Mold Remediation

Cost depends on the size of the affected area, the type of materials contaminated, and whether the mold is in an accessible location or hidden behind walls. A small bathroom mold problem is a different scope than a full basement with mold behind drywall on three walls. Every job starts with a free inspection and written estimate.

Most residential mold jobs take 3 to 7 days for containment, removal, and treatment. Add 2 to 5 days for post-remediation clearance testing and another 1 to 2 weeks if reconstruction is needed. Your project manager provides a timeline during the initial assessment.

It depends on the cause. If mold resulted from a covered water damage event (burst pipe, appliance failure), your policy typically covers the remediation. If mold is due to long-term maintenance neglect (chronic humidity, ongoing leak you knew about), it may not be covered. We document the cause and work with your adjuster to maximize your covered scope.

Mold produces allergens and, in some species, mycotoxins that can trigger respiratory symptoms, allergic reactions, and irritation of the eyes, skin, and throat. People with asthma, allergies, or compromised immune systems are at higher risk. The EPA recommends professional remediation for any mold-affected area larger than 10 square feet.

For very small surface areas (under 10 square feet on a non-porous surface), the EPA says homeowner cleanup with proper PPE may be sufficient. For anything larger, behind walls, on porous materials, or if you have health concerns, professional remediation with containment and clearance testing is the recommended approach.

We fix the moisture source. Mold cannot grow without water. Whether the issue is a plumbing leak, poor drainage, insufficient ventilation, or a cracked foundation, we identify and repair it as part of the remediation scope. We also recommend dehumidifier settings and ventilation improvements specific to your home.

Yes. Our technicians hold IICRC Applied Microbial Remediation (AMR) certification and follow the IICRC S520 standard. Redefined Restoration holds Illinois License #70156933 and carries general liability and workers' compensation on every job.

After we complete the removal and treatment, a third-party lab collects air and surface samples from the remediated area and compares them against outdoor baseline readings. If spore counts are within normal range, the area passes clearance and we can seal walls and begin reconstruction. If counts are elevated, we re-treat before proceeding.

Mildew is a surface-level growth that typically appears as a flat, powdery white or gray patch on shower tiles or window sills. It wipes off easily. Mold penetrates porous materials, appears fuzzy or raised, and comes in black, green, white, or orange colors. If the growth returns after cleaning or is on drywall, wood, or carpet, it is likely mold and should be professionally assessed.

Yes. Mold commonly grows on the backside of drywall, on wall studs, under flooring, and inside HVAC ducts. A musty smell with no visible source is a strong indicator of hidden mold. Moisture meters and thermal imaging can detect elevated moisture in wall cavities, and air sampling can confirm elevated spore counts even when no mold is visible.
