Identifying the Need for Resealing Shower Tray
First things first, let's make sure your shower tray actually needs resealing. Spotting the problem early can save you from costly water damage later on. Here are a few tell-tale signs to look out for:
Visible Water LeaksThis one's pretty obvious. If you see water pooling on the floor outside your shower, it's a clear sign that the sealant has failed and could use a bit of resealing.
Mould and MildewSeeing black or dark green spots on or around the sealant? That's mould. It means water has gotten behind the seal, creating the perfect damp spot for it to grow.
A Persistent Damp SmellIf you notice a musty smell that just won't go away, no matter how much you clean, it could be a sign of hidden moisture and mould behind the sealant or under the tray.
If you notice any of these signs, it's time to get to work. Reseal shower pan quickly to stop a small leak from turning into a big headache.
Damaged or Peeling Sealant
Take a close look at the sealant itself. If it's cracking, shrinking, or peeling away from the wall or tray, it's not doing its job of keeping water out anymore.
Mistakes Homeowners Often Make When Resealing Shower Trays
Even with the best intentions, it's easy to mess things up when resealing a shower tray. So, let's talk about the common blunders people make and how you can totally steer clear of them:
Forgetting to Prep the Area Right
This is probably the number one mistake when resealing a shower tray! You have to get rid of all that old sealant and make sure the joint is squeaky clean. If you don't, your new sealant won't stick to dirt, moisture, or leftover gunk.
Grabbing the Wrong Sealant
Not all sealants are created equal. If you grab just any old general-purpose or acrylic caulk instead of a 100% silicone, mould-resistant bathroom sealant, you're just asking for trouble. It'll fail quickly, discolour, and you'll get mould.
Putting On Too Much or Too Little
Too much sealant can also lead to a messy, unprofessional look, and it'll be a nightmare to smooth. Too little? It won't fill the gap properly, leaving weak spots and potential leaks. The secret is a nice, consistent, just-right bead.
Skipping the Smoothing Step
If you don't smooth the sealant, it'll look uneven, and more importantly, it won't get pushed deep enough into the joint. That means air pockets and a weak seal, which is no good.
Being Impatient with Curing
Patience is a virtue here. If you jump in the shower before the sealant has fully cured, you'll either wash it away or stop it from bonding correctly. All that hard work will be totally wasted.
How Much to Reseal Shower Tray in London?
Wondering how much it costs to reseal a shower tray? The reseal shower tray costs vary depending on several factors.
Resealing shower tray by yourself? You're mainly looking at material costs. A good tube of silicone sealant, a sealant gun, and some cleaning bits will probably set you back around £20 to £40.
Now, if you get a professional to reseal your shower tray in London, you're usually looking at something between £80 and £200. That covers their time and materials. Sure, it's more expensive, but you get the peace of mind knowing it's done right and often comes with a guarantee.
Factors Affecting Professional Cost to Reseal a Shower Tray
Here are a few things that can affect the reseal shower tray cost:
- The size of your shower: Larger showers naturally take more time and materials to reseal.
- The condition of the existing sealant: If the old sealant is particularly stubborn, it might take a bit longer to remove it all.
- The complexity of the job: Tricky corners or unique shower designs can make the resealing shower tray process more challenging.
- Labour costs: Labour rates can vary across London. We always offer clear and competitive pricing for all our handyman services.

How Long Do Shower Trays Last?
Want your shower tray to last? A good one can stick around for 10-15 years, maybe even longer! But how long it actually lasts really comes down to a few things:
- What is it made of? Acrylic and stone resin trays are tough, but the quality can totally differ depending on who made them.
- How was it installed? If it wasn't put on a flat, solid base, it's more likely to wobble and crack over time.
- How do you look after it? Keeping it clean regularly and resealing the shower tray when needed is important. That sealant, especially, should probably be replaced every year or two to keep things watertight.
