When Portsmouth homeowners and business operators deal with mold, they need a company that knows the area, shows up fast, and gives them a binding written price before touching anything. That's Business Leak Detection. Our certified crews serve Portsmouth and surrounding NH communities with the same standard on every job — IICRC S520 protocol, written flat-rate pricing, and a satisfaction guarantee in writing.
Every Portsmouth project starts the same way: a live person answers when you call, certified crew dispatched fast, thorough inspection with documented findings, written estimate you sign before work starts, and a job that closes only when post-clearance air testing confirms success.
Here's the full Portsmouth service lineup.
Every Portsmouth emergency call gets same-day response as the operational standard. We don't send a technician to "assess and schedule" — our crews arrive with everything needed to begin containment and remediation on the first visit.
HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Portsmouth emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
We find every affected area in your Portsmouth home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.
After inspection, you receive a complete written itemized estimate for your Portsmouth project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Portsmouth area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Portsmouth commercial inspection as standard.
Post-remediation verification reports are provided on every Portsmouth commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-323-329-3586 for a Portsmouth commercial site assessment.
Not sure if your Portsmouth property has an actionable mold problem? Our inspection delivers documented answers — calibrated air sampling through certified labs, thermal imaging, moisture mapping, and surface swabs to build a complete picture before any remediation is recommended.
Written report delivered within 24 to 48 hours of the Portsmouth site visit. Call +1-323-329-3586 to schedule.
Toxigenic mold species — particularly Stachybotrys — appear in Portsmouth properties with histories of water damage or chronic moisture. They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Portsmouth black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Portsmouth property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Prevention services for Portsmouth properties include crawl space encapsulation, vapor barrier installation, dehumidification system design, ventilation assessments, and structural moisture intrusion identification.
Our optional maintenance program for Portsmouth customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

Homeowners and business operators in Portsmouth — real testimonials from people who called Business Leak Detection when mold became a real problem.
We were buying a home in Portsmouth and mold showed up on the inspection report two days before closing. I called Business Leak Detection in a panic. They came out the next morning, knocked it out in 48 hours, and we had the clearance report in time for the lender. Deal closed. I've already recommended them to two friends in Portsmouth.
My Portsmouth restaurant was flagged for mold during a health inspection. Called Business Leak Detection that morning. Crew on-site by noon, affected prep area contained without shutting down the full kitchen, clean clearance report before my reinspection. Saved us from a week-long closure. They understood exactly what was at stake.
Two years of musty smell in our Portsmouth basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Business Leak Detection removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
