Why Choose Our Leak Detection Team?

When you suspect a leak, you have options. You can call a general plumber, or you can call a company that focuses on finding leaks as accurately and efficiently as possible. As a leak detection company that Redlands property owners turn to, American Leak Detection of San Bernardino is built around one purpose: locating leaks without tearing your property apart.

Our team brings over four decades of focused experience to every job. We are recognized as a world leader in accurate, non-invasive leak detection for homes, businesses, and municipal systems. We combine rigorous training with advanced tools that allow us to listen for leaks, measure pressure changes, and track moisture patterns hidden inside building materials.
Inviting any service provider into your home or business requires trust. Our technicians arrive on time, explain what they are doing, and treat your property with respect. We work carefully, keep work areas as tidy as possible, and clean up when we are done, so you are not left with an avoidable mess.
Cost is another major concern when you suspect a hidden leak. With our “Know Before You Go” approach, we focus on honest, upfront pricing so you understand expected charges before work begins. Because we concentrate on accurate location instead of trial and error, our goal is to help you avoid the expense that often comes with exploratory cutting and repeated repair attempts.

Signs You Need A Leak Inspection

You may not be able to see a broken pipe or drain line, but your property often sends early warning signs. Knowing what to look for can help you decide when it is time to schedule a professional leak inspection.

Common signs tied to hidden leaks include stains or bubbling paint on walls and ceilings, warped or spongy flooring, warm or cold spots on slabs, or areas where tile or hardwood seems to lift for no clear reason. You might hear water running when no fixtures are on, or notice that the water meter continues to move even when all valves inside are closed.

Drain issues can create their own clues. Persistent sewer odors, slow drains in multiple fixtures, repeated backups, or damp soil along buried drain paths can all suggest a drain leak that should not be ignored. These problems can affect both health and structural materials if they continue unchecked.

Outside, you might see unusually green patches of grass, pooling water, or soft spots in soil that stay wet long after irrigation is off. Indoors, a steady rise in your water bill with no change in usage is often a strong indicator of a hidden supply line leak. If you recognize one or more of these symptoms, we encourage you to call our team before authorizing anyone to open walls or break concrete.

Some practical steps you can take before we arrive include:

Turning off all fixtures and checking your water meter to see if it still moves
Noting where you see stains, odors, or moisture so you can point them out to our technician
Avoiding attempts to open walls or floors yourself, which can increase repair costs and spread damage

Our Non-Invasive Detection Process

When you schedule service with American Leak Detection of San Bernardino, our goal is to make the process clear and predictable. We start with a conversation about what you have seen or heard, recent repairs, and any changes in your water usage. This helps us plan the most efficient approach once we arrive at your property.

On-site, our technician performs a visual assessment of affected areas and related plumbing fixtures. From there, we use advanced tools that allow us to narrow down the location of a leak without cutting into surfaces. For pipe leak detection inside walls or under slabs, we may rely on acoustic listening devices that detect the subtle sound of water escaping under pressure.
We can also carry out pressure tests and other non-invasive methods to check whether specific lines are intact. For example, isolating sections of a plumbing system can help us determine whether a leak is located on a hot water line, cold water line, or within a particular branch. Our technician adjusts the testing plan based on what we find, always working to limit disruption.
Throughout the visit, we explain what we are doing and what the results mean in everyday language. Once testing is complete, we identify the most likely leak location as precisely as conditions allow and show you what we have found. We document our findings, then review recommended next steps so you can plan targeted repairs instead of broad exploratory work.

We do not push unnecessary repairs. Instead, we give you information you can share with your plumber, contractor, or maintenance team so they can address the issue with confidence and minimal demolition.

Frequently Asked Questions

How do you find leaks without opening walls?

We use non-invasive tools to narrow down leak locations before any surfaces are opened. Depending on the situation, this may include acoustic listening devices, pressure testing, and other methods. Our goal is to pinpoint the problem so any necessary access can be as small and targeted as possible.

What will plumbing leak detection cost me?

We follow a “Know Before You Go” approach to pricing, so we review costs with you before work begins. Pricing can vary based on property size and system complexity. Our focus is on helping you avoid the higher expenses that come with exploratory demolition and repeated repair attempts.

How long does a typical leak inspection take?

Most visits take between one and three hours, depending on the size of the property and how complex the plumbing system is. Our technician explains the plan when they arrive and keeps you updated as testing progresses, so you know roughly how long we will be on site.

Can your team help with both homes and businesses?

Yes, we provide leak detection for single-family homes, townhomes, apartment buildings, commercial spaces, and municipal properties. Our methods and equipment adapt to different building types, so we can address a wide range of drain, pipe, and wall leak situations in the area.

After you find the leak, what happens next?

After testing, we explain our findings and show you where the leak is most likely located. We provide information you can share with your plumber, contractor, or maintenance staff. This helps them plan targeted repairs instead of broad exploration, which can reduce disruption and overall repair costs.

Small leaks can become major repairs if left unchecked. Our leak detection services in Redlands help identify hidden issues before they worsen. Request an appointment online or call (909) 546-4982.

"Outstanding"
“Outstanding customer service!”

- Sylvia B.
"All conducted themselves in an exemplary manner!"
“I cannot tell you how pleased we were with ALD's work this past week. Your company has assisted us in Palm Springs over the years and also, on occasion, at our main home in Pasadena. As you know, we have quite a unique property and extra care is required to maintain the original 1950's appearance of the home. We were frankly at a loss to find a practical solution to permanently eliminate the risk of our main sewer line clogging as a result of multiple root intrusions. We are also located on a rock ledge, further complicating the challenge. Your team was initially headed by Erick Morales, later joined by his supervisor Andy and as the project unfolded, by several other knowledgeable employees of the firm. All conducted themselves in an exemplary manner and Erick, who had been here in the past, stood out. I even suggested some additional work, yet Erick, once more, provided a more practical solution. Erick also worked very well with our staff. As a former Chief Executive of First Interstate Bank, later the senior Managing Director of what is today JPMorganChase and at present Chairman of the Palm Springs Art Museum, I was struck by your team's "advisory, consultative" approach rather than what is more typical "sales" approach. The team determined the source and location of the problem, discussed various alternatives, brought in experts, arrived at a workable solution which was then followed by a proposal. That proposal was executed to the letter, within budget and in a timely fashion. We would be most pleased to serve as a reference should this be helpful. It was a pleasure to meet you during the process.”

- Harold M.
"Prompt, thorough and completely professional."
“Please allow this letter to serve as our recommendation for American Leak Detection. We have used the services of this company on countless occasions over the many years, and we have always found them to be prompt, thorough and completely professional. A few years ago we had a string of leaks which had gone undetected during the summer months and had caused a tremendous amount of damage, including mold. Jimmy Carter and American Leak Detection came to our assistance immediately and solved the problems in a timely and competent manner. I might also add the office staff is always very courteous and helpful. We will continue to use the services of American Leak Detection in the future.”
