Townhome blocks and shared plumbing stacks
Commercial mold remediation
in Ajax.
In Ajax a great deal of the multi-unit work involves shared plumbing stacks running through townhome blocks, so a failure in one unit becomes several owners' problem at once. ASM documents the affected assemblies unit by unit, which matters when the cost has to be divided between owners and a corporation.

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.

Ajax buildings
need a local eye.
Ajax housing ranges from established neighbourhoods near the lake to newer inland subdivisions and townhomes. Wind exposure, roof ventilation, grading and shared plumbing assemblies can all influence where moisture appears.
