Bath resealing for Pen-twyn homes

Bath resealing at your home in Pen-twyn

Baths are resealed with water in them, so the joint is at its widest, so the seal doesn’t tear when the bath is first used. Whether it’s damp near the bath and a messy previous reseal, we can help, whatever the material.

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

Signs you need bath resealing in Pen-twyn

Most reseals are because of black mould. It grows into the sealant itself, so cleaning only removes the surface.

If you can see any of these, send us a photo:

  • An untidy old seal
  • Black spots in the silicone
  • Gaps by the taps
  • Sealant that is split or lifting

What to look for in a quote

  • Is the price fixed, and does it include VAT?
  • Whether they match the colour on site
  • What aftercare is recommended
  • How long it needs to cure

Choosing a repair company

Can I fix it myself?

If you’ve already tried a DIY fix, that’s fine. We take the old repair out and do it properly, so it will not stop us repairing it. Just mention it when you send pictures, as it can add time.

A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.

Repairs by material

Baths

We fill the bath before sealing, so the joint is at its widest.

Shower trays

We put weight on a tray before sealing it, for the same reason.

What affects the price in Pen-twyn

There are no hourly rates or hidden extras. The price depends on:

  • Doing more than one item at once
  • What the surface is made of
  • Unusual colours or finishes
  • How many areas need work

Compared with replacing, repairing usually costs far less, because nothing has to be taken out, refitted or made good. The quote lists exactly what you are paying for.

Quotes from your pictures

You can usually get a fixed price without us visiting. To help us price it:

  • A photo taken from further back
  • A coin or ruler next to the damage for scale
  • Daylight if possible, and no flash reflection
  • Any details about the material

Most customers in Pen-twyn get their price from photos. Add a line about what happened and your postcode, and we will reply with a fixed quote and the earliest dates we have.

How to care for the repair

How the surface is treated afterwards matters:

  • Store bottles on a shelf
  • Clean the sealant gently and regularly
  • Reseal at the first sign of lifting
  • Dry the seal after bathing

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

Don’t wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.

What happens on the day

Arrival times are agreed in advance. Once we’re there, the work takes about two hours for a bath for most jobs. The room is left tidy and ready to use once it has cured.

  1. The old silicone is cut out completely.
  2. We remove the residue and clean the joint.
  3. Any mould is treated and the joint dried.
  4. The bath is filled with water, or weight put on the tray.
  5. We apply fresh mould-resistant silicone and tool a neat bead.

How to prepare

  • Mention any parking restrictions or tricky access
  • Point us to the nearest place to park
  • Open a window if you can

Pen-twyn: your questions answered

Do you hold any accreditations?

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

Can you price it without visiting?

Typically, yes. Clear photos let us give you a fixed quote without visiting.

Why does my sealant keep going mouldy?

Damp is the cause. Ventilation and drying keep it clean longer.

Can pets and children be at home?

Please keep children and pets out of the room during the visit. The rest of the house is unaffected.

Are there extra charges for Pen-twyn?

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

What happens after I send photos?

We come back with a fixed price, plus dates. You are under no obligation.

Can tenants book a repair?

Yes, but check with your landlord or agent first. Many landlords are happy for a repair to be arranged before the end of a tenancy.

Do I have to be there?

Yes. The technician needs access to the room for the visit, at a time that suits you.
