The most common disappointment in this trade is a customer who booked a regular clean, got exactly what a regular clean covers, and expected a deep clean. Nobody did anything wrong — the two services just do different jobs, and the words do not make that obvious. So here is the difference in plain terms, and how to work out which one your home actually wants.
A regular clean maintains. It assumes the house is broadly in order and keeps it there: kitchens and bathrooms cleaned properly rather than wiped, floors vacuumed and mopped throughout, surfaces dusted, beds made, bins emptied. It follows the same checklist every visit, which is what makes it fast and what makes it reliable. On a weekly or bi-weekly plan it is the cheapest way to keep a home genuinely clean, because nothing is ever allowed to build up in the first place.
A deep clean goes after the build-up. Inside the oven and under the burners, where baked-on grease does not come off with a cloth. Behind and beneath the fridge and the washing machine. Grout scrubbed rather than mopped over. Shower glass descaled. Extractor hood filters degreased. Baseboards, door frames, radiators and vents by hand. Light fittings and ceiling fans taken down and wiped. Window interiors and sills. It takes a team most of a day, and there is no version of a two-hour visit that includes it.
The test is simple: look at the parts of your home nobody has cleaned in a year. Run a finger along the top of a door frame. Open the oven. Look at the grout line where the tile meets the tub, and at the seal on the shower glass. Pull the fridge out a few inches. If any of those make you wince, a maintenance visit will not fix them — it was never meant to. That is a deep clean.
The other thing worth knowing is the order they go in. If a home has not been cleaned professionally for a while, a deep clean first and a maintenance plan after is both cheaper and better than a run of regular visits trying to catch up. Each regular visit can only hold the line; it cannot claw back three years. Once the deep clean has reset it, a fortnightly visit keeps it there indefinitely, which is why we price the two together.
There are also moments that call for a deep clean regardless of schedule: before a new maintenance plan starts, after building work or decorating, at the end of a winter with the windows shut, before hosting, and any time a home changes hands. Most households find once or twice a year is right, with regular visits in between.
