Once a year is the floor. A San Jose home with steady weekly upkeep and no complicating factors genuinely holds twelve months between deep cleanings — and a home with pets, kids, allergies, hard water, or a kitchen that earns its keep almost never does. So the schedule we actually recommend has two settings: once a year for the quiet house, twice for the working one. Here's how to tell which one you live in, and where to put the dates.
(This assumes you know what a deep cleaning is — the baseboards-and-buildup service, not the weekly reset. If the line between the two is fuzzy, the full anatomy lives here → Regular Cleaning vs. Deep Cleaning: Which One Does Your Home Need? — come back for the when.)
What moves you from once to twice
Pets. Dander and hair don't stay on the floor — they ride air currents onto shelves, vent covers, and the tops of door frames, exactly the zones weekly cleaning skips. One shedding animal is enough to earn the second date on its own.
Kids at home. Fingerprints at knee height, food in rooms food never officially visited, and floors that live a harder life than the square footage suggests. A household with young children builds up at roughly double the childless rate.
Allergies or asthma. The dust that matters to sensitive lungs is the dust nobody wipes — ceiling fans, vents, behind and under furniture. If anyone in the house medicates through spring, book two, and put one of them in March or April.
Hard water. Santa Clara County water carries enough mineral to shadow grout and film shower glass within a few months, and scale left past the half-year mark hardens from a wipe into a restoration project. Two visits a year keeps bathroom scale in the easy category.
A kitchen that cooks. Nightly cooking — especially frying and high-heat searing — puts an oil mist in the air that settles as a film on cabinet faces and the wall above the stove. If you cook most nights, you're a twice-a-year kitchen whatever the rest of the house says.
None of these is a moral failing; they're just load. The house that hosts more life needs its reset more often.
Where the dates land
Booking once: spring. The deadline is pollen — the valley's grass and olive season loads every open window with dust that settles for months, so a deep clean at the front end of it clears winter's closed-window buildup and lets you start the season from zero.

Booking twice: add late fall. The second date goes before the holidays fill the house — guests, cooking marathons, and the annual audit performed by visiting relatives. The full pre-holiday logic → Getting Your Home Holiday-Ready (Without the December Scramble)
Spring clears what the year deposited; fall resets the house before it hosts. Between them, the two dates bracket exactly the seasons that load a home fastest.
The signs you're already overdue
The calendar is a guess; the house tells the truth. You're overdue when:
- Grout carries a gray shadow your own scrubbing doesn't lift
- Cabinet faces near the stove feel faintly tacky to a fingertip
- Dusting doesn't hold — surfaces are gray again within a day or two
- The house has a walk-in smell you only notice returning from a trip
- The "clean" after your regular clean no longer looks like it used to
Two or more of those, and the next deep cleaning shouldn't wait for its season. Buildup compounds — every month it sits, it bonds harder and costs more time to remove.
Carpet keeps its own calendar
Everything above is about the house's surfaces. Carpet runs a separate, faster clock — it's the home's largest filter, and it fills on footsteps, not seasons.

If your home has never had one
Then the question isn't frequency yet — it's sequencing: one deep cleaning to establish the baseline, then a schedule to hold it. That booking-order decision, including when the cheaper service is the right answer, lives here → Deep Cleaning or Regular Cleaning: Which Should You Book First?
And when your date comes up — or the overdue list just read like a description of your kitchen — the service and its plain-numbers pricing are both posted → Deep cleaning service · Deep cleaning prices
