Right after price, every Oʻahu homeowner asks the same thing: how long will I be living around a construction zone? Here's a straight answer. A single-family bathroom remodel typically runs 7 to 15 days on site. A complex master suite runs 3 to 4 weeks. A kitchen varies more than either, because its timeline is driven by structural scope. But on Oʻahu, the honest number isn't just the days the crew is in your house — it's the lead time before they ever arrive.
Typical build windows, in plain days
These are on-site build windows for single-family homes — not condos, not commercial work. The range inside each one comes down to how much tile you're setting and whether the layout stays put or moves.
- A standard single-family bathroom — 7 to 15 days on site, depending on tile scope and whether fixtures stay in place or relocate.
- A complex master suite — 3 to 4 weeks, with more fixtures, more tile, and often a plumbing or structural change that adds days.
- A kitchen — the widest range of all, because a like-for-like refresh is a completely different job than opening a load-bearing wall to the living room. Structural scope sets the clock.
The part the mainland forgets: ocean lead time
On the mainland, a cabinet order shows up in a couple of weeks. On Oʻahu, cabinetry, tile, stone, and fixtures ship across an ocean — and a backordered vanity or a custom slab can add weeks that have nothing to do with how fast the crew works. Permitting runs on the same reality: structural changes go through the City & County of Honolulu's Department of Planning and Permitting (DPP), and that review takes real time. A contractor who prices and schedules as if this island were Phoenix is the one who blows past the finish date.
What a disciplined schedule actually looks like
We build the schedule backward from those realities instead of pretending they don't exist. Long-lead materials get ordered and staged before demolition begins, so the crew is never standing around waiting on a slab that's still on a barge. Permits are pulled as part of the timeline, not bolted on after the fact. And when we commit to a start date, we hold it — the military discipline behind this company (Marine Corps and Air Force) means the calendar is something we run, not something that runs us. Real start dates, held, is the whole point.
Hidden conditions, and the honest contingency
Older Oʻahu homes hide surprises behind the drywall: dated wiring, failed plumbing, moisture or termite damage that no one can see until demo opens the wall. A found condition can add days to any of the ranges above. We'd rather scope that possibility honestly up front and build a little contingency into the plan than hand you a date we already suspect the walls might break. A schedule you can trust is one that accounts for what Oʻahu homes actually hide.
