Industrial units and tenanted commercial space
Commercial mold remediation
in Oshawa.
Oshawa commercial work runs from small tenanted storefronts to industrial buildings where the moisture is usually roof-related rather than plumbing. ASM inspects the roof assembly and the interior together, because for these buildings a remediation without a roofing referral just resets the clock.

ASM provides planned commercial remediation designed to contain affected areas, protect occupants and reduce downtime. Scope, access, sequencing and documentation are reviewed with the property contact before work starts so business operations can be coordinated safely.
