Water Heater Leak & Failure Cleanup in Marietta, GA

Last updated: September 2026

Slow leaks vs. catastrophic failure

Water heater failures come in two very different forms — and the quieter one often does more damage.

Slow leaks start at corroded fittings, aging valves, or a weeping tank seam. They seep for weeks or months, rotting subfloors, swelling baseboards, and feeding hidden damage inside walls. Homeowners usually discover them through a musty smell, warped flooring, an unexplained damp spot — or a water bill that crept upward for no clear reason.

Catastrophic failure is the aging tank giving way all at once. Tens of gallons hit the floor in minutes and keep spreading — across the utility room, under adjacent flooring, down through ceilings to lower levels. If your water heater sits in a garage, attic, or upstairs closet, the damage path is even wider.

Either way, the critical fact is the same: water migrates far beyond what’s visible, and it starts damaging materials immediately.

Key takeaways

• Turn off the water supply to the heater and the power or gas to the unit, then call a restoration company.
• PuroClean of East Cobb responds in 60 minutes or less, 24/7, and every call is answered by a live person.
• Cleanup follows a fixed sequence: assess, stabilize, document, restore, using documented extraction and controlled dehumidification.
• Thermal imaging and moisture meters find water that has spread under flooring and behind walls.
• You get one project manager from start to finish, photo/video documentation on every job, and a final walkthrough.

What to do right now

Do:

• Shut off the cold-water supply valve above the heater — usually a lever or gate valve on the pipe feeding into the top of the unit.
• Make the unit safe — flip the dedicated breaker for electric heaters, or turn the gas control to pilot/off for gas — but only if you can do so safely and without standing in water.
• Call (770) 627-0900. A live person answers 24/7 and will talk you through the next steps while help is dispatched.
• Photograph the unit and all water damage before anything is moved — wide shots plus close-ups for your insurance record.
• Move valuables, documents, and electronics out of the water’s path if you can do so safely.

Don’t:

• Don’t try to repair a leaking tank yourself. A failing tank is done — patching it wastes the hours that matter for mitigating the water damage.
• Don’t ignore a small puddle. Small, chronic leaks cause the worst hidden damage because they go unnoticed the longest.
• Don’t crank up the heat to “dry things out.” Excess heat warps wood and buckles flooring; structural drying requires controlled dehumidification.
• Don’t tear out wet materials yourself. Disturbing them without containment spreads the damage and complicates your claim.

Finding the water you can’t see

This is where water heater jobs are won or lost. Water from a failed heater runs under flooring, wicks up drywall, seeps into wall cavities, and travels to lower levels — long after the visible puddle is gone.

We map the full extent with thermal imaging and moisture meters before writing the drying plan, so it’s built on readings, not guesses. Drying is then monitored against a documented dry standard with daily logs. When we say it’s dry, the numbers prove it — and your insurance carrier gets the same proof.

Our process: assess → stabilize → document → restore

Assess. Source, spread, and water category — mapped with thermal imaging and moisture readings across every affected room and level.

Stabilize. Standing water extracted, affected areas set up for controlled structural drying to industry standards.

Document. Moisture readings, drying logs, and photo/video documentation on every job — the file your adjuster needs to keep your claim moving. Our owner spent 16 years in the restoration and insurance industry, including time as a Property Claim Manager at a national carrier, and we teach CE classes for insurance agents. We build claim files that get approved.

Restore. One project manager owns your job from first assessment to final walkthrough — no handoffs mid-job. Damaged materials are repaired or replaced, and you walk the space together to confirm it’s back to pre-loss condition.

What water heater failure restoration costs — and what insurance covers

Per a Forbes Home report, the national average cost of water damage restoration is between $1,300 and $5,600. Where your job lands depends on how far the water traveled, how long a slow leak ran before discovery, and how much material must be dried versus replaced.

On insurance, the distinction that matters: damage from a sudden rupture is often covered as a sudden and accidental event, while damage from a long-term slow leak is commonly excluded. The aging unit itself is typically considered wear and tear — your adjuster makes the final call on all of it. Our role is documentation: drying logs, photos, video, and industry-standard line-item estimates. We price on the estimating platforms major carriers accept — no vague lump sums, no fine print.
