Why Is My Shower Leaking Around the Tray?

A leaking shower isn’t always caused by faulty plumbing.

In many cases, the problem starts with something much simpler — failed sealant around the shower tray, enclosure, or surrounding joints. What often begins as a small gap or crack can gradually allow water to escape behind surfaces, leading to damp patches, mould growth, and damage that isn’t immediately visible.

The good news? In many situations, the solution is far less disruptive than homeowners expect.

The Most Common Cause of Shower Leaks

Shower trays and enclosures are designed to keep water contained within the shower area. The sealant surrounding these joints plays a vital role in preventing moisture from escaping.

Over time, silicone can begin to:

  • Crack
  • Shrink
  • Peel away from surfaces
  • Develop mould
  • Lose flexibility

Once gaps appear, even small amounts of water can work their way behind the tray or wall panels.

Because this often happens gradually, many homeowners don’t notice the problem until signs of damage start appearing elsewhere.

 

Signs Your Shower Sealant May Be Failing

One of the easiest ways to identify a sealant issue is by inspecting the silicone around the shower tray.

Common warning signs include:

  • Black mould within the sealant
  • Cracked or split silicone
  • Peeling edges
  • Discolouration
  • Visible gaps between surfaces
  • Water collecting outside the shower area

If any of these issues are present, the sealant may no longer be providing effective waterproof protection.

 

Could the Leak Be Coming From Somewhere Else?

Possibly.

While failed silicone is one of the most common causes of shower leaks, there are situations where the issue may be related to:

  • Damaged grout
  • Plumbing connections
  • Faulty shower trays
  • Loose fittings
  • Structural movement

A professional inspection can usually identify whether the sealant is the source of the problem or if further investigation is required.

 

Why Adding More Silicone Isn’t Always the Answer

A common mistake is applying new sealant directly over old silicone.

Although it may appear to solve the problem temporarily, old sealant often contains trapped moisture, mould, and weakened adhesion. Applying fresh silicone over the top can result in poor bonding and further failure.

For long-lasting results, the existing sealant should be fully removed before new silicone is applied.

Can Mouldy Silicone Be Cleaned or Should It Be Replaced?

What Happens If You Ignore It?

Small leaks have a habit of becoming larger problems.

Water penetrating behind shower trays or wall panels can eventually lead to:

  • Damp patches
  • Mould growth
  • Damaged plasterboard
  • Loose tiles
  • Stained surfaces
  • Costly repairs

Addressing failing sealant early is often far more affordable than repairing water damage later.

When Should Shower Sealant Be Replaced?

There is no exact lifespan because every bathroom experiences different levels of use, ventilation, and moisture exposure.

However, if the sealant is visibly mouldy, cracked, peeling, or allowing water to escape, replacement is usually the most effective solution.

Professional resealing restores the waterproof barrier while improving the overall appearance of the shower area.

Choosing the Best Mastic Sealant for Your UK Kitchen: Essential Tips and Expert Advice

When it comes to kitchens, mastic sealants are key to keeping your space watertight, clean, and protected from daily wear and tear. High-quality sealants provide essential moisture resistance, prevent mould, and can even enhance the overall look of the kitchen. Whether you’re a homeowner looking to DIY or considering the expertise of a professional mastic man, finding the right mastic sealant can make all the difference.

Why Mastic Sealant Is Essential in Kitchens

The kitchen is one of the busiest and most moisture-prone areas in a home. With exposure to water, heat, and frequent cleaning, surfaces can degrade over time if not properly sealed. Mastic sealant protects critical areas around sinks, countertops, splashbacks, and even near appliances, preventing water damage and maintaining a clean, polished look. Choosing a durable, long-lasting sealant keeps these areas resistant to everyday spills, grease, and humidity, extending the life of your kitchen.

 

Top Mastic Sealants for UK Kitchens

Selecting the right sealant for your kitchen depends on the specific area, as some spots require more flexibility, mould resistance, or temperature tolerance than others. Here are a few of the best options for different kitchen needs:

Silicone Sealant with Mould Resistance

Given the UK’s damp climate, mould resistance is especially important for kitchen sealants. Mould-resistant silicone is ideal for areas exposed to moisture, like around sinks and splashbacks. These sealants create a barrier that resists mould build-up, helping to maintain a cleaner, healthier environment.

Flexible Silicone for High-Moisture Areas

Flexible silicone is a popular choice for its elasticity, perfect for areas that experience movement or minor settling. It adheres well to non-porous surfaces like tiles and metal, making it ideal for joints around sinks and countertops. This type of sealant is waterproof, durable, and provides a seamless look.

High-Temperature Sealant for Hob and Oven Areas

In areas close to high heat sources, such as hobs and ovens, high-temperature mastic sealant is designed to withstand the heat without shrinking or cracking. This makes it an excellent choice for zones that need extra protection from temperature fluctuations.

Paintable Acrylic Sealant

For those who want a cohesive look, paintable acrylic sealant can be an attractive choice. It’s perfect for areas where you may want the sealant to blend in with surrounding surfaces, such as near painted splashbacks or custom cabinetry. Acrylic sealant is easy to apply and paint over, offering more flexibility for customisation.

Non-Yellowing Sealants

Over time, traditional silicone sealants can yellow or lose their clarity, which affects the overall appearance of the kitchen. Non-yellowing sealants are UV-resistant, keeping their colour longer. They are ideal for areas exposed to natural light or where you want a clear, clean finish.

Benefits of Hiring a Professional Mastic Man

While some sealant jobs can be done DIY, the precision and durability offered by a professional mastic man are well worth considering. Here are some reasons to hire a specialist for your kitchen project:

Expertise and Precision

A professional has the skill and experience to apply sealants smoothly and accurately, preventing common issues like air bubbles, uneven lines, or gaps. This is especially valuable around sinks, counters, and splashbacks, where a watertight seal is essential.

Access to Quality Materials

Professionals use high-quality, commercial-grade sealants that may not be available in retail stores. These sealants offer better mould resistance, adhesion, and durability, which means you get a lasting finish.

Efficient and Cost-Effective

A professional job saves time and reduces the likelihood of mistakes that might require costly rework. By investing in a quality application the first time, you’ll enjoy a kitchen that looks and performs its best without the need for constant touch-ups.

Tips for Maintaining Your Kitchen Sealant

Routine Cleaning

Use gentle, non-abrasive cleaners to maintain the sealant’s appearance and prevent the build-up of dirt or grease. Avoid using harsh chemicals that could damage or discolour the sealant over time.

Inspect Regularly

Check around sinks, countertops, and splashbacks for signs of wear or damage. Small cracks or areas of peeling can usually be repaired quickly, helping you avoid larger issues down the line.

Address Mould Immediately

If you notice any mould build-up, clean it right away to prevent it from spreading. Use a soft brush and a mild bleach solution, or try a mould remover specifically designed for kitchen use.

Avoid Heat Damage

Keep an eye on any sealants near heat sources, such as the hob or oven. High-heat sealants are generally resilient, but it’s always a good idea to check that they’re holding up well and free of cracks.

Where to Use Mastic Sealant in Your Kitchen

Knowing the best areas for mastic sealant helps protect and maintain your kitchen. Here’s where sealant is most beneficial:

Sink and Tap Surrounds

Applying mastic sealant around the sink and tap edges prevents water from seeping into cabinets or countertops. A high-quality, mould-resistant silicone works well here, keeping the area sanitary and secure.

Countertop Edges

A seamless, finished edge along countertops prevents food particles and moisture from getting trapped. Flexible silicone is an excellent choice for a clean look and lasting durability.

Splashbacks

Sealant around splashbacks prevents grease and food residue from damaging the wall or seeping behind tiles. High-temperature or non-yellowing silicone is a good match for these areas.

Near Appliances

Sealant around the hob and oven adds an extra layer of protection from heat and spills. Using a high-temperature mastic here can help maintain a clean, safe kitchen space.

How to Maintain Silicone Sealant: A Complete Guide

In this guide, we’ll cover the best ways on how to maintain silicone sealant, when to call in a professional mastic man for a flawless finish, and how to avoid common issues.

Silicone sealant is a key feature in many British homes, especially in high-moisture areas like bathrooms, kitchens, and around windows. Its flexibility, waterproof properties, and long-lasting durability make it ideal for keeping spaces protected from water ingress and drafts. However, to ensure that silicone continues to perform well over time, it needs regular maintenance.

Why Silicone Sealant Maintenance Is Important

In the UK, our damp climate and frequent changes in temperature can quickly affect sealant. Silicone, when left unattended, can become mouldy, discoloured, or begin to peel and crack, especially in bathrooms and kitchens. Poorly maintained silicone can lead to leaks, drafts, and water damage, which in turn can compromise the overall integrity of your home. Regular maintenance helps:

  • Extend the lifespan of the sealant
  • Keep it looking clean and fresh
  • Prevent the growth of mould and mildew
  • Ensure a strong, watertight seal

Whether your silicone sealant is new or has been in place for years, a little bit of care can go a long way in keeping it effective.

Regular Cleaning

One of the easiest ways to maintain your silicone sealant is through regular cleaning. Keeping the area clean helps to prevent dirt and mould from taking hold, which can deteriorate the silicone over time.

How to Clean Silicone Sealant:

  • Use mild soap and water: Start by wiping down the silicone with a mixture of warm soapy water. This will remove any surface dirt or grease. Harsh chemicals such as bleach can weaken the sealant, so it’s best to avoid them.
  • Use a soft sponge: When cleaning, use a soft cloth or sponge to avoid damaging the silicone surface. Abrasive pads or scrubbing brushes could tear the sealant.
  • Rinse thoroughly: After cleaning, rinse the area with clean water to remove any soap residue, which could attract dirt later on.

It’s recommended to clean silicone sealant every couple of weeks, especially in high-use areas like around sinks, baths, or shower cubicles.

Preventing and Removing Mould

In humid environments, like bathrooms, mould can be a persistent problem. When mould builds up on silicone, it can not only look unsightly but also degrade the sealant’s effectiveness. Keeping the area dry and well-ventilated can help prevent this, but if mould does appear, it’s important to act quickly.

How to Remove Mould from Silicone Sealant:

  • Use white vinegar: A natural and non-abrasive cleaner, white vinegar is great for removing mould. Simply apply vinegar to the affected area, leave it for 20-30 minutes, and gently scrub with a soft brush.
  • Try a silicone-friendly mould remover: If vinegar isn’t enough, there are silicone-safe mould removers available in the UK that can help. Always check the product is suitable for use on silicone and follow the manufacturer’s instructions.

To prevent mould from coming back, ensure the area is well-ventilated, use an extractor fan, and wipe down wet areas regularly.

Inspecting for Damage

Regularly inspecting your silicone sealant for signs of damage is vital to maintain its integrity. Over time, silicone can become brittle, crack, or pull away from the surface it’s protecting, especially in areas that see a lot of movement, such as windows or doors.

How to Inspect Silicone Sealant:

  • Look for visible damage: Check for any cracks, peeling, or gaps. Even small splits can allow moisture to seep in, which can cause damage to the surfaces underneath.
  • Check flexibility: Silicone sealant should remain slightly flexible. If it feels rigid or begins to crumble, it’s time for replacement.

If you spot any of these issues, it’s important to repair or replace the sealant before any serious problems develop.

Reapplying Silicone Sealant

If your silicone sealant is damaged, mouldy, or beyond cleaning, it’s time to reapply. While it’s possible to tackle this job yourself, achieving a professional finish can be tricky. For best results, it’s often worth hiring a professional mastic man to ensure that the job is done right.

How to Remove Old Silicone Sealant:

  1. Cut away the old sealant: Use a silicone removal tool or a sharp stanley knife to carefully scrape away the old sealant. Take care not to damage the surrounding surfaces.
  2. Clean the area: Once the old silicone has been removed, clean the area with a silicone remover or rubbing alcohol to get rid of any residue.
  3. Allow the surface to dry: Ensure the area is completely dry before applying new silicone, as any moisture can prevent the new sealant from bonding properly.

How to Apply New Silicone Sealant:

  1. Use a sealant gun: For controlled application, use a silicone sealant gun. Cut the nozzle at a 45-degree angle, ensuring the bead is the right size for the gap you’re sealing.
  2. Apply the silicone smoothly: Slowly apply a continuous bead of silicone along the joint. Don’t worry if the bead looks a little uneven at first.
  3. Smooth the sealant: Using a smoothing tool or your finger (dipped in soapy water), smooth the bead for a clean, professional finish.
  4. Allow to cure: Silicone usually takes 24 to 48 hours to fully cure, so avoid touching or exposing it to water during this time.

If you’re not confident in reapplying silicone yourself, hiring a professional mastic man is a smart investment. A mastic man has the skills and tools to apply silicone quickly and accurately, ensuring a smooth, durable, and watertight finish.

Tips to Prolong the Life of Silicone Sealant

Once your silicone sealant is freshly applied or cleaned, there are a few ways to help it last longer and avoid frequent repairs:

  • Keep areas dry: In high-moisture environments, such as bathrooms, wipe down the silicone after each use to prevent water build-up.
  • Ensure proper ventilation: Make sure rooms where silicone is used are well-ventilated. Open windows, use an extractor fan, or install a dehumidifier to keep humidity levels low.
  • Avoid harsh chemicals: Regular household cleaners can break down silicone over time. Stick to mild, non-abrasive cleaning solutions.

Why Hire a Professional Mastic Man?

While maintaining silicone yourself is manageable, for more extensive repairs or reapplication, hiring a professional mastic man ensures the job is done to the highest standard. A mastic man has specialised training in applying sealant smoothly and precisely, achieving a finish that not only looks professional but is also built to last. Whether you’re dealing with bathroom sealant, kitchen surfaces, or external joints around windows, a mastic man guarantees flawless results, saving you time and hassle in the long run.

Final Thoughts

Proper maintenance of silicone sealant is key to keeping your home protected from moisture and drafts. Regular cleaning, inspecting for damage, and reapplying when necessary can prolong its life and ensure it continues to do its job effectively. When it comes to reapplication or difficult areas, hiring a professional mastic man is a wise choice to ensure a professional finish. With the right care, silicone sealant can keep your home watertight, airtight, and looking its best for years to come.
