Almost everyone asks the same question after their first deep clean: how often should we do this? The honest answer depends on four variables, and none of them is how much you want to spend.
Pets are the biggest single factor. Shedding animals put hair and dander back into a house continuously, and in Central Florida humidity that turns into visible film on hard floors within days. Homes with two or more pets are usually happiest on weekly service.
Kids are the second. Not because children are messier in principle, but because kitchens and bathrooms get used far more times per day, and those two rooms drive almost the entire perception of whether a house is clean.
Square footage matters less than people expect, and used square footage matters more. A four-bedroom home where two bedrooms are closed off behaves like a smaller house. Tell your cleaner which rooms are actually in play and the schedule can be lighter.
As a starting point: weekly for busy households with pets or young kids, bi-weekly for most families, monthly for couples, professionals, and anyone who is tidy by habit and mostly wants the deep-surface work handled. Whichever you choose, keep the checklist identical every visit. Consistency is what keeps a house from slowly drifting back.
