moisture source correction, and clearance verification. Remediation addresses why the mold was there, not just what was visible.

Coverage depends on the cause. Mold resulting from a sudden covered event — such as a burst pipe — may be covered. Mold from chronic moisture issues typically is not. We can provide written documentation of findings and scope to support your insurance claim when applicable.
