Resetting the water heater’s button may not fix the root problem; you likely need a professional inspection. Our licensed, background-checked technicians service electric, gas, and tankless units and will advise repair or replacement after an on-site evaluation. Call us 24/7 if you have no hot water. Watch for signs like leaks, rust-colored water, strange noises, low water pressure, or rising energy bills. We serve homes in Madison, Fitchburg, Sun Prairie, and nearby.

A water heater leaking from the bottom usually points to a failing tank or lower fitting and you should shut it down and call for service. Most often, internal corrosion causes the breach, and units around 10–15 years old are more likely to need replacement after inspection. We provide 24/7 help and will inspect the system to confirm if a repair is possible or if replacement is the safer, longer-term fix; we handle these calls across the greater Madison area, including the Deforest region.
If you can do so safely, take these steps:
- Turn off power: switch the electric breaker off, or set the gas control to off.
- Close the cold-water shutoff valve on top of the tank.
- Keep away from standing water near outlets or cords, and move valuables to reduce damage.
- Call for urgent service if leaking is active or worsening. A steady bottom leak usually means replacement is likely, so act quickly to limit water damage.

If your water heater isn’t producing hot water, schedule a diagnostic. Our licensed, background-checked plumbers handle electric and gas units and can advise repair vs replacement after inspection. We offer 24/7 emergency service in Madison and nearby cities. Common causes include a tripped breaker, failed heating element, extinguished pilot, bad thermostat, or a leaking tank.
Quick checks:
- Verify power at the breaker or switch.
- For gas, confirm the gas valve is open and pilot/igniter works.
- Press the unit’s reset button if present.
- Look for leaks or rust.

"Installed new heat pump system, water heater and duct cleaning. All work done professionally and quickly." — Chris G.
There isn’t a one‑price fits all. Replacement cost varies by unit type and installation needs. After an in‑home inspection, our licensed, background‑checked technicians provide a firm quote before work begins. Tank vs. tankless, capacity, fuel type (gas or electric), and installation complexity affect price. We handle full replacement and installation and can review financing options and a $25 off first‑time tankless service offer. Emergency service is available 24/7. We serve Madison, Fitchburg, and Sun Prairie.

You can, but we don’t recommend DIY water heater installation. Water heaters involve gas or 240 V electric connections, venting, and pressure relief that must be set up correctly to avoid leaks or damage. Our licensed, background-checked technicians inspect first and advise whether repair or replacement is best. We handle electric, gas, tank, and tankless units, and we offer 24/7 emergency support in Madison and nearby cities.
