Mold Removal, Remediation & Testing Griswold, CT

Chronic humidity, a sump failure, or seepage through the slab edge and foundation wall keeps a basement damp enough for mold to spread across concrete, framing, and stored belongings. On finished basements the same moisture colonizes the back of drywall and the wall cavity long before any stain reaches the room.

Our crews set sealed containment with negative air pressure and HEPA-filtered air scrubbers, then remove or HEPA-clean the affected materials and treat the foundation wall and framing with an EPA-registered antimicrobial per IICRC S520. The moisture source, seepage, a failed sump, or high humidity, is corrected and dehumidification is set before anything is closed back up.

Third-party ACAC air sampling confirms spore counts at or below the outdoor baseline before reconstruction begins. Every scope line, containment photo, and lab report is documented for your insurer so the claim moves on evidence.

Bathroom fans that terminate into the attic, blocked soffit ventilation, or a roof leak let warm moist air condense on cold roof sheathing. The trapped moisture feeds black streaking across rafters and plywood, often hidden until an inspection or a sale forces the issue, while spores drift down into the bedrooms below.

We build containment at the attic access, run HEPA-filtered negative air, and treat or remove the affected sheathing and framing under IICRC S520. Where the source is a misrouted exhaust fan or a ventilation gap, we coordinate the correction so the condensation does not return, then replace contaminated batt insulation.

ACAC clearance sampling verifies the attic and the living space below return to a normal indoor mold ecology. The full file, scope, photos, and lab results, goes straight to your adjuster for a clean review.

When humidity or a covered water loss reaches a forced-air system, mold colonizes the coil, plenum, and the sheet-metal walls of the supply and return ducts. Every cycle then pushes spores through the registers into rooms far from the source, which is why a duct system can spread a small problem across an entire floor.

We isolate the system, set HEPA-filtered negative air, and clean the coil, plenum, and accessible ductwork on a NADCA ACR aligned scope, applying an EPA-registered antimicrobial per IICRC S520 to affected surfaces. Contaminated porous components are removed rather than wiped, and the moisture driver is corrected before the system is restarted.

Post-remediation ACAC air sampling confirms the system and the conditioned space are back at or below the outdoor baseline. Documentation and lab reports are delivered for direct submission to your carrier.

A slow plumbing leak or a wet exterior wall can soak the back of sheetrock long before any stain reaches the room. Stachybotrys and other black molds colonize the wet paper facing and framing inside the cavity, so the growth spreads behind a wall that still looks clean from the living side.

Our crews set sealed containment with negative air pressure and HEPA-filtered air scrubbers, then open the affected cavity and physically remove contaminated drywall, insulation, and trim back to a clean substrate. Framing is treated with an EPA-registered antimicrobial per IICRC S520, and the moisture source is corrected before anything is closed back up.

Third-party ACAC air sampling confirms spore counts at or below the outdoor baseline before reconstruction begins. Every scope line, containment photo, and lab report is documented for your insurer so the claim moves on evidence.

In offices, locations, and other commercial buildings, a roof or plumbing leak above the drop-ceiling grid keeps tiles, deck, and overhead ductwork damp enough for mold to spread out of sight. Left alone, every HVAC cycle then carries spores across the floor and puts both occupants and business continuity at risk.

We scope the work around your hours, set sealed containment with HEPA-filtered negative air, and remove contaminated ceiling tile and porous material rather than wiping it. The grid, deck, and affected ductwork are treated with an EPA-registered antimicrobial per IICRC S520 on a NADCA ACR aligned scope, and the leak source is corrected before close-up.

Post-remediation ACAC air sampling confirms the space is back at or below the outdoor baseline before reoccupancy. The full file, scope, photos, and lab reports, is documented for your insurer and your property manager.
