How we handle bath resealing in Penge
A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and a new seal stops it. We work on basins & vanity units, shower trays & enclosures and wet rooms, and people most often call us about missing sealant behind the taps and leaks at the edges.
The work is guaranteed for twelve months. If there’s a problem with the repair within the year, we return and sort it.

How the visit works
Nothing needs to be moved out of the room. We bring everything we need with us, lay protective sheets and get going once we have agreed what we are doing. It normally takes a couple of hours, and you can get on with other things while we’re there.
- The surrounding area is protected and the joints masked.
- Old sealant and residue are removed.
- We clean, treat and dry the joint.
- We run a continuous bead of new silicone.
- We smooth the bead, remove the tape and leave it to cure.
Before we arrive
- Plan for the room to be out of bounds to pets and children
- Mention any parking restrictions or tricky access
- Move bottles, mats and clutter away from the area
Getting a price
There’s no need for us to visit first. Nearly every job can be priced from photos: send a close-up, a wider shot and your postcode, and we will come back to you with a fixed figure.
Related advice
Aftercare tips
Simple care helps the repair last. Our advice:
- Wipe the joints dry after use
- Give the seal a regular clean
- Keep bottles off the joints
- Replace the seal when mould sets in
Let it cure fully before using the bath or shower, normally about a day.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. There may be more going on, and we’ll say if you need a builder or plumber.
Repairs by material
Baths
We fill the bath before sealing, to open the joint fully.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Is resealing worth it?
Resealing is a small job. Putting off a reseal lets water get behind the bath or tray, and that damage costs much more to fix. Set against the cost of replacement, repairing usually costs far less, because there’s no removal, plumbing or making good. The quote lists exactly what you are paying for.

Your questions about bath resealing in Penge
It’s been repaired before. Can you still fix it?
Generally, yes. Let us know what was used before and we will plan for it.
Do you cover Penge?
Yes. We work across the UK and come to Penge and the rest of Greater London. Send pictures and we will quote, or call 0345 017 0787.
My seal keeps tearing. Why?
Typically because the bath or tray moves, or it was sealed with the bath empty. We seal baths full of water.
Can tenants book a repair?
Of course. Check with your landlord; we can send the quote to them too.
Why does mould come back so fast?
Mostly moisture and poor ventilation. We use mould-resistant silicone, and ventilation helps it last.
Is it safe with children and pets around?
We ask you to keep children and pets out of the room while we work. The rest of the house is unaffected.
Do I have to be there?
Yes. We need access to the room while we work, at a time we agree with you.
Is a repair better than a new one?
Generally, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. We’ll tell you honestly if replacement makes more sense.
DIY repairs versus a professional job
For a hairline mark somewhere you’ll never see, a kit may be enough. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.
It’s natural to want to try a repair yourself. The risk is that a kit repair hides the damage for a while, then fails, and then the old filler has to be removed first.
Work for landlords and builders
We regularly price jobs from inventory or check-out pictures. You can have a price before you arrange access, and we liaise with tenants about access if you’d like us to.
Rented homes see more wear and tear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.
