Preston's light industrial buildings get refitted rather than replaced, and a refit produces a specific debris mix: old racking, adhesive residue on slab, and dust in structure that was never sealed. It cleans nothing like a new build, and it should not be quoted like one.
About Preston
Preston is a former mill settlement at an I-90 exit between Issaquah and Snoqualmie — a few dozen houses, some light industrial buildings, and not much else. Its value to a cleaning schedule is position: it sits exactly on the road between two cities we already serve, so a Preston stop costs almost nothing in travel if it is booked alongside them.
What post-construction cleanup covers
Post-construction is the only cleaning job with a deadline somebody else set. The certificate of occupancy, the tenant walkthrough, the open house — the date is fixed before we are called, and the clean is the last thing standing between the building and the people waiting for it.
Heritage does the full sequence: rough clean once the trades are out, then the final detail that actually gets inspected. Drywall dust out of tracks and returns, adhesive and sticker residue off glass and fixtures, paint flecks off hardware, and a floor that has been gone over enough times that it stops producing dust.
Priced per square foot after a walkthrough, with a $450 project minimum. Terms are Net 15. We quote the scope we can actually finish before your date rather than the number that wins the job and misses it.
Ideal for
- General contractors closing out a build

Common questions
What is the minimum?
$450 per project. Below that the mobilisation costs more than the clean, and quoting under it would mean cutting the final detail — which is the part that gets inspected.
Do you do the rough clean and the final, or only one?
Either. Many contractors book both: a rough clean once the trades are out so the space can be worked in, then the final detail closer to the handover date. Booking both is usually cheaper than one heroic pass at the end.
Can you hit our certificate of occupancy date?
We will tell you honestly at the walkthrough. If the date does not leave room for the scope, we say so before you book rather than after. That is worth more to you than an optimistic yes.
Do you carry insurance for an active job site?
Yes. WA Contractor License HERITBS745D6 and $2,000,000 general liability aggregate through Farmers. We send the certificate to your GC or property manager before the first day on site.
