Bath resealing in Llantrisant Fawr

Bath resealing in Llantrisant Fawr, done in place

Baths are resealed with water in them, so the joint opens fully, which stops the new seal tearing the first time the bath is used. Typical jobs include gaps by the taps and gaps in the seal, on kitchen worktops & sinks, baths and wet rooms.

The work is covered for a year after we finish. If anything isn’t right, ring us and we’ll come back.

Landlord and trade work in Llantrisant Fawr

Rental properties take more wear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.

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

Llantrisant Fawr questions

Will it make a mess?

Very little mess: we sheet and mask everything nearby, and we take our waste away with us.

Are you a vetted contractor?

Yes. Our accreditations include CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.

Do you work for landlords and businesses?

We do, regularly. We quote for multiple addresses and fit around tenancy changeovers.

How long does resealing take?

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

Can I get a quote without a visit?

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

How do I stop mould in sealant?

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

Can you redo someone else’s repair?

Yes, regularly. Removing the old work can add time, and that is in the quote.

What does bath resealing cost?

Every job gets a fixed quote from your pictures. Send a close-up of the damage and a wider photo with your NP15 postcode.

Is resealing worth it?

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. No two jobs are quite the same, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all make a difference, and combining jobs on one visit brings the cost down.

What you get with us

  • A fixed quote before booking
  • Honest advice, even when it means no job
  • One visit for most repairs
  • Same prices wherever you are

Should I try a DIY kit first?

You can buy a DIY kit for most repairs, and they can make a small mark look better. The trouble is colour and preparation: they come in a handful of shades, and if the surface isn’t prepared the repair won’t last.

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

How we price bath resealing

We do not charge extra for travel to Llantrisant Fawr. The price depends on:

  • The type of damage
  • What the surface is made of
  • Any earlier repairs that need removing first
  • How easy the damage is to reach

Compared with replacing, repairing usually costs far less, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.

How to get a fixed price

Most quotes are done from pictures alone. To help us price it:

  • One picture of the entire bath or shower
  • A clear, close picture of the problem area
  • Whether it’s been repaired or coated before
  • Your postcode, so we can check dates

For most jobs, pictures are all we need to give you a price. Add a line about what happened and your postcode, and we’ll reply with a fixed quote and the earliest dates we have.

How to care for the repair

Simple care helps the repair last. Our advice:

  • Keep the joints dry
  • Use the extractor fan
  • Air the room after use
  • Keep bottles off the joints

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

Reseal before water gets in. Split or lifting sealant is a sign it’s time.

What we are called out for in Llantrisant Fawr

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

Signs it’s time to call us include:

  • Gaps in the seal
  • Damp near the bath
  • A messy previous reseal
  • Black spots in the silicone

What to look for in a quote

  • When it can be used again
  • What preparation is included
  • What happens if they find more damage
  • Whether they match the colour on site

How to compare quotes

Honest limits

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

  • Movement in the bath or tray
  • Gaps so wide they need filling or trims before sealing
  • Hidden water damage

If in doubt, send photos and we’ll say what we think before you book.

Surfaces we repair

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

What happens on the day

We begin by going over the job with you. After that, protection goes down around the work area and we start. Allow a couple of hours.

  1. All the old sealant is cut out and removed.
  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, taps included.

Preparing for the visit

  • Clear the area around the damage
  • Tell us about parking, stairs or access
  • Ensure the area is dry
