Bath resealing in Porthmadog without replacing anything
Preparation is everything in a reseal: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, in a neat, continuous bead. If you’re dealing with stained silicone and leaks at the edges, we can typically put it right, whatever the material.
Peace of mind is built in: our one-year guarantee applies to every job, and we explain what it covers before booking.

Why it’s worth resealing in Porthmadog
A reseal is one of the cheapest bathroom jobs there is and protects the walls and floor. Leaving failed sealant can let water cause damage that costs far more to fix. A few things move the price: access, material, the extent of the damage and whether we can do several items together. Photos let us give you a fixed figure.

What affects the price in Porthmadog
We give every job a fixed price from photos. These are the things that affect it:
- Any earlier repairs that need removing first
- Whether we combine several jobs
- How easy the damage is to reach
- The colour and finish to match
No two jobs are quite the same, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all make a difference, and doing several things on one visit costs less than separate visits.
Getting a price from photos
It only takes a minute to photograph the damage, and it saves a visit. Try to send:
- The material, if you know it
- A wider photo showing the whole bath or shower
- Daylight if possible, and no flash reflection
- A coin beside the damage so we can judge size
If you are in Porthmadog and want a price, photos are the quickest way: one close up, one from further back, plus your postcode. You will get a fixed quote with dates to choose from.
Materials and what they mean for the repair
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
What a repair can’t fix
It helps to know what we can’t do too:
- Gaps so wide they need filling or trims before sealing
- Tiles that move, until they’re refixed
- Water damage behind the bath that needs a builder
If in doubt, send photos and we’ll say what we think.
Surfaces we repair
- Kitchen worktops & sinks
- Wet rooms
- Basins & vanity units
- Shower trays & enclosures

DIY repairs versus a professional job
A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.
It’s tempting to reach for a kit, but the repairs we redo most often are DIY ones that have discoloured or lifted. Getting it right first time is generally cheaper.
FAQs for Porthmadog
Do you come to Porthmadog?
Yes. We cover the whole UK and travel to Porthmadog and the rest of Gwynedd. Send us pictures for a fixed quote, or call 0345 017 0787.
What happens next?
You get a fixed price and available dates. If we need another angle, we will ask.
Is the work guaranteed?
Yes, for a year. If anything goes wrong with the repair within the year, we return to fix it.
Why does mould come back so fast?
Mostly moisture and poor ventilation. We use mould-resistant silicone, and ventilation helps it last.
Can tenants book a repair?
Yes. Ask your landlord first, and we can send them the quote if that helps.
How long does silicone take to cure?
Normally about a day later. We confirm before we leave.
Can new silicone go over old?
We always remove the old sealant completely. New silicone will not bond to old.
Is it OK to have pets in the house?
Please keep children and pets out of the room during the visit and until it has cured. Everywhere else in the home is fine.
What we do, step by step
Here’s how a visit typically runs: we arrive on time, sheet and mask the area around the job, carry out the work and tidy away. Allow about two hours for a bath. Before we go, we’ll explain how long to leave it and what to avoid for the first few days.
- We cut out all of the old sealant.
- Residue is removed and the joint cleaned.
- Any mould is treated and the joint dried.
- We fill the bath, or weight the tray, to open the joint.
- We apply fresh mould-resistant silicone and tool a neat bead.
Preparing for the visit
- Tell us about parking, stairs or access
- Have a window or extractor fan available
- Point us to the nearest place to park
Get a quote
You do not need a survey visit. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll reply with a fixed price.
Advice
How to care for the repair
Good habits make a big difference to how long a repair lasts:
- Air the room after use
- Reseal at the first sign of lifting
- Use the extractor fan
- Clean the joints with a mild cleaner
Run the extractor fan, wipe the joints dry after use, and clean them regularly with a mild cleaner to slow mould growth.
Do not wait until water gets behind the bath. Gaps or lifting edges mean it needs doing.
When to call us in Porthmadog
Sealant splits when the bath or tray moves, frequently because it was sealed with the bath empty.
It’s worth getting a quote if you see:
- Mould you cannot clean out
- Unsealed corners
- Gaps in the seal
- Stained silicone
Comparing quotes
- Is the price fixed, and does it include VAT?
