Post-Water-Damage Mold Remediation — Certified in St. John's
St. John's Restoration Co. provides certified mold remediation in St. John's, Newfoundland and Labrador. Certified mold remediation with negative-air containment, HEPA filtration, and third-party clearance testing — commonly needed after incomplete water damage drying. We provide complete insurance documentation and bill all major NL insurers directly — including Intact, Aviva, and TD Insurance.
Mold is the predictable consequence of water damage that wasn't properly dried — or wasn't addressed at all. In St. John's NL, the combination of high ambient humidity, a significant proportion of older housing stock, and a wet climate means mold remediation following water damage or flooding events is one of our most frequent calls.
St. John's Restoration Co. provides full certified mold remediation: containment with negative air pressure, HEPA air filtration during all work, controlled demolition of affected porous materials, antimicrobial treatment of remaining structural surfaces, and third-party clearance air testing.
We identify and correct the moisture source before remediation begins. Without this step, mold returns regardless of how thoroughly it was removed. Our comprehensive documentation supports insurance claims, satisfies NL real estate transactions, and gives you a permanent record of the work.
