Hiring a plumber is a pain in the ass, especially when water is pouring through your ceiling. Most people panic, grab the first number they find, and pay triple. You don't have to be that person.
Before You Search
Figure out what you actually need. Is it a clogged drain or a slab leak? Are you replacing a water heater or getting a whole-house repipe? The more specific you can be, the harder it is for someone to upsell you on extras. Write down symptoms, not guesses. If you smell gas, get out and call the utility company first — that's not a plumbing job. Also check your own time. If you're calling at midnight on a Saturday, you're paying emergency rates, no way around it.
Vetting Candidates
Ask three people for a name: a neighbor, a realtor, and a hardware store employee. That's your shortlist. Google each one and read the bad reviews first. If the complaints are about pricing or slow response, that's normal. If they mention unlicensed work, shitty repairs, or damage to the house, cross them off. Call and ask if they carry liability insurance and workers comp. If they hesitate or say 'we're bonded,' that's not the same thing. Hang up.
Getting Quotes
Have at least three people come look at the job in person. Nobody reputable gives a firm price over the phone for something they can't see. Watch how they act. Do they measure things? Ask where pipes run? Look in the crawlspace? That's a sign they know what they're doing. If someone gives you a price in under five minutes, they're either guessing or padding the quote. Don't choose the cheapest or the most expensive. Pick the one who explains the problem and the fix in plain English.
Before You Sign
Read the scope of work. If it says 'repair leaking pipe' but doesn't say where, that's a blank check. Make sure there's a sentence about clean-up and protecting your floors. Ask how they handle discovering more damage once they open a wall. A good contractor will stop and call you before doing extra work. Never pay the full amount upfront. Half is standard. The other half when the job passes inspection or when you see water flow again. Get the warranty terms in writing — parts and labor, minimum one year.
