About our bath resealing in Wonersh

A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and a new seal stops it. Our technicians work on baths, basins & vanity units and shower trays & enclosures, and common reasons people get in touch are unsealed corners and black spots in the silicone.

All of our repairs are guaranteed for twelve months. If something goes wrong with the work, we come back.

Our hiring checklist

Honest limits

A repair is not right for every job, for example:

  • Loose tiles, which need refixing first
  • Very wide gaps that need a trim
  • Water damage behind the bath that needs a builder

If in doubt, send pictures and we will say what we think before booking.

Materials we repair

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

How to look after the repair

Once the work has cured, treat it gently:

  • Dry the seal after bathing
  • Clean the sealant gently and regularly
  • Store bottles on a shelf
  • Run the extractor fan during and after showers

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

Black mould in sealant is not just unsightly; it shows moisture is getting in. Resealing early keeps water out of the walls and floor.

Why reseal now?

Resealing costs very little, and it protects everything around the bath. Leaving failed sealant can let water cause damage that costs far more to fix. It helps to know what pushes a price up or down: access, material, the extent of the damage and whether we can do several items together. Send pictures and you will get a fixed figure.

Prices and what affects them

You won’t pay by the hour. The price depends on:

  • The size and number of damaged areas
  • Whether old repairs or coatings need taking off
  • How easy the damage is to reach
  • How hard the colour is to match

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.

How to get a fixed quote

It only takes a minute to photograph the damage. Please include:

  • The postcode, so we can plan the visit
  • A wider photo showing the entire bath or shower
  • Any earlier repairs or coatings
  • Daylight if possible, and no flash reflection

Ring 0345 017 0787, or send us pictures through the quote form. With one close-up and one wider picture, we can give you a fixed price.

Can I fix it myself?

What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.

If you’re set on a kit, follow its instructions closely, ensure the area is clean and completely dry, and do not use it until it has fully cured. If it fails, we can still put it right.

Common questions in Wonersh

I’m a tenant. Can you help?

Yes, though it’s best to check with your landlord first. Landlords are frequently glad to have it sorted.

Can new silicone go over old?

No, we never seal over old silicone. The old sealant is cut out and the joint cleaned and dried.

What do you need from me?

A close-up, a wider photo and your postcode. After that, we just agree a date.

Are there extra charges for Wonersh?

We don’t add a call-out fee. The fixed price covers the visit and the work.

Do the materials smell?

Some materials have a smell while they’re applied. It fades as everything cures.

Do you cover Wonersh?

Yes, we do. We send a technician to Wonersh for every job, and the price is the same as everywhere else.

Can you redo someone else’s repair?

In most cases. We remove the old repair before doing a new one, so mention it when you send photos.

Is it safe with children and pets around?

On the day, the room should be kept clear of pets and children, so the repair isn’t disturbed while it cures.

How it works

On the day, the technician arrives at the agreed time, protects the room with dust sheets and masking and gets started. The job typically takes a couple of hours. We tidy up before we leave and let you know when you can use it again.

  1. First we strip out every bit of the old mastic.
  2. We clean the joint and treat any mould.
  3. We ensure the joint is completely dry.
  4. For a bath, we fill it with water first so the joint is at its widest.
  5. We apply new mould-resistant silicone and tool it to a neat finish, taps included.

How to prepare

  • Open a window if you can
  • Tell us about parking, stairs or access
  • Plan for the room to be out of bounds to pets and children
