Leak Detection in Ware
Find the leak before anybody lifts a floor
We trace leaks with thermal imaging, acoustic equipment, tracer gas and moisture meters, so the only part of your floor that comes up is the part with the leak underneath it.
Vantage Plumbing and Heating covers Ware and SG12 from Stevenage, eleven miles west on the A602. Gas Safe registered, reg. 956889. Twelve months on our workmanship, a genuine 24/7 line, and a written report you can send to your insurer.
Why leaks behave differently on Ware's chalk
Ware sits on chalk, and it sits on it deeply. Scott’s Grotto extends more than twenty metres into the chalk hillside beneath the town, which is a useful way of understanding what is under your garden.
That geology changes how a leak presents itself, and it is the single most important thing to understand before you start looking.
On heavy clay, an underground leak tends to make itself obvious. Water cannot get away, so it tracks along the pipe, saturates the ground and eventually shows up as a soft patch, a green stripe across a dry lawn or water coming up through a driveway joint.
On chalk it frequently does none of that. Water percolates away into the ground and never surfaces. Which means a leak on the supply pipe in Ware can run for months, sometimes years, with no visible sign whatsoever, and the only symptom is a water bill that has crept upwards or a meter that keeps counting when the house is empty. We are called to properties around SG12 every year where the first evidence of a substantial leak was a bill, not a puddle.
There is a second local factor working the other way. The River Lea runs through the town and forms part of the Lee Navigation, and the New River, cut in the early 1600s to take water down to London, has its historic source point here and runs through the streets south of the Lea. Along that corridor the water table is close to the surface, and the Environment Agency operates a flood warning target area for the River Lee at Hertford and Ware.
That matters because in low lying properties near the water, damp in a floor or at the base of a wall is not automatically a plumbing leak. Sometimes it is groundwater. We test rather than assume, and if the damp is coming from outside the plumbing system we will say so rather than replace a pipe that is not broken.
The first signs, in the order people usually notice them
The water bill goes up with no change in the household. This is the most common way an underground leak in Ware announces itself.
The meter turns with everything off. Turn every tap off, do not flush anything, and watch the meter for half an hour. Movement means water is going somewhere.
The boiler pressure keeps dropping. If you are topping the system up more than a couple of times a year, there is a leak on the heating circuit, and if there are no wet radiator valves it is usually under a floor.
A patch of floor is warm. On a heating leak under screed, warmth in one area is often the earliest sign and the easiest to miss.
A musty smell, a damp skirting or peeling paint at low level, with nothing visible above it.
Unexplained noise. A faint hiss or rush in the pipework at night, when the house is quiet, is the sound of water escaping under pressure.
How we actually find it
Thermal imaging. A calibrated camera reads surface temperature differences. It is the fastest way to trace a hot water or heating leak under screed, and it maps out underfloor heating circuits without lifting a single tile.
Acoustic detection and correlation. Escaping water under pressure makes a specific noise. Ground microphones and correlating equipment let us listen along a run and narrow the position of a leak on a buried supply pipe, often to within a small area. It is far better on metal pipe than on modern plastic, which carries sound poorly, so on a newer run tracer gas does the work.
Tracer gas. Where a pipe is empty, cold or too deep to hear, we introduce a hydrogen and nitrogen tracer mix, harmless and non flammable at the concentration used, and detect where it emerges. It is the tool that solves the leaks nothing else will find.
Moisture meters and hygrometers. Used to map how far moisture has travelled and, importantly, to distinguish a plumbing leak from rising or penetrating damp. On riverside properties in Ware that distinction earns its keep.
Pressure testing and isolation. Sometimes the fastest route is methodical: isolate sections, pressure test each one, and eliminate.
The properties in Ware where leaks hide best
The historic core: High Street, Church Street, Crib Street, West Street, East Street and Kibes Lane. The densest concentration of historic buildings in the town, spanning the sixteenth to the nineteenth century, with around a third of the listed stock dating from the seventeenth. These buildings have solid floors, thick walls, boxed in pipe runs and centuries of alterations layered over each other. There is no drawing showing where anything is. Non invasive detection is not a nicety here, it is the only sensible approach, because opening up historic fabric speculatively is both destructive and, on a listed building, potentially a consent issue with East Herts Council.
Priory Street, Watton Road, Gladstone Road and around Buryfield. Mixed residential streets west of the old centre. The common find here is a leak on the private supply pipe between the boundary and the house, on runs that have never been renewed. Older stock in this area can still have lead or old iron underground, and on chalk that leak will not surface. We trace it, tell you exactly where it is, and can then replace the run rather than digging the whole garden.
Extensions, conversions and anything with underfloor heating. Underfloor heating in screed is where we do a great deal of our work. A pinhole in a circuit, or worse, a screw driven through a pipe during a later floor covering job, causes constant pressure loss and no visible water at all. Thermal imaging maps the circuits, finds the anomaly, and gives us one small area to open up instead of a whole room.
Wet rooms and shower trays. A significant proportion of what gets reported as a plumbing leak is a failure of sealing rather than a failure of pipework. A tanking membrane that was never dressed properly into the tray, a failed seal at the tray upstand, a cracked grout line letting water behind the tile. It looks identical from the ceiling below. We test the difference by isolating the supply and running the shower, and we tell you which it is before anybody starts pulling tiles off.
Outlying properties towards Wareside, Thundridge, Chapmore End and Sacombe. Long private supply runs across fields and verges, sometimes several hundred metres of it, sometimes in pipe nobody living has seen. These are exactly the leaks that never surface on chalk. Acoustic correlation and tracer gas do the work here.
The bit of the pipe that is yours, and the bit that is not
This catches people out constantly, so it is worth being clear.
Affinity Water supplies the mains water to Ware. Its responsibility runs to the boundary stopcock, generally in the pavement or verge outside your property under a small lid. From that point to the house, the private supply pipe is yours. If a leak is on that section, it is your repair and your cost, and on chalk you may never have known about it if the bill had not moved.
Wastewater in Ware is Thames Water’s responsibility, which is a separate matter from your supply, and Thames Water’s Rye Meads works on Rye Road treats the sewage for this area.
Insurance, trace and access
Many home buildings policies include trace and access cover, which is the work of finding a leak and getting to it, separately from repairing the damage. Policies differ and we are not going to tell you what yours says. Check your policy schedule for trace and access cover and put the question to your insurer before you agree to the work.
What we do is produce the report your insurer asks for, setting out the symptoms, the methods used, what was found and where, with thermal images or readings where relevant.
If you have already had somebody lift half a floor on a guess, we can still help. It just costs more than it needed to.

What it costs
Detection is priced as a job, based on the property and what we expect the investigation to involve, and you are told that price before we attend. We do not charge by the hour and let it run.
Repair is quoted separately, once we know what we are dealing with, because a compression fitting under a floorboard and a full supply pipe replacement across a driveway are not the same job. If the leak turns out to be a sealing failure in a shower rather than pipework, we say so.
Related work in Ware
Once the leak is found, the repair usually sits with us too: supply pipe replacement, pipework under floors, radiator and valve work, cylinder and unvented cylinder repairs, and boiler side work under our Gas Safe registration. We also run drainage CCTV surveys, which is the right tool when what looked like a supply leak turns out to be a broken drain instead. One team, one report, one person answering the phone about it.

Frequently Asked Questions
Will you have to dig up my garden or lift my floor?
Not to find the leak. None of thermal imaging, acoustic tracing or tracer gas is invasive. We only open up once we know where the leak is, and then only that spot.
My water bill has jumped but there is nothing wet anywhere. Is that possible?
Very much so, and it is common in Ware. The chalk beneath the town lets escaping water percolate away instead of surfacing, so an underground leak can run for a long time with no visible sign at all.
Who pays for a leak on the pipe from the road to my house?
You do. Affinity Water is responsible up to the boundary stopcock, and the private supply pipe from there into the property is the homeowner’s.
My boiler pressure keeps dropping. Is that a leak?
Usually yes. If nothing is wet at the radiator valves or the boiler itself, it is generally a leak in pipework under a floor or in an underfloor heating circuit. Thermal imaging finds those quickly.
Can you tell whether my damp is a leak or groundwater?
Yes, and near the River Lea and the New River it is a question worth asking. Moisture mapping plus isolation testing tells us whether the plumbing is involved before anybody starts replacing pipe.
Will my insurance pay for the detection work?
The terms of your policy are between you and your insurer, so read your schedule and ring them before instructing anybody. Look for trace and access. The written report they ask for is provided by us.
