A deep clean goes well beyond a regular clean: built-up grease in the kitchen, limescale on taps and screens, skirting boards, door frames, switches and the corners that get missed week to week. It works for a lived-in home as well as an empty one.
People book a one-off deep clean before a family visit, after a long winter, before selling or when a regular cleaner hasn’t kept on top of things. Landlords use it between tenants and homeowners as a reset. Every booking is covered by our 72-hour guarantee: if something isn’t right, tell us and we’ll put it right.

“Tenancy Cleaning sorted me out an urgent appointment and did the work needed at a high level, they were also polite and personable. This is the second time that I have used them and off the back of their quality work, I have asked about a regular booking which we are working towards. I thoroughly recommend.”

Yes. Most of our deep cleans are in lived-in homes. Clear worktops and floors where you can so the team can reach everything.
How far ahead should I book?
Most customers book 3–7 days ahead; we can often fit in sooner. Our busiest months are July and April, so allow a little longer then.
