About Us
Chelsea's Hidden Leak Specialists
Non-invasive leak detection means finding the exact source of a water leak without tearing your home apart. Acoustic sensors hear pressurized water escaping through pinholes. Thermal imaging cameras see the temperature signature of moisture behind walls and under floors. Tracer gas testing traces an inert gas to the precise point of escape. Together, these methods pinpoint leaks other plumbers can only guess at.
We are Chelsea Leak Detection, and for 13 years this is all we have focused on: hidden water leaks in Chelsea homes and businesses. High water bills with no visible cause. Damp patches spreading across a ceiling. Warm spots on a slab floor. Mysterious meter movement when every tap is off. These are the problems our equipment was built to solve — quickly, cleanly, and with minimal disruption to your property.
Because we locate before anyone digs, repairs start at the right spot the first time. That saves drywall, flooring, landscaping — and money. , or call now and describe what you are seeing. We will tell you honestly whether you need us.
During a typical visit, we start with a walkthrough of your symptoms, then sweep the suspect areas with acoustic and thermal equipment, and finish with a written summary of findings. Most residential surveys wrap up in under two hours — and you will know exactly what was found before we leave.

Our Services
Complete Leak Detection Services
Every service below uses the same principle: locate first, dig second. From slab leaks to pool leaks, our acoustic, thermal, and tracer gas equipment finds the exact source of hidden water loss in Chelsea homes and businesses — so repairs are surgical, not exploratory. Browse all 21 services or call now for the urgent ones.
Water Leak Detection
Our core specialty: acoustic sensors, thermal imaging, and tracer gas find hidden leaks behind walls, under floors, and underground — accurately, non-invasively, and usually in a single visit.
High-Bill Leak
Water bill suddenly high with no visible leak? We check the meter, the service line, and your home to find the hidden loss — then show you exactly where it is.
Buried Line Leak
Soggy lawn, sinking soil, or water surfacing where it should not can mean a buried pipe leak. Ground microphones and tracer gas locate it without tearing up your yard.
Wall Leak
Damp patches, bubbling paint, or a musty smell inside a wall signal a hidden pipe leak. Thermal imaging maps the moisture so only the damaged section is opened.
Ceiling Leak
A spreading stain on the ceiling needs a fast, accurate answer: active leak or old damage? Moisture meters and thermal scans tell us — and trace it to the source above.
Water Service Line Leak
The line from the street to your home can leak underground for months. We confirm the loss at the meter, then pinpoint the break — so excavation happens in exactly one spot.
Commercial Leak Detection
Hidden leaks shut down businesses. We survey offices, retail, and restaurants with minimal disruption — after hours if needed — and deliver reports your insurer accepts.
How It Works
Our Simple 4 Step Process
No guesswork, no exploratory demolition. Every visit follows the same disciplined process, refined over 13 years of leak hunting in Chelsea.
01
Call & Describe
Call any time, day or night. Tell us what you see, hear, or smell — stains, sounds, bill spikes — and we dispatch with the right equipment.
02
Non-Invasive Survey
We sweep the suspect area with acoustic sensors and thermal imaging first — listening and seeing through walls, floors, and soil without opening anything.
03
Pinpoint & Report
Tracer gas or pressure testing confirms the exact point of failure. You get clear findings — photos, readings, and a written summary for your plumber or insurer.
04
Targeted Next Steps
With the leak marked to the inch, repair means one small opening — not a renovation. We guide you on the fix and how to prevent the next one.
Why Choose Us
The Leak Detection Difference
Most plumbers find leaks by opening walls until they get lucky. We do the opposite: our instruments locate the leak first, so the wall gets opened once — at exactly the right spot. That single difference is why Chelsea homeowners call us after one or two plumbers have already missed the problem.
Thirteen years of nothing but leak detection has taught us where Chelsea's homes hide their failures: aging copper in triple-deckers, slab penetrations in post-war ranches, corroded service lines under established lawns. We bring acoustic listening gear, thermal cameras, tracer gas rigs, and moisture mapping to every job — the same toolkit, whether the leak is behind a bathroom tile or under a commercial slab.
Chelsea's building stock keeps us busy in specific ways: century-old multi-family homes with original supply lines, mid-century slabs with aging copper, and commercial blocks where a small leak can idle a business for days. Because we work only in this city, pattern recognition is part of the toolkit — we often know where to listen first.

Before & After
Find It First, Fix It Once
A water-damaged wall is a symptom; the leak is the disease. Drag the slider to see the difference between damage left to spread and a wall restored after the source was pinpointed. The "before" side is what happens when a leak hides for months — paint bubbles, plaster softens, and mold gets a foothold.
Our job is to make sure the "after" side only ever needs one repair. Thermal imaging shows us the full moisture footprint behind the surface, so remediation crews know exactly how far the damage reaches — no more, no less. When the source is found early, most of our customers never reach the "before" stage at all.
If you are looking at a stain like the one on the left, do not wait for it to grow. Call (617) 380-4912 and we will trace it to its source, usually in a single visit.

Proudly Serving All Of Chelsea

Chelsea packs a lot of plumbing history into a small footprint: older multi-family homes near the water, post-war housing on the hills, and busy commercial corridors around Bellingham and Chelsea Squares. Aging supply lines, freeze-thaw winters, and nor'easter-driven rain keep hidden leaks common here — which is exactly why a local detection specialist, rather than a generalist, makes the difference.

FAQ
Got Questions? We've Got Answers!
Straight answers about hidden leaks, our methods, and what happens when you call.
The classic signs are a water bill that climbs for no clear reason, a meter that moves when every tap is off, damp patches or bubbling paint, a musty smell with no visible water, warm spots on the floor, or the faint sound of running water inside walls. Any one of these is worth a professional check — hidden leaks only get more expensive with time.
We answer 24 hours a day, 7 days a week, and our emergency technicians reach anywhere in Chelsea in 30–45 minutes. When water is actively spreading — a burst pipe, a flooding basement, a ceiling dripping onto the floor — call (617) 380-4912 now and we dispatch immediately.
No. Our whole approach is non-invasive: acoustic sensors listen for the leak, thermal cameras see moisture through surfaces, and tracer gas confirms the exact point — all without opening anything. We cut no holes until we are certain of the spot, which usually means a single small opening instead of exploratory demolition.
Every situation is different — a straightforward wall leak and a buried service line need different equipment and time. What we promise is clear pricing upfront with no hidden call-out fees, confirmed before any work begins. Call (617) 380-4912, describe what you are seeing, and we will give you a straight answer.
Yes — we serve all of Chelsea, MA 02150, including Downtown, Admirals Hill, Mill Hill, Addison-Orange, Prattville, Soldiers' Home, Chelsea Square, and Bellingham Square. Wherever you are in the city, emergency arrival is 30–45 minutes.
Very often, yes. Standard plumbing tools cannot see inside walls or under slabs, which is why we invested in specialist detection equipment — acoustic correlators, thermal imaging, tracer gas, and moisture mapping. Many of our customers call us after one or two previous visits failed to find the source.
If water is actively flowing, shut off your main water valve if you can do so safely, move valuables away from the wet area, and avoid touching anything electrical near the water. Do not tear open walls or floors — note where you see, hear, or smell the problem and let our equipment do the locating when we arrive.
Yes. Every visit ends with clear written findings — what we found, where, and how we confirmed it — with photos and moisture readings where relevant. Our reports are routinely accepted by home insurance adjusters and give your repair professional an exact starting point.
Yes. We are available 24/7 — nights, weekends, and holidays. If you are dealing with an active leak, call (617) 380-4912 now for a 30–45 minute emergency arrival anywhere in Chelsea. For non-urgent concerns, call any time and we will schedule a visit that suits you.
Our specialty is finding the leak with pinpoint accuracy. Repair work is performed by the independent local professional you are connected with through our referral service — and because we hand them the exact location, their repair starts at the right spot on the first try.
