Multi-unit mold work: shared areas and access
Mention common walls, service shafts and rooms above or below the concern. Also, record any recent leak reports. However, avoid treating a unit boundary as proof that damage stops there; the actual extent needs review.
Agree on communication and entry
For multi-unit cleanup, first choose a contact who can coordinate occupants and contractors. Next, confirm appointment times and the route for tools or materials. As a result, written arrangements reduce confusion when more than one person is responsible for access.
Keep separate scopes easy to follow
In a multi-unit cleanup scope, ask what belongs to the unit work and what requires building approval. Also, keep findings, quotes and change decisions together. Finally, confirm who will receive the completion record and handle any remaining moisture repairs.
