01
Residential Leak Detection
We find leaks in single-family homes and apartments across the Main Street District, from the Factory Street Area to the Water Street Area. Most calls involve hidden pipe leaks behind kitchen walls or under bathroom floors. We use moisture meters and thermal imaging cameras to map the leak without demolition, then repair the pipe and test the line before we leave.
View service →02Commercial Leak Detection
Mixed-use buildings along Main Street and Court Street need leak detection that does not disrupt tenants. We schedule early morning or after-hours inspections, use acoustic listening devices to find leaks in walls shared between businesses, and provide written reports for property managers. Our commercial work covers restaurants, retail spaces, and office buildings in the historic downtown commercial district.
View service →03Slab Leak Detection
Slab leaks are common in Main Street District buildings constructed on concrete slabs during the 1960s and 1970s. We use thermal imaging cameras and acoustic equipment to locate the leak under the slab, then pinpoint the exact spot for repair. Most slab leak detection jobs in the Court Street Area take two to four hours from arrival to diagnosis.
View service →04Pool Leak Detection
A few Main Street District properties have indoor or rooftop pools, and those systems develop leaks at pump fittings, skimmer lines, and return pipes. We use pressure testing gauges and dye testing to isolate the leak, then repair the failed component. Pool leak detection in this area often involves working around building schedules and tenant access.
View service →05Plumbing Leak Detection
Plumbing leaks in Main Street District buildings often start at copper pipe joints or where PEX tubing connects to older galvanized lines. We use electronic leak detection equipment to trace the leak through walls and floors, then repair the pipe with code-correct fittings. Most plumbing leak calls in the Water Street Area are resolved in a single visit.
View service →06Water Line Leak Detection
Water line leaks between the meter and the building are a frequent problem in the Main Street District because many service lines date to the 1940s and 1950s. We use acoustic listening devices and pressure testing gauges to find the leak underground without digging up the whole yard. Repairs typically take three to five hours including excavation.
View service →07Gas Line Leak Detection
Gas line leaks in Main Street District commercial buildings are a safety emergency. We use Sewerin tracer gas detectors and pressure testing gauges to find leaks at fittings, valves, and appliance connections. If you smell gas near the Nashua Public Library or anywhere downtown, call us immediately. We respond 24/7 and coordinate with the fire department when needed.
View service →08Sewer Line Leak Detection
Sewer line leaks under Main Street District streets and sidewalks cause sinkholes and backups. We use pipe inspection cameras to find cracks, root intrusion, and joint failures in cast iron and PVC pipe. Most sewer line inspections in the Court Street Area take 90 minutes, and we provide video footage of the problem for your records.
View service →09Roof Leak Detection
Flat roofs on Main Street District commercial buildings develop leaks at membrane seams and drain flashings. We use moisture meters and thermal imaging cameras to find the leak source, which is often several feet from where water appears inside. Roof leak detection in the historic downtown commercial district requires careful work around HVAC units and parapet walls.

How We Execute Leak Detection in Main Street District
Leak detection in Main Street District requires a different approach than working in newer suburbs. The buildings here are older, the plumbing is a patchwork of materials, and access is often tight. We start every job by reviewing the building layout and asking about recent renovations. Then we use pressure testing gauges to isolate the leaking section. From there, acoustic listening devices and thermal imaging cameras narrow the leak to a specific spot. If the leak is underground, we use tracer gas detectors. If it is behind a wall, we use pipe inspection cameras. We schedule commercial work early morning or after close to avoid disrupting Main Street foot traffic. Residential calls get same-day slots because we keep a truck staged near City Hall. Parking near the Nashua Public Library or the Main Street Bridge can be tight, so we plan our arrival around loading zones and side streets. Every job ends with a pressure test to confirm the repair holds.
Aging copper and galvanized pipe in 19th-century buildings
Old pipes develop pinhole leaks and joint failures that are hard to find without opening walls. The leak may be several feet from where water appears. We use acoustic listening devices and thermal imaging cameras to trace the leak to its source without demolition. Once located, we repair the pipe with code-correct fittings and test the line under pressure.
High foot traffic and limited parking on Main Street
Service calls take longer when we cannot park near the building. Commercial jobs during business hours disrupt tenants and customers. We schedule commercial leak detection early morning or after close. For residential calls, we park on side streets like Factory Street or Court Street and walk equipment in. We also keep a truck staged near City Hall for same-day response.
Mixed-use buildings with shared walls and plumbing
A leak in one unit can affect neighboring businesses or apartments. Finding the source requires access to multiple spaces. We coordinate with property managers to access all affected units. Our technicians use pipe inspection cameras to trace shared lines and identify the exact leak location. We provide written reports for building owners.
NH Master Plumber License requirement
All plumbing work in New Hampshire must be performed by or under the supervision of a licensed master plumber. Our team holds NH Master Plumber licenses, so every repair meets state code.
EPA WaterSense guidelines
WaterSense sets efficiency standards for plumbing fixtures and irrigation systems. We follow these guidelines when recommending repairs or replacements, which helps Main Street District property owners reduce water waste.
Backflow Prevention Certification
Commercial buildings in the Main Street District with irrigation systems or fire sprinklers require backflow prevention devices. Our technicians are certified to test and repair these devices, which is often part of a leak detection inspection.
Common local problems
Common Leak Detection Problems in Main Street District
Main Street District has a unique set of leak problems driven by its age, building stock, and climate. The historic downtown commercial district has some of the oldest plumbing in Nashua. Winters are cold enough to freeze pipes, and summers bring heavy rain that stresses foundations and roofs. Here are the four problems we see most often.
Slab leaks in older commercial buildings
Many Main Street District buildings were constructed on concrete slabs in the 1960s and 1970s. The copper pipes under these slabs corrode over time, especially in areas with aggressive soil. The leak starts small and grows. We use thermal imaging cameras and acoustic listening devices to locate the leak without breaking the slab. Once found, we repair the pipe with code-correct materials and pressure test the line. Most slab leak repairs are completed in one day.
Hidden pipe leaks in mixed-use buildings
Mixed-use buildings have plumbing that runs through shared walls and floors. When a pipe fails, the leak can affect multiple tenants. The source is often hard to find because the plumbing is a patchwork of old and new materials. We use pipe inspection cameras and moisture meters to trace the leak through walls and floors. We coordinate with property managers to access all affected units. Our goal is to find the leak with minimal disruption to tenants.
Underground water line leaks
Many service lines in the Main Street District date to the 1940s and 1950s. These copper and galvanized lines corrode and develop leaks underground. The water may surface in the yard or run along the foundation. We use acoustic listening devices and tracer gas detectors to find the leak without excavation. Once located, we dig only where necessary and repair the line. We backfill and restore the surface when we are done.
Sewer line leaks under downtown streets
Cast iron sewer lines under Main Street and Court Street are vulnerable to cracks, root intrusion, and joint failures. The weight of traffic and the age of the pipes make leaks more likely. We use pipe inspection cameras to find the leak and assess the condition of the line. We provide video footage of the problem and recommend the best repair method, whether that is spot repair or full replacement.
Warning signs
Signs You Need Leak Detection in Main Street District
- Unexplained spike in your water billA sudden increase in water usage usually means a hidden leak in a supply line or a running toilet. In Main Street District buildings, the leak is often underground or behind a wall. We use acoustic listening devices and pressure testing to find it fast.
- Damp spots on floors or ceilingsDamp patches that reappear after you dry them point to a slow leak in a pipe or drain line. In older Main Street District buildings, these leaks can be several feet from where the moisture shows. Thermal imaging cameras help us trace the source without demolition.
- Sound of running water when fixtures are offIf you hear water moving through the pipes when nothing is on, you have a leak. This is common in mixed-use buildings where shared walls carry plumbing. We use acoustic leak detection to pinpoint the exact location.
- Musty odor or mold growth in basementsA persistent musty smell in your basement or crawlspace usually means a hidden leak or foundation leak. In the Main Street District, aging waterproofing and cracked foundation walls are common culprits. We use moisture meters to confirm the source.
- Warm spots on the floorWarm spots on a concrete floor often indicate a slab leak from a hot water line. This is a common problem in Court Street Area buildings with copper pipes under the slab. We use thermal imaging cameras to confirm the leak and locate the repair point.

Factory Street AreaCourt Street AreaWater Street AreaMain Street District Core
Main Street DistrictPrimary local response zone
Factory Street Area
Factory Street Area has a mix of converted industrial buildings and older apartment blocks. The plumbing is a patchwork of copper, galvanized, and PEX. We frequently find hidden pipe leaks behind walls where old and new materials meet. We reach Factory Street Area in 10 to 15 minutes from our staging point near City Hall.
Court Street Area
Court Street Area is home to many mixed-use buildings with commercial space on the ground floor and apartments above. Slab leaks and water heater leaks are common because the buildings are older and the plumbing runs under concrete floors. Court Street Area is a 5-minute drive from our downtown staging area, so we offer same-day appointments.
Water Street Area
Water Street Area has a high concentration of restaurants and retail shops. Grease clogs and sewer line leaks are frequent problems. We also find water line leaks in the older service lines that feed these buildings. We can be on Water Street within 10 minutes for emergency calls, including nights and weekends.
Main Street District Core
The core of the Main Street District includes the historic downtown commercial district and the area around Nashua Public Library.

Local results
Local Case Studies and Results
These are real jobs we have completed in the Main Street District. They show how we find leaks that other contractors miss and how we fix them without unnecessary demolition.
Court Street Area
A Court Street Area restaurant had a slab leak that was driving up the water bill by $400 a month. The owner could not find the source and was considering replacing the entire floor. We used thermal imaging cameras and acoustic listening devices to pinpoint the leak under the slab. The leak was at a copper pipe joint that had corroded. We excavated a 2-foot section, repaired the pipe with a new copper fitting, and pressure tested the line. The repair took four hours and cost $1,200. The water bill dropped back to normal the next month. The owner avoided a $14,000 floor replacement.
Water Street Area
A Water Street Area apartment building had a hidden pipe leak behind a shared wall. Water was staining the ceiling of the business below and the landlord could not find the source. We used a pipe inspection camera and moisture meters to trace the leak to a corroded galvanized pipe in the wall between units. We opened a small access panel, replaced the pipe section with PEX tubing, and sealed the wall. The leak was fixed in three hours. The ceiling stain dried out and the business below did not have to close. The landlord now schedules annual leak detection inspections with us.
Factory Street Area
A Factory Street Area mixed-use building had a water line leak between the meter and the building. The leak was underground and the property manager did not want to dig up the sidewalk. We used acoustic listening devices and tracer gas detectors to find the leak without excavation. Once located, we dug a small trench in the landscaping bed, repaired the copper line, and backfilled. The repair took five hours and cost $1,800. The property manager saved thousands by avoiding a full sidewalk replacement. The water line passed pressure testing before we left.

Sarah L.Water Street Area
Our apartment building on Water Street had a hidden leak that was staining the ceiling below. The landlord called Nashua LeakDetectors and they traced it to a corroded pipe in the wall. They fixed it in one visit and the stain dried up. Professional, on time, and they cleaned up after themselves.
Dave M.Factory Street Area
I manage a mixed-use building on Factory Street. We had an underground water line leak that was wasting water. Nashua LeakDetectors used acoustic equipment to find it without digging up the whole yard. They repaired the line and tested it before they left. Fair price, no surprises.
Plan for the season
Seasonal Leak Detection in Main Street District
Main Street District sees all four seasons, and each one brings different leak concerns. Fall is here now, and winter is coming. Here is what to expect throughout the year.
Spring
Spring thaw and heavy rain expose foundation leaks and roof leaks. Snowmelt can also reveal underground water line leaks that were hidden all winter. We see a spike in calls for foundation leak detection in the Court Street Area.
Summer
Summer heat and heavy thunderstorms stress roofs and irrigation systems. We see more roof leaks in commercial buildings and irrigation system leaks in the Water Street Area. Slab leaks also become more noticeable because the ground shifts.
Fall
Falling temperatures cause pipes to contract, which can worsen existing leaks. We see more hidden pipe leaks and water heater leaks as the heating season starts. This is also the time to winterize irrigation systems.
Winter
Freezing temperatures cause burst pipes and water line leaks. This is our busiest season for emergency leak detection. Older buildings in the Main Street District are especially vulnerable because their pipes are not well insulated.

What to Ask Before Hiring a Leak Detection Company
Not all leak detection companies are the same. Some will sell you a repair you do not need. Others will miss the leak and charge you for a return visit. Here are the questions we recommend asking any contractor before you hire them in the Main Street District.
Are you licensed and insured in New Hampshire?
Leak detection and repair work requires a NH Master Plumber License. If a contractor is not licensed, you have no recourse if something goes wrong. We carry full insurance and can provide proof on request.
What tools do you use to find leaks?
A contractor who only uses visual inspection will miss hidden leaks. We use acoustic listening devices, thermal imaging cameras, tracer gas detectors, and pipe inspection cameras. The right tool makes the difference between finding the leak and guessing.
Do you charge for the inspection if I approve the repair?
Some companies charge a separate inspection fee and then a repair fee. We deduct the inspection cost from the repair if you hire us to fix the leak. That saves you money and simplifies the billing.
How long have you worked in the Main Street District?
Local experience matters. A contractor who knows the building stock and plumbing quirks in the Main Street District will find your leak faster. We have been serving this neighborhood since 2010.
Do you offer emergency service?
Leaks do not wait for business hours. A burst pipe at 2 a.m. needs immediate attention. We offer 24/7 emergency leak detection in Main Street District Nashua, including nights, weekends, and holidays.
