Bath resealing for Llanhilleth homes

Bath resealing in Llanhilleth without replacing anything

All of the old sealant is cut out, treat any mould, and apply fresh mould-resistant silicone. We do this for baths, showers, sinks and worktops, including the awkward bits behind the taps. Typical jobs include a messy previous reseal and sealant that’s split or lifting, across wet rooms, basins & vanity units and shower trays & enclosures.

We stand behind the work with a one-year guarantee, so you are covered after the visit.

Aftercare tips

How the surface is treated afterwards matters:

  • Ventilate the bathroom well
  • Air the room after use
  • Wipe the joints dry after use
  • Give the seal a regular clean

Do not scrape the sealant with anything sharp, and do not stand bottles on the seal.

Reseal before water gets in. Gaps or lifting edges mean it needs doing.

Common questions in Llanhilleth

Does someone need to be in?

We need someone to let us in. After that, you can carry on with your day.

I’m a tenant. Can you help?

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

Do you cover the whole of Blaenau Gwent?

The entire UK, including all of Blaenau Gwent. Just include your postcode and we will confirm dates.

Can pets and children be at home?

On the day, the room should be kept clear of pets and children, so the repair isn’t disturbed while it cures.

Can you repair several things at once?

Of course, and it normally saves money. Send pictures of everything together and we will quote them together.

Will you leave a mess?

We protect the room with dust sheets and masking first, and we clean up when we’ve finished.

Why does mould come back so fast?

Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.

Are there extra charges for Llanhilleth?

Travel is included in the price, with the same prices everywhere we work.

DIY repairs versus a professional job

Kits are cheap and easy to find, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Doing it properly first is usually the cheaper route.

What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.

What bath resealing costs

We charge the same across the UK, including Llanhilleth. The price reflects:

  • Doing more than one item at once
  • What the surface is made of
  • What kind of damage it is
  • How hard the colour is to match

It helps to know what pushes a price up or down: access, material, the extent of the damage and whether we can do several items together. Photos let us give you a fixed figure.

Getting a price from pictures

Two or three clear pictures are usually enough. It helps if you send:

  • The material, if you know it
  • One sharp close-up of the damage
  • Something in shot to show the size
  • Any earlier repairs or coatings

No survey visit is needed: we price from photos. Use the quote form, or ring 0345 017 0787 to talk it through, and we’ll come back with a fixed figure.

When to call us in Llanhilleth

No sealant lasts for ever. Each shower leaves moisture and soap behind, which mould loves, and the joint moves slightly every time the bath is filled.

These are the problems we’re asked about most:

  • Gaps in the seal
  • An untidy old seal
  • Black mould in the sealant
  • Unsealed corners

Before you book anyone

  • What aftercare is recommended
  • What happens if the damage is worse than the pictures show
  • If travel is included in the price
  • Whether the colour is mixed to match

What a repair cannot fix

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

  • Gaps so wide they need filling or trims before sealing
  • Water damage behind the bath that needs a builder
  • A flexing bath

Send us pictures and we will tell you honestly before you book.

Surfaces we repair

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

How the visit works

Visits start with a quick look at the job together, so you know exactly what we’re doing. Then the area is sheeted and masked and we start. You can expect it to take about two hours for a bath, and we’ll tell you if anything changes.

  1. We protect the area and mask the joint lines.
  2. Old sealant and residue are removed.
  3. The joint is cleaned, treated and dried.
  4. Fresh silicone is applied in a continuous bead.
  5. We smooth the bead, remove the tape and leave it to cure.

How to prepare

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

Ask for a price

Email us a picture of the damage and a wider shot of the entire item, with your NP13 postcode, and we will come back with a fixed quote.
