The Hidden Damage Problem
WHY HIDDEN LEAKS NEED PROFESSIONAL DETECTION
At Unclog Drain & Rooter, we know that a hidden water leak is one of the most damaging and expensive problems a Nairobi property can have – because most go undetected for months. A slow leak inside a wall or under a slab wastes thousands of litres of water, rotates your water bill upward every month, causes structural damage, promotes mould growth, and can destabilise foundations long before the first visible damp patch appears.
Stops Water Waste
A small hidden pipe leak can waste 50 to 200 litres per day depending on pressure. Unclog Drain & Rooter detection and same-day repair ends this immediately, cutting your water bill and protecting your water supply.
Prevents Structural Damage
Long-term water ingress from a hidden leak softens plaster, rots timber, corrodes steel reinforcement, and undermines concrete slabs. Early detection by Unclog Drain & Rooter avoids repair costs that escalate exponentially over time.
Eliminates Mould at Source
Mould caused by hidden leaks is a serious health hazard and is impossible to permanently eliminate without fixing the moisture source. Unclog Drain & Rooter locates and repairs the leak, stopping mould regrowth permanently.
Reduces Water Bills
Many Nairobi homeowners discover unexpectedly high water bills that cannot be explained by usage. Unclog Drain & Rooter leak detection typically locates the hidden waste within hours, providing immediate measurable savings.
Insurance Documentation
Insurance claims for water damage require documented evidence of the leak source. Unclog Drain & Rooter provides a written leak detection report with thermal images and acoustic data accepted by major Kenyan insurers.

How We Find It
LEAK DETECTION METHODS USED BY UNCLOG DRAIN & ROOTER
Unclog Drain & Rooter deploys the right detection technology for each leak scenario. No single method works for every situation – our engineers are trained in all four and select the optimal approach based on pipe type, construction, and leak suspected location.
Acoustic Leak Detection
Our primary method for pressurised supply pipes inside walls, under slabs, and underground. Specialist listening devices amplify the unique sound frequency of water escaping a pressurised pipe, allowing our Unclog Drain & Rooter engineers to pinpoint the leak location through solid concrete, masonry, and soil – with no drilling or breaking required until the exact spot is confirmed.
Primary Method
No Dig
Thermal Imaging (Infrared)
A thermal imaging camera detects temperature differences caused by water movement behind walls and under floors. Hot water pipe leaks create warm patches; cold water leaks create cool wet patches – both clearly visible on our thermal cameras. Unclog Drain & Rooter thermal imaging is especially effective for locating underfloor heating pipe leaks, bathroom waterproofing failures, and roof water ingress without disturbing any surfaces.
Visual Proof
No Contact
Tracer Gas Detection
For very small leaks that acoustic or thermal methods cannot locate, we introduce a safe, non-toxic hydrogen-nitrogen tracer gas mix into the pipe. The gas escapes through the leak point and rises to the surface where our detector captures it, identifying the precise leak location even at significant depth or in heavily built-up structures. Unclog Drain & Rooter tracer gas detection is the most sensitive method available for difficult-to-find micro-leaks.
Highest Precision
Difficult Leaks
Dye Testing and Pressure Testing
For pool shells, drainage systems, and roofs, non-toxic fluorescent dye is introduced to identify leak pathways visually. Pressure testing uses a gauge to confirm whether a pipe section is holding pressure – a drop indicates a leak. Unclog Drain & Rooter uses pressure testing both before detection to confirm a leak exists and after repair to certify that the fix is watertight before reinstating surfaces.

All Pipe Materials
PIPE TYPES UNCLOG DRAIN & ROOTER DETECTS AND REPAIRS
Unclog Drain & Rooter is equipped to detect leaks and carry out pipe repairs across all common pipe materials found in Nairobi residential, commercial, and industrial properties – regardless of age or installation type.
🔶 Copper
Copper Pipes
Common in Nairobi properties built before 2000. Copper corrodes at fittings and pin-hole leaks develop with age. We solder, braze, or replace sections using appropriate flux and copper or push-fit repair couplings.
⬜ uPVC
uPVC Supply Pipes
Widely used in modern Nairobi construction. Joint failure and UV degradation are the most common fault modes. We repair using solvent weld repair couplings or approved push-fit connectors for permanent sealing.
🟠 CPVC
CPVC Hot Water Pipes
Used for hot water supply lines in newer builds. CPVC is brittle with age and prone to stress cracking near fittings. We replace cracked sections with compatible CPVC or transition to modern flexible HDPE alternatives.
🟡 HDPE
HDPE Underground Pipes
The modern standard for underground supply and irrigation pipes. HDPE leaks are typically at electrofusion or compression joints. We repair with compatible HDPE fittings heat-fused or mechanically clamped for a permanent watertight joint.
🔩 Galvanised
Galvanised Steel Pipes
Found in older Nairobi properties and boiler rooms. Galvanised pipes corrode internally and eventually split. We carry out targeted section replacement using steel or transitional fittings, often recommending full re-pipe in severely corroded systems.
🔵 PPR
PPR Hot & Cold Pipes
Polypropylene random copolymer pipes are increasingly common in Nairobi new builds for both hot and cold supply. PPR joint failures require heat fusion for repair. Our engineers are trained in PPR heat welding for permanent, pressure-tested joints.
Recognise the Signs
8 SIGNS YOU HAVE A HIDDEN WATER LEAK
Unclog Drain & Rooter finds that most hidden leaks are missed for months because the signs are subtle at first. If you notice any of these warning signs, call us for a leak detection survey before the damage grows.
1
Unexplained High Water Bills
A sudden or gradual increase in your water bill with no change in usage is the most common indicator of a hidden pipe leak losing water continuously day and night.
2
Sound of Running Water
Hearing water running, dripping, or hissing when all taps and appliances are off strongly indicates an active leak somewhere inside the pipe system.
3
Damp Walls or Ceilings
Damp patches, peeling paint, or blistering plaster on walls or ceilings with no obvious external water source are caused by water escaping from a pipe behind the surface.
4
Mould in Unusual Locations
Mould appearing behind furniture, inside cupboards, or on walls far from bathrooms is almost always caused by moisture from a concealed pipe leak providing a continuous damp environment.
5
Low Water Pressure
A noticeable and unexplained drop in water pressure at all fixtures simultaneously indicates water is escaping from the supply pipe before it reaches the taps – a classic hidden main supply leak sign.
6
Warm or Wet Floor Patches
Warm spots on tiled or concrete floors in areas without underfloor heating indicate a hot water pipe leaking under the slab. Wet patches in the same area on a cold day confirm a cold water pipe leak.
7
Meter Running When Taps Are Off
Check your water meter with all taps off and no appliances running. If the meter dial or digital display is still moving, you have an active leak somewhere between the meter and your property.
8
Cracks Appearing in Walls
New cracks in internal plaster walls near pipe routes can indicate a pipe leak saturating and weakening the wall structure. This is particularly common with older clay-brick construction in Nairobi.

Got Questions?
LEAK DETECTION AND PIPE REPAIR – FREQUENTLY ASKED QUESTIONS
Honest answers to the questions Nairobi property owners ask Unclog Drain & Rooter before booking a leak detection survey.
How much does leak detection cost in Nairobi?
Unclog Drain & Rooter acoustic leak detection surveys start from KES 8,500 for a single-zone residential supply pipe survey. Our most popular package – detection plus same-day pipe repair – starts from KES 22,500. Full commercial multi-zone surveys with thermal imaging and tracer gas start from KES 38,000. All pricing is flat-rate and confirmed before the survey begins with no hidden additions.
Can you find a water leak without breaking my walls?
Yes. Unclog Drain & Rooter uses acoustic listening devices, thermal imaging cameras, and tracer gas to locate your leak through walls, floors, and underground without any breaking, drilling, or excavation. We only open the surface at the single confirmed leak point – keeping access damage to the absolute minimum. In most cases, the opening is no larger than a single tile or brick.
How do I know if I have a hidden water leak?
The most reliable self-check is the meter test: turn off all taps and water-using appliances, then check your water meter. If the dial or display is still moving, you have an active leak. Other signs include an unexplained increase in your water bill, damp or stained walls with no visible cause, the sound of running water when everything is off, low water pressure, warm patches on floors above hot water pipes, and mould appearing in unexpected locations.
How long does leak detection and repair take?
A standard residential acoustic detection survey takes 1 to 2 hours. Thermal imaging and multi-zone surveys take 2 to 4 hours. Once the leak is confirmed and located, most standard pipe repairs are completed the same day within an additional 1 to 3 hours. You receive your written report and pressure test results before the Unclog Drain & Rooter team leaves your property.
What is acoustic leak detection?
Acoustic leak detection uses specialist electronic listening equipment to amplify the sound of water escaping from a pressurised pipe. Water leaking through even a small crack produces a distinctive frequency that our sensors pick up through solid walls, concrete slabs, tiles, and soil. By comparing signal intensity at different points, our Unclog Drain & Rooter engineers triangulate the exact leak location to within approximately 10 centimetres – with no surface damage required until the repair.
Do you repair the pipe after finding the leak?
Yes – Unclog Drain & Rooter is a complete detect-and-repair service. Our most popular package combines detection and same-day repair in a single visit. We carry all common pipe repair materials and fittings for copper, uPVC, CPVC, HDPE, and PPR pipes. After repair, we carry out a pressure test to confirm the leak is fully resolved, then reinstate the access opening as neatly as possible. Full surface reinstatement (tiling, plastering) can be arranged as an additional service if required.
Will the leak detection report be accepted by my insurance company?
Yes. Unclog Drain & Rooter leak detection reports include thermal imaging photographs, acoustic data records, a written description of findings, the confirmed leak location, and post-repair pressure test results. This format meets the documentation requirements of major Kenyan insurers for water damage claims. If your insurer has specific requirements, let us know when booking and we will ensure the report format matches their submission criteria.
Can you detect leaks in swimming pool pipes?
Yes. Unclog Drain & Rooter offers specialist pool and irrigation leak detection using non-toxic fluorescent dye testing, tracer gas, and pressure testing on the return and supply lines. We can identify leaks in the pool shell, underground pipework, pump connections, and filtration systems. If your pool is losing water consistently and evaporation does not account for it, a detection survey will identify the source accurately and allow targeted repair without draining the entire pool.
