What changes the labor
Rotted sill hidden under clapboard, tight second-story access, occupied rooms, and steep gables all add time to a Washtenaw County job.
What should be spelled out
System capacity, material match to the existing trim, disposal, and finish restoration need to be explicit, not assumed.
When specialists get involved
Historic-district homes, older lead-paint trim, or structural rot may call in permits or specialty trades. Confirm locally.
For planning only
Nothing here is a quote. Ask the matched provider for a written, property-specific number.
