By the time you see mold on a wall in Merrimack, the colony behind it is usually ten times larger. Mold needs moisture, warmth, and organic material — NH's climate provides two for free. 24/7 Water Damage does remediation the right way: containment, HEPA filtration, safe removal, antimicrobial treatment, and third-party air testing.
Our Mold Remediation Process
Assessment & Testing
Visual inspection plus moisture mapping identifies the scope. We recommend a third-party air test before remediation starts — independent testing keeps the process honest.
Containment & HEPA Filtration
Negative air containment is non-negotiable. We seal the work zone, run air machines that pull air inward, and filter everything through HEPA. This prevents cross-contamination.
Remediate & Treat
Mold-colonized materials are removed through the containment seal and bagged for disposal. Remaining structural surfaces get HEPA-vacuumed and treated with professional antimicrobials.
Clearance Testing
An independent industrial hygienist collects air samples after remediation. When results come back within normal range, we sign off. We don't test our own work — that's a conflict of interest.

About Our Merrimack Mold Remediation Services
Our mold process starts with containment. We seal the affected area with 6-mil poly sheeting and run negative air machines to keep spores from spreading. HEPA scrubbers run continuously. Then we remove colonized drywall, insulation, and carpet through a sealed path. All removed materials go into sealed disposal bags.
We recommend independent mold testing before and after remediation for baseline data and verification. We refer qualified industrial hygienists in Merrimack. Post-clearance air testing is the gold standard for confirming the job worked. Call (866) 993-3605 to schedule a free assessment.
