Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Your own checks

What to check before you hire

Worth checking yourself
Only a few public reviews are shown. Ask for recent references you can contact.
Agree the callout fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemized quote (parts and labor separately) before agreeing to major work.
Gas work is licensed separately from general plumbing in most states. Make sure anyone working on a gas appliance or gas line is licensed for gas work under your state's rules, and ask for proof of that license before they start.
