Bath resealing in White Cross, done in place

A good reseal is all about preparation: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, in a neat, continuous bead. We work on baths, kitchen worktops & sinks and basins & vanity units, and the jobs we see most are black spots in the silicone and missing sealant behind the taps.

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

Materials and what they mean for the repair

Sinks and worktops

We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.

Shower trays

We put weight on a tray before sealing it, so the joint is at its widest.

Aftercare tips

Simple care helps the repair last. We recommend:

  • Let steam out after showers
  • Run the extractor fan during and after showers
  • Dry the seal after bathing
  • Replace the seal when mould sets in

Good ventilation is the best protection, and dry the joints after bathing to keep mould away.

Damp below or loose tiles need checking quickly. There may be more going on, and we will say if you need a builder or plumber.

Do you need bath resealing in White Cross?

A bathroom without good ventilation is hard on sealant: moisture sits on the joints longer, and mould takes hold.

Typical reasons for a call-out include:

  • A messy previous reseal
  • Gaps in the seal
  • Black spots in the silicone
  • Discoloured, yellow sealant

Questions to ask before booking

  • When it can be used again
  • How the room is protected while they work
  • If travel is included in the price
  • Is the price fixed, and does it include VAT?

10 questions to ask before you book

Honest limits

Honesty matters more than a booking, so here’s what a repair won’t do:

  • Very wide gaps that need a trim
  • Rotten walls or floors behind the bath
  • A bath or tray that moves, until its support is fixed

Send us photos and we will tell you honestly.

Surfaces we repair

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

What we do, step by step

Expect a friendly, tidy visit. We confirm the time with you beforehand, protect the area, then carry out the work, which generally takes a couple of hours. If anything looks different from your photos, we will talk to you before going ahead.

  1. We cut out and remove all of the old sealant.
  2. The joint is cleaned and any mould treated.
  3. We dry the joint 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.

Preparing for the visit

  • Let us know if it has been repaired before
  • Let us know about parking or access
  • Ensure the area is dry

Resealing in White Cross: why it matters

Resealing costs very little and protects the walls and floor. Failed sealant can lead to water damage that is much more expensive. We do not add extras on the day. What we quote from your photos is what you pay, unless the damage turns out to be different, in which case we talk to you first.

What you get with us

  • We come to you, anywhere in the UK
  • Accredited with CHAS, Constructionline and SafeContractor
  • We leave the room as we found it
  • No extra charge for your area

See our full price list.

Should I try a DIY kit first?

A DIY attempt isn’t a disaster. We remove the old filler and start again, so it does not stop a professional repair. Just mention it when you send pictures, as it can add time.

The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.

Your questions about bath resealing in White Cross

Can I get a quote without a visit?

Yes, almost always. A close-up and a wider photo are enough to give a fixed quote.

Do you work for landlords and businesses?

Yes. We carry out repairs for homeowners, landlords, letting agents, builders and businesses in White Cross.

How do I stop mould in sealant?

Mould needs moisture. Ventilation and drying keep it clean longer.

What happens if you find more damage?

If we find something the pictures didn’t show, we explain it first. The price only changes if you agree.

Are you a vetted contractor?

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

Can you repair something that’s been repaired before?

Most of the time. Tell us what was done before and we will plan for it.

Are there extra charges for White Cross?

We don’t add a call-out fee. Your fixed price includes everything.

Is there any odour?

A little, depending on the job. Open windows and an extractor fan help.

For landlords and businesses

Rental properties take more wear, and replacing things at every changeover adds up. Repairing between tenants keeps the property presentable for less.

Letting agents often send us photos straight from the inventory. That means we can quote before you even visit the property, and we liaise with tenants about access if you’d like us to.
