A deep clean is usually booked before a regular schedule starts, after a house has been empty for a while, or when things have built up and a normal visit won’t touch it. It goes further than a weekly clean: the oven gets properly degreased inside, not just wiped round the door, grout lines in the bathroom and kitchen are scrubbed rather than left grey, and appliances like the fridge and washing machine are moved where it’s safe to do so and cleaned behind and underneath.
Limescale around taps and shower screens gets treated properly rather than papered over with a quick spray, and skirting boards, radiators and light fittings are included throughout, not just in the rooms that show. Most one-off deep cleans in Boston take a full day for an average three-bedroom house, sometimes longer if it’s been a while since the last proper clean.
From £90, depending on the size of the property and how much needs doing. A quick look round beforehand means the quote is accurate, not a guess.
