Because everything on Mercer Island is within a few minutes of everything else, a nightly janitorial contract here costs less to run than in almost any city we serve — the travel between stops is nearly zero once a crew is on the island. That efficiency belongs in the quote, not in our margin.
About Mercer Island
Mercer Island is a single island with one commercial core and everything else residential, which makes it unusually easy to schedule: once a crew is on the island, every stop is within a few minutes of the last. The housing runs from mid-century homes near the north end to large newer builds along the water, and the town center holds the offices, clinics, and shops that make up the commercial work.
What janitorial services covers
Janitorial work is the difference between a building that is cleaned and a building that stays clean. It is the same scope, week after week, executed by people who know the property well enough to notice what changed.
Heritage takes on recurring janitorial contracts for offices, medical suites, schools, and multi-tenant buildings. You get a written scope, a fixed schedule, and a point of contact who is the owner of the company — not a dispatcher three states away.
When something needs escalating — a supply order running low, a floor that is due for a refinish, a leak nobody reported — you hear about it from us before it becomes a work order.

Common questions
What is the difference between janitorial and commercial cleaning?
Commercial cleaning can be a one-time or occasional job. Janitorial is a standing contract: the same agreed scope, on a fixed schedule, with the same crew. If your building needs upkeep rather than a reset, this is the one.
Is there a minimum contract length?
We do not lock clients into long contracts. Most janitorial accounts run month to month after a walkthrough and a trial period, so you can adjust the scope once you see how the building actually uses it.
Who do we call if something is missed?
You call Doraneli directly. Heritage is small on purpose — the person who quoted your building is the person who answers when something needs fixing.
Do you handle supply restocking?
Yes. Paper goods, soap, and liners can be included in the contract, or we can simply restock what you buy. Either arrangement is spelled out in the written scope.
