Access and existing conditions
Occupied rooms, tight access, stairs, height, slope, landscaping, and finish protection all factor into labor and sequencing.
Scope and materials
Where the repair boundaries sit, system capacity, material compatibility, disposal, testing, and restoration should all be explicit in writing.
Permits and specialty input
Some projects require permits, inspections, engineering review, environmental testing, or a specialty trade — confirm which with the provider and the local authority.
For planning, not pricing
Nothing here is an offer. Ask for a written, property-specific scope before treating any figure as real.
