Regular cleaning maintains a home that's already in good shape. It covers the surfaces you use every day: counters, sinks, toilets, showers, floors, and visible dust. Done on a steady schedule, it keeps build-up from forming in the first place.
Deep cleaning removes the build-up that's already there. It reaches places regular cleaning doesn't touch: baseboards, door frames, cabinet fronts, vents, ceiling fans, the inside of appliances, and grout lines. It takes longer, and the difference is visible.
Book a deep clean if it's your first professional cleaning, if it's been a few months since the last one, before or after hosting family, or at the change of seasons. Book regular cleaning once the home is in good shape and you want to keep it that way.
The most common approach is to start with a deep clean, then move to a regular schedule. Either way, ask your cleaner for the checklist, so you know exactly what's included before the visit.
