A Leak Is Costing You Money Right Now. Universe Finds It.

Leaks often develop behind walls, under floors, or beneath foundations, where they can quietly cause damage for weeks or months.
Professional leak detection from Universe Home Services helps identify the source early to limit structural damage and prevent mold growth. For homeowners across Long Island, early detection can mean the difference between a minor repair and a major renovation. With the right tools and experience, leaks can be located accurately without unnecessary demolition, saving time and reducing repair costs.

Signs You Need Leak Detection
Leaks can remain hidden for long periods. Recognizing early warning signs helps prevent extensive water damage.
A noticeable rise in your monthly water bill often indicates hidden water loss. If your daily habits have not changed, there may be a leak somewhere in your plumbing system. Even small leaks can waste significant amounts of water over time, and the bill is often the first place a leak actually announces itself.
Water stains on ceilings, walls, or flooring typically signal moisture behind surfaces. These areas may feel soft or slightly swollen to the touch. Acting quickly prevents further structural deterioration and costly restoration, and the stain itself is already evidence that the leak has been at work for longer than you realize.
Persistent musty smells can indicate trapped moisture inside walls or under flooring. Mold and mildew thrive in damp conditions, even when visible water is not present. Leak detection helps identify the moisture source before air quality becomes a concern.
Hearing water flow when all fixtures are turned off is often a red flag. This sound may point to a concealed leak behind walls or beneath flooring. Investigating quickly helps prevent long-term damage, and the sound itself is often the earliest warning a homeowner actually notices.

The Home Comfort Club and Leak Detection
The Home Comfort Club does not include leak detection under its whole-home plan.
The plumbing benefit in the Home Comfort Club is a basic visual inspection of accessible plumbing systems. It does not include acoustic, moisture, or pressure testing equipment required to locate hidden leaks.
Home Comfort Club members receive priority scheduling and a member discount on leak detection when it is needed, and a plumber who identifies leak symptoms during a visual inspection visit documents them and schedules the detection work as a separate service at member rates.

Why Long Island Homeowners Rely on Universe for Leak Detection
Universe Home Services began as a small, family-run company in 1954. Over time, we have grown into one of Long Island’s most trusted providers of plumbing, HVAC, and electrical services, serving communities throughout Nassau and Suffolk Counties.
When you call for leak detection, you are working with a team that understands regional homes, local infrastructure, and the common plumbing challenges found throughout Long Island.
Our plumbers are fully licensed and trained in advanced leak detection methods. Their experience ensures accuracy and safe workmanship, and the person locating your leak is qualified to recommend the honest next step once the source is identified.
Universe understands the pipe materials and layouts common in Nassau and Suffolk Counties. This familiarity allows for faster diagnosis and effective solutions, because a plumber who has already seen what fails in homes across Huntington, Hempstead, and Islip is not starting from zero on your specific situation.
Universe is a BBB Accredited Business that has been doing plumbing across Long Island since 1954. Decades inside these homes means the plumbers running leak detection calls have seen what typically leaks, where, and why across Farmingdale, Bethpage, Smithtown, and every town in between.
Universe focuses on practical solutions based on your specific situation. If a minor repair resolves the issue, more extensive work will not be suggested. The goal is a leak that is fixed, not a ticket that is padded.
Water damage can spread quickly. Our team responds promptly to limit further impact, which matters most when the leak is active and the homeowner is standing next to a growing wet spot.

Other Plumbing Services Universe Handles
Leak detection is the diagnostic. These are the other plumbing services Universe handles across Nassau and Suffolk County.
Once a leak is located, Universe handles the repair. Whether the source is a pinhole in a copper line, a failed joint, a corroded fitting, or a compromised fixture connection, the same licensed plumbers who found the leak are the ones who fix it.
Water heaters are a common source of hidden leaks, especially as the tank ages and minor seepage progresses toward tank failure. Universe handles water heater maintenance, repair, and replacement, which often becomes the follow-up work when leak detection points to the heater itself.
When leak detection surfaces a problem below slab or in the main sewer line, Universe inspects and addresses the line as a separate service. Camera inspection, sewer cleaning, and repair are all available through the same company, which means one call covers the full scope rather than coordinating across contractors.
A hidden leak sometimes ties to a drain condition that is contributing to the problem: a slow line backing up into a compromised joint, a fixture draining poorly because of upstream accumulation.
Universe handles scheduled drain cleaning as part of the broader plumbing scope.
An active leak that cannot wait for a scheduled appointment is an emergency, and Universe dispatches licensed master plumbers across Nassau and Suffolk County 24 hours a day. The same company that detects the leak is the one that stops it when the situation will not hold until morning.

Leak Detection Questions Answered
How is a hidden leak found?
Technicians use tools such as acoustic listening equipment, moisture meters, and pressure testing devices. These tools help isolate the leak’s location without opening large sections of walls or flooring. The goal is to identify the source accurately while minimizing disruption, which matters because exploratory demolition on a hidden leak gets expensive fast.
Can small leaks really cause serious damage?
Yes. Even minor leaks can gradually weaken building materials and create mold-friendly conditions. Over time, the damage can extend beyond the original leak location, which is why early detection is the point of the service.
How long does leak detection take?
Most inspections are completed within a few hours. Larger homes or complex plumbing systems may require additional time to test multiple areas thoroughly, and your plumber gives you a time estimate after the initial assessment so you know what to expect before the work starts.
Should I shut off my water if I suspect a leak?
If you notice active water flow or significant damage, turning off the main water supply can help prevent further harm. Once the water is off, contact a licensed plumber for professional evaluation rather than attempting to locate the source yourself.
