Open →Start here if water is leaking now
If water is actively leaking, the most useful first step is usually to shut off your main water if you can do so safely. Our guide at how to shut off your water walks through the basics in plain words.
If you smell gas, or water is near live electrical equipment, leave the area and call your local emergency number first. MainLine Match gives general information only and is a free matching service — not a plumbing company, licensed plumber, or contractor.
What these guides cover
We built these guides for people who need fast, clear help — especially if English is not your first language or this is your first home emergency in the US. They explain common situations like a burst pipe, no hot water, a sewage backup, a bad clog, no water, or a major leak.
You can use them to understand what to do first, what questions to ask, what emergency plumbing may cost, and how to avoid being pressured into a repair you do not understand.
Honest cost help, not scary promises
Our cost guides give general price ranges so you have a rough idea before you call. These ranges are not quotes. The real number depends on the problem, the time of day, the parts needed, how hard the job is, and where you live in the US.
After-hours visits usually cost more. A simple clog may cost much less than a broken sewer line or a leak inside a wall. Local rules and who is responsible for a line or repair can also vary by area.
How MainLine Match helps
MainLine Match is free for the household. We do not do plumbing work. We help connect people with licensed, insured, 24/7 emergency plumbers near them based on the problem, ZIP code, and preferred language.
If you want help now, you can get matched or visit help. We only collect basic contact and problem details: your name, phone, optional email, problem type, ZIP code, and preferred language.
How to avoid overpaying in an emergency
In a real plumbing emergency, it is easy to feel rushed. Try to slow the decision down just enough to ask for the price in writing before work starts. You stay in control: you confirm the price first, choose who to hire, and confirm the work is done before paying the final amount.
Be careful if someone uses scare tactics, gives only vague pricing, asks for cash only, will not show license or insurance information, or pressures you to approve a very large repair immediately. When possible, ask what is urgent right now and what can wait.
These guides help you act fast, understand likely costs, and avoid pressure while finding a licensed, insured plumber through a free matching service.
