Bath resealing near Llanvaches

Bath resealing in Llanvaches, done in place

We cut out all of the old sealant, deal with any mould, and reseal with new mould-resistant silicone. We do this for baths, showers, sinks and worktops, and that includes the awkward spots behind the taps. We work on kitchen worktops & sinks, basins & vanity units and wet rooms, and common reasons people contact us are an untidy old seal and black mould in the sealant.

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

Looking after it afterwards

Once the work has cured, treat it gently:

  • Reseal when black spots won’t clean off
  • Clean the sealant gently and regularly
  • Keep the joints dry
  • Do not stand toiletries on the seal

Leave the sealant to cure for the time we give you, normally about a day.

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.

How we price bath resealing

Each job gets its own fixed quote. These are the things that affect it:

  • Any earlier repairs that need removing first
  • Access to the area
  • The material and finish
  • Whether we combine several jobs

Rather than charging by the hour, we price the whole job up front. Damage, material and access decide it, and doing several items at once reduces it.

How to get a fixed price

Most quotes are done from pictures alone. To help us price it:

  • Whether it’s been repaired or coated before
  • A close-up of the damage, in focus
  • One picture of the entire bath or shower
  • Something in shot to show the size

To get a price, send a couple of photos using our quote form or call us. We’ll tell you honestly whether it can be repaired.

Llanvaches: your questions answered

Do you work for landlords and businesses?

We do, regularly. We can quote for several properties together and work between tenancies.

Can you quote from photos?

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

Why does the silicone keep cracking?

Something is moving. If it keeps happening, the support may need fixing.

Will it make a mess?

Dust sheets and masking go down before we start, and we clean up when we’ve finished.

What information do you need?

A close-up, a wider photo and your postcode. Then we will agree a date.

Can pets and children be at home?

Please keep children and pets out of the room during the visit and until it has cured. Everywhere else in the home is fine.

Do the materials smell?

There may be a mild smell during the work that clears as it cures.

Can you redo someone else’s repair?

Yes, regularly. Removing the old work can add time, and that’s in the quote.

Is resealing worth it?

Resealing costs very little and protects the walls and floor. Leaving failed sealant can let water cause damage that costs far more to fix. We don’t 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.

Why us?

  • Normally one visit, start to finish
  • Free fixed quotes from pictures
  • Honest advice, even when it means no job
  • No need to remove anything

Shower trays

Trays are sealed with weight on them, so the joint is at its widest.

Baths

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

What we do, step by step

You don’t need to empty the room beforehand. Everything we use comes in the van with us, lay protective sheets and start once you are happy with the plan. Most jobs take about two hours for a bath, and you can get on with other things while we’re there.

  1. We protect the area and mask the joint lines.
  2. Old sealant and residue are removed.
  3. The joint is cleaned, treated and dried.
  4. We run a continuous bead of new silicone.
  5. We smooth the bead, remove the tape and leave it to cure.

Getting ready for the visit

  • Keep children and pets away from the room on the day
  • Clear toiletries, mats and anything else from around the area
  • Avoid using the area for a few hours before we arrive

Common problems we fix in Llanvaches

Most reseals are because of black mould. It grows into the silicone, so cleaning only removes the surface.

The things customers normally mention when they call are:

  • Water getting behind the bath or tray
  • Stained silicone
  • Gaps in the seal
  • A messy previous reseal

What to look for in a quote

  • Whether they match the colour on site
  • When it can be used again
  • A fixed quote, and whether VAT is included
  • How your room will be protected

10 questions to ask before booking

Landlord and trade work in Llanvaches

Builders use us to fix snagging damage before handover. We can visit several plots in one trip to keep costs down.

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

What a repair cannot fix

Some jobs are not right for a repair, for example:

  • Movement in the bath or tray
  • Loose tiles, which need refixing first
  • Very wide gaps that need a trim

Not sure? Send photos and we’ll give you a straight answer before booking.
