About our bath resealing in Llanarth

Preparation is everything in a reseal: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, as one neat, continuous bead. Typical jobs include mould you can’t clean out and water getting behind the bath or tray, in shower trays & enclosures, wet rooms and kitchen worktops & sinks.

Peace of mind is built in: each job carries a one-year guarantee, and we explain what it covers before booking.

Work for landlords and builders

Hotels, guest houses and holiday lets need rooms back in use quickly, so most of our work is done in a single visit. We will fit around changeovers where we can.

Letting agents often send us pictures straight from the inventory. That means we can quote before you even visit the property, and we liaise with tenants about access if you’d like us to.

Aftercare tips

It’s all simple stuff, just a few sensible habits:

  • Ventilate the bathroom well
  • Open a window after bathing
  • Don’t stand toiletries on the seal
  • Clean the joints with a mild cleaner

Keep the room well ventilated, and wipe the joints after use so mould struggles to take hold.

Black mould in sealant isn’t just unsightly; it shows moisture is getting in. An early reseal keeps water where it belongs.

Your questions about bath resealing in Llanarth

What does bath resealing cost?

Because every job differs, we price from pictures. You know the full cost before anything is booked.

Which areas do you work in?

We cover the entire UK, including Llanarth and the rest of Monmouthshire. Send your postcode with your photos and we’ll confirm dates.

How long does a reseal take?

A bath or shower normally takes a couple of hours. Leave it to cure before use.

Do you work for landlords and businesses?

We do, regularly. We can quote for several properties together and work between tenancies.

Do you seal over the old sealant?

We always remove the old sealant completely. Fresh silicone does not stick to old.

When can you do it?

It depends on the time of year and where you are. Send photos with your postcode and we will reply with the earliest dates.

Why does the silicone keep cracking?

The bath or tray is probably flexing. If it keeps happening, the support may need fixing.

Is there a guarantee?

Yes, for a year. If anything goes wrong with the repair within the year, we return to fix it.

Repairs by material

Shower trays

Trays are sealed with weight on them, for the same reason.

Sinks and worktops

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

What we do, step by step

We turn up when we said we would and looks over the damage before anything else. The floor and nearby surfaces are covered before we open a single tin. The work itself takes a couple of hours, and we leave the room as we found it.

  1. We cut out and remove all of the old sealant.
  2. The joint is cleaned and any mould treated.
  3. We dry the joint thoroughly.
  4. For a bath, we fill it with water first so the joint is at its widest.
  5. We run a new bead of mould-resistant silicone and smooth it neatly, taps included.

Getting ready for the visit

  • Clear the area around the damage
  • Avoid using the area for a few hours before we arrive
  • Mention any parking restrictions or tricky access

Ask for a price

Send us a photo of the damage and a wider shot of the whole item, with your NP15 postcode, and we’ll come back with a fixed quote.

Common problems we fix in Llanarth

Black mould is the most common reason people reseal. It grows into the silicone, so cleaning only removes the surface.

The things customers generally mention when they call are:

  • Discoloured, yellow sealant
  • An untidy old seal
  • Water getting behind the bath or tray
  • Silicone coming away from the tiles

What your quote should include

  • What protection goes down before work starts
  • When it can be used again
  • How the colour is matched
  • What aftercare is recommended

Our hiring checklist

When a repair is not the answer

We would rather lose a job than do one that will not last, so here’s what a repair can’t put right:

  • Hidden water damage
  • Hollow or loose tiles
  • Gaps so wide they need filling or trims before sealing

Send us pictures and we’ll tell you honestly before booking.
