Access and existing conditions
Tight stairwells, occupied rooms, height, slope, landscaping, and how much finish protection is needed all affect labor time and sequencing.
Scope and materials
Where repair boundaries fall, system capacity, material compatibility, disposal, testing, and restoration work should all be spelled out, not implied.
Permits and outside expertise
Some scopes require permits, inspections, engineering review, environmental testing, or a specialty trade — confirm which apply with the provider and the local authority.
Nothing here is an offer. Get a written, property-specific scope before treating any number as real.
