What Causes a Shower Leak? 

Although there are so many hidden reasons that can cause shower leaks in your bathrooms that are not easily evident. But here are some factors that are common factors that can damage your pipelines. 

Faulty Waterproofing 

The role of a waterproofing system is to protect against water damage, prevent mold and mildew build-up, and ensure long-term structural integrity. If the materials or components are not compiled appropriately, then everything can be worthless.

Cracked Grout and Tiles

Over time, the bathroom floor will go through wear and tear that can be caused by accidental impacts or shifting building foundations. .Moisture and water will seep through the cracks between grout and tiles, soaking into the subfloor. Moisture damage can happen if it is not fixed right away.

Damaged Shower Seals 

Similar to waterproofing, seals in glass panels, shower screens, and the base of a shower unit prevent water from leaking into other parts of the shower area. When they start to degrade due to general wear, age, or constant use of cleaning chemicals, they lose their efficacy and flexibility. Water can start seeping through the gaps and tears.

Plumbing Problems 

A leaky shower head is just one of the causes of water damage within the shower area. Those pipes that are established during the building development or are prone to corrosion can also cause a drastic impact. If there are loose connections between pipes, water can drip through them as well. The constant dripping may seem more annoying than damaging, but it can lead to bigger and more expensive issues.

Why Should You Worry About a Leaky Shower?

Mould Growth

A shower leak is not only detrimental to the health of your home but also to yours. Damp and poorly ventilated areas are the perfect breeding ground for mold. Mold could be to blame if you notice a musty smell coming out of your bathroom, no matter how often you clean it, if you notice a musty smell coming out of it. Exposure to the tiny spores that it releases can cause health problems, such as sore throat, coughing, and nasal congestion.

Don’t wait for severe asthma attacks or respiratory concerns to occur before you get rid of mold. Better yet, prevent growth by controlling moisture levels in your bathroom. If the infestation already persists or has become a major difficulty, a major overhaul might be needed to get rid of the concern once and for all. Remodelling for your overall health is always a worthy investment.

Higher Water Bills 

Even if you don’t notice the leak in your shower, you will surely notice the increase in your water bill, especially with the same level of consumption. Why would it suddenly spike if you’re using the same amount of water day in and day out? That’s because you could be wasting up to 20 litres per day without realizing it.

Expensive Repairs

If the leak has started damaging the overall framework, then it’s better to invest time and opt for expensive repairs. As you can see, leaks in the shower or other parts of your home can become a major difficulty when neglected. 

It’s best to fix the concern as soon as you notice it then wait for it to impact your property, health, and peace of mind.
