ROC is the Arizona Registrar of Contractors, the state agency that licenses contractors and publishes a free search of every license it has issued. A license there means the contractor met the state's experience and bonding requirements and can be held to them. Ask the plumber who calls you for their ROC number and look it up yourself on the Registrar's public license search. It takes about a minute and it is the only check that does not depend on trusting us.
Mesa, Arizona, spans about eighty years of construction in one city. Lehi and the blocks around west Main Street go back to the 1940s and 1950s and still run cast iron drains and galvanized supply. East Mesa, Superstition Springs, and Eastmark are 1990s and newer, on slab with PEX or copper. Mesa is also one of the few cities in the country that runs its own natural gas utility, so a gas emergency here goes to City of Mesa Energy Resources rather than Southwest Gas. Knowing which Mesa you live in changes what fails and who you call first. If it is happening right now, call (480) 000-0002 and a dispatcher will get a licensed plumber moving.
What to do right now
- Shut off the main water valve. In most homes it is at the street meter box or on the wall where the supply line enters.
- Open the lowest faucet in the house to drain pressure out of the lines.
- If water is near outlets, a panel, or a furnace, kill power to that circuit at the breaker.
- Move anything you care about off the floor and take photos before you clean up. Your insurer will ask.
- If you smell gas, do not touch a switch. Leave the house, then call from outside.
What we get called about in Mesa, AZ
Burst pipe
Which Mesa you are in decides how this goes. In Lehi and the older west Mesa blocks the supply is often galvanized steel that has been rusting from the inside since Eisenhower, and it lets go at a threaded joint inside a wall. In east Mesa and Eastmark it is copper or PEX and the failure is usually a fitting or a line that froze in an uninsulated exterior wall during a cold snap. Either way, shut the main off first, usually at the meter box by the sidewalk, then open the lowest faucet in the house to drain the pressure. Do not run the water heater dry. If you shut the main, kill the heater at the breaker or set the gas valve to pilot.

No hot water or leaking water heater
A Mesa water heater fights hard water every day of its life. Scale builds on the tank bottom, the burner has to work through it, and the steel cooks. Popping and rumbling means sediment. Rusty hot water means the tank is corroding and the anode rod was consumed years ago. If water is coming from the body of the tank, it is done and no repair will save it. Close the cold inlet valve on top, cut power at the breaker for an electric unit or turn the gas control to off, and call. If the drip is coming from the temperature and pressure valve or a union fitting, that is a part swap and you will have hot water tonight.
Sewer backup
Cast iron main lines under west Mesa and Lehi are the single most common cause of a whole house backup in this city. Seventy years of scale narrows the pipe until one bad week of grease or wipes closes it. Roots find the joints of clay laterals in the same neighborhoods. The signal is always the same: flush a toilet and the shower fills, or run the washer and the floor drain comes up. Stop using water in the house immediately, then call. A cable will open it tonight. A camera afterwards tells you whether you have a blockage or a collapsed line, and in older Mesa it is worth knowing which.

Toilet overflowing
Push the flapper closed by hand to stop the tank refilling, then shut the angle stop valve on the wall behind the toilet. On original 1960s and 1970s Mesa hardware those valves seize, so if it will not turn, go to the meter box at the street. After the water stops, check the rest of the house. If other drains are gurgling or slow at the same time, the toilet is only the lowest point of a main line blockage and clearing the bowl will not fix anything. If everything else runs clear, it is a local clog or a failed flapper and it is a fast visit.
Smell of gas near a water heater
Leave the building first. Do not touch a light switch, a garage door opener, or anything else electrical on the way out. Do not go back in to check the pilot.
Mesa is unusual: the city owns and operates the natural gas system through City of Mesa Energy Resources, so a gas leak in most of Mesa is reported to the city, not to Southwest Gas. If you smell rotten eggs near a water heater, furnace, or range, do not touch a light switch or a garage door opener. Get everyone out of the house and call the city gas emergency line and 911 from outside. The utility makes the line safe. After that, a plumber replaces whatever failed: a cracked flex connector, a corroded sediment trap, or a gas control valve on the heater. If you are on the Apache Junction or Gilbert edge of the city, confirm which utility serves your address before an emergency.
Then call City of Mesa Energy Resources on (480) 644-4277, or 911, from outside. Mesa runs its own natural gas utility, so this does not go to Southwest Gas. Not us. We route plumbing and repair calls and we are the wrong first call for a live gas leak.
What emergency plumbing costs in the Phoenix metro
Prices surveyed 2026-09-12
These are market ranges taken from what local contractors publish, not quotes and not our prices. We set no prices and take no cut of the repair. Reaching the pipe is usually what costs, not the pipe.
| Job | Typical range | What drives it |
|---|---|---|
| Emergency or after-hours diagnostic call | $50 to $150 | Often credited against the repair. Ask whether it is, and get the number before a truck rolls. |
| Drain cleaning, one fixture | $150 to $350 | A branch blockage close to the fixture. Rises sharply if the main line is involved. |
| Main line cabling | $250 to $600 | Clears the symptom. Ask for a camera inspection before paying for it twice. |
| Water heater replacement | $1,200 to $2,500 | Tank units. An element or a thermostat is a fraction of this, so ask which failed. |
| Burst pipe or slab leak, spot repair | $500 to $2,000 | Access drives the number. The same break in a wall or under a slab costs multiples of one in an attic. |
| Whole home repipe | $4,000 to $12,000 | Quoted when spot repairs stop being economic on failing galvanized or polybutylene. |
Ask for the diagnostic fee, whether it is credited against the repair, and whether drying and reinstatement are included. Most plumbers fix the pipe and leave the wall open.
Bars are on a logarithmic scale from $50 to $12,000, so the smallest and the largest job on this table are both readable on the same row.

Common questions
How fast can a plumber get to Mesa?
Dispatch runs 24 hours. Mesa is large and coverage is not uniform: crews reach the Fiesta District and Dobson Ranch faster than Las Sendas or Eastmark at 2am. Ask for a real ETA when you call and say which part of the city you are in.
Who do I call for a gas leak in Mesa?
City of Mesa Energy Resources runs the gas system for most of the city, so the emergency gas number is the city, not Southwest Gas. Call from outside the house, along with 911. A plumber handles the appliance side after the utility clears the line.
What does an emergency plumber cost in Mesa?
There is normally an after-hours dispatch or diagnostic fee on top of the repair, higher at night, on weekends, and on holidays. Ask for that figure on the phone before anyone is dispatched.
My house is from the 1950s. Do I need to replace the sewer line?
Not automatically, but you should know its condition. Cast iron and clay lines in Lehi and west Mesa are at the end of their design life. A camera inspection after a backup tells you whether you bought another ten years or whether the line is cracked and needs lining or replacement.
Where is the water shutoff on a Mesa house?
Usually in the city meter box at the front sidewalk, under a lid, needing a meter key. Many homes also have a shutoff on the exterior wall near the front hose bib. Find yours in daylight rather than at midnight in six inches of water.
Do I need a permit for an emergency repair?
Straight repairs and like for like water heater swaps in Mesa are handled by the contractor, who pulls what the city requires. Any licensed Arizona ROC plumber doing the work will know the local requirement. Be suspicious of anyone who says permits never apply.
Can you handle a mobile or manufactured home?
Yes, and there are a lot of them in Mesa. Say so when you call. The supply and drain layout under a manufactured home is different from a slab house and the tech will bring different parts.
Which ZIP codes do you cover in Mesa?
85201 through 85215, which is the whole city from Lehi and west Main Street across to Eastmark. Give your ZIP and your cross streets when you call: Mesa spans eighty years of construction and which end you are in changes what fails.
Does my plumber need an Arizona license for this?
For anything at $1,000 or more, or anything needing a permit at any price, yes. Arizona's handyman exemption applies only below $1,000 including labor and materials, only to casual or minor work, and never to anyone advertising as a licensed contractor. Ask for the ROC number and check it at roc.az.gov. Every contractor we work with is verified there before they take a call.
