What You'll Learn
Subterranean termites are attracted to damp timber
A leaking shower pan can indeed cause a termite infestation. Subterranean termites are attracted to damp timber and are known to live in damp, moisture-rich conditions. They survive by avoiding drying out. They typically live and travel deep within the soil outdoors. However, when they detect damp timber due to a leak, they can enter your home by digging mud tunnels to climb exterior walls and enter through tiny cracks and crevices.
Subterranean termites are social insects that live in colonies containing caste systems. A mature subterranean termite colony can consist of anywhere between 60,000 and two million workers. They use their scissor-like or saw-toothed jaws to eat wood 24 hours a day, seven days a week. They also feed on products containing cellulose, which is found in wood. Over time, they can critically damage a building's structure, sometimes causing a total collapse.
To prevent subterranean termite infestations, it is important to avoid water accumulation near the foundation of your home. Ensure proper ventilation and reduce humidity in crawl spaces. Seal any cracks and crevices in your home's foundation, and never bury wood scraps or waste lumber in your yard. Additionally, maintain a one-inch gap between the soil and wood portions of your home.
If you suspect a leaking shower pan, it is important to address the issue promptly. Contact a professional to identify and resolve the leak. This may involve re-grouting, resealing, retiling, or shower waterproofing. Taking preventative measures can help save you from costly repairs and pest infestations in the future.

Shower leaks can cause mould growth
A leaking shower pan can indeed cause termites. Subterranean termites are timber pests that live in damp, moisture-rich conditions and can enter your home through tiny cracks and crevices. They can also enter your home through the roof or the gutter.
Now, shower leaks can cause mould growth in several ways. Firstly, when water seeps from a shower into crevices, cracks in the grouting, and wall cavities, it provides the perfect conditions for mould spores to take root and thrive. Mould spores are always present in the air we breathe, waiting for moisture to multiply. The porous materials in your home's walls absorb excess water from a leaking shower, allowing mould spores to activate, spread, and multiply into colonies. Once mould growth has started, the colonies can rapidly expand beyond the shower area, spreading to walls, ceilings, and adjacent rooms as they follow the available moisture. This can create a widespread and deep-rooted problem that is challenging to treat.
Secondly, a leaking shower can cause mould growth by providing a persistent food source for mould to flourish throughout a home. Even small leaks that allow moisture to penetrate walls can be problematic, so it is essential to address minor leaks promptly to prevent mould issues from escalating.
Additionally, the type of shower surround you have can impact mould growth. Stone tile surrounds, for example, are prone to grout and caulking issues and can experience mould growth within the stone itself. In contrast, porcelain tile is less porous and less likely to facilitate mould growth, although grout and caulking can still fail. A 3-piece fiberglass surround has limited failure points, while a 1-piece surround provides very few failure points and is highly effective at preventing mould.
To prevent mould growth, it is crucial to identify and fix any leaks immediately. For minor seal or grout issues, DIY re-sealing or re-grouting may be sufficient. However, for more severe leaks or water damage, it is advisable to engage a professional shower repair service to correctly identify and address the source of the leak.
Furthermore, installing a leak-proof shower unit or a prefabricated shower cubicle can help prevent mould growth by containing water within the shower walls. These units are made of solid surfaces or composites instead of tiles, eliminating the possibility of leaks through damaged grout lines or cracked tiles.

Signs of termite damage in bathrooms
Leaking showers can cause several issues, including mould growth, cracked tiles, and chipping or peeling wallpaper. However, one of the most serious underlying problems is the potential for termite infestations. Subterranean termites, in particular, thrive in damp and moisture-rich conditions, making bathrooms an attractive target. Here are some signs of termite damage in bathrooms:
Structural Damage
Termites can cause significant structural damage by eating through damp wood at an alarming rate. They are drawn to wet wood and can enter your home by digging mud tunnels through exterior walls, tiny cracks, or even the roof. Look out for damage to the corners of walls, with scraps or tiny shavings of wood collecting at the bottom. This could indicate that termites are eating away at the structural wooden beams, which can be costly and challenging to repair.
Bubbling Paint and Wall Disintegration
If you notice bubbling on painted wall surfaces or disintegration of drywall or panelling, it could be a sign of termite activity. Termites create holes in these surfaces, causing the paint to bubble and the walls to deteriorate.
Moisture and Condensation
Termites are attracted to moisture, so bathrooms with inadequate ventilation or leaking pipes can be at risk. Moisture can soak into walls, getting into gaps and cracks, creating the humid conditions that termites favour. If you notice excessive moisture or condensation in your bathroom, especially around wooden structures, it may be a good idea to check for termites.
Mud Tunnels and Shelter Tubes
Subterranean termites create mud tunnels and shelter tubes for protection as they move in search of food. These structures can be spotted on exterior walls or even inside your home. Shelter tubes appear as wiggly mud lines about the width of a pencil. If you see these, it's a strong indication of termite activity.
Spring Swarms
Keep an eye out for swarmer termites during the spring months. These termites have wings and are darker in colour, resembling ants. They tend to swarm in spring and can be a clear sign of an infestation.
It's important to address any water leaks or ventilation issues in your bathroom to reduce the risk of termite infestations and prevent costly repairs. If you suspect termite activity, it's best to contact a professional for inspection and appropriate treatment.

How to identify a leaking shower pan
A leaking shower pan can have several negative consequences, including mould growth, water damage, and, in some cases, termite infestations. Here are some detailed steps to identify a leaking shower pan:
Inspect for Physical Movement
Shower pans should be firmly secured to the floor and should not move or shift. If you notice any movement, no matter how minor, it could indicate a potential leak. This movement can be caused by the breakdown of securing materials over time or even major vibrations, such as an earthquake.
Check for Cracks
Inspect your shower pan for tiny cracks, which can form from even the smallest movements. These cracks may allow water to pass through unnoticed, leading to potential leaks. If you have a plastic pan, any cracking indicates a failure, while with sturdier materials like porcelain, cracks in the pan itself are a warning sign.
Seal the Drain and Fill the Pan
To perform this test, seal the drain using waterproof duct tape, a plug, or plastic sheeting. Then, fill the shower pan with an inch or two of water and mark the water level with a sharpie. Leave the water for several hours or overnight, and then check if the water level has dropped. If it has, there is likely a leak in your shower pan.
Observe for Deflection
Deflection refers to an up-and-down movement of the shower pan, indicating that the floor beneath may be giving out due to water damage. This movement can also cause unusual sloping in the shower pan, making it feel unstable when stepping in or out.
Check for Water Damage
Inspect the bathroom floor around the shower pan and the ceiling in the room directly below the bathroom for visible water damage or staining. This can include mouldy silicone joints, cracked tiles, chipping, peeling, or flaking wallpaper. These signs may indicate a leaking shower pan, which could lead to more severe issues like termite infestations.
Remember, if you suspect a leaking shower pan, it is essential to address the problem promptly to prevent further damage and ensure the safety of your home.
