What Mold Removal Includes
During mold removal, the moisture source is located and the affected area contained; uncleanable materials are removed and salvageable materials dried.
Related types of work include mold cleanup, mold mitigation, mold remediation and mold abatement. Your scope should tackle the underlying water intrusion or humidity issue as well as damp materials and visible mold growth.
Wet materials should be dried within 24 to 48 hours to help prevent mold growth, the EPA advises. In Somersworth, a practical response is to stop the leak or humidity problem, limit disturbance, and check how far the growth extends before cleanup begins.
If your concern crosses a shared wall, ask who can authorize access on both sides and document which rooms need assessment.
- A musty odor or growth you can see
- Hidden moisture concealed by walls or floors
- Mold near HVAC equipment
- Flood or leak damage

Steps Before You Call Mold Removal Professionals in Strafford County
Avoid disturbing growth, save useful documentation and, if you can do so safely, stop the water.
Call (844) 352-3560- Stop the water safely. Shut off a leaking fixture or arrange a repair. Keep clear of wet electrical equipment and standing water.
- Limit access. Keep the door shut if possible. Keep children and pets away from visible growth.
- Avoid spreading particles. Never scrape or brush mold, or sand mold, without containment. Turn off HVAC equipment that may contain mold.
- Photograph the damage. Make a record of visible growth, damaged belongings and the leak before anything is moved. Ask the insurer which records it needs.
The Mold Remediation Sequence
Follow mold remediation steps in sequence: assess, set up containment, remove damaged material, clean and dry, verify results, and finally dismantle containment.
Mold Inspection and Moisture Mapping
A moisture meter and, when useful, a thermal imaging camera help trace the moisture source and affected materials.
Containment and Air Filtration
Build your containment barrier using poly sheeting. Clean rooms receive fewer migrating particles with negative air pressure and an air filtration device, the HEPA air scrubber.
Removal of Damaged Materials
Workers make use of protective equipment. Drywall removal or other demolition of damaged porous materials may be needed.
Surface Cleaning and Drying
A HEPA vacuum and damp wiping clean remaining non-porous surfaces. Use moisture readings, a dehumidifier and air movers to guide drying.
Final Cleaning and Verification
Post-remediation verification can involve clearance testing, a visual examination or air sampling, carried out by an independent assessor.

Mold Cleanup: Questions and Answers
How long does mold remediation take?
How long it takes depends on the affected area, material removal, drying and correction of the moisture source. Find out the work sequence before the start.
How can you look for mold in your house?
Search for a musty odor, visible growth and evidence of moisture by HVAC equipment, windows, plumbing and roofs. A mold inspection helps you trace damp materials. When growth and the water source are evident, mold testing may be unnecessary.
When does your situation call for professional mold removal?
For areas above about 10 square feet, extensive water damage, sewage or contaminated water, or an affected HVAC system, EPA guidance points you toward professional help.
Does the process change for black mold?
Color alone tells you nothing about how risky mold is. Use the affected area and moisture source, plus material and containment needs, to shape your removal plan.
Can mold return after removal?
Yes. Unresolved condensation, humidity or a leak can allow mold to return. Your remediation plan should explain moisture control and drying while naming the moisture source.
