Heritage Home Service is proud to offer professional leak detection services to homeowners across Maine. A hidden leak rarely announces itself clearly, it shows up as a higher water bill, a musty smell, or a damp spot that won’t go away. Our technicians use specialized equipment to find exactly where a leak is coming from, so the right repair can be made the first time, without guesswork or unnecessary digging.
What Homeowners Need to Know About Leak Detection
Leak detection is a diagnostic service. Rather than opening walls or digging up yardwork based on a guess, our technicians use non-invasive tools to pinpoint the exact source and location of a leak before any repair work begins. A typical leak detection visit includes:
- Acoustic listening equipment that detects the sound of water escaping from pressurized pipes, even behind walls or underground
- Thermal imaging to identify temperature differences caused by water intrusion or moisture buildup
- Pressure testing to isolate whether a leak is on the supply side, drain side, or an appliance connection
- Moisture meters to confirm the extent of water intrusion in walls, floors, or ceilings
- Video documentation where applicable, especially for slab or underground leaks
Because these methods are non-invasive, most leaks can be located without cutting into drywall or excavating your yard just to find the problem.
Why Leak Detection Comes Before Repair
Leaks can be deceptive. Water often travels along pipes, joists, or slab seams before surfacing somewhere far from the actual source. A repair attempted without proper detection can mean cutting into the wrong wall, digging in the wrong spot, or fixing a symptom while the real leak keeps causing damage.
Leak detection matters because it determines:
- Where the leak is actually located, which is often not where the water is visibly appearing
- What’s causing it — a pinhole leak, a corroded joint, a slab leak, or a failing appliance connection
- How extensive the repair needs to be — a localized fix versus a longer section of pipe
- Whether hidden damage like mold or structural wood rot has already begun
Skipping this step and guessing at a repair location often leads to repeat leaks, unnecessary demolition, and higher overall costs.
Common Signs You May Have a Hidden Leak
Maine homeowners often don’t realize they have a leak until it’s been active for weeks or months. Watch for:
- A noticeably higher water bill with no change in usage
- The sound of running water when all fixtures are off
- Damp, warm, or discolored spots on floors, walls, or ceilings
- A musty smell, especially in basements or crawl spaces
- Reduced water pressure throughout the home
- Wet or unusually green patches in the yard, particularly near buried supply lines
- Cracking or shifting in a slab foundation
Common Causes and Effects Behind Hidden Leaks
| Cause | Effect if Left Undetected |
| Pinhole leak in aging copper pipe | Slow water damage, mold growth over time |
| Corroded pipe joint | Gradual leak that worsens under pressure |
| Slab leak beneath a concrete foundation | Foundation damage, flooring damage, high water bills |
| Failing appliance supply line | Sudden leak, potential water damage to surrounding areas |
| Freeze damage from winter cold snaps | Cracked pipe, leak once the ice thaws |
A Homeowner Scenario: A Rising Water Bill in Portland
A homeowner in Portland, Maine noticed their water bill had nearly doubled over two months with no obvious explanation — no visible wet spots, no dripping faucets. Using acoustic detection equipment, our technician traced the sound to a pinhole leak in a supply line running beneath the concrete slab. Because the leak was pinpointed precisely, the repair required opening only a small section of flooring rather than a much larger excavation — saving significant time, mess, and cost.
What Happens After Your Leak Detection Service
Once we’ve located the source of your leak, Heritage Home Service will walk you through exactly what we found and recommend the appropriate next step:
- Leak Detection & Pipe Repair — for localized leaks, corroded joints, or pinhole leaks that can be repaired directly
- Drain Cleaning — if the issue is related to a clogged or damaged drain line rather than a supply line
- Fixture Installation — if the leak traces back to a failing fixture or connection that needs replacing rather than repairing
Because you’ll understand exactly where the leak is and why it happened, you can move forward with the repair confidently, without wondering if the real problem was ever actually found.
How to Know When You Need Professional Leak Detection
Consider scheduling a leak detection visit if:
- Your water bill has increased without a clear explanation
- You hear running water but can’t locate its source
- You notice water damage but aren’t sure where it’s originating
- You’re preparing to sell your home and want to rule out hidden plumbing issues
- A previous repair didn’t fully resolve a recurring leak
Frequently Asked Questions About Leak Detection

How long does a leak detection visit take?
Most inspections take one to two hours, depending on the size of the home and complexity of the plumbing system.

Yes. Slab leaks are one of the more common issues our acoustic and thermal equipment is specifically suited to locate.
