How it works

From the moment we arrive, the aim is to do the job without disturbing the rest of your home. We mask off everything nearby, the work takes a couple of hours, and we finish by cleaning up and talking you through the result.

  1. The old silicone is cut out completely.
  2. Residue is removed and the joint cleaned.
  3. Any mould is treated and the joint dried.
  4. The bath is filled with water, or weight put on the tray.
  5. New mould-resistant silicone is applied and tooled neatly.

Before we arrive

Why it’s worth resealing in Astwick

A reseal is one of the cheapest bathroom jobs there is and protects the walls and floor. Failed sealant can lead to water damage that is much more expensive. Compared with replacing, repairing normally costs far less, because nothing has to be taken out, refitted or made good. The quote lists exactly what you are paying for.

Why book with us

  • CHAS and Constructionline accredited
  • We come to you, anywhere in the UK
  • No extra charge for your area
  • Honest advice, even when it means no job

Take a look at our pricing.

Should I try a DIY kit first?

If you do try a kit, read the instructions carefully, ensure the area is clean and completely dry, and give it the full curing time. If it fails, we can still put it right.

For a hairline mark somewhere you’ll never see, a kit may be enough. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.

What your bath or shower is made of matters

Baths

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

Shower trays

Trays are sealed with weight on them, for the same reason.

Astwick questions

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

Every job gets a fixed quote from your photos. Send a close-up and a picture of the entire item with your SG5 postcode.

Is it messy?

We protect the room with dust sheets and masking first, and tidy up before we leave.

Do you do work for letting agents?

Yes. We work for landlords, agents, builders and businesses as well as homeowners in Astwick.

Which areas do you work in?

Across the UK. Our prices are the same everywhere.

Can I add another job to the visit?

Of course, and it typically saves money. Just add the extra items to your pictures and you will get one combined price.

How quickly can you book me in?

We’ll give you dates with your quote. If it’s urgent, say so and we’ll do what we can.

My seal keeps tearing. Why?

Generally because the bath or tray moves. We fill the bath before sealing it.

I rent my home. Can I book you?

Yes. Ask your landlord first, and we can send them the quote if that helps.

What a repair cannot fix

In fairness, there are a few things a repair won’t fix:

  • A flexing bath
  • Hollow or loose tiles
  • Gaps so wide they need filling or trims before sealing

If in doubt, send photos and we’ll say what we think before you book.

Surfaces we repair

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

When to call us in Astwick

Even good sealant eventually discolours, especially in a busy family bathroom. Steam, soap and movement all take their toll.

People usually call us when they notice one of these:

  • An untidy old seal
  • Mould you cannot clean out
  • Old sealant that looks dirty
  • Water getting behind the bath or tray

Aftercare tips

How the surface is treated afterwards matters:

  • Air the room after use
  • Clean the sealant gently and regularly
  • Reseal at the first sign of lifting
  • Run the extractor fan during and after showers

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

Mouldy sealant is more than a cosmetic problem; it shows moisture is getting in. An early reseal keeps water where it belongs.
