From sheathing assessment through fan rerouting and ventilation correction — the full above-ceiling mold scope for Winter Garden, FL properties.
Assessment
🔍Sheathing Assessment & Sapstain Distinction
MC% at multiple points, section-by-section growth characterization, structural assessment for delamination. Lab sampling where species or activity status isn't clear from visual and moisture data alone.
Ventilation
💨Soffit Vent Clearance & Ridge Vent Assessment
Eave bay clearance and baffling, ridge vent condition assessment, vent addition where NFA is insufficient. All specified in the written scope with the reason for each correction.
Fan Rerouting
💨Exhaust Fan Rerouting to Exterior
Bathroom fans, kitchen fans, and dryer vents identified as terminating inside the Winter Garden, FL attic are rerouted to the exterior — through gable, soffit, or roof cap — using properly insulated flex duct or rigid metal, sealed at the fan housing and at the exterior penetration. This is typically a same-day correction.
Treatment
🌳Borate Treatment & Encapsulant Application
EPA-registered penetrating borate applied to all accessible sheathing and rafter surfaces after HEPA vacuuming of loose spore material. Optional mold-resistant encapsulant applied over borate-treated surfaces where additional barrier protection is warranted — typically on south-facing or warm-roof sections with historically higher moisture loads.
Replacement
🔨Sheathing Replacement Where Structurally Needed
OSB and plywood sheathing sections with confirmed structural delamination, loss of rigidity, or through-penetration of decay fungi are flagged for replacement in the written scope — individually assessed rather than assumed. Replacement work coordinated with roofing contractor when the roof covering must be removed for access.
Clearance
✅Post-Remediation Clearance & MC% Verification
MC% re-check plus independent air sampling inside attic and below. Written clearance report confirms remediation achieved its objective and ventilation corrections are working.
