About our bath resealing in Glan-llyn

A reseal is a small job that makes a big difference. Clean, white joints make a bathroom look cared for, and they keep water out. If you are dealing with missing sealant behind the taps and sealant that’s split or lifting, we can typically put it right, on wet rooms, shower trays & enclosures and basins & vanity units alike.

A one-year guarantee comes with the work, just as it does everywhere we cover.

What a repair cannot fix

It helps to know what we cannot do too:

  • Movement in the bath or tray
  • Tiles that move, until they’re refixed
  • Water damage behind the bath that needs a builder

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

Materials we repair

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

How to care for the repair

Nothing complicated is needed:

  • Dry the seal after bathing
  • Do not stand toiletries on the seal
  • Use the extractor fan
  • Clean the sealant gently and regularly

Keep the room well ventilated, and dry the joints after bathing to keep mould away.

Do not wait until water gets behind the bath. Gaps or lifting edges mean it needs doing.

What bath resealing costs

There is no charge for travel to Glan-llyn. The price comes down to:

  • Any earlier repairs that need removing first
  • What the surface is made of
  • Unusual colours or finishes
  • How much damage there is

What it costs depends on the type and amount of damage, the material and how many jobs we combine into one visit. We give a fixed price from your photos, so there are no surprises on the day.

Quotes from your pictures

Before you send photos, these tips help us give you a firm price:

  • Good light, ideally daylight, without flash glare
  • Details of any past repairs
  • What it’s made of, if you know
  • A coin or ruler next to the damage for scale

To get a price, send a couple of photos through our quote form or ring us. We’ll tell you honestly if a repair is the right fix.

Can I fix it myself?

A kit can be fine for a tiny mark out of sight. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, it’s worth having it done properly.

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 the old filler has to come out before a proper repair.

For landlords and businesses

Rented homes see more wear and tear, and replacing items every time a tenant leaves is expensive. Repairing between tenants keeps the property presentable for less.

Hotels, guest houses and holiday lets need rooms back in use quickly, so most of our work is done in a single visit. We will fit around changeovers where we can.

What we do, step by step

We turn up when we said we would and checks the damage against your pictures first. The floor and nearby surfaces are covered before any work starts. Most visits take a couple of hours, and we leave the room as we found it.

  1. First we strip out every bit of the old mastic.
  2. We clean the joint and treat any mould.
  3. The joint is dried 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.

How to prepare

  • Open a window if you can
  • Avoid using the area for a few hours before we arrive
  • Mention any earlier repairs or resurfacing
