If You Smell Gas, Do This First
Gas work is the one plumbing trade where the wrong first move can be catastrophic. So before anything about repairs, pricing, or propane: if you smell rotten eggs, hear hissing near a gas line or meter, or your carbon monoxide alarm is sounding, treat it as an emergency right now.
⚠ Gas Leak Emergency Protocol
- Leave immediately. Get everyone — people and pets — out of the house. Do not stop to open windows, find the source, or grab belongings.
- Do not flip switches or use phones indoors. Do not turn lights on or off, do not use a landline or cell phone inside, do not light anything, and do not start a car in an attached garage. A spark is all it takes.
- Call 911 from a safe distance. Once you are well away from the house — across the street, not the driveway — call 911.
- Then call the gas company. For natural gas, call UniSource Energy Services (gas and electric), the utility that serves Lake Havasu City — their emergency number is on your gas bill. For propane, call your propane supplier’s emergency line as well.
- Do not go back inside until firefighters or the utility declare it safe. Then — and only then — call us to find the leak, repair it to code, pressure-test the line, and handle the permit and inspection.
Once the emergency is over, the repair work begins — and that is where a specialist matters. Gas piping follows its own code: lines must be sized to the total appliance load, joints and materials are strictly specified, and every new or modified line must hold a pressure test before gas is restored. It is the same precision-first mindset we bring to leak detection across the city: find the exact failure point with instruments, not guesses, then fix exactly that. And because so many gas lines here feed water heaters — including the exterior-mounted tankless units common in Lake Havasu City — our water heater repair team coordinates gas hookups, re-lights, and safety checks as part of the same visit.
We also handle drain cleaning, burst pipe repair, and the rest of the home’s plumbing — but gas gets its own protocols, its own technicians, and its own permits, every time.
Propane Country: Two Kinds of Gas in Lake Havasu City
Lake Havasu City is a two-gas town, and most plumbing websites pretend it is a one-gas town. Here is the real picture. The natural gas utility is UniSource Energy Services (gas and electric) — one company delivering both natural gas and electric service across Mohave County, with a local office at 2749 Maricopa Ave in Lake Havasu City. Not Southwest Gas. If a bill, a contractor, or a website tells you otherwise, check the name on your meter.
But a large share of homes here never touch that utility’s gas mains at all. They run on propane delivered by truck to an on-site tank — and the demand is proven, not theoretical: A&B Propane has served this market for more than 30 years with bottle delivery, bulk tanks, and installations, and local plumbers advertise propane tank installs as a core service. Homes on the fringes, in county pockets, on larger lots, and in many second-home and RV-oriented properties are propane homes. If you have a big tank on your property that a truck refills, that is your system.
The distinction matters because the two gases are regulated differently, sized differently, and serviced differently — and hiring a plumber who only understands one of them is how jobs go wrong. Here is the honest comparison:
| Natural Gas (UniSource) | Propane (delivered) | |
|---|---|---|
| How it arrives | Underground utility mains to a meter at your house; monthly bill | Delivery truck fills your on-site tank (above-ground or buried); you buy by the gallon |
| Who to call in an emergency | 911, then UniSource Energy Services (gas and electric) | 911, then your propane supplier’s emergency line |
| Pressure & sizing | Low-pressure utility delivery; lines sized to total appliance load | Higher-pressure tank system with its own regulators; lines sized differently — not interchangeable math |
| Appliances | Built or converted for natural gas | Require propane-rated orifices and conversion kits — a natural-gas appliance on propane is dangerous |
| Second-home factor | Service stays on; bill continues while you are away | Tank level must be monitored — run dry and every pilot and appliance needs a professional re-light and leak check |
| Common failure points | Aging yard lines, corroded fittings, added appliances overloading the original line size | Regulator wear, tank valve and pigtail deterioration in desert heat and UV, buried copper corrosion |
We service both systems — and we say so explicitly because almost nobody in this market does. Whether your home takes gas from UniSource Energy Services (gas and electric) or from a propane tank in the side yard, the work gets the same treatment: sized to load, pressure-tested, permitted, and inspected. If you are buying a home here and cannot tell which system it has, start with our Lake Havasu City plumbing hub — or just call (866) 471-4088 and we will walk you through the five-minute check.
Gas Line Services in Lake Havasu City
Every gas job we take — natural gas or propane — ends the same way: pressure-tested, permitted, and inspected. Here is the work itself.
Gas Leak Detection
Electronic detectors, pressure-decay testing, and isolation of line segments to pinpoint the exact leaking joint or section — not a guess, and not a whole-house repipe sold on a hunch. If you smell gas, see the emergency protocol above first.
Gas Line Repair
Corroded fittings, damaged yard lines, leaking valves, and failed joints repaired to current code with proper materials — then pressure-tested before gas is restored. The cheapest gas line repair Lake Havasu City homeowners never need is the one prevented by fixing small problems early.
Full Line Replacement
When a yard line is failing along its whole run — common in the city’s 1970s–1990s housing stock — we replace it at proper depth with correctly sized pipe, new shutoffs, and full permitting. Caliche excavation is priced as an explicit line item, never a surprise.
New Gas Lines for Appliances
Ranges and cooktops, dryers, gas water heaters, outdoor kitchens and grills, fire pits, patio heaters, and pool heaters — every new line is sized to the appliance’s load plus the existing load on the system, so adding a grill does not starve the water heater.
Propane System Service
Regulator replacement, pigtail and valve service, buried-line inspection, tank-to-house line repairs, and conversion checks when appliances change. We also set up propane tank monitoring guidance for absentee owners (more below).
Re-Lights & Safety Checks
After any gas work — or after a propane tank runs dry — every pilot and appliance gets a professional re-light with a leak check at each connection. We also perform annual gas safety inspections: shutoff locations, flex-connector condition, regulator dates, and carbon monoxide alarm placement.
Call 811: Caliche Hides Gas Lines
In Lake Havasu City, digging is hard — and that makes it dangerous. USDA soil surveys describe ground here with 35 to 70 percent coarse fragments and cemented caliche layers. Homeowners compensate with rented jackhammers, pickaxes, and powered augers. Powered digging through rocky ground is exactly how buried gas lines get struck: the operator is fighting the soil, focused on the rock, and the line gives way before the rock does.
Arizona law requires calling 811 before any digging project — planting a tree, setting fence posts, installing landscape lighting, trenching for irrigation. The call is free. Within a few business days, locators mark the approximate path of underground utilities with paint and flags, including gas. It does not mark your private lines (the yard line from the meter to your house, or propane lines on your property), which is why a professional locate of private lines matters before any excavation near them.
When we excavate for gas line work, we locate first — public utilities through 811 and private lines with our own equipment — and we hand-dig within the tolerance zone around any marked line, exactly as the rules require. If your project involves digging anywhere near a gas meter, a propane tank, or the path between them, call (866) 471-4088 before you pick up the shovel. A five-minute conversation beats a gas leak every time.
Permits & Pressure Tests: How a Gas Job Is Done Right
Gas is the one trade where “looks fine” is not a test result. Here is the process every one of our gas jobs follows — ask any competitor to describe theirs before you hire them.
Load calculation and sizing
Every appliance on the line is totaled by BTU load, and the pipe is sized for the full load over the full run length. An undersized line starves appliances — the classic symptom is a water heater that underperforms every time the furnace or grill runs. We size on paper before we cut pipe.
Permit pulled
Gas line repair and replacement in Lake Havasu City and Mohave County typically requires a permit. We pull it, post it, and schedule the inspection. Skipping the permit can void your homeowner’s insurance coverage for the work and create disclosure problems when you sell — in a market with heavy second-home turnover, that matters.
Installation to code
Proper materials for the application (never the wrong pipe for the job), protected penetrations, accessible shutoffs at each appliance, sediment traps where required, and correct burial depth with warning tape on underground runs. Caliche excavation is done with rock-capable equipment and priced as a line item.
Pressure test
The new or repaired line is isolated and held at test pressure while we watch for decay — the test that proves the system is tight, not just assembled. No test, no gas. This is the step skipped by every shortcut artist in the trade.
Inspection and re-light
The inspector signs off, gas is restored, and every appliance is re-lit with a leak check at each connection. You get the permit record and the test result in writing — documentation that protects you at resale and with your insurer.
What Gas Line Repair Costs in Lake Havasu City
No reputable company prices gas work sight unseen — the variables (length, depth, soil, access, permit fees) are too big. With that understood, here is what Lake Havasu City homeowners commonly see, so you can recognize an outlier quote:
| Service | Typical range | What drives it |
|---|---|---|
| Diagnostic visit + leak detection | $200 – $450 | Testing time, line isolation, access |
| Minor repair (valve, fitting, short section) | $250 – $800 | Location, material, accessibility |
| New appliance gas line | $500 – $1,500 | Distance from manifold, load sizing, wall/floor work |
| Yard / service line replacement | $1,500 – $5,000+ | Trench length, depth, caliche, surface restoration |
| Propane regulator / pigtail service | $200 – $600 | Regulator type, tank access, re-light scope |
Ranges reflect what homeowners in this market commonly encounter. Your written quote follows an on-site inspection and load calculation — you approve the fixed price before work begins, and permit and inspection fees are passed through at cost.
Gas-Piping Certification: What to Ask Before You Hire
Here is something the industry does not advertise: not every plumber is qualified to touch gas. Gas piping is a specialty within the trade. It requires its own training in load calculations, materials, joining methods, pressure testing, and the fuel-gas code — and in Arizona, the contractor’s ROC license classification has to cover the work being performed. A handyman with a wrench and a YouTube education is not a gas fitter, no matter how confidently he holds the pipe dope.
Before you hire anyone for gas work in Lake Havasu City — us included — ask these four questions and require written answers:
1. What is your ROC license number?
Then verify it yourself at roc.az.gov — check that the license is active and the classification covers gas piping. This takes two minutes and eliminates most of the bad actors in the market. Anyone who hesitates to give you the number has told you everything.
2. Who exactly does gas piping on your crew?
Ask whether the technicians are specifically trained in gas piping — not just “our guys do it all.” Gas sizing, pressure testing, and CSST bonding are specialty skills. The person doing your gas work should be able to explain a load calculation without reaching for a manual.
3. Will you pull a permit and pressure-test?
The answer must be yes to both, in writing, before work starts. “We can skip the permit to save you money” is a contractor telling you to trade your insurance coverage and resale disclosure for his convenience. Walk away.
4. What is the fixed price, in writing?
Gas work priced “by the hour, we’ll see” is how a $600 repair becomes a $2,400 invoice. Demand a fixed written price tied to a defined scope — including the caliche excavation allowance if trenching is involved — before anyone picks up a tool.
Ask us the same four questions. We will answer every one in writing, give you the ROC number to check at roc.az.gov, and show up with the permit application already understood. That is what a gas specialist looks like — and in a two-gas town like Lake Havasu City, where half the homes run propane and the other half run UniSource natural gas, the specialist is the only safe hire.
Second Homes & Propane: The Tank Nobody Is Watching
Lake Havasu City has one of the highest seasonal-home shares in Arizona — roughly three-quarters of vacant housing units are designated for seasonal use. Many of those second homes run on propane. Combine an absentee owner, a propane tank, and months of desert heat, and you get the failure mode nobody talks about: the tank nobody is watching.
Here is what goes wrong. Propane does not send you a bill when it runs low — it just runs out. A tank that empties while the house sits vacant means every pilot light and gas appliance shuts down, and refilling is not a do-it-yourself restart: every appliance needs a professional re-light with a leak check before the system is safe again. Worse, regulators, pigtails, and valves age in place under some of the harshest UV and heat in the country — the city holds Arizona’s all-time heat record at 128°F — and a slow leak at a regulator can vent propane for weeks with nobody home to smell the additive.
For natural-gas second homes on UniSource Energy Services (gas and electric), the risk profile is different but the discipline is the same: an arrival inspection that checks flex connectors, shutoff function, and appliance operation before the house goes back into full use. A home that sat quiet for five months deserves thirty minutes of professional attention before the grill, the water heater, and the fire pit all fire up on the same weekend. Bundle it with a water heater check and a drain flush, and the season starts without surprises.
Three Representative Gas Jobs in Lake Havasu City
The following are representative scenarios based on common local conditions, not accounts of specific customers.
The Snowbird Propane Return
A couple arrives at their 86403 second home in October to find the propane tank at four percent — and a faint gas smell near the regulator. They do the right thing: leave the area around the tank, call from a distance, and wait. Our tech finds a regulator whose diaphragm has failed after years of desert heat and UV, venting propane at the vent port. We replace the regulator and pigtails, pressure-test the house line, re-light every appliance with a leak check at each connection, and set them up with a cellular tank monitor so the phone — not an empty tank — tells them next time.
The Desert Hills Outdoor Kitchen
A homeowner in 86404 wants a gas line run 60 feet to a new outdoor kitchen with a grill and fire pit. The load calculation shows the existing house line cannot carry the added BTU load — the classic undersizing mistake. We run a dedicated, properly sized line from the meter, trenched through caliche with rock-capable equipment (excavation priced as an explicit line item), permitted and pressure-tested. An 811 locate beforehand reveals the old yard line crossing the planned trench path — we hand-dig that section. The grill lights, the water heater never notices, and the inspector signs off the same week.
The Riviera Pool Heater Conversion
A 86406 home with a propane pool heater is burning through expensive propane gallons heating a pool the owners use half the year. The house already has UniSource natural gas at the meter — but the heater is propane-rated. We handle the full conversion: verify the heater’s natural-gas conversion kit, run a new dedicated gas line sized for the heater’s load plus existing appliances, pull the permit, pressure-test, coordinate the meter capacity check with UniSource Energy Services (gas and electric), and commission the heater on natural gas. The owners keep the propane tank for the fire pit — two gases, each on the right system.

Gas Line Repair FAQs
The questions Lake Havasu City homeowners actually ask us about gas — answered straight.
What should I do if I smell gas in my Lake Havasu City home?
Leave the house immediately with everyone in it. Do not flip light switches, use a phone indoors, light anything, or start a car in the garage. From a safe distance, call 911. Then call your gas provider: UniSource Energy Services (gas and electric) for natural gas, or your propane supplier’s emergency line for propane. Do not re-enter until emergency responders say it is safe. After the all-clear, we locate the leak, repair it to code, pressure-test the line, and handle the permit and inspection.
Who provides natural gas in Lake Havasu City – UniSource or Southwest Gas?
UniSource Energy Services (gas and electric) is the natural gas utility for Lake Havasu City, with a local office on Maricopa Ave. Southwest Gas does not serve Lake Havasu City. UniSource is a dual utility here: the same company delivers your natural gas and your electricity. If a contractor or website tells you otherwise, check the name on your meter and your bill.
How can I tell whether my home uses natural gas or propane?
Look for a gas meter on the outside of the house and a monthly gas bill from UniSource Energy Services: that is natural gas. If instead you have a large tank on your property that a delivery truck refills, that is propane. The distinction matters because line sizing, regulators, appliance conversions, and emergency contacts are all different. When in doubt, check your utility bills or call us and we will walk you through the check.
What does gas line repair cost in Lake Havasu City?
No reputable company prices gas work sight unseen. As a planning guide, diagnostic visits with leak detection run $200 to $450, minor repairs such as a valve or fitting run $250 to $800, new appliance gas lines run $500 to $1,500, and full yard or service line replacements run $1,500 to $5,000 or more depending on trench length, depth, and caliche excavation. Permit and inspection fees are passed through at cost, and you approve a fixed written price before work begins.
Do I need a permit to repair a gas line in Lake Havasu City?
In most cases, yes. Gas line repair and replacement in Lake Havasu City and Mohave County typically requires a permit, and the work must pass a pressure test and an inspection before gas service is restored. Skipping the permit can void your homeowner’s insurance coverage for the work and create disclosure problems when you sell. We pull the permit, schedule the inspection, and document the pressure test in writing.
Do I really need to call 811 before digging in my own yard?
Yes. Arizona law requires calling 811 before any digging project, including fence posts, trees, and irrigation trenches. The call is free, and locators mark public utility lines within a few business days. In Lake Havasu City’s caliche soil, where powered digging is the norm, striking a buried gas line is a realistic risk: the rock fights back and the line loses. 811 does not mark your private lines, so have those located professionally too before excavating near a meter or propane tank.
Is propane safe for a second home that sits empty for months?
Propane is safe when the system is sound and monitored, but an unwatched tank is the risk: tanks can run dry (requiring a professional re-light of every appliance) and regulators age in desert heat and UV. We recommend a cellular tank-level monitor that alerts your phone, a gas safety inspection before each season’s arrival, and a trusted local contact with access. If you arrive to a dead tank or a gas smell, do not re-light anything yourself: call us for a proper re-light with leak checks.
Can any plumber work on gas lines, or do I need a specialist?
You need a specialist. Gas piping requires its own training: load-based pipe sizing, code-specific materials and joining methods, pressure testing, and permit handling. Before hiring anyone, ask for their ROC license number and verify it at roc.az.gov, ask who on the crew is specifically trained in gas piping, and require a written commitment to pull a permit and pressure-test the work. Ask us the same questions: we answer all of them in writing before we start.
