How we handle bath resealing in Trevethin

We reseal baths with them filled with water, so the joint is at its widest, so the seal doesn’t tear when the bath is first used. Our technicians work on wet rooms, baths and basins & vanity units, and people most frequently call us about leaks at the edges and silicone coming away from the tiles.

Whatever the size of the job, it’s backed by a one-year guarantee in Trevethin and across Torfaen.

Signs you need bath resealing in Trevethin

Black mould is the most common reason people reseal. It grows into the silicone, so cleaning can’t get it all out.

Typical reasons for a call-out include:

  • Unsealed corners
  • Black spots in the silicone
  • A messy previous reseal
  • Leaks at the edges

What your quote should include

  • What happens if they find more damage
  • Whether a trained technician does the job
  • How the colour is matched
  • Whether the price covers travel

10 questions to ask before you book

Why it’s worth resealing in Trevethin

Putting new silicone over old does not last. It peels within weeks, and traps mould underneath. A proper reseal removes the old first. 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.

Why book with us

  • A fixed quote before you book
  • Normally one visit, start to finish
  • One price list for the entire UK
  • Work done at your home or business

See our prices page.

How to look after the repair

A little care keeps the finish looking good. We recommend:

  • Don’t stand toiletries on the seal
  • Clean the sealant gently and regularly
  • Use the extractor fan
  • Reseal when black spots won’t clean off

Avoid scraping the joints, and do not stand bottles on the seal.

Mouldy sealant is more than a cosmetic problem; it shows moisture is getting in. An early reseal keeps water where it belongs.

Landlord and trade work in Trevethin

We work for landlords, letting agents and housing providers in Trevethin as well as householders. A repair between tenants keeps the property empty for less time, and it usually costs far less than a refit.

We’re used to working with agents and managing companies. Just send pictures, the address and how to get access.

What a repair can’t fix

Before you book, it’s worth knowing the limits too:

  • Gaps too big for silicone alone
  • Tiles that move, until they’re refixed
  • Movement in the bath or tray

Send us photos and we will tell you honestly before booking.

Materials we work on in Trevethin

  • Wet rooms
  • Shower trays & enclosures
  • Basins & vanity units
  • Kitchen worktops & sinks
  • Baths

Common questions in Trevethin

Can you reseal over the old silicone?

Never over old. It’s removed, cleaned off and the joint dried first.

Do you cover the whole of Torfaen?

The entire UK, including all of Torfaen. Send your postcode with your photos and we’ll confirm dates.

Is there any odour?

Expect a mild smell while we are working.

What information do you need?

Some pictures, your postcode and how to reach you. On the day, access to the room.

How quickly can you book me in?

Your quote comes with available dates. Tell us if you need it done quickly.

How long does silicone take to cure?

Normally about a day later. We confirm before we leave.

I’m a tenant. Can you help?

Yes, though it’s best to check with your landlord first. Landlords are frequently glad to have it sorted before the end of a tenancy.

What happens once I’ve sent photos?

We review the pictures and send a fixed quote and the next dates we have.

DIY repairs versus a professional job

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.

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, a professional repair is worth it.

Different materials, different repairs

Sinks and worktops

We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.

Shower trays

We put weight on a tray before sealing it, for the same reason.

How the visit works

We work cleanly and quietly, so you can stay at home while we’re there. Protection goes down first, then the job itself takes about two hours for a bath. Before we leave, we explain how soon it can be used and how to care for it.

  1. We cut out all of the old sealant.
  2. We remove the residue and clean the joint.
  3. Any mould is treated and the joint dried.
  4. We fill the bath, or weight the tray, to open the joint.
  5. New mould-resistant silicone is applied and tooled neatly.

Getting ready for the visit

  • Plan for the room to be out of bounds to pets and children
  • Tell us about parking, stairs or access
  • Open a window if you can
