Leak Repair & Waterproofing

At Sealed Trading, we understand suffering a water pipe leak in your home or business can be extremely distressing, expensive and disruptive. This is why we have a team of highly experienced waterproofers and leak repair experts that will provide you with the reassurance that the leaking pipe will be found and fixed as quickly as possible, with minimum disruption and cost to you.

As professional waterproofers, we believe prevention is better than repair! Unfortunately most of the time we are called to inspect a shower or bath leak, 8/10 we’d find poor waterproofing workmanship or none at all.

When it comes to homes and commercial buildings, waterproofing is a critical element for protecting the building and preserving its value. Poor waterproof can fail, leading to cracks, mould issues, and even structural defects.

Fortunately, if you discover waterproofing issues earlier rather than later, you could remedy the problem avoiding the major headaches and huge repair costs later.

Shower Leak Repairs

Leaking Shower?


A leaking shower might not seem like a significant problem – after all, the water is in an area that gets wet all the time! However, leaks can cause mould, bacteria and rot to develop, leading to serious structural problems and health issues.

As well as causing cosmetic damage such as stains, leaks can also lead to severe damage requiring drywall and tiles to be entirely removed and replaced.

It is important to have a certified professional assess your shower and repair the cause of leaks as soon as possible to prevent serious damage.
