We locate hidden water leaks in Crawley properties using thermal imaging and acoustic technology - no digging required. With 15 years experience and a 12 month warranty, we've helped hundreds of local homeowners stop leaks before they cause serious damage.
Sarah Mitchell noticed something odd at her home on Hazelwick Avenue in Maidenbower last November. Her water meter was spinning constantly, even when every tap was off and nobody was home.
"At first, I thought it was just a faulty meter," Sarah told us when she called 0800 916 8602 on a Tuesday morning. "But then Southern Water confirmed the meter was fine. That's when I panicked - I had a hidden leak somewhere."
Her quarterly water bill had jumped from around £85 to over £340. Three plumbers had already visited, checking every visible pipe and bathroom fitting. Nobody could find the problem. One suggested digging up her entire front garden to check the main supply pipe - a quote of £4,500.
We arrived at Sarah's property that same afternoon. Our thermal imaging camera revealed a cold patch under her dining room floor within twenty minutes. The temperature difference was subtle - just 2.3 degrees - but our experienced eye spotted it immediately.
Using acoustic listening equipment, we pinpointed the exact location. A central heating pipe buried in the concrete floor screed had developed a pinhole leak. Water had been escaping into the sub-floor for months, probably since the previous winter's freeze.
"I couldn't believe how accurate they were," Sarah said. "They marked a 30cm square on my floor. When the plumber cut into it, the leak was exactly where they said."
The repair took three hours and cost £680 including floor reinstatement. Compare that to the £4,500 garden excavation that wouldn't have found anything. Sarah's water bill returned to normal the following quarter.
The detection itself cost £395 and came with our 12 month warranty. Sarah's case is typical of what we see across Crawley - homeowners being quoted thousands for excavation when precision technology can locate the problem in hours, not weeks.
"The 15 years experience really showed," Sarah added. "They'd obviously seen this type of leak hundreds of times before. I'd recommend calling 0800 916 8602 to anyone with unexplained water issues."
What made Sarah's case particularly interesting was the Weald Clay soil common in Maidenbower. This clay expands and contracts with seasonal moisture changes, putting stress on underground pipes. It's why we see higher leak rates in this part of Crawley compared to areas on sandstone bedrock.
We've been finding hidden water leaks across West Sussex for 15 years. Every day, we help Crawley homeowners avoid the nightmare of unnecessary excavation and the thousands it costs.
Our technology detects leaks through walls, floors, and underground without any digging. Thermal imaging cameras see temperature differences invisible to the human eye. Acoustic equipment hears water escaping from pipes, even through concrete.
The combination gives us pinpoint accuracy. We typically locate leaks to within 30cm - sometimes closer. That precision means minimal disruption and maximum cost savings for you.
Every leak detection survey includes our 12 month warranty. If we identify a leak location and it proves inaccurate, we return free of charge to reinvestigate. In 15 years, this has been necessary less than 3% of the time.
We understand Crawley's unique challenges. The mix of Victorian properties in Ifield, post-war estates in Langley Green, and modern developments in Forge Wood all present different leak patterns. Clay soil in the southern neighborhoods, flight path noise near Gatwick, and the area's hard water all affect how we approach each job.
Same-day service is available when you call 0800 916 8602 before 2pm. Emergency appointments for active leaks causing immediate damage can often be arranged within hours.
Our written reports include thermal photographs, marked floor plans, and repair recommendations. These documents support insurance claims and give contractors exact guidance for fixes.

Crawley sits predominantly on Weald Clay, particularly in the southern neighborhoods like Furnace Green, Tilgate, and Southgate. This clay soil is notorious for seasonal movement.
During wet winters, the clay absorbs water and expands. Summer drought causes it to contract and crack. This constant cycle stresses underground pipes, creating weak points that develop into leaks over 10-15 years.
Marcus Thompson in Furnace Green discovered this the hard way. His supply pipe failed where it entered the property - exactly where clay movement creates maximum stress. Our acoustic detection located the leak under his driveway, saving him from excavating the entire front garden.
Properties built on Weald Clay experience approximately 40% more underground leaks than those on the sandstone found in northern Crawley. If your home is in Tilgate, Furnace Green, or Southgate, this ground condition makes leak detection particularly important.
Crawley's proximity to Gatwick means properties in Three Bridges, Lowfield Heath, and Tinsley Green experience constant low-level vibration from aircraft movements. While this doesn't cause leaks directly, it accelerates wear on pipe joints and fittings.
Janet Davies on Haslett Avenue East called us about a leak in her heating system. The property sits directly under the main approach path. We found multiple failing compression joints - the constant vibration had gradually loosened them over twenty years.
"I never connected the aircraft noise with plumbing problems," Janet said. "But when they explained it, everything made sense. The 15 years experience really showed."
Crawley receives hard water from the chalk aquifers. While this isn't a health issue, the dissolved minerals cause internal pipe corrosion over decades.
Copper pipes develop pinhole leaks after 40-50 years as limescale creates galvanic cells on the inner surface. We see this constantly in Langley Green and Northgate's 1960s housing stock.
David Wilson's property on Northgate Avenue had three separate pinhole leaks in six months. Our thermal imaging found them all without lifting a single floorboard. Each repair cost around £300 - total £900 compared to £4,000+ for speculative floor removal.
Ifield and Old Town contain Crawley's oldest properties. Many still have original lead supply pipes installed over 100 years ago. These degrade slowly, developing leaks as the metal work-hardens and cracks.
Patricia Richards on Ifield Avenue discovered her lead pipe was leaking 200 liters daily into the front garden. The leak had created a subsidence cavity under her bay window - repairs would have cost £12,000 if left undetected.
Our acoustic equipment traced the leak location precisely. Replacing just the failed section cost £1,800, with foundation work adding another £2,400. Still £8,000 less than if we'd found it six months later.
Newer areas like Forge Wood and Kilnmead use plastic push-fit plumbing. While generally reliable, these connections can fail if not installed perfectly or if subjected to ground movement.
Robert Zhang's property in Forge Wood developed a leak just four years after construction. A push-fit connection under the floor screed had gradually worked loose. Our thermal imaging found it immediately - repair cost £520 with minimal floor disturbance.
"The builder wanted to lift the entire ground floor," Robert explained. "That would've cost £6,000. Calling 0800 916 8602 saved me thousands."
Our thermal cameras detect temperature variations as small as 0.1°C. When water leaks from pipes, it creates cold spots (for water supply leaks) or warm spots (for heating system leaks) that show up clearly on screen.
The technology works through walls, floors, and ceilings. We can scan an entire three-bedroom home in 90 minutes, identifying every moisture area without lifting a single floorboard.
Christopher Bailey in Broadfield had mysterious damp patches in two rooms. Previous investigations found nothing. Our thermal scan revealed a concealed bathroom pipe leak behind tiles - one 30-minute survey solved a six-month mystery.
"The thermal images were incredible," Christopher said. "You could see exactly where the cold water was spreading through the wall. The 12 month warranty gave me confidence they'd got it right."
Thermal imaging is particularly effective for:
Water escaping from pressurized pipes creates distinctive sound frequencies. Our sensitive microphones detect these sounds through concrete, tarmac, and soil - even when inaudible to human ears.
We place sensors at multiple points along suspected pipe runs. Digital processing triangulates the exact leak position by comparing sound arrival times at each sensor. Accuracy typically reaches 30cm, sometimes better.
Angela Foster's property on Goffs Park Road had an underground leak somewhere between the meter and house - a 15-meter stretch under paving and garden. Our acoustic equipment pinpointed it to a 50cm section. Total excavation: one small hole. Cost: £890. Alternative: dig up entire run at £4,500+.
Acoustic detection works well for:
The technology isn't affected by Gatwick aircraft noise. We use frequency filters that focus on water leak sounds (100-3000 Hz) while blocking out jet engines and traffic.
Before using thermal or acoustic equipment, we often conduct pressure tests. These confirm leak presence and isolate which section of pipework has the problem.
We close isolation valves to separate your plumbing into sections - typically ground floor, first floor, heating system, and external supply. Each section is pressurized with air or water. Pressure drops indicate leaks.
This approach saved Michael Chen in Langley Green substantial money. He'd assumed multiple leaks across his property. Pressure testing revealed just one leak in the ground floor heating circuit. One repair job instead of three - £650 instead of £2,000+.
"The systematic approach impressed me," Michael said. "They didn't just start searching randomly. Everything was logical and methodical - that's the 15 years experience showing."
Traditional leak detection meant breaking open walls and floors until you found the problem. Costs escalated quickly - £3,000 to £12,000 wasn't unusual.
Our technology locates leaks precisely before any excavation. You pay for detection (from £195) then targeted repairs. Total costs typically £500-£1,500. That's 70-90% savings with our 12 month warranty for peace of mind.

Your Saving: 70-90% with 12 Month Warranty
James Norton moved into his property on Grattons Drive in September. By December, his heating system pressure kept dropping. Every few days, he'd top it up using the filling loop. The boiler engineer couldn't find any visible leaks.
"I was topping up the pressure three times a week," James explained. "The engineer said it must be evaporation, but I knew that wasn't right. Water doesn't just disappear."
He called us in January after his neighbor recommended our service. Our thermal imaging revealed a cold patch under the living room floor within 40 minutes. A heating pipe buried in the screed had developed a pinhole leak.
The leak had been running since October - probably started during the system's first winter operation. Water was slowly seeping into the concrete sub-floor, creating a growing moisture problem.
We marked the exact location. James's plumber cut a 40cm square of laminate and concrete, found the leak precisely where indicated, and replaced the pipe section. Total repair cost: £720 including floor reinstatement.
"The 15 years experience was obvious," James said. "They knew exactly what they were looking for. The 12 month warranty meant I could get the repair done with confidence. Best £395 I've spent - saved me thousands in floor damage."
What made James's case interesting was the Weald Clay ground movement in Pound Hill. The seasonal contraction had stressed the pipe enough to create a weak spot. Without our detection, the leak would have continued for months, potentially causing subsidence.
Emma Rodriguez runs a café on Haslett Avenue East. Last March, her water bill jumped from £180 to £620 in one quarter. Then customers started complaining about wet patches in the front seating area.
"I thought it was rainwater at first," Emma told us. "But the patches appeared even during dry weather. Then I got the massive bill and realized something was seriously wrong."
She called 0800 916 8602 on a Friday morning. We arrived that afternoon - business interruption was costing her £400 per day in lost trade and reputation damage.
Our acoustic equipment traced the leak to her supply pipe under the pavement outside. The pipe had corroded where it joined the water main - a common failure point in Three Bridges due to the clay soil movement.
The leak was outside her property boundary, making it Southern Water's responsibility. Our detailed report with acoustic findings convinced them to conduct emergency repairs that weekend instead of their usual 3-4 week wait.
"The detection cost me £495, but having that professional report probably saved me a month of closure," Emma said. "They knew exactly how to document everything for the water company. That's worth the 15 years experience right there."
Her café reopened Monday morning. The water bill returned to normal the following quarter - she'd been wasting 400 liters daily for at least four months. Our 12 month warranty meant if any further issues arose from the same pipe section, we'd reinvestigate at no charge.
Aircraft noise doesn't interfere with our acoustic leak detection equipment. We use specialized frequency filters that focus on water leak sounds (100-3000 Hz) while blocking out jet engine noise (typically above 4000 Hz).
In areas like Three Bridges and Lowfield Heath directly under flight paths, we've successfully detected hundreds of leaks despite aircraft overhead. The 15 years experience means we know how to work in these conditions.
The Weald Clay subsoil common in southern Crawley causes significant ground movement during seasonal changes. Wet winters make it expand; dry summers make it contract and crack. This constant shifting stresses underground pipes.
Properties in Pound Hill, Maidenbower, Furnace Green, and Tilgate built on this clay experience approximately 40% more underground leaks than homes on sandstone areas in northern Crawley. Our thermal imaging can detect these leaks before major subsidence damage occurs.
Most residential surveys complete within 2-3 hours. Simple single-room investigations take around 1 hour. Comprehensive whole-property thermal scans may extend to 4 hours for larger homes.
We provide immediate verbal findings before leaving. Written reports with thermal photographs follow within 48 hours. Same-day service is available when you call 0800 916 8602 before 2pm, with our 12 month warranty covering all detection accuracy.
Absolutely. Ifield and Old Town's Victorian homes present unique challenges with original lead pipes, solid walls, and aging infrastructure. Our thermal imaging works particularly well here because it doesn't require access to pipes.
We can scan through original plasterwork without any damage. Many Victorian properties in Ifield Avenue and around St Margaret's Church have lead supply pipes over 100 years old. Our acoustic equipment traces leaks in these pipes with excellent accuracy, backed by 15 years experience with period properties.
Our warranty covers detection accuracy. If we identify a leak location and subsequent excavation proves it incorrect, we return free of charge to reinvestigate. This has been necessary less than 3% of the time in 15 years.
The warranty also covers our written reports and marked locations. If contractors working from our instructions question the findings, we'll attend site to confirm our detection at no additional cost. This gives you complete confidence when commissioning expensive repairs.
Yes. Our detailed reports include all information insurers require - thermal photographs, precise leak locations, cause analysis, and repair recommendations. We've worked with every major insurance company over 15 years.
Many Crawley customers have successfully claimed for both our detection service and subsequent repairs. The key is calling us quickly - most insurers want leaks detected within 30 days of discovery. Call 0800 916 8602 as soon as you suspect a problem to protect your insurance position.
