Derry's climate feeds mold. Hot days, humid air, monsoon moisture — add a slow leak behind a wall or an AC condensate drip and you've got a problem. 24/7 Water Damage has done mold remediation in Derry for 15 years following IICRC S520 standards. We don't sign off until third-party air samples clear.

Our Mold Remediation Process

1

Identify the Problem

Visual inspection plus moisture mapping identifies the scope. We recommend a third-party air test before remediation starts — independent testing keeps the process honest.

2

Containment & HEPA Filtration

Full containment with negative air pressure prevents mold spores from reaching clean areas. HEPA scrubbers run continuously. Our crew enters and exits through sealed openings only.

3

Remediate & Treat

Contaminated materials removed, surfaces treated, and the moisture source fixed. We use Concrobium and Bio-Cide at professional concentrations — not household products.

4

Post-Remediation Testing

Third-party air testing confirms remediation was successful. We don't release containment until clearance testing passes. Your results come from an independent lab, not from us.

Why Choose 24/7 Water Damage for Mold Remediation?

Independent Verification

We recommend third-party air testing before and after remediation. We don't test our own work. Independent clearance testing proves the job was done right.

Find the Source

Killing mold without fixing the moisture source is a waste of money — it grows back. We find the leak, the condensation issue, or the ventilation problem and fix it as part of the job.

15 Years of Mold Work in Derry

NH's climate creates constant mold risk. We've been handling it in Derry for 15 years. We know which species are common here and the conditions that cause them.

IICRC S520 Protocol

We follow IICRC S520 mold remediation standards on every job — containment, HEPA filtration, safe removal, antimicrobial treatment. Not a simplified version. The real protocol.

Mold Remediation FAQ

Common signs: musty odor, visible discoloration on walls or ceilings, recurring allergic symptoms, or recent water damage that wasn't dried properly. We offer free visual assessments — call (866) 993-3605 and we'll take a look.

A typical residential job in Derry takes 2-5 days depending on the scope. Small bathroom or closet — 1-2 days. Multi-room or crawl space — up to a week. Add time for independent testing results.

Not if we fix the moisture source. Mold needs moisture to grow. We identify and address the water intrusion that caused the problem — fix the leak, improve ventilation, whatever is needed. No moisture, no mold.

About Our Derry Mold Remediation Services

After removing visible mold and colonized materials, we treat all remaining framing, concrete, and structural components with professional antimicrobials — Concrobium for prevention and Bio-Cide for active treatment. Surfaces get HEPA-vacuumed before and after. We also fix the moisture source, because killing mold without stopping the leak means it returns.

We recommend independent mold testing before and after remediation for baseline data and verification. We refer qualified industrial hygienists in Derry. Post-clearance air testing is the gold standard for confirming the job worked. Call (866) 993-3605 to schedule a free assessment.
