Licensed and insured.
This is a premium service, not an odd-job call. A trained professional arrives in a professional vehicle with the right tools, treats your home with care, and stays with you from the first call to the final walk-through. Every visit is licensed and insured, and every job carries a 12-month guarantee.
The usual way: a guy with a rusty truck, a different stranger each visit, and no insurance when something goes wrong.
