Conditions and access
Century-old framing, converted-loft concrete, and occupied living space during the project can all add time before real work starts.
Scope and materials
A trustworthy proposal states plainly where the work starts and stops, what materials are compatible with the existing system, and how testing and cleanup are handled.
Permits and specialist input
Historic-district review, structural changes, or moved plumbing may all require permits and inspection. Confirm locally with the selected provider and the city.
Educational planning only
Nothing here is a quote — use it to sanity-check a written, property-specific proposal instead.
