Leak Detection & Repair in Portland, ME

Water & Gas Leak Services for Portland, ME Homes & Businesses

Not every leak leaves an obvious trail. Hidden leaks behind walls, under floors, underground, or within gas lines can go unnoticed for months, especially in older Portland, ME homes where aging pipe materials and Maine’s freeze-thaw cycles quietly stress the system. FONTUS provides professional water and gas leak detection and repair across Portland and southern Maine, locating the source, explaining what we find, and recommending the right fix.

Call FONTUS today at (207) 865-8165 to schedule leak detection and repair service in Portland, ME.

Our Leak Detection Services

Water Leak Detection: Hidden plumbing leaks can waste thousands of gallons and lead to mold and structural damage. We locate leaks in pipes, fixtures, and supply lines before they become larger problems.
Gas Leak Detection: Natural gas leaks require immediate attention. If you suspect a gas leak, our team can help identify the source and recommend the appropriate repair to restore safety in your home or business.

Common Signs of a Hidden Leak

Higher water bills, damp drywall, musty odors, reduced water pressure, or the smell of gas can all point to a problem that needs prompt professional attention. Watch for:

Unexplained increases in your water bill
Damp walls, ceilings, or floors
Water stains or discoloration
Mold or mildew growth
Musty odors
Reduced water pressure
The sound of running water when fixtures are off
Wet spots in your yard
Standing water near plumbing equipment
The smell of natural gas or sulfur
Hissing sounds near gas lines

How We Find & Fix Leaks

We don’t start by opening walls. Our process begins with a systematic diagnostic assessment that narrows the likely source before any access is needed, keeping disruption to a minimum and getting you answers faster.

Specialized Detection Tools:
We use acoustic listening devices, thermal imaging, and electronic detection equipment to pinpoint leaks without exploratory demolition. These tools let us determine whether a problem is in a supply line, under a slab, or inside a wall before we ever pick up a saw.

Whole-System Assessment:
Our evaluation covers supply lines, fixtures, water heaters, well components, pressure tanks, and water treatment equipment, not just standard plumbing runs. Because FONTUS handles the full water system, we can follow a leak wherever it originates rather than stopping at the edge of a typical standard plumber’s scope.

Clear Findings & Repair Recommendation:
Once we locate the source, we explain what we found in plain language and walk you through the most effective repair option. After the repair is complete, we perform pressure testing or system checks to confirm the leak is resolved before we close the job.

If You Smell Gas

Treat a suspected gas leak as a life-safety emergency. Leave the building immediately, avoid turning lights or appliances on or off, and call 911 or your natural gas utility’s emergency line from a safe location outside before contacting a plumber.

Why Portland Homeowners Choose FONTUS

Leaks can start anywhere in a water system: supply lines, fixtures, water heaters, wells, pressure tanks, and treatment equipment. FONTUS covers all of it. Because our services span plumbing, water treatment, wells, pumps, and water heaters, we can trace a leak into components that a standard plumber might not investigate. In an older Portland home, that whole-system view helps identify the source others may overlook.

Our founder, Thomas Marcisso, is a licensed Merchant Marine engineer who spent years managing pressurized water systems on oil platforms and commercial vessels, including serving as Chief Engineer on the F/V Wizard from Deadliest Catch. That engineering background shapes how we approach every diagnosis: methodical, thorough, and honest about what we find.

Accurate diagnosis before any repair
Honest recommendations once the leak is located
Complete water-system coverage across plumbing, wells, and treatment equipment
Safety as the highest priority on every job

Protect Your Home with Early Leak Detection

Many costly repairs begin with a slow, unnoticed leak. Early detection helps protect against water damage, mold growth, structural issues, wasted water, and rising utility costs. Catching a hidden leak before it spreads can keep a small problem from becoming a structural or health concern.

Frequently Asked Questions

How do you find a leak without tearing up my walls?

We use acoustic listening devices, thermal imaging, and electronic detection equipment to narrow the location before any access is needed, keeping disruption to a minimum.

My water bill jumped but I don’t see a leak. What should I do?

An unexplained spike in your water bill is one of the most common signs of a hidden leak. We investigate supply lines, fixtures, and all connected equipment to locate the source.

Do you handle both water and gas leaks?

Yes. We detect hidden water leaks and help locate and address gas line leaks, with safety as the first priority.

What happens if the leak turns out to be in my well or water treatment equipment?

Because FONTUS handles well systems, pressure tanks, and water treatment equipment directly, we can diagnose and address a leak in those components in the same visit rather than referring you elsewhere. That’s one of the advantages of our whole-system approach.

Monitoring for Leaks Between Professional Visits

A few simple habits can help you catch a developing problem before it becomes a costly repair. Here’s what Portland homeowners can do between professional inspections:

Check your water meter with all fixtures off. If the dial or digital display continues moving, water is flowing somewhere it shouldn’t be. That’s a reliable early signal of a hidden leak.
Track your monthly water bill. An unexplained increase month over month is often the first sign of a slow leak. If nothing in your usage has changed, the bill shouldn’t climb.
Inspect visible pipes regularly. Look under sinks, in basements, and near your water heater for signs of corrosion, mineral staining, or moisture. Catching surface deterioration early can reduce the chance of a failure inside the wall.
Maintain indoor heat through Maine winters. Keeping your home adequately heated reduces frozen-pipe risk. A pipe that freezes and cracks may not show a leak until it thaws, by which point damage can already be spreading inside the structure.
Respond to in-home leak sensor alerts promptly. If a sensor near a water heater, washing machine, or under a sink triggers, call a professional before attempting to investigate behind walls or panels yourself.
