Our plumbers have the skills and equipment needed to find the precise location of your water leak so that we can take steps to repair it.

Plumbing Pipe Leaks

When a plumbing pipe corrodes, cracks, bursts, breaks, or develops a pinhole leak, you’ll want to have it repaired immediately. Obviously, some pipe leaks do more damage faster than others, but any water leak will cost you money on your water bill, could cause water damages to your property, and has the potential to get worse over time.

A simple call to Thornton Plumbing, HVAC & Electrical is the only thing you need to do; we’ll take care of the rest. After our plumbers find your water leak, we’ll get you the pipe repair or repiping service that is needed to eliminate the leak.

Slab Leaks

When a plumbing pipe inside or under your home’s foundation springs a leak, this is called a slab leak. There are a variety of causes of slab leaks, but many times they occur because of a natural shift within the ground or because a pipe has corroded over time. These can be some of the most damaging of water leaks because if they go unfixed for long they can wash the soil around your home’s foundation away, causing an extra burden on the structure of your home. The longer a slab leak goes unrepaired, the more costly the resulting damages will be. It is absolutely imperative that slab leaks be detected and rectified as soon as possible.

Main Water Line & Sewer Line Leaks

While some plumbing companies will make a complete mess on your property while repairing or replacing main water lines or sewer lines, our plumbers have specialized equipment to tackle these plumbing projects. Our horizontal directional drilling service allows us to repair these tough leaks in less time and with less mess.

Signs of hidden leaks can include unexplained damp spots, cracks in your foundation, and the sound of running water when all fixtures are turned off. If you notice any of these indicators, it’s crucial to call a professional plumber right away. Our team at Thornton Plumbing, HVAC & Electrical will perform a thorough inspection to identify the source of the leak and provide a comprehensive repair solution.

Don’t Wait to Fix Water Leaks!

Water leaks in your plumbing system are a serious issue that requires immediate attention from a professional plumber. Ignoring leaks, even minor ones, can lead to significant damage and costly repairs down the line. At Thornton Plumbing, HVAC & Electrical, we emphasize the importance of addressing water leaks as soon as they are detected to avoid further complications.

One of the most compelling reasons to fix water leaks promptly is the conservation of water and the associated cost savings. A small leak can waste thousands of gallons of water over time, driving up your water bill and wasting a precious resource. Additionally, the energy used to filter and treat the water that is then wasted can be substantial, adding to your environmental footprint.

Another critical concern with untreated water leaks is the potential for mildew and mold growth. Mildew thrives in damp environments, and a hidden leak can create the perfect conditions for it to flourish. This not only poses a health risk to you and your family but can also lead to extensive and costly damage to your home’s structure.

Water leaks can also cause significant damage to your flooring and walls. Water naturally gravitates to the lowest point, which means it often ends up trapped under floorboards, tiles, or slabs. Over time, this can lead to cracks in your foundation, weakened structures, and even collapse. Similarly, leaks behind walls can cause drywall to weaken and deteriorate, compromising the integrity of your home.

At Thornton Plumbing, HVAC & Electrical, we offer comprehensive leak detection and repair services to address these issues promptly. Our licensed plumbers are trained to identify the source of leaks, even in the most hidden areas, and provide effective solutions to fix them. We also offer emergency services for those situations where immediate attention is required to prevent extensive damage.

Don’t let a small leak turn into a major problem. If you notice any signs of a potential leak, such as unexplained damp spots, cracks in your foundation, or the sound of running water when all fixtures are off, contact Thornton Plumbing, HVAC & Electrical immediately today at 317-697-9265. Our team is ready to provide the expert service you need to protect your home and keep your plumbing system in top condition. Serving Noblesville, IN, and the surrounding areas, Thornton Plumbing, HVAC & Electrical is your trusted partner for all your plumbing needs.

Frequently Asked Questions

Thornton Plumbing, HVAC & Electrical provides professional leak detection for water pipe leaks, slab leaks, gas leaks, main water line and sewer line leaks, and water leaks inside walls, floors, and foundations. Advanced non-invasive technology including acoustic listening devices, infrared cameras, and pressure testing equipment is used to locate leaks precisely before opening walls or floors.
A rising water bill without a visible source is one of the most common indicators of a hidden leak inside a wall, under a floor, or in the supply line outside the home. A professional leak detection visit uses specialized equipment to find the source without unnecessary demolition. Call Thornton Plumbing, HVAC & Electrical to schedule a leak assessment.
The sound of water moving through pipes when all fixtures are shut off is a strong indicator of a leak somewhere in the system. Turn off all appliances that use water and listen again. If the sound continues, a leak is likely. Check the water meter to see if it is still recording flow when everything is off. If it is, water is escaping and a plumber should assess the system.
Thornton Plumbing, HVAC & Electrical uses acoustic listening devices that detect the sound of water escaping under pressure through walls, floors, and soil; infrared cameras that identify temperature differences caused by moisture; and pressure testing equipment that measures pressure loss in sections of the plumbing system to confirm whether a leak is present and approximately where it is located.
Yes. Non-invasive leak detection uses acoustic and thermal technology to pinpoint leaks without opening walls or floors first. Once the location is confirmed, only a targeted opening at the leak point is needed for the repair, rather than large demolition to search for the source.
Signs include an unexplained increase in the water bill, the sound of running water when all fixtures are off, damp or wet spots on walls, ceilings, or floors, cracks appearing in flooring or walls, musty or mildew odors, warm spots on the floor that could indicate a hot water line leak, moisture in the crawl space or basement, and wet areas in the yard without rain or irrigation.
Yes. A slow hidden leak that runs continuously keeps the surrounding material wet and creates the moisture conditions that support mold growth within 24 to 48 hours. A leak inside a wall that is not detected for weeks or months can result in significant mold that requires remediation work beyond the plumbing repair itself.
Yes. Damp carpet without an obvious water source can result from a pipe leak inside the wall or subfloor below the carpet, a slab leak that is allowing water to wick up through the concrete, or condensation from a cold water line in a humid space. Leak detection can identify which of these is responsible.
A slab leak is specifically a leak in a pipe that runs beneath the concrete foundation of the home. The concrete slab sits above the leaking pipe, so the water cannot drain away and instead saturates the soil below and can eventually surface through the slab or cause foundation movement. A regular pipe leak inside a wall or ceiling does not involve the foundation.
Yes. A warm area on the floor, especially one that does not correspond to a heating vent or radiant heat system, can indicate a hot water supply line leak beneath the floor or slab. Hot water leaking from a supply line heats the surrounding area, which can be detected through the floor surface. Thermal imaging confirms whether a hot water leak is the source.
Not always. Small or slow leaks may not produce audible noise, especially when the sound is muffled by walls, insulation, or concrete. A rising water bill or unexplained moisture may be the only initial indication. Professional acoustic equipment is significantly more sensitive than the human ear and can detect leaks that are not audible without it.
A slowly flushing toilet can be caused by a partial drain blockage. A meter that continues to record flow when everything is off indicates a supply-side leak. These are likely two separate issues. The meter behavior warrants a leak detection visit to identify where water is escaping from the supply system.
Yes. A sustained slab leak erodes the soil beneath the concrete over time, which can cause the slab to settle unevenly and develop cracks. Cracks in a concrete slab floor that appear without an obvious cause and are accompanied by other leak symptoms should prompt a slab leak assessment.
After locating the leak, the technician presents the repair options based on the location, the pipe type, and the extent of the damage. Repair methods include direct access repair at the specific leak point, pipe section replacement, epoxy lining for certain pipe conditions, or pipe rerouting when direct access is impractical. See the slab leak page for slab-specific repair options.
Yes. Sustained water intrusion from a hidden leak damages the materials it contacts progressively. Wood framing softens and loses structural strength when wet continuously. Concrete that is repeatedly saturated from a slab leak can allow soil erosion below the foundation. Mold growth further degrades the affected materials. Early detection limits structural exposure.
Coverage varies by policy and the cause of the leak. Many policies cover the cost of repairing the damage caused by a sudden or accidental leak but may not cover the cost of finding the leak or repairing the pipe itself. Reviewing your specific policy or contacting your insurer is the most accurate way to determine coverage. Documentation of the leak and its location from a licensed plumber is helpful for claims.
Yes. Thornton Plumbing, HVAC & Electrical detects leaks in main water lines, sewer lines, and supply pipes throughout the home. Sewer line leaks can be identified through odor, slow drains throughout the home, and camera inspection of the sewer line.
Both are possible. Crawl space water can come from rainwater entering through foundation vents or cracks, from groundwater intrusion, or from a plumbing pipe leak inside the crawl space. A plumber can assess whether the water is clean (likely plumbing or rainwater) or contains signs of soil contamination from groundwater intrusion.
Any suspected hidden leak should be investigated promptly. Water that is running continuously into walls, floors, or soil causes progressive damage that compounds over time. A leak that seems minor when first noticed can cause significant structural or mold-related damage if left unaddressed for weeks or months.
Water leak detection and gas leak detection are separate services that use different equipment and procedures. If you suspect both a water leak and a gas leak, gas safety takes priority. Gas leak concerns should be reported immediately and addressed before other plumbing work proceeds. Call 317-697-9265 and describe both concerns when scheduling.
Check the water meter when all fixtures are off. If the meter is still recording flow, water is escaping somewhere. Note any visible symptoms such as damp spots, stains, or odors and where they are located in the home. Shut off the main water supply if you believe the leak is active and significant. Then call Thornton Plumbing, HVAC & Electrical to schedule a leak detection visit.
Yes. Emergency leak detection service is available 24 hours a day. Active or suspected leaks that could cause water damage to the home are treated as urgent calls. Call 317-697-9265 any time for emergency leak detection in Noblesville and surrounding areas.
Yes. Water migrating from a pipe leak inside the wall saturates the drywall and the paint above it. Bubbling or peeling paint on a wall, especially on an interior wall that does not have exterior moisture exposure, is a sign worth investigating for a hidden plumbing leak behind it.
After the leak is precisely located using detection equipment, a targeted access point is made at the confirmed location. The pipe is repaired through that access. The opening is patched after the repair is complete. The goal is the smallest necessary opening rather than removing large sections of drywall to search for the leak.
Leaks in buried supply lines and sewer lines outside the home can be detected using acoustic equipment that listens through the soil surface. Wet areas in the yard, soft spots, or unusual grass color along the path of the buried line are also diagnostic indicators that help locate outdoor leaks.
If the meter still records flow after closing the interior main shutoff, the leak is between the street meter and the interior shutoff valve, which is within the main service line running from the street to the home. That section requires a main water line assessment to locate and repair the leak.
Yes. Hard water with elevated calcium and magnesium content accelerates corrosion of certain pipe materials from the inside. Galvanized steel pipes in older homes corrode faster in hard water conditions, and copper pipes in some soil environments develop pinhole leaks from electrolytic corrosion accelerated by mineral content.
Thornton Plumbing, HVAC & Electrical serves Noblesville, Carmel, Fishers, Westfield, Cicero, Zionsville, Tipton, Anderson, Geist, Castleton, McCordsville, Lapel, and the north Indianapolis area for professional leak detection.
Call 317-697-9265 to schedule leak detection with Thornton Plumbing, HVAC & Electrical. Emergency service is available around the clock. Scheduled assessments are available during regular business hours Monday through Friday 8AM to 6PM.
Checking the water meter at the street while all fixtures inside are off helps isolate where the leak is. If the meter runs while the main interior shutoff is closed, the leak is between the meter and the interior shutoff, which is the main service line. If the meter runs when the interior shutoff is open but everything inside is off, the leak is in the indoor plumbing. A plumber with leak detection equipment can pinpoint the location from there.
