What to check before you hire
Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
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.
