About our bath resealing in Trefechan
We reseal baths with them filled with water, so the joint is at its widest, which stops the new seal tearing the first time the bath is used. Common call-outs are for sealant that’s split or lifting and discoloured, yellow sealant, across wet rooms, basins & vanity units and baths.
Your repair is guaranteed for a year, as with every job we do.

DIY repairs versus a professional job
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is typically cheaper.

- 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.

- The colour and finish to match
What it costs depends on how much damage there is and what kind, what it’s made of and how many items we do on one visit. We give a fixed quote from your photos, so there are no surprises on the day.
Quotes from your photos
It only takes a minute to photograph the damage. Please include:
- Any earlier repairs or coatings
- One picture of the whole bath or shower
- The material, if you know it
- Natural light rather than flash

Aftercare tips
Most damage we see is avoidable. A few tips:
- Clean the joints with a mild cleaner
- Do not stand toiletries on the seal
- Ventilate the bathroom well
- Open a window after bathing
Use the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
Mouldy sealant is more than a cosmetic problem, it’s a sign moisture is sitting in the joint. An early reseal keeps water where it belongs.
Work for landlords and builders
We work for landlords, letting agents and housing providers in Trefechan as well as householders. Repairing between tenancies keeps void periods short, and it costs much less than replacing.
Rented homes see more wear and tear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.
