How we handle bath resealing in Gabalfa
Resealing is quick, but it transforms the look. Clean, white joints make a bathroom look cared for, and they protect the walls and floor. Typical jobs include black spots in the silicone and a messy previous reseal, across basins & vanity units, baths and wet rooms.
All of our repairs are guaranteed for twelve months. We return to put right any problem with the work.

About Gabalfa
Gabalfa is about 1 mile west of Cardiff, in Cardiff. Whether you are in the middle of Gabalfa or on the outskirts, we offer exactly the same service: a fixed price, a tidy visit and a guarantee. Gabalfa is one of 91 towns and villages in Cardiff where we work.
All of CF14, CF5 and CF11 is covered, from the main roads to the quietest streets. That includes homes on Cefn Road, Court Road and Bacton Road and the roads around them. Gabalfa is on the A48 and A470, which makes it straightforward to reach. Close by, we cover Maindy (1 mile east), Gwaun Treoda (1 mile north), Llandaff North (1 mile west), Birchgrove (1 mile north) and Rhiwbina (2 miles north).

How to care for the repair
Once the work has cured, treat it gently:
- Wipe the joints dry after use
- Let steam out after showers
- Keep bottles off the joints
- Run the extractor fan during and after showers
Do not scrape the sealant with anything sharp, and keep shampoo bottles off the joints.
Do not wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.
Work for landlords and builders
We also carry out snagging repairs for builders and developers, putting right damage done during fitting. We are CHAS, Constructionline and SafeContractor accredited.
We regularly work with letting and managing agents. Just send pictures, the address and how to get access and we’ll arrange it.
DIY repairs versus a professional job
A kit can be fine for a tiny mark out of sight. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, a professional repair is worth it.
A DIY attempt is not a disaster. We take the old repair out and do it properly, so it does not stop a professional repair. Just mention it when you send pictures, as it can add time.

Your questions about bath resealing in Gabalfa
Is it worth repairing rather than replacing?
Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. We will be honest if it’s not worth it.
Do you charge for travel?
Travel is included in the price, and we charge the same wherever you are.
Do I have to be there?
We need someone to let us in. After that, you can carry on with your day.
Are you accredited?
We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.
Why does my sealant keep going mouldy?
Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.
Will the price change on the day?
We stop, show you and agree any change before carrying on. Nothing extra is done without your say-so.
