It is the first question almost every homeowner asks, and the honest answer is: it depends. But "it depends" is not very helpful when you are trying to plan your life around a project. So here are realistic ranges and the factors that actually move them.
Rough timelines by project
These assume a clear scope, normal permitting, and no major surprises. Every home is different, but they are a useful starting point:
- Bathroom remodel: roughly 2 to 4 weeks.
- Kitchen remodel: roughly 4 to 8 weeks, longer if cabinets are custom.
- Whole-home renovation: roughly 3 to 6 months or more.
- Additions and new square footage: roughly 4 to 8 months, since permitting and structural work add time up front.
What stretches a timeline
When a project runs long, it is usually one of a few culprits: permits and inspections that move on the city's schedule, custom or long-lead materials that have to be ordered weeks ahead, and structural surprises that older homes love to hide behind a wall. Change orders mid-project and weather (for anything exterior) add time too.
What keeps it on schedule
The projects that finish on time tend to share three things. First, a detailed written scope and quote, so nobody is improvising once the work starts. Second, ordering materials early, before they become the bottleneck. Third, one accountable team coordinating every trade, so a delay in one area does not stall everything else.
The bottom line
A good contractor will give you a realistic timeline before the first wall comes down, flag the likely unknowns, and keep you updated as the project moves. Beware anyone who promises a suspiciously fast finish with no caveats. A clear plan beats an optimistic guess every time.
