Trusted bath resealing in Killay

Keeping it looking good

So the finish stays in good condition:

  • Don’t stand toiletries on the seal
  • Run the extractor fan during and after showers
  • Clean the joints with a mild cleaner
  • Replace the seal when mould sets in

Avoid scraping the joints, and keep shampoo bottles off the joints.

Reseal before water gets in. Gaps or lifting edges mean it needs doing.

How we handle bath resealing in Killay

Preparation is everything in a reseal: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, in a neat, continuous bead. We regularly repair baths, wet rooms and shower trays & enclosures, and the jobs we see most are unsealed corners and gaps in the seal.

We guarantee the work for a year. If there is a problem with the repair within the year, we return and sort it.

Why it’s worth resealing in Killay

A reseal is one of the cheapest bathroom jobs there is, and it protects everything around the bath. Leaving failed sealant can let water cause damage that costs far more to fix. A repair normally costs much less than people expect, particularly next to the cost of replacement. Send photos and we’ll give you the exact figure.

Killay questions

It’s been repaired before. Can you still fix it?

Yes, we frequently do. It can add a little time, which we include in the quote.

Do you work in Killay?

Yes. We cover the entire UK and come to Killay and the rest of Swansea. Send us pictures for a fixed quote, or call 0345 017 0787.

How do I get a price for bath resealing in Killay?

The exact price depends on the damage, so we quote from pictures. You know the full cost before anything is booked.

Are you accredited?

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

What information do you need?

Photos of the damage, a picture of the whole bath or shower and your postcode. Then we’ll agree a date.

Can landlords book you?

Yes. We work for landlords, agents, builders and businesses as well as householders in Killay.

Is there a call-out fee?

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

Will you leave a mess?

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

DIY kit or professional repair?

What a professional repair adds is preparation, colour matching and finishing. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, and the work is guaranteed.

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.

The process

Your technician turns up when we said we would and checks the damage against your photos first. Dust sheets and masking tape go down before any work starts. Most visits take around two hours, and the room is left clean and tidy.

  1. All the old sealant is cut out and removed.
  2. The joint is cleaned and any mould treated.
  3. We dry the joint thoroughly.
  4. Baths are filled 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

  • Plan for the room to be out of bounds to pets and children
  • Tell us about any previous repairs or coatings
  • Have somewhere for us to park nearby if possible

How to get a price

Getting a price is easy: snap the damage close up and then the entire item, send them to us with your postcode, and you will get a fixed quote back. Quotes are free and you are under no obligation.

Prices and what affects them

We price every job individually, from your pictures. The main factors are:

  • How much damage there is
  • The colour and finish to match
  • Previous DIY repairs that have to come out
  • How easy the damage is to reach

Rather than charging by the hour, we price the entire job up front. Damage, material and access decide it, and combining items on one visit brings it down.

Getting a price from photos

A couple of clear pictures is all it takes. It helps if you send:

  • Any details about the material
  • Any earlier repairs or coatings
  • A coin beside the damage so we can judge size
  • The postcode, so we can plan the visit

For a price in Killay, the easiest route is pictures: a close-up, a wider shot and your postcode. You will get a fixed quote with dates to choose from.
