Leak Detection in Norcross Finds Hidden Leaks Fast

Serving Norcross homes and businesses since 2000

Leak Detection in Norcross starts with a simple question: where is the water going? Our technicians use acoustic leak detection equipment and thermal imaging cameras to pinpoint hidden plumbing leaks behind walls, under slabs, and beneath Norcross lawns. We have served this Georgia community for 26 years, and we find the leak before we open a single wall. One visit, one clear answer.

Leak Detection in Norcross, Done Right

Norcross sits in Gwinnett County, where the housing stock ranges from 1960s ranch homes near downtown to new construction along Peachtree Industrial Boulevard. That mix means we see everything: copper pipe that has pinhole leaks after decades of Gwinnett County water, PEX tubing in newer builds, and irrigation systems that quietly drain a yard all summer. Leak Detection in Norcross is not a one-tool job. We carry acoustic leak detection equipment, a thermal imaging camera, and a video pipe inspection camera on every truck, because the leak you hear is rarely the leak you can see. Our technicians are trained on Sewerin and FLIR gear, and we hold a Georgia State Plumbing License. Whether you are in the historic downtown district or a subdivision off Beaver Ruin Road, we treat a high water bill like the emergency it is. We have worked this area for 26 years, and we know how Norcross homes are built, plumbed, and where they fail.

Norcross has a specific leak profile. The city's older downtown blocks still run copper pipe and cast iron drains, while the corridors near Jimmy Carter Boulevard and Buford Highway carry heavy commercial water demand from restaurants, laundries, and warehouses. That combination keeps our phone ringing. Summer irrigation leaks spike from June through September. Winter brings slab leaks as Gwinnett County's clay soil shifts with temperature swings. We serve Norcross because the demand is real and the housing stock rewards a technician who knows how to read it.

Find Us in Norcross

Pro Leak Detection opened in 2000, back when Norcross was still mostly known for its antique shops and the train depot on South Peachtree Street. We started with one truck and a Sewerin acoustic unit. Word spread through the downtown merchants and the neighborhoods off Holcomb Bridge Road. Twenty-six years later we run multiple trucks across Gwinnett County, and Norcross is still one of our core service areas. Many of our first customers here are now on their second or third home, and they still call us first when the water bill jumps.

Leak Detection Services Available in Norcross

Norcross leak detection demand splits roughly three ways: residential slab and water line leaks, commercial irrigation and sewer line problems, and pool leaks in the neighborhoods around Norcross High. We handle all of it. If you are searching for a leak detection company near me in Norcross, our trucks are already in the area most weekdays. Every job starts with a non-invasive survey, and we tell you what we find before we quote a repair.

Water Leak Detection

Water leak detection in Norcross usually means a hidden plumbing leak behind a wall or under a cabinet. We use acoustic listening equipment and a moisture meter to trace the source without tearing out drywall. Common in the older homes near downtown Norcross, where copper pipe has been in service for 40-plus years.

Water Leak Detection

Pool Leak Detection

Pool leaks in Norcross show up as a water bill that climbs while the pool level drops. We pressure test the plumbing lines, check the skimmer and light niches, and use leak detection dye to confirm the breach. Most pool leaks we find in the Norcross area are in the underground return lines, not the shell.

Pool Leak Detection

Slab Leak Detection

Slab leaks are common in Norcross ranch homes built between 1965 and 1985, where copper supply lines run under the concrete. We use acoustic leak detection equipment and thermal imaging to pinpoint the break before any concrete is cut. If your floor is warm in one spot, call us. That is a slab leak signature.

Slab Leak Detection

Underground Leak Detection

Underground water leaks in Norcross often trace to the main line between the meter and the house. Gwinnett County's clay soil shifts and stresses buried pipe. We use a pipe locator and tracer gas leak detector to follow the line and mark the failure point, so excavation stays small and targeted.

Underground Leak Detection

Plumbing Leak Detection

Plumbing leak detection covers the whole system: supply lines, drain lines, fixtures, and shutoff valves. In Norcross we see a lot of failures at pipe fittings and solder joints in homes that have never been repiped. We test with a pressure testing gauge and inspect with a video pipe inspection camera when the drain side is suspect.

Plumbing Leak Detection

Roof Leak Detection

Roof leaks in Norcross tend to appear after summer storms and during winter freeze-thaw cycles. We trace the entry point with moisture meters and infrared cameras, then confirm whether the water is coming from a failed flashing, a cracked pipe boot, or a roof leak that is actually a plumbing vent leak. Norcross homes with mature tree cover see more of these.

Roof Leak Detection

Gas Leak Detection

Gas leak detection in Norcross is emergency work. If you smell gas, leave the building and call us from outside. We use an electronic leak detector and tracer gas equipment to find the source on gas lines, appliances, and fittings. Our technicians carry OSHA Safety Certification for this work, and we coordinate with the gas utility when needed.

Gas Leak Detection

Sewer Line Leak Detection

Sewer line leaks in Norcross show up as soggy patches in the yard, sewage odor, or repeated drain backups. We run a video pipe inspection camera through the line to find cracks, root intrusion, and joint failures. Older Norcross properties with cast iron or clay sewer pipe are the most common callers.

Sewer Line Leak Detection

Water Line Leak Detection

Water line leaks between the meter and the house are a frequent Norcross problem, especially on properties with long driveways and mature landscaping. We use acoustic equipment and a pipe locator to trace the line and mark the leak. Repair usually means one targeted excavation, not a trench across the whole yard.

Water Line Leak Detection

Irrigation System Leak Detection

Irrigation leaks in Norcross run from April through October and can waste hundreds of gallons a week. We pressure test each zone, check the backflow assembly, and locate broken lateral lines and failed valves. If one zone is losing pressure or a section of lawn stays green while the rest dries out, that is your leak.

Local Expertise

How Leak Detection Works in Norcross

When we run leak detection in Norcross, we start outside. We read your water meter with every fixture off. If the dial moves, you have a live leak. From there we isolate zones: irrigation first, then the main line, then the house. Inside, we use acoustic leak detection equipment to listen through the slab or wall, and a thermal imaging camera to spot temperature differences where water is moving. For underground work, a tracer gas leak detector and pipe locator let us follow the line without digging blind. Norcross has a lot of slab-on-grade construction, so we lean on non-invasive methods before we ever recommend opening a floor. We schedule around your day, and we can work around Gwinnett County school pickup traffic on Beaver Ruin Road and Jimmy Carter Boulevard. Most residential leak surveys take 60 to 90 minutes. If we find the leak, we show you the evidence on the meter, the camera, or the thermal image before we quote the repair.

1

Gwinnett County clay soil shifting with moisture

We use a pipe locator and tracer gas leak detector to map the line before excavation, so we open one small area instead of trenching the yard. We also check soil movement around the meter box, which is often the first place clay stress shows up.

2

Aging copper supply lines under slab

We use acoustic leak detection equipment and a thermal imaging camera to pinpoint the break under the slab. That lets us recommend a targeted repair or reroute instead of breaking out a large section of floor.

3

Heavy commercial water use along Jimmy Carter Boulevard

We schedule commercial leak surveys before opening hours or after close, so we do not disrupt business. We pressure test the system in sections and use an electronic leak detector to isolate the loss without shutting down the whole building.

Service Areas

Norcross Neighborhoods We Serve

Beaver Ruin Corridor

Our water bill jumped from $60 to $190 in one month. Pro Leak Detection came out the same day and found a slab leak under our kitchen using a thermal camera. They showed me the image before they quoted anything. Rerouted the line through the attic and we never had to tear up the floor. Honest work.

— Marcus T.

Peachtree Corners Edge

I was sure our pool was leaking because the level dropped every week. They pressure tested the lines, found a cracked return line underground, and fixed it without draining the pool. Also checked our backflow assembly while they were here. Fair price and no upsell.

— Dana R.

Historic Downtown Norcross

We had a sewer smell in the backyard and two plumbers told us we needed a full line replacement. Pro Leak Detection ran a camera through the line and found one cracked joint, not a collapsed pipe. They repaired the joint and saved us thousands. I appreciated that they showed us the video.

When To Call

Signs You Need Leak Detection in Norcross

Most Norcross homeowners call us after the water bill arrives, not before. By then the leak has usually been running for weeks. If you know what to watch for, you can catch it earlier and spend less on the repair. Here are the signs we see most often in this area, and what each one usually means.

1. Water bill jumped with no usage change

A sudden increase in your Gwinnett County water bill is the single most reliable sign of a hidden leak. If your usage habits have not changed, water is escaping somewhere between the meter and your fixtures. Check the meter with everything off. If the dial moves, call us.

2. Warm spot on the floor

A warm patch on a slab floor usually means a hot water line is leaking under the concrete. The hot water heats the slab from below. This is a classic Norcross slab leak signature, and it will not fix itself. The longer it runs, the more damage the slab and flooring take.

3. Sound of running water at night

If you hear water moving when every fixture is off, you have a live leak. It could be a toilet flapper, an irrigation valve, or a line under the slab. We isolate the source with acoustic equipment and confirm it before recommending any repair.

4. Soggy patch in the yard

A persistently wet or unusually green patch in the lawn often marks an underground water or sewer line leak. In Norcross, clay soil holds that moisture and makes the patch obvious. Do not ignore it. A small line break can wash out soil and create a sinkhole.

5. Musty smell or unexplained mold

A musty odor in a room with no obvious water source usually means a slow leak inside a wall or under a floor. Mold follows moisture. If you smell it, we can trace the source with a moisture meter and infrared camera before it spreads further.

Local Problem Patterns

Common Leak Problems in Norcross

Norcross has a specific set of leak problems that come from its housing age, soil, and climate. Gwinnett County's clay soil moves with the seasons, the older housing stock still runs copper under slabs, and the commercial corridors put heavy demand on water and sewer lines. Those three factors drive most of the calls we get here.

Slab leaks in 1970s and 1980s ranch homes

Why it happens here

Copper supply lines under the slab in these homes have been in service for 40-plus years. Gwinnett County water chemistry and soil movement stress the pipe until a pinhole opens. The leak runs silently under the concrete until the floor warms or the bill spikes.

Our approach

We confirm the leak with acoustic equipment and a thermal imaging camera before recommending any concrete work. In many cases we can reroute the line through the attic and leave the slab intact, which saves the flooring and thousands in repair cost.

Underground water line failures in clay soil

Why it happens here

Norcross sits on clay-heavy soil that expands when wet and contracts when dry. That cycle puts stress on the main water line between the meter and the house. Failures often show up after a dry spell followed by heavy rain, when the soil moves the most.

Our approach

We use a pipe locator and tracer gas leak detector to map the line and mark the failure point before excavation. That keeps the dig small and targeted instead of trenching the whole yard.

Irrigation leaks during summer watering season

Why it happens here

Norcross irrigation systems run hard from April through October. Zone valves fail, lateral lines crack, and backflow assemblies start to weep. A single broken head or valve can waste hundreds of gallons a week without any visible sign above ground.

Our approach

We pressure test each zone individually and check the backflow assembly at the same time. Most irrigation leaks we find here are one failed valve or one broken lateral, not a system-wide failure. We fix the specific problem and verify the rest of the zones hold pressure.

Sewer line leaks in older cast iron and clay pipe

Why it happens here

Older Norcross properties still have cast iron or clay sewer laterals. These materials crack, shift, and invite root intrusion. The leak may not back up the drain for months, but it sends sewage into the soil and can create a health hazard.

Our approach

We run a video pipe inspection camera through the line to see the exact failure. If it is a single cracked joint or a root intrusion, we can often repair that section instead of replacing the whole lateral. We show you the camera footage before we quote.

Year-Round Coverage

How Seasons Affect Leak Detection in Norcross

Norcross weather drives a clear seasonal pattern in leak calls. Fall is when we start seeing slab leaks as the soil cools and shifts. Winter brings freeze-related pipe failures. Spring and summer belong to irrigation and pool leaks. Knowing what to expect each season helps you catch a problem before it becomes expensive.

Spring

Spring is irrigation startup season in Norcross. Systems that sat idle all winter often develop valve failures and cracked lateral lines when they are pressurized for the first time. We also see water line leaks as spring rain saturates the clay soil and shifts buried pipe.

Tip

Run each irrigation zone for five minutes and watch for low pressure or a zone that will not hold. If one zone behaves differently, call us before the summer watering season starts.

Summer

Summer is peak irrigation and pool leak season in Norcross. Daily watering exposes failing valves and broken heads. Pool levels drop faster in the heat, so a small leak becomes obvious. Water bills climb, and that is often when homeowners call us.

Tip

Check your pool level weekly against a marked line. If you are adding more than an inch of water per week with normal evaporation, you have a leak. Call us for a pressure test.

Fall

Fall is when slab leaks start showing up in Norcross. As the ground cools and the clay soil contracts, copper lines under slabs are stressed. A warm spot on the floor or a rising water bill in October and November is a common pattern here.

Tip

Walk your floors barefoot and feel for warm spots. If you find one, call us before winter. A slab leak caught early can often be rerouted instead of repaired under the concrete.

Winter

Winter freeze events in Norcross can crack exposed pipes in crawlspaces, garages, and exterior walls. Even a brief hard freeze can split a copper line. We also see gas leak calls rise in winter because heating systems run constantly and fittings are under more stress.

Tip

Before the first freeze, disconnect garden hoses and insulate exposed pipes in the garage and crawlspace. If you smell gas at any point, leave the building and call us from outside.

Leak Detection in Norcross: Common Questions

Common questions before hiring a Leak Detection in Norcross

How much does leak detection cost in Norcross?

Most residential leak detection in Norcross runs $180 to $450 in 2026, depending on how many systems we need to isolate. A simple irrigation or water line leak sits at the low end. A slab leak that requires acoustic and thermal confirmation sits at the high end. We quote the fee before we start, and we credit it toward the repair if you hire us.

How long does leak detection take?

A standard residential survey takes 60 to 90 minutes. If we need to isolate multiple systems, such as irrigation, main line, and slab, it can run closer to two hours. Commercial leak detection takes longer because building size and system complexity vary. We give you a realistic time window when you book.

Can you find a leak without breaking into walls or floors?

Yes. We use acoustic leak detection equipment, a thermal imaging camera, and a video pipe inspection camera to locate leaks without demolition. We confirm the source and show you the evidence before recommending any repair. In many Norcross slab leak cases, we can reroute the line through the attic and leave the floor untouched.

Do you handle emergency water leaks in Norcross?

Yes. If you have an active water leak flooding a floor or a suspected gas leak, call us immediately. We prioritize emergency calls and route the closest truck. For gas leaks, leave the building and call us from outside. We carry OSHA Safety Certification and coordinate with the gas utility when needed.

What causes slab leaks in Norcross homes?

Most slab leaks in Norcross happen in homes built between 1965 and 1985 with copper supply lines under the concrete. Gwinnett County's clay soil shifts with moisture changes, and that movement stresses the pipe until a pinhole opens. Water chemistry also plays a role. We confirm the leak with thermal imaging before recommending any concrete work.

Norcross is compact, but the landmarks matter when we are routing trucks and giving arrival windows. We use the historic train depot on South Peachtree Street as our downtown anchor. Lillian Webb Park is a common meeting point for customers in the center of town. Further out, the Forum on Peachtree Parkway and the Jimmy Carter Boulevard commercial strip help us orient quickly. When you call, we can usually tell you which truck is closest to your landmark and give you a realistic arrival time instead of a vague window.

Landmarks

  • Norcross Train Depot

    The historic depot on South Peachtree Street is our downtown reference point. Customers near the depot are usually in the older housing stock, which means we bring extra acoustic and thermal gear for hidden leak work.

  • Lillian Webb Park

    This park sits in the center of Norcross and is a convenient meeting point for customers in the downtown grid. We often stage nearby for multiple calls in the historic district on the same day.

  • The Forum on Peachtree Parkway

    The Forum is a major retail and dining destination just outside Norcross. Commercial leak calls in that corridor often involve irrigation and sewer line work, and we route trucks through Peachtree Parkway to reach them.

Commercial Districts

  • Jimmy Carter Boulevard Commercial Corridor

    This strip carries restaurants, auto shops, laundries, and retail. Water demand is high, and small leaks turn into big bills fast. We do most commercial leak surveys here before opening hours to avoid disrupting business.

  • Peachtree Industrial Boulevard Business District

    Warehouses, offices, and light industrial buildings line this corridor. Leak detection here focuses on main water lines, irrigation, and sewer laterals. We schedule after-hours work so tenants and employees are not affected.

Transport & Access

  • I-85 at Jimmy Carter Boulevard

    This interchange is our main access point to Norcross from the south and west. It puts us within minutes of the Jimmy Carter commercial corridor and the neighborhoods behind it.

  • Peachtree Industrial Boulevard

    Peachtree Industrial is our primary north-south route through Norcross. It connects us to the Beaver Ruin corridor, the Peachtree Corners edge, and the business district along the boulevard.
