Almost every call starts with the same question, usually phrased as a worry: do I need the expensive one? The honest answer is that the two services do different jobs, and most homes need both at different times.
Basic cleaning is maintenance. Floors vacuumed and mopped, bathrooms scrubbed, kitchen surfaces wiped, dusting, beds made, trash out. It is designed to be repeated on a schedule, and its whole purpose is to stop dirt from ever building up. In a house that gets cleaned regularly, it takes a predictable amount of time and costs a predictable amount of money.
Deep cleaning is recovery. It goes after everything a maintenance visit deliberately skips because there is no time for it every week: baseboards and door frames, the tops of cabinets, inside the oven and refrigerator, shower grout and door tracks, blinds, vents, ceiling fans, and the grime behind the toilet. It takes several hours and it is priced for that.
Here is the simple test. Run a finger along the baseboard behind a piece of furniture and look at the tops of the door frames. If either one surprises you, the house needs a deep clean before a routine can hold. If both are fine, basic cleaning on a schedule is all you need.
The pattern that works for most Marietta homes is one deep clean at the start, then basic visits every week or two after that. The first visit resets the house; everything after that keeps it there, which is both cheaper and less disruptive than a big clean twice a year.
One more thing worth knowing: if it has been more than a year since a full clean, tell whoever quotes the job. A deep clean priced on a phone description and a deep clean priced after somebody has actually seen the house are two very different numbers, and only one of them holds.
