Bath resealing at your home in Brynawel
We reseal baths, shower trays, basins and worktops, with mould-resistant sanitary silicone. Most jobs take a couple of hours, then it needs to cure. We regularly repair baths, wet rooms and kitchen worktops & sinks, and common reasons people get in touch are old sealant that looks dirty and missing sealant behind the taps.
All of our repairs are guaranteed for twelve months, and the guarantee is the same wherever you live. We return to put right any problem with the work.

Work for landlords and builders
Hotels, guest houses and holiday lets can’t afford rooms out of action for long, so we keep visits short and tidy. We’ll fit around changeovers where we can.
For developers and builders, we fix damage before handover, saving last-minute replacements. Several plots can be done in one visit.

Look out for these signs:
- Sealant that is split or lifting

- Stained silicone
- A messy previous reseal

Materials and what they mean for the repair
Baths
We fill the bath before sealing, so the joint is at its widest.
Shower trays
We put weight on a tray before sealing it, for the same reason.
Brynawel: your questions answered
Is it worth repairing rather than replacing?
In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. If it is not worth repairing, we will tell you.
Can you quote from photos?
In nearly every case. If photos don’t show enough, we’ll ask for another angle.
Why does my sealant keep splitting?
Something is moving. If it keeps happening, the support may need fixing.
How long does resealing take?
Most reseals take about two hours. Leave it to cure before use.
Can you do more than one item on the same visit?
Yes. Doing several items on one visit typically costs less than separate visits. Send pictures of everything you’d like done.
Are you a vetted contractor?
We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.
How much does bath resealing cost in Brynawel?
The exact price depends on the damage, so we quote from pictures. You know the full cost before anything is booked.
How soon can you come?
It depends on the time of year and where you are. Send photos with your postcode and we’ll reply with the earliest dates.

Prices and what affects them
We do not charge extra for travel to Brynawel. The price comes down to:
- The colour and finish to match
- The material and finish
- How many areas need work
- What kind of damage it is
The price depends on the type and amount of damage, what it’s made of and how many items we do on one visit. You get a fixed price from your photos, so there are no surprises on the day.
Send pictures for a quote
You can take the pictures on your phone. Ensure they show:
- Natural light rather than flash
- A coin beside the damage so we can judge size
- One picture of the entire bath or shower
- A close-up of the damage, in focus
A quote takes minutes to ask for: take one close-up and one wider shot of the bath or shower, add your postcode and send them over. What comes back is a fixed quote, not a guess.
Should I try a DIY kit first?
The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.
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 normally cheaper.
Aftercare tips
So the finish stays in good condition:
- Keep the joints dry
- Store bottles on a shelf
- Use the extractor fan
- Reseal at the first sign of lifting
Use the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
Reseal before water gets in. Split or lifting sealant is a sign it’s time.
Resealing in Brynawel: why it matters
Putting new silicone over old does not last. It peels within weeks, and mould stays trapped behind it. A proper reseal removes the old first. A repair normally costs much less than people expect, especially compared with replacing and refitting. Send photos and we’ll give you the exact figure.
