Deep Cleaning Calgary —
Hard Water Specialists
Calgary's tap water runs at 200–250 mg/L of calcium and magnesium — some of the hardest in Canada. We follow a documented method — top to bottom, left to right, no exceptions — then go where a regular clean doesn't: inside every appliance, inside every cabinet, and directly after mineral deposits with our acid-based hard water protocol.

Why Calgary hard water is a cleaning problem no one talks about
Calgary's municipal water supply consistently measures 200–250 mg/L of dissolved calcium and magnesium. That's well above the 120 mg/L threshold that water quality labs classify as "hard." Every time water evaporates on your shower glass, faucet, or chrome fixture, it leaves mineral residue behind. Over time, that residue calcifies into a white-grey scale that regular all-purpose cleaners cannot touch.
We use pH-adjusted, acid-based products specifically formulated to break the calcium-carbonate bond — applied with dwell time, not just wiped on. We never use these products on marble, granite, or natural stone, where acid causes irreversible etching. If your home has stone surfaces, we flag this before we begin.
Everything a regular clean does.
And then some.
A deep clean covers every task in our regular residential method — plus the areas that only get attention in a true reset: inside appliances, inside cabinets, grout, baseboards, and full hard water removal.

Deep cleaning FAQ
What's the difference between a deep clean and a regular clean?
A regular residential clean covers all rooms, surfaces, floors, bathrooms, and kitchen following our documented top-to-bottom method. A deep clean adds: inside every appliance (oven, fridge, microwave), inside cabinets, grout scrubbing, full calcium removal from shower glass and chrome, baseboards fully wiped (not just dusted), and areas behind and under furniture. Most clients who haven't had a professional clean in 3+ months should start with a deep clean, then switch to regular maintenance.
How does Calgary hard water affect my home — and what do you actually do about it?
Calgary's tap water measures 200–250 mg/L of dissolved calcium and magnesium — well above the 120 mg/L threshold that classifies water as "hard." Every time water evaporates on a surface, it deposits a thin layer of mineral residue. Over months, that residue calcifies into white or grey scale that standard cleaners cannot dissolve. We pre-treat affected surfaces (shower glass, chrome, faucets, tile grout) with pH-adjusted acid-based products and allow them to dwell before wiping. This is included in every deep clean — not an add-on. Note: we never apply acid products to marble, granite, or other natural stone, where they cause irreversible surface damage.
How often should I schedule a deep clean in Calgary?
For most Calgary homes, we recommend a deep clean every 6–12 months, even if you have regular cleaning in between. Calgary's hard water means calcium deposits build up faster here than in most Canadian cities. If you're starting regular maintenance with us, we recommend a deep clean as your first visit — it resets the home to a clean baseline that's much easier to maintain thereafter. If you've recently moved in, just finished a renovation, or had a gap in professional cleaning, a deep clean is the right starting point.
Do I need a deep clean before starting regular maintenance with SonderCleaning?
We always recommend it, though it's not mandatory. A deep clean as your first visit sets a consistent baseline — every surface thoroughly cleaned, appliances done, hard water removed. From that point, regular maintenance keeps the home at that standard efficiently. Starting regular visits on a home that hasn't had a deep clean often means the first few visits are playing catch-up rather than maintaining. Deep cleaning is $50/hr all-inclusive with a 3-hour minimum. Final rate depends on service type — see your exact price when you book.
How long does a deep clean take in Calgary?
Most 3-bedroom homes in Signal Hill, Aspen Woods, and Coach Hill take 4–6 hours for a full deep clean. Homes with heavy hard water buildup, multiple bathrooms, or a long gap since the last professional clean often run closer to 6–8 hours. We don't rush or cut tasks to fit an arbitrary time — we work until the job is done to our standard. We'll give you a time estimate when you book and update you if it looks like it'll run significantly longer.
