Ask ten cleaning companies how often you should deep clean your house and you'll get ten answers, most of them suspiciously aligned with selling you more cleans. So here's our actual take, after thousands of Edmonton homes: twice a year is the minimum for almost everyone, and your household decides whether it's two, three, or four.
Start Here: The Twice-a-Year Baseline
Deep cleaning targets what regular cleaning doesn't touch — baseboards, grout, appliance interiors, blinds, vents. Even in the tidiest home, that stuff accumulates. Twice a year (spring and fall work naturally in Edmonton) keeps it from ever becoming a project. If you're not sure where you fall, start here and adjust. Not sure what a deep clean even covers? Our deep vs standard guide lays it out.
Your Household Type Changes the Math
Kids under 10: three to four times a year. Sticky is a lifestyle. Baseboards, walls at hand height, and floors take a beating that no maintenance clean fully addresses.
Dogs (especially big shedders): three to four times a year. Hair works into places you'd never expect — under appliances, into vents, woven into upholstery. Huskies and shepherds, we're looking at you.
Cats: twice a year is usually fine, unless litter tracking is an issue, in which case add a third.
Allergy or asthma sufferers: three to four times a year, timed before your worst seasons. Dust mites, pollen tracked indoors, and pet dander all live in the deep-clean zone.
Single professional, no pets: twice a year is plenty, honestly. Maybe once if you're genuinely tidy.
Seniors or anyone with limited mobility: three times a year. The high, low, and behind things get neglected when bending and reaching are hard — that's exactly what we're for.
Edmonton Factors That Speed Up the Clock
- Winter salt (November–March). Five months of grit grinding into entryways, mudrooms, and hard floors. A spring deep clean isn't optional here; it's recovery.
- Wildfire smoke season. Bad smoke summers leave fine particulate on every surface and in HVAC systems. If we had a smoky August, your fall deep clean matters more.
- Spring melt. The muddy weeks of March/April punish floors and entryways. Homes without a spring reset carry that grime all summer.
- Newer, larger homes. Summerside, Windermere, Terwillegar — bigger footprints mean more surface area collecting dust between cleans.
Signs You're Overdue
Run your finger along a baseboard. Look at the grout in your shower versus the grout behind the toilet (nobody cleans there). Check the top of the fridge. If any of those made you wince, you're overdue — and that's fine, it's literally what deep cleaning is for.
What Happens If You Just Skip It
Nothing dramatic — and that's the trap. Skipped deep cleaning doesn't cause a crisis; it causes a slow slide. Grout darkens so gradually you stop seeing it. The oven gets a little worse each month until "self-clean" can't save it. Allergies creep up and get blamed on the season. Then one day you notice all of it at once and the job feels enormous. The cost of skipping isn't a single disaster, it's that the eventual deep clean takes longer (and costs more) than two routine ones would have. Steady beats heroic, every time.
How Often to Deep Clean: Building It Into a Routine
The lowest-effort approach: one deep clean each spring and fall, plus a recurring standard plan in between (bi-weekly is the sweet spot for most households, and it saves 15%). The deep cleans reset; the recurring visits maintain. Your home never slides, and you never face a dreaded whole-house scrub again.
Put It on the Calendar Now
The best schedule is the one you'll actually keep, so make it concrete: pick your two months (we suggest May and October for Edmonton) and book them like appointments. Tie the spring one to something memorable — the first weekend you open windows, or right after the street sweeping. Tie the fall one to furnace-filter season. Once it's a habit, you'll stop thinking about deep cleaning entirely, which is rather the point. And if life gets in the way and you skip one, don't do a guilt-spiral — just book the next one. Your baseboards will forgive you. When in doubt, err on the side of one extra deep clean a year — it's always cheaper than letting things slide until the job doubles.
