Many homeowners will overlook a small leak, thinking it’s only small so it can be put off for now. They wait for the right time, but while you’re waiting, that leak is causing significant damage beyond your view. Water leaks can spread like a virus within your walls or cabinetry, under your floor, or in your ceiling.
The best way to minimise the damage is to catch and address them early. Leak detection specialists use thermal imaging equipment to see what the naked eye cannot, detecting hidden moisture within structures.
Today, we’ll explore why you should never ignore or put off a small leak and how thermal water leak detection can help minimise damage.
Why a Small Leak Isn’t a Small Problem
Small leaks may seem like a small problem that can wait until you have free time or more budget available, but the truth is, small leaks are almost never a small problem. And waiting will almost always result in extensive damage and more expensive and time consuming fixes.
A dripping tap, pipe, or fixture may seem like a minor inconvenience, but behind the scenes, that water can travel long distances through your structures, damaging everything in its path and promoting mould growth. This means that when you finally get around to dealing with it, you’ll likely be facing extensive property repairs rather than a potentially simple leak fix.
How and Where Water Travels
Water is great at finding paths through structures, allowing it to travel long distances from the original origin point. Water will often flow along or through structural elements, rather than simply dripping directly down. Our leak detection specialists have often found puddles, moisture or water damage metres from the original leaking fixture.
Through Wall Cavities
Once water enters the wall cavity it can travel along walls, framing and sheeting. This means that when a shower recess leaks, the water can travel throughout the bathroom and even into adjacent rooms through the walls. This allows damage to spread quickly.
Timber and plasterboard is absorbant, so it can absorb some of the water as it passes through, causing it to swell and rot. Moreover, constant moisture in dark wall cavities can promote the growth of mould and mildew, presenting serious health and safety hazards.
Along Flooring and Subfloor
Water can travel along skirting boards, tiles, grout, or floorboards, damaging anything in its path and finding gaps to seep through to and pool on the subfloor. Certain flooring materials, such as laminate, timber, and engineered wood can absorb moisture quickly, causing warping, swelling, delamination, rotting, glue dissolution, and mould growth.
Into Cabinetry and Joinery
Leak under sinks can damage cabinetry quickly, as well as anything else in the cupboard at the time. Even a slow dripping under-sink pipe can expel a large amount of water over time, causing puddling inside your cabinets.
Cabinets and joinery can wick moisture into the structures much like wall structures and flooring, causing materials to become soft, rotten, or swollen. The dark, moist environment inside a cabinet with a leak is also the perfect environment for mould to thrive.
Through Ceiling Spaces
Roof leaks or leaking pipes in ceiling spaces can expel water throughout your building. Water can travel from the top down, following ceiling structures or pipes and finding gaps to flow into wall cavities. It can also pool in the ceiling until it seeps through and causes significant damage and mould growth.
What Thermal Imaging Reveals
Thermal Imaging is one of the best methods for locating moisture that is invisible to the naked eye. Thermal imaging cameras work by detecting differences in surface temperature caused by moisture. Moisture causes the materials it contacts to retain or release heat differently than dry materials, creating a distinct thermal signature the camera picks up. These wet spots, also known as hot spots, show up as bright red or orange on the cameras, allowing technicians to visualise the extent of the moisture spread and damage.
These thermal signatures are visible long before surface damage or mould growth, supporting early water leak detection and targeted repairs. Experienced technicians can use this technology to trace moisture back to an origin point, if the source of the leak is unknown.
Common Applications for Thermal Water Leak Detection
Thermal water leak detection is an efficient and effective method for detecting and locating a wide range of leaks. It is most effective for detecting bathroom leaks, including leaks in shower recesses under-sinks or from taps and showerheads. Thermal leak detection is also great for detecting failures in waterproofing. Moreover, this method is highly effective for detecting leaks in roofing and ceilings, whether from rain, pipes, or roofing damage.
Leak detection specialists also frequently use this method when leaks are suspected but are not visible. This includes when clients report unexplained water usage or cost increases and unexplained mould growth. Thermal imaging cameras allow us to visualise the moisture and follow it back to an origin point.
A Recent Small Leak – Major Damage Case
Water has a surprising ability to travel well beyond where the leak first starts. One of our recent call-outs proved just how true this is.
A client called us out when they noticed the tap at their bathtub was leaking. Our leak detection specialists immediately pulled out the thermal imaging equipment to see just how far the water had travelled, and learn exactly what they were dealing with. As seen in the video above, the thermal imaging camera showed that the moisture had spread through the wall and down to the floor, causing significant water damage that wasn’t initially obvious.
This showcases the importance of contacting experienced leak detection specialists as soon as you suspect an issue. Swift detection = Minimal damage.
Never Underestimate a Small Drip or Leak
Leaks should never be underestimated, no matter how small they may appear. Even the smallest leak or slowest drip can waste litres of water and travel long distances, leaving a trail of destruction in its path.
With thermal water leak detection, we can make the invisible visible. This allows us to see the hidden damage lurking beneath the surface, within your walls, subflooring, cabinetry, and ceiling.
Don’t wait for a small leak to become a major hassle! If you know you have a small leak or even if you suspect one but can’t see it, give our leak detection specialists at LeakTech a call now for swift water leak detection.
