Mold Inspection & Remediation

Residential & Commercial

Professional mold inspection and remediation for homes and businesses in Brewer, Bangor, Bar Harbor, Mount Desert Island, and Central Maine. Penobscot Cleaning Services identifies hidden moisture, contains affected areas, removes mold-damaged materials, and remediates conditions that allow mold to return—protecting indoor air quality, structural materials, and occupant health.

Find it. Remove it. Stop it.

Fast detection and complete remediation.

With over 150 years of combined technician experience and four decades serving Penobscot and Hancock Counties, Penobscot Cleaning Services, Inc. delivers thorough mold inspection and remediation for residential, multi-family, and commercial properties. Fast action limits spread, reduces health risk, and prevents costly structural damage. Mold grows wherever moisture is present, and Maine’s changing weather, coastal humidity, freeze–thaw cycles, and common building designs create ideal conditions for growth. Mold can spread quickly behind walls, under floors, and in attics or crawlspaces—often before it’s visible. If you notice visible mold, musty odors, or have experienced water damage, leaks, or flooding, immediate inspection is critical. Early remediation reduces repair costs and helps prevent recurring mold problems..

When to Call for Mold Remediation

Call immediately if you see mold growth, smell persistent musty odors, experience unexplained respiratory irritation, or after any water event such as burst pipes, roof leaks, basement flooding, or appliance failures. Mold often develops within 24–48 hours of moisture intrusion and may be hidden from view.

Thorough Mold Inspection & Remediation Process

Step by Step:

Visual inspection & moisture mapping
We look for staining, condensation, and water intrusion and map moisture patterns to define the scope of work.

Thermal imaging & borescope inspection
Infrared cameras and borescopes locate hidden moisture and mold behind walls, ceilings, and structural cavities.

Air & surface testing (as needed)
Optional testing helps guide remediation and document conditions for complex cases or insurance purposes.

Containment & negative air control
Affected areas are sealed off and placed under negative pressure to prevent cross-contamination.

HEPA air filtration
Air scrubbers capture airborne mold spores during remediation to protect occupants and unaffected areas.

Removal of mold-affected materials
Unsavable drywall, insulation, carpeting, and other contaminated materials are removed and disposed of safely.

Cleaning, disinfecting & odor control
Remaining surfaces are cleaned and treated with antimicrobial solutions where appropriate.

Drying & repair coordination
Air movers and dehumidifiers dry the structure thoroughly, and repairs are coordinated to restore the property.

Prevention & Recommendations
We provide guidance on moisture control, ventilation improvements, and long-term prevention strategies to help keep mold from returning.
