Bath resealing at your home in Llwyncelyn

A good reseal is all about preparation: old silicone removed, mould treated, the joint cleaned and dried. Only then does the new sealant go on, in a neat, continuous bead. Common call-outs are for gaps in the seal and missing sealant behind the taps, on shower trays & enclosures, kitchen worktops & sinks and wet rooms.

Whatever the size of the job, you get the same one-year guarantee in Llwyncelyn and across Rhondda Cynon Taff.

How to look after the repair

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

  • Keep the joints dry
  • Open a window after bathing
  • Clean the sealant gently and regularly
  • Use the extractor fan

Use the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.

Don’t wait until water gets behind the bath. Gaps or lifting edges mean it needs doing.

When a repair is not the answer

A few problems are outside what a surface repair can do:

  • Hidden water damage
  • A bath or tray that moves, until its support is fixed
  • Gaps too big for silicone alone

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

Materials we repair

  • Kitchen worktops & sinks

DIY repairs versus a professional job

It’s natural to want to try a repair yourself. The trouble is that kit repairs often look fine at first and then fail, and then the old filler has to be removed first.

DIY kits are sold for most surfaces, 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 is not prepared the repair won’t last.

Why it’s worth resealing in Llwyncelyn

Putting new silicone over old does not last. It soon peels, and traps mould underneath. We remove the old sealant completely. A few things move the price: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.

What you get with us

  • No need to remove anything
  • Repair technicians who travel to you, UK-wide
  • CHAS and Constructionline accredited
  • Fixed prices from your photos

Do you work in Llwyncelyn?

What happens next?

Will it make a mess?

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

Why does mould come back so fast?

Mostly moisture and poor ventilation. Mould-resistant silicone and good ventilation help.

  • Old sealant that looks dirty
  • Damp near the bath
  • Silicone smeared on tiles
  • Sealant that is split or lifting

Choosing a repair company

The process

When we visit, the technician arrives at the agreed time, protects the room with dust sheets and masking and gets started. Expect it to take about two hours for a bath. We tidy up before we leave and let you know when you can use it again.

  1. The surrounding area is protected and the joints masked.
  2. We remove the old sealant and every trace of residue.
  3. We clean, treat and dry the joint.
  4. Fresh silicone is applied in a continuous bead.
  5. We smooth the bead, remove the tape and leave it to cure.

Preparing for the visit

  • Mention any earlier repairs or resurfacing
  • Keep pets and children out of the room while we work
  • Avoid using the area for a few hours before we arrive
