I live in Co Durham. I'm afraid that cleaning companies such as you are after are a completely unknown quantity to me but I would say that we (i.e people in the county) have, certainly until now, been highly compliant with mask wearing, which is one of the most essential anti covid measures, so you'll probably be OK with any local company.
As for getting to know people, speaking as an 'incomer' (albeit 30+ years ago) I found that Durham people are mostly the nicest, friendliest, most welcoming people you could wish to meet. I'm sure you'll be fine.
I love my adopted county
