Hi EF,

Wondering if anyone knows a company that does a really great, deep clean for moving out?

Many thanks,
Louise

If they provide a "Abnahmegarantie" and are present at the hand over , you can take any company you like (depends on the money you are willing to spend)

FYI OP, "Abnahmegarantie" means that the company will clean the flat for as long as it takes for your landlord to be satisfied and accept the flat at the handover.
If you don't have this, the cleaning company can charge you for extra cleaning time/supplies etc. if the landlord isn't satisfied with their cleaning when he shows up for the handover and demands extra work be done. The landlord can also charge you, if the company refuses to continue cleaning after their initial job - since, at the handover, the flat has to be as clean as the landlord (and not you (the tenant) or the cleaning company) wants it to be.

Diamond cleaning have a good reputation. The provide the handover guarantee.

Thanks everyone very helpful. Especially about the arrangement to clean until landlord satisfied.

Diamond Cleaning recently cleaned my apartment. Would recommend them. No issues or problems at all.

would recommend ZuriClean. they are very professional and quick servcice.
