Sherlock Holmes Cleaning Services · Commercial Cleaning · Sandwich
Sherlock Holmes Cleaning Services handles the cleaning for Sandwich property managers who are tired of chasing certificates, invoices and no-shows. One contact, one invoice, paperwork without asking.
Consumables can be on us or on you. Either way it is decided at the start and not invoiced later as an extra line nobody agreed to.

Three things Sherlock Holmes Cleaning Services puts in writing before the first visit
The same crew each visit
Keyed, badged and background checked, and the same faces every week. Holiday and sickness cover is ours to arrange, not yours to notice.
Certificates on file
Insurance and liability documents go to you, your landlord or your property manager the day you ask for them.
A record of the work
You get a log of what was cleaned and when, which for a clinic or a food business matters as much as the cleaning itself.
