The #1 reason Boston walkthroughs get pushed: the GC called the cleaning crew too late. Here's the right scheduling window, the wrong one, and why 72 hours is the magic number.
The 72-hour rule.
The ideal timeline.
T-14 days
Quote requested, scope defined, date locked with cleaning crew. COI issued to PM or property owner.
T-7 days
Final punch walkthrough with your sub trades. Any trade that disturbs surfaces (painters, electricians, HVAC) done by now.
T-5 to T-3 days
Cleaning crew executes full scope — 1-3 days depending on square footage. On large jobs, they start with dust/vacuum, move to wipe-downs, finish with detail + windows.
T-3 to T-1 days
Buffer. Any punch items from PM walkthrough get fixed. Cleaning crew on-call for re-clean if needed. Do NOT schedule any dusty trade work in this window.
T-0: Walkthrough day
Client arrives to a space that looks like a finished product, not a construction site that got dusted off that morning.
What goes wrong with late bookings.
- Crew unavailable. Good post-con crews are booked 5-14 days out. Calling 48 hours before walkthrough often means you get whoever's available — usually the wrong crew.
- Rush surcharge. 24-hour turnaround: +25-40%. Same-day: +50-75%. Half the GCs we quote in a rush end up paying 2x what they would have paid 2 weeks out.
- Paint and trim still curing. Fresh paint (<48hrs old) can't be wiped hard. Rushed cleaning = streaks, fingerprints, missed dust.
- No re-clean buffer. Something always gets missed on post-con — that's why the re-clean guarantee exists. Zero buffer = walkthrough delay when the PM finds a single grout haze spot.
What goes wrong with too-early bookings.
Booking too early is rare, but it happens — especially on commercial jobs where the schedule slips:
- Trim installers come back to fix punch → fresh dust settles everywhere.
- HVAC tech needs a final damper adjust → dust drops from ceiling.
- Flooring touchup → sawdust on clean floors.
- Client walkthrough gets pushed 2 weeks → space re-accumulates residential dust.
Rule: never schedule post-con cleanup if trades are still disturbing surfaces.
The residential difference.
For homeowner jobs (especially in Newton, Brookline, Wellesley), the timeline is often tighter because move-in day is hard-set:
- T-5 to T-2 days — cleaning scheduled before moving truck arrives
- Re-clean buffer typically shorter — 24-48hrs
- We often scope residential jobs in 1 day — 2-3 person crew, 6-10 hour shift
Commercial + medical add time.
Office fit-outs, lab suites, medical offices — plan for longer cleaning windows:
- Commercial 5,000-15,000 sq ft: 2-3 day cleaning scope
- Medical / lab clean-room grade: 3-5 days
- Multi-floor retail: scaffolds, lift rental, 3-7 days
The takeaway.
- Quote at T-14 days minimum.
- Execute cleaning T-5 to T-3 days from walkthrough.
- Leave a 48-72hr buffer.
- Do not disturb finished surfaces after cleaning.
- If schedule slips, call immediately.
