The Leak You Can't See Is the One That Costs the Most
A faucet dripping in the kitchen is obvious. A supply line leaking inside a wall cavity is not. By the time you notice a wet spot on the wall, a damp patch on the floor, or water coming through the ceiling, the leak may have been running for days or weeks. That hidden damage is where the real cost lives.
Bailey Bros. Plumbing & Drain Services provides professional leak detection and leak repair for homes across Central Maryland. We use electronic leak detection and thermal leak detection equipment to locate leaks behind walls, under concrete slabs, in ceilings, and underground without tearing your home apart to find them. Once we locate the source, we repair it the same visit in most cases.
According to the EPA, mold can begin growing on damp materials within 24 to 48 hours of water exposure. A hidden leak that runs for days or weeks creates the ideal conditions for mold growth behind walls, under flooring, and inside wall cavities. Finding and fixing the leak quickly is the most effective way to prevent a water damage and mold remediation situation that costs far more than the repair itself.
We respond 24/7 to emergency leak calls. Our team is led by a licensed Master Plumber with 28 years of experience, and every repair is backed by a 1-year labor warranty. Financing is available through Wisetack for larger repairs. If the leak has already caused water damage, we handle the full remediation in-house.

Signs You Have a Hidden Water Leak
If your water bill jumps without a change in usage, water is going somewhere you can't see. A running toilet, a dripping supply line, or an underground water main leak can waste hundreds of gallons a day without any visible sign inside the house.
A water stain on the ceiling or a damp patch on a wall usually means a pipe or supply line is leaking behind or above the surface. The visible stain is often smaller than the actual area of damage behind it.
A damp spot on a floor that shouldn't be wet, or a warm spot on a concrete slab, can indicate a hot water supply line leaking under the foundation. Slab leaks are one of the most damaging types of hidden leaks because the water has nowhere to go but into your foundation.
A persistent musty smell in a room with no obvious water source is a strong indicator of a hidden leak feeding mold growth behind the wall, under the floor, or in a crawl space. Mold from a hidden leak can spread for weeks before it becomes visible.
If you can hear water moving through pipes when no fixtures are in use, water is flowing somewhere it shouldn't be. This is one of the clearest signs of an active leak in a supply line, water main, or toilet.
A sudden drop in pressure throughout the house, rather than at one fixture, can mean a supply line or water main has developed a significant leak. The water is leaving the system before it reaches your fixtures. Water line repair may be needed.
Leak Detection & Repair Services
Electronic Leak Detection
We use acoustic listening equipment and electronic sensors to pinpoint leaks behind walls, under slabs, and in underground lines without destructive exploration. Electronic leak detection lets us find the exact location before we open anything, saving time and limiting damage to your home.
Slab Leak Detection & Repair
A leak under a concrete slab is one of the most difficult to find and most expensive to ignore. We locate the leak using detection equipment, then determine the best repair approach: spot repair through the slab, reroute of the line above the slab, or full replacement. The right method depends on the pipe material, age, and condition. For complex cases, underslab plumbing may be required.
Pipe Leak Repair
Pinhole leaks in copper pipe, failed fittings on CPVC, cracked supply lines, and corroded joints. We repair the damaged section and assess whether the rest of the system is at risk. If pinhole leaks are appearing in multiple locations, repiping may be the more cost-effective long-term solution.
Underground & Water Main Leak Repair
A water main leak between the meter and the house can waste enormous amounts of water and undermine your foundation or landscaping. We locate the leak, excavate to the failure point, and repair or replace the damaged section. If the entire water service line is deteriorating, full water line replacement may be the better investment.
Why Professional Leak Detection Matters
Find the Leak Without Destroying Your Home
Cutting holes in walls and jackhammering slabs to search for a leak is expensive and destructive. Professional detection equipment lets us narrow the location before we open anything. Less damage to your home, faster repair, lower total cost.
Stop Water Damage Before It Escalates
FEMA estimates that just one inch of water in a home can cause more than $25,000 in damage. The sooner a hidden leak is found and stopped, the less damage it causes and the less the remediation costs.
Prevent Mold Before It Starts
Mold needs moisture and 24 to 48 hours to begin growing. A hidden leak provides exactly that. Finding and fixing the leak within that window prevents a water damage situation from becoming a mold remediation project.
One Company for Detection, Repair, and Remediation
If the leak has already caused water damage or mold, we handle the full scope in-house. Detection, plumbing repair, water extraction, drying, mold treatment, and rebuild. No coordinating between contractors.
24/7 Emergency Response
Water coming through the ceiling at midnight isn’t a problem that can wait until morning. We respond to emergency leak calls around the clock across all five counties. Call (443) 787-5995 and we’ll get a plumber to your property.
What to Expect From a Leak Detection Call
When you call for leak detection, we start by asking what you’re seeing: wet spots, high water bill, sounds, smells. This helps us arrive with the right equipment and a plan.
On-site, we use a combination of electronic listening equipment, thermal imaging, and visual inspection to narrow the leak location. For slab leaks, we may also use pressure testing to isolate which line is losing water. The goal is to pinpoint the exact location before we cut into anything.
Once the leak is located, we explain what we found, what caused it, and what the repair involves. You get upfront pricing before any work begins. Most leak repairs are completed the same visit. For slab leaks or situations where the damage is more extensive, we’ll walk you through the full scope including any demolition, rerouting, or remediation needed.
If the leak has been running long enough to cause water damage, we assess the affected area and can begin remediation the same day. We provide documentation for insurance claims including photos, moisture readings, and itemized repair invoices.
Hear It From Your Neighbors
Very Professional and gets the job done! Bailey Bros was recommended to me by a friend who is a general contractor. They came and were very transparent with everything that needed to be done. They were professional and courteous as they explained everything before and during the process. They had to dig a very deep trench to access my sewer line and they returned the following days to finish, re-seed and straw my yard. Thank you! I have peace-of-mind knowing the task was done right.
I was having problems with my toilet and was looking for a plumber. I called Bailey Bros. and spoke with Ray on the first call. He came to my home and fixed the issue. He was very professional and easy to deal with from the first conversation I had with him. He was great! I will only call Bailey Brothers for any plumbing issues I have in the future.
Had these guys install a hot water heater for me. I bought the heater and they were gracious enough to install it. They were friendly, responsive and the least expensive after a comprehensive search. Significantly less expensive. They were thorough and explained everything. Shawn (my tech) was charming. Someone you’d be happy to go out and have a drink with. They have a 5 star rating. They ran a little late, but for the savings and quality of work, it was well worth it. The basement was a little cleaner after their work than before they arrived. I highly recommend them.
Thank you Shawn and Mike! My water heater busted on a Saturday and they were able to install a new one within a few days! 🥰 you guys are awesome! It’s so much better than the old one from 1999! 🫠
Leak Detection Questions
How do you find a hidden water leak?
We use electronic listening equipment, thermal imaging, and pressure testing to locate leaks behind walls, under slabs, and underground. These methods let us pinpoint the source without tearing your home apart to search.
How much does leak detection cost in Maryland?
Cost depends on the type of leak and the complexity of the detection. We provide upfront pricing before any work begins. Financing is available through Wisetack for larger repairs.
Can you detect a leak under a concrete slab?
Yes. Slab leak detection is one of our most common services. We use electronic and pressure-based methods to locate the leak without unnecessary demolition.
What causes pinhole leaks in copper pipes?
Pinhole leaks in copper are typically caused by pitting corrosion from water chemistry, pH imbalance, or high mineral content. If pinhole leaks are appearing in multiple locations, the pipes may be corroding system-wide and repiping may be the better long-term solution.
Can you also fix the water damage from the leak?
Yes. We handle the full scope in-house: leak detection, plumbing repair, water extraction, structural drying, mold remediation, and rebuild. One company from detection through restoration.
Do you offer same-day leak repair?
Yes. Most leak repairs are completed the same visit as the detection. For more complex situations like slab leaks or water main leaks, we may need a second visit for excavation or rerouting, but we start as fast as possible.

We serve Harford County, Baltimore County, Baltimore City, Anne Arundel County, and Howard County, including Bel Air, Aberdeen, Towson, Dundalk, Baltimore, Annapolis, Glen Burnie, Columbia, and the I-95 corridor.
