A hidden irrigation leak can waste thousands of gallons of water per month and quietly damage your landscape from below the surface. For homeowners in Preston Hollow, University Park, and other established Dallas neighborhoods, the signs often show up as unexplained wet spots, sudden pressure drops, or sections of turf that look healthier than everything around them. When that happens, finding a reliable irrigation leak detection Dallas specialist quickly matters, both for your water bill and for the long-term health of your landscape.
At Greenform Landscapes, irrigation system repair is a core part of what we do across the Dallas–Fort Worth area. We’ve seen firsthand how a small leak left unchecked can erode soil, compromise drainage, and stress root systems in ways that take seasons to correct. That experience also means we know who else does strong work in this space, and we believe homeowners deserve honest options when they need fast, accurate leak detection.
This guide covers eight Dallas-area irrigation professionals worth contacting in 2026, including what each one brings to the table and how to evaluate the right fit for your property.
1. Greenform Landscapes
Greenform Landscapes is a Dallas-based company that handles irrigation system diagnostics, repair, and optimization as a core service for residential properties across the area. Unlike general contractors who treat irrigation as a side task, Greenform approaches every system as part of a connected property ecosystem, where a leak in one zone can create drainage problems, soil erosion, and plant stress well beyond the immediate area. That context shapes how every inspection is handled.
What they typically check first on Dallas irrigation leaks
When a Greenform technician arrives on a property, the first step is a full system walk-through before any zone isolation begins. This means checking the controller settings, inspecting each zone for pressure consistency, and looking for surface indicators like wet soil patches, sunken turf, or unusually green grass concentrated in specific areas.
Pressure testing individual zones early in the diagnostic process often reveals the source of water loss faster than visual inspection alone.
In clay-heavy Dallas soils, leaks tend to saturate from below rather than pool on the surface immediately. Identifying which zone is losing pressure helps narrow the search significantly before any ground is disturbed.
When Greenform makes the most sense to call
Greenform is the right call when the leak appears connected to the broader landscape system rather than a simple broken head or cracked valve. If your property has mature trees, established planting beds, or an older irrigation setup with multiple zones, the diagnostic requires someone who understands how those elements interact across the full system.
Properties in established neighborhoods like Preston Hollow and Bluffview often have irrigation systems that have been modified or expanded over the years, creating inconsistencies that are difficult to trace without system-level knowledge. Greenform’s experience with irrigation leak detection in Dallas on complex residential properties makes these situations a strong fit, especially when the diagnostic needs to account for landscape impact, not just the pipe itself.
Typical pricing factors and what to ask up front
Greenform’s pricing for leak detection and repair depends on several variables, including the size of the system, the number of zones involved, and whether the leak requires excavation. Diagnostic visits typically involve a flat inspection fee, with repair costs quoted after the source is confirmed.
Before scheduling, it helps to ask:
- How many zones does the inspection cover, and is that included in the base fee?
- Will the technician confirm the leak source before any repair work begins?
- If excavation is needed, is that billed separately or included in the repair estimate?
Getting clear answers to these questions upfront prevents billing surprises and helps you compare quotes accurately across providers. Greenform’s approach prioritizes transparency at the estimate stage, which is worth confirming when you contact them directly.
2. Lawn Sense Texas
Lawn Sense Texas is a Dallas-area irrigation and lawn care company that handles irrigation system diagnostics as part of its core service offering. Their technicians work across residential properties and are familiar with North Texas soil conditions and the way clay-heavy ground can mask water loss until significant damage has already occurred.
Detection methods they emphasize and when they help
Lawn Sense Texas focuses on zone-by-zone pressure testing and visual inspection to identify where a system is losing water. Their process typically involves running each zone independently and measuring how the system responds under normal operating pressure. When pressure drops or fluctuates across specific zones, that pattern often points directly to where the leak is occurring without requiring extensive excavation.
Pressure-based isolation testing is one of the most reliable methods for narrowing down a leak location before any digging begins.
Best fit for hidden leaks and hard-to-find water loss
Lawn Sense Texas tends to be a strong fit when standard visual inspection has not produced a clear answer. If you’ve already checked your heads and valves without finding obvious damage, their diagnostic process is structured to go deeper into the system. For properties with older irrigation layouts or multiple zone modifications, this methodical approach can surface problems that would otherwise go undetected for months.
Typical pricing factors and what to ask up front
Pricing at Lawn Sense Texas depends on the scope of the diagnostic and whether repairs are needed during the same visit. Before scheduling, it’s worth asking a few questions to set clear expectations:
- Does the base inspection fee cover all zones, or is there an additional charge per zone?
- Will you receive a written estimate before any repair work begins?
- Is the work under a service warranty if the same issue returns after repair?
Getting these details confirmed upfront helps you compare quotes and avoid unexpected costs, which matters whether you’re evaluating Lawn Sense Texas or any other irrigation leak detection Dallas provider.
3. American Leak Detection of Dallas
American Leak Detection is a national franchise with a Dallas location that focuses specifically on leak detection as a standalone service. Rather than combining detection with general irrigation maintenance, their technicians concentrate on locating where water is escaping using specialized equipment before any repair work begins. This separation of detection from repair can be useful when you need an independent diagnosis on a property where the source of water loss is unclear.
How their non-invasive process usually works
Their approach relies on acoustic listening equipment and ground microphones to trace water movement below the surface without opening up the ground first. Technicians run the system and listen for the frequency changes that indicate active water loss underground. This process allows them to pinpoint leak locations with significant accuracy before any soil is disturbed or any trench is opened.
Non-invasive detection methods reduce the risk of unnecessary excavation and can save considerable repair costs when the leak location is confirmed in advance.
Best fit for suspected underground or slab-adjacent leaks
American Leak Detection tends to be the right call when you suspect the problem is deep underground or running near a structure. If your irrigation mainline passes close to your foundation, a driveway, or a patio, standard visual inspection will not reach it. Their equipment is designed to detect leaks in pressurized lines buried several feet below grade, which is where most conventional irrigation firms stop their diagnostic process.
Typical pricing factors and what to ask up front
Their pricing typically reflects the complexity of the detection work rather than the size of your irrigation system. Because American Leak Detection focuses on diagnosis rather than repair, you should confirm upfront whether they coordinate with your irrigation contractor for the actual fix. Key questions to ask include:
- Does the detection fee cover a written report with the confirmed leak location?
- Do they handle irrigation-specific lines, or is their focus primarily on plumbing and supply lines?
4. CMH Plumbing
CMH Plumbing is a Dallas-area plumbing company that handles residential and commercial water line issues, including leak detection and repair. While they are not an irrigation-specific firm, they are equipped to address water loss problems that start at the supply side of your system, which is where some irrigation leaks actually originate.
How plumbing-based leak detection differs from irrigation firms
Plumbing contractors approach leak detection from the water supply perspective rather than the zone and head perspective that irrigation specialists use. CMH Plumbing focuses on identifying failures in pressurized supply lines, backflow preventers, and mainline connections rather than individual sprinkler zones or lateral pipe runs. This distinction matters because some leaks are not inside your irrigation system at all. They occur at the connection point between the municipal supply line and your irrigation controller, which falls squarely in plumbing territory.
When a leak sits at the supply side of your system, an irrigation contractor may not have the licensing or equipment to address it directly.
Best fit for mainline, backflow, or supply-side concerns
CMH Plumbing is worth calling when standard irrigation leak detection Dallas diagnostics have ruled out zone-level failures but water loss continues. If your backflow preventer is leaking, your mainline shutoff is failing, or you are seeing water loss even when the irrigation controller is off, the problem likely sits upstream of the irrigation system itself. In those situations, a licensed plumber is the appropriate first call.
Typical pricing factors and what to ask up front
Pricing at CMH Plumbing reflects the scope of the diagnostic and the type of repair involved. Supply-side work often requires licensed plumbing permits, which can affect both cost and timeline. Before scheduling, confirm the following:
- Is the diagnostic fee separate from any repair estimate?
- Will they coordinate with your irrigation contractor if the repair crosses into system territory?
- Does the quote include any permit fees required for supply-line work?
5. NxTGen Irrigation and Landscape Management
NxTGen Irrigation and Landscape Management is a Dallas-area company that handles irrigation system diagnostics, repair, and ongoing maintenance for residential properties across North Texas. Their technicians work with both standard and more complex multi-zone systems, making them a reasonable option when your irrigation problem extends beyond a single broken head or obvious surface failure.
How they approach irrigation diagnostics and isolation testing
NxTGen uses zone isolation testing as a primary diagnostic method, which involves shutting down individual zones to determine where pressure is dropping and water is being lost. This approach allows their technicians to identify the affected section of the system without opening up areas that are functioning normally. Running each zone separately under operating pressure gives a clearer picture of where the system is underperforming before any physical repairs begin.
Isolation testing is one of the most efficient ways to localize a leak in a multi-zone system without unnecessary excavation.
Best fit for zone-specific pressure loss and wet spots
NxTGen tends to be a good fit when your property has identifiable symptoms tied to specific zones, such as a wet spot that only appears after a certain zone runs, or a section of turf that stays consistently saturated. For irrigation leak detection Dallas homeowners who have narrowed the problem to one area of the property but cannot confirm the exact source, their diagnostic process is well-suited to that kind of targeted investigation. Their familiarity with North Texas soil conditions also helps when interpreting how clay-heavy ground absorbs and hides water loss beneath the surface.
Typical pricing factors and what to ask up front
Pricing at NxTGen depends on the number of zones inspected and whether repairs are completed during the same visit. Before scheduling, confirm a few key details:
- Is the diagnostic fee separate from repair costs?
- Will you receive a written estimate before work begins?
- Does the quote cover full system testing, or only the zone you suspect?
6. AquaPros Irrigation
AquaPros Irrigation is a Dallas-area irrigation company that handles system diagnostics, repair, and performance optimization across residential properties in North Texas. Their technicians focus specifically on irrigation systems, meaning their diagnostic process is built around how sprinkler systems behave rather than treating water loss as a general plumbing problem.
What their leak detection and repair workflow often includes
The diagnostic process at AquaPros typically begins with a full system run-through to identify where pressure inconsistencies or visible surface symptoms appear before moving into more targeted testing. Their workflow connects detection directly to repair, meaning the technician who diagnoses the problem is often the same one completing the fix. This continuity helps avoid the gaps that can appear when detection and repair are handed off between different crews.
When detection and repair are handled by the same technician, the diagnostic findings translate directly into more accurate repair decisions.
Their process also includes a check of valve function and controller settings, which can sometimes reveal that what appears to be a leak is actually a failed solenoid or programming error creating pressure irregularities that closely mimic active water loss.
Best fit for ongoing irrigation performance problems
AquaPros tends to work well for homeowners dealing with recurring irrigation issues rather than a single isolated failure. If your system has had repeated wet spots, inconsistent zone coverage, or pressure problems across multiple seasons, their approach to irrigation leak detection Dallas properties is structured to address the root cause rather than just the immediate symptom. They are particularly suited to situations where performance has gradually declined and no single obvious failure point has been identified.
Typical pricing factors and what to ask up front
Their pricing depends on the size of the system and the scope of repairs identified during the diagnostic visit. Before scheduling, confirm the following details:
- Is the diagnostic fee applied toward any repair costs?
- Do they provide a written estimate before starting repair work?
- Does the quote cover all affected zones or only the area you reported?
7. A Star Plumbing
A Star Plumbing is a licensed Dallas plumbing company that handles residential water line diagnostics and repair, including situations where water loss appears connected to the supply side of your property rather than the irrigation zones themselves. Their technicians are licensed to work on pressurized municipal and private water lines, which places them in a different category from irrigation-specific firms.
When a plumber is the right call for irrigation leaks
Not every leak that affects your irrigation system originates inside it. If your water meter is running when the controller is off, or if you are seeing water loss that does not correspond to any specific zone or run cycle, the problem may sit upstream of the irrigation system entirely. A Star Plumbing is equipped to test and diagnose supply-side failures that fall outside the scope of what most irrigation contractors are licensed to address.
When your irrigation controller is off and water loss continues, the source is often in the supply line or a shutoff component rather than the irrigation system itself.
Best fit for water line leaks and shutoff-related issues
A Star Plumbing is worth contacting when irrigation leak detection Dallas diagnostics have already confirmed that the system itself is functioning correctly but water loss persists. If your main shutoff valve is failing, your service line has developed a slow leak, or a connection near the meter box is compromised, a licensed plumber is the appropriate professional to call rather than an irrigation technician.
Typical pricing factors and what to ask up front
Pricing at A Star Plumbing reflects the type of repair and whether permit work is required for supply-line access. Before scheduling, confirm the following:
- Is the diagnostic visit separate from the repair estimate?
- Will they provide documentation if permit fees apply to the work?
- Can they coordinate with your irrigation contractor if the repair crosses into system territory?
8. Legacy Plumbing
Legacy Plumbing is a Dallas-area licensed plumbing company that handles residential water loss diagnostics and repair, including situations where leaks are occurring underground or in pressurized lines that fall outside the scope of an irrigation system. Their technicians are equipped to work on buried supply lines and service connections that require licensed plumbing access rather than irrigation-specific tools, which places them in a different category from most irrigation contractors.
How they typically locate underground water leaks
Legacy Plumbing uses acoustic detection equipment and pressure testing to identify where water is escaping below grade. Their technicians pressurize the suspect line and then use ground-level listening tools to pick up the frequency shifts that indicate active water movement underground. This approach lets them confirm the leak location before opening the ground, which reduces the amount of excavation needed to complete the repair and limits disruption to the surrounding property.
Confirming a leak location acoustically before any digging begins typically reduces repair time and limits disruption to the landscape around it.
Best fit for urgent water loss and high-bill situations
Legacy Plumbing is most useful when you are dealing with a sudden and significant spike in your water bill that does not correspond to your irrigation system’s run schedule. If your meter is running continuously or usage has jumped with no clear explanation, their diagnostic process is designed to isolate the source quickly and move toward repair without delay. For homeowners who have already exhausted standard irrigation leak detection Dallas diagnostics without finding the problem, Legacy Plumbing is a reasonable next step when a supply-side failure is suspected.
Typical pricing factors and what to ask up front
Pricing at Legacy Plumbing reflects the depth and location of the leak and whether permit work is required for supply-line access. Before scheduling, confirm the following details:
- Is the diagnostic fee applied toward the repair cost if you proceed?
- Will they provide a written estimate before any work begins?
- Do permit fees apply, and are they included in the quoted price?
A simple way to choose who to call
The right call depends on where the problem is sitting. If your symptoms point to a specific zone, a wet spot tied to a run cycle, or pressure loss in one area of the property, an irrigation-specific firm is the right starting point. If your meter is running with the controller off, or if previous diagnostics have ruled out the irrigation system itself, a licensed plumber is the more appropriate first step. For complex properties with older systems and multiple zones, a company experienced in irrigation leak detection Dallas diagnostics across full-system evaluations will save you time compared to working zone by zone on your own.
Start with the symptoms you can observe, confirm what type of professional matches the problem, and ask each provider the same questions upfront so you can compare answers clearly. If you want guidance specific to your property, request a consultation to get a direct assessment from Greenform Landscapes.
