Bath resealing near Dinas Powys

Bath resealing at your home in Dinas Powys

Resealing is one of the simplest ways to protect your bathroom. Failed sealant lets water get where it shouldn’t, and a new seal stops it. Common call-outs are for old sealant that looks dirty and gaps in the seal, on basins & vanity units, baths and shower trays & enclosures.

The work is guaranteed for twelve months. If something is not right in that time, we come back and put it right.

How to look after the repair

Once the work has cured, treat it gently:

  • Dry the seal after bathing
  • Open a window after bathing
  • Do not stand toiletries on the seal
  • Run the extractor fan during and after showers

Leave the sealant to cure for the time we give you, normally about a day.

Black mould in sealant is not just unsightly. Resealing early keeps water out of the walls and floor.

What we do, step by step

We agree an arrival time beforehand. On site, it takes a couple of hours for most jobs. The room is left tidy and ready to use once it has cured.

  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. The bead is smoothed, the tape removed and the seal left to cure.

Before we arrive

  • Let the surface dry out before the visit
  • Have somewhere for us to park nearby if possible
  • Tell us about parking, stairs or access

Choosing a repair company

What bath resealing costs

We don’t charge extra for travel to Dinas Powys. The price depends on:

  • Where the damage is and how we get to it
  • The material
  • How hard the colour is to match
  • The type of damage

Instead of hourly rates, we price the whole job up front. It depends on the damage, the material and access, and doing several items at once reduces it.

Send pictures for a quote

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

  • One picture of the entire bath or shower
  • What it’s made of, if you know
  • Good light, ideally daylight, without flash glare
  • A coin beside the damage so we can judge size

There is no need for us to visit first. Nearly every job can be priced from photos: we need a close-up, a wider picture and your postcode, and we will come back to you with a fixed figure.

DIY kit or professional repair?

It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is generally cheaper.

A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.
