Emergency and utility numbers in Texas
For gas odor, downed power lines, or flooding, call 911 or your utility emergency line first — not a contractor. After the immediate hazard is controlled, hire licensed pros for permanent repair.
- 911 — fire, medical, immediate life safety
- Gas odor — leave the building, do not switch lights, call your gas utility emergency number from outside
- Power outage / lines down — utility emergency line; stay away from downed conductors

Verify before you hire in Texas
Check the licence with the Texas board
Journeyman and master licenses are issued by states or municipalities; most require documented hours plus an exam. Search the number in the state's public lookup, confirm it is active, and confirm the classification covers your job rather than something adjacent to it.
Have the insurer send the certificate
Ask for general liability and workers' compensation to be sent to you directly by the insurance agent. A PDF forwarded by the contractor proves the document existed once, not that the policy is current.
Get the scope in writing, with exclusions
What is included matters less than what is excluded. Permits, disposal, patching, and code upgrades triggered by the work are the four line items that most often turn into change orders.
Confirm who pulls the permit
Permit thresholds are municipal in Texas. The licence holder should pull it. If you are asked to pull it as a homeowner on licensed work, you are absorbing their liability.
Never pay the full amount up front
A deposit for materials on a large job is normal. Paying in full before work begins is not, and several states cap what a contractor may take as a deposit.
Work out the problem before you call
- ElectricalBreaker Keeps TrippingUnderstand why a circuit breaker trips repeatedly and which causes are safe to investigate yourself.
- ElectricalOutlet Not WorkingA dead outlet or one that stopped working — check these causes before calling an electrician for a simple fix.
- ElectricalGFCI Won't ResetA GFCI outlet or breaker that will not stay reset — there is a ground fault somewhere on the circuit that must be found.
- ElectricalLights FlickeringLights that flicker or dim — determine whether it is a loose bulb, an overloaded circuit, or a problem at the panel.
- ElectricalBreaker Won't ResetA circuit breaker that trips and will not stay on — the circuit has a fault that must be found before you reset again.
- VentilationBathroom Fan Not VentingA bathroom exhaust fan that runs but does not move air — moisture stays in the room and mold follows within weeks.
- ElectricalHalf of Outlets Not WorkingWhen some outlets work and others do not, look for a tripped GFCI, tripped breaker, or a failed outlet feeding the chain.
- ElectricalBurning Smell From OutletA burning or fishy smell at an outlet means overheating — shut the circuit off until the device is replaced or inspected.
- ElectricalWarm Light SwitchA warm switch is drawing excessive current or has a bad connection — common with dimmers on heavy or incompatible loads.
- ElectricalBuzzing Breaker PanelBuzzing from the panel suggests a loose breaker, failing AFCI/GFCI, or arcing at lugs — treat as urgent.
- ElectricalLights Dim When Appliance RunsVoltage dip when a large load starts usually means shared circuit overload or a loose neutral.
- ElectricalBulbs Burning Out FastPremature bulb failure points to high voltage, vibration, poor contacts, or wrong dimmer.
- ElectricalFlickering Whole HouseWhole-house flicker suggests utility supply issues, loose main neutral, or large motor loads on the service.
- ElectricalSmoke Alarm ChirpingPeriodic chirps usually mean low battery, end of life, or dust — pattern matters on hardwired units.
- ElectricalOutdoor Outlet DeadDead exterior outlets are often a tripped GFCI indoors, moisture in the box, or a tripped breaker.
- ElectricalTwo-Prong OutletsUngrounded two-prong outlets limit safe grounding for modern electronics — understand options before upgrading.
- ElectricalElectrical Panel Is FullNo open breaker spaces blocks EV chargers, heat pumps, and subpanels — plan a tandem audit or upgrade.
- ElectricalGarage Outlet Keeps TrippingGarage GFCI trips from moisture, freezer faults, or garage door opener leakage.
- ElectricalPool Light Not WorkingPool lights combine water, electricity, and sealed niches — leaks and tripped GFCIs are common.
- ElectricalDoorbell Not WorkingSilent doorbells trace to button, transformer, chime, or smart doorbell wiring.
- ElectricalCeiling Fan WobblingFan wobble comes from blade balance, loose mounting, or a bent blade — fix before it loosens the box.
- ElectricalDimmer Switch BuzzingBuzzing dimmers often mean incompatible LEDs, overloaded dimmer, or loose wire.
- AppliancesDryer Not HeatingAn electric dryer that tumbles but stays cold usually means a tripped breaker, blown thermal fuse, or failed heating element.

- AppliancesOven Not HeatingOven not reaching temperature traces to breaker, igniter, bake element, or temperature sensor.
- AppliancesFridge Not CoolingWarm fridge with running compressor often means dirty coils, failed fan, or sealed system leak.
- AppliancesMicrowave Not HeatingMicrowave runs but does not heat usually means failed magnetron, diode, or door switch — rarely DIY.
