Mold Removal & Remediation

Attic mold on roof sheathing, basement mold behind finished walls, bathrooms and behind the drywall growth. We find the moisture source, seal the work area under negative air, remove affected material, treat what stays, and HEPA-clean on the way out.

Attic Roof Sheathing

Mold staining across plank sheathing, taken back to clean bare wood. Attic growth like this is usually a ventilation fault a bath fan or soffit dumping warm wet air into a cold roof space.

Attic Clean-Up & Re-Vent

Old ducting pulled out, the roof deck cleaned down, and a new insulated duct run properly to outside. Fixing the venting is what stops it coming back.
