About our bath resealing in Penyrheol

A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and resealing puts a stop to that. Typical jobs include black mould in the sealant and leaks at the edges, on kitchen worktops & sinks, baths and basins & vanity units.

The work is guaranteed for twelve months. If there is a problem with the repair within the year, we return and sort it.

When we would advise against a repair

We will always be straight with you, so here’s what a repair won’t do:

  • Very wide gaps that need a trim
  • Hidden water damage
  • Hollow or loose tiles

If in doubt, send pictures and we’ll say what we think.

Surfaces we repair

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

Work for landlords and builders

We carry out planned and one-off repairs for housing associations and facilities teams in Swansea and across the UK. Repairing in place avoids the disruption of a replacement, which is easier on the people living there.

Hospitality businesses need rooms back in use quickly, so we keep visits short and tidy. We can work around your bookings.

DIY kit or professional repair?

If you do try a kit, read the instructions carefully and work on a clean, dry surface, and do not use it until it has fully cured. If it fails, we can still put it right.

If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it does not stop a professional repair. Just mention it when you send photos, as it can add time.

Signs you need bath resealing in Penyrheol

Even good sealant eventually discolours particularly in a well-used bathroom. Steam, soap and movement all take their toll.

  • Missing sealant behind the taps

What to look for in a quote

  • Whether there are any call-out or travel charges

How to compare quotes

Different materials, different repairs

Baths

Baths are resealed with water in them, to open the joint fully.

Sinks and worktops

Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.

How the visit works

The work is clean and fairly quiet, so you can carry on at home. We protect the area first, then the work takes about two hours for a bath. At the end we talk you through how soon it can be used and how to look after it.

  1. We cut out and remove all of the old sealant.
  2. Next we clean the joint and deal with mould.
  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, including around the taps.

Preparing for the visit

  • Move bottles, mats and clutter away from the area
  • Mention if the room is upstairs or in a flat
  • Have a window or extractor fan available

How to get a price

There’s no need for us to visit first. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll come back to you with a fixed figure.

Keeping it looking good

Good habits make a big difference to how long a repair lasts. Here’s what we suggest:

  • Don’t stand toiletries on the seal
  • Open a window after bathing
  • Replace the seal when mould sets in
  • Run the extractor fan during and after showers

Run the extractor fan, wipe the joints dry after use, and give them a regular clean with a mild cleaner to slow mould growth.

Damp below or loose tiles need checking quickly. It may be more than a reseal, and we’ll say if you need a builder or plumber.

Common questions in Penyrheol

How do I book?

Use the quote form or ring 0345 017 0787.

What areas do you cover?

We cover the whole UK, including Penyrheol and the rest of Swansea. Send your postcode with your photos and we will confirm dates.

Do you work in Penyrheol?

Yes. We work across the UK and travel to Penyrheol and the rest of Swansea. Send photos and we’ll quote, or call 0345 017 0787.

How long before I can shower?

You’ll get the curing time from us, normally around a day.

I’m a tenant. Can you help?

Yes. Ask your landlord first, and we can send them the quote if that helps.

Why does my sealant keep going mouldy?

Mould needs moisture. Run the fan, dry the joints and the new seal stays cleaner for longer.

What happens after I send pictures?

You will get a fixed quote back. There is no obligation to book.

Can I get a quote without a visit?

Yes, almost always. A close-up and a wider photo are enough to give a fixed quote.

Why it’s worth resealing in Penyrheol

Sealing over old silicone is a false economy. It peels within weeks, and mould stays trapped behind it. A proper reseal removes the old first. There are no surprise extras on the day. The price we quote from your pictures is the price you pay, unless the damage turns out to be different, in which case we talk to you first.
