Sure, for roofing jobs or other large repairs, that’s true. But for remodeling it’s pretty different.

When I’ve engaged with a contractor for remodeling, I usually have some vague idea like “we should do something about this porch and deck and we’d like it to look nice.”

The contractor then talks to you about _requirements_, _options_, and _costs_. They then charges for architectural plans and the option to proceed with a budget and rough timeline.

Then they discover problems (perhaps “legacy construction”) and the scope creeps a bit.

And often the timeline slips by weeks or months for no discernible reason.

Which sounds exactly like a lot of software projects. But half of your house is torn up so you can’t easily cut scope.
