Common questions
How do I vet a commercial cleaning contractor in San Diego?
Ask for four things in writing before you sign: a scope checklist tied to each visit, proof of who verifies the work in the field, photo or written documentation delivered with the invoice, and a current certificate of insurance naming you as additional insured. Then ask for a reference at a property the same size as yours.
