In Carnation the deep clean people actually need after a wet winter is a post-flood reset, and that is a different scope than a spring clean. Water leaves silt in places nothing else reaches, and the honest sequence is to let the building dry first — cleaning a damp floor is work that has to be repeated.
About Carnation
Carnation sits on the Snoqualmie Valley floor, on farmland that floods most winters. That single fact drives the cleaning calendar: mudrooms and entryways take a beating from October through March, and properties near the river routinely need a post-flood reset rather than a routine visit. The town itself is a short commercial strip serving a few hundred households, so the commercial work here is a handful of small storefronts, a clinic or two, and the buildings the town runs out of.
What deep clean & sanitization covers

A deep clean is not a longer nightly clean. It is a different job: inside the appliances, behind the fixtures, the tops of partitions and door frames, the grout, the vent covers, the baseboards nobody has looked at since the space was painted.
Facilities book this after an illness runs through a staff, before an inspection or an audit, at the start or end of a lease, after a renovation, or when a building has quietly accumulated a year of ordinary use. It takes two to three times as long as a routine visit, and it is the honest starting point for a janitorial contract on a space that has been neglected.
Sanitization is quoted with it or without it. When it is included we use EPA-registered disinfectants applied for their full contact time and tell you which product went where, because a disinfection claim that cannot be named is not a claim worth paying for.

Common questions
How long does a deep clean take?
It depends on square footage and how long it has been. A small suite that is generally maintained might take four to six hours; a facility that has never had one can take a full day or more. We give you a realistic window after walking the space, not before.
Do we need a deep clean before starting a janitorial contract?
Usually, but not always. If the space is already in good shape we will start you on the routine schedule and save you the cost. We would rather hold an account for three years than win it with one oversold first invoice.
Is disinfection included or extra?
It is quoted as its own line so you can see what it costs and decide. Where it is included we apply EPA-registered disinfectants for their full dwell time and document which product was used where.
Can a deep clean remove hard water stains and old grout discoloration?
Often, substantially. Not always completely — mineral etching in glass and grout stained for years may improve without disappearing. We tell you what to expect before we start rather than after.
