Trusted bath resealing in Llwyncelyn

Bath resealing in Llwyncelyn, done in place

All of the old sealant is cut out, deal with any mould, and reseal with new mould-resistant silicone. We do this for baths, showers, sinks and worktops, including the awkward bits behind the taps. We regularly repair basins & vanity units, kitchen worktops & sinks and shower trays & enclosures, and the jobs we see most are a messy previous reseal and leaks at the edges.

All of our repairs are guaranteed for twelve months, and the guarantee is the same wherever you live. If something goes wrong with the work, we come back.

Questions from Llwyncelyn

How long will it take?

Around two hours for a bath, then it needs to cure.

Are you a vetted contractor?

We are accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.

Will you leave a mess?

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

Is it OK to have pets in the house?

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?

Some materials have a smell while they’re applied, which is why we ventilate. It clears as the materials cure.

My seal keeps tearing. Why?

Movement is the usual cause. We seal baths full of water.

Do you charge for travel?

No. Our quotes include travel, and we charge the same wherever you are.

Why does mould come back so fast?

Mostly moisture and poor ventilation. Mould-resistant silicone and good ventilation help.

Different materials, different repairs

Sinks and worktops

Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.

Shower trays

We put weight on a tray before sealing it, for the same reason.

How the visit 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 job takes a couple of hours, and we finish with a tidy-up and a look at the finished work together.

  1. We cut out all of the old sealant.
  2. We remove the residue and clean the joint.
  3. We treat mould and dry the joint thoroughly.
  4. We fill the bath, or weight the tray, to open the joint.
  5. We apply fresh mould-resistant silicone and tool a neat bead.

Before we arrive

  • Mention any parking restrictions or tricky access
  • Move bottles, mats and clutter away from the area
  • Keep children and pets away from the room on the day

What we’re called out for in Llwyncelyn

Even good sealant eventually discolours particularly in a well-used bathroom. Steam, soap and movement all take their toll.

Send us a photo if you notice any of these:

  • Leaks at the edges
  • Black mould in the sealant
  • Old sealant that looks dirty
  • Silicone smeared on tiles

What to look for in a quote

Our hiring checklist

When a repair is not the answer

Some problems need a builder, plumber or fitter rather than us:

  • Movement in the bath or tray
  • Tiles that move, until they’re refixed
  • Gaps too big for silicone alone

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

Materials we repair

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

Prices and what affects them

We do not charge extra for travel to Llwyncelyn. The price comes down to:

  • How many items we do on one visit
  • Whether it’s a chip, crack, burn or wear
  • Previous DIY repairs that have to come out
  • How easy the damage is to reach

A repair is priced on what needs doing, not your postcode. The full price is agreed before you book.

Quotes from your photos

Photographing the damage takes a minute. Please include:

  • Something in shot to show the size
  • One sharp close-up of the damage
  • Whether it’s been repaired or coated before
  • Natural light rather than flash

For most jobs, pictures are all we need to give you a price. Tell us what happened and where you are, and we will send back a fixed quote and some dates.

Why reseal now?

Sealing over old silicone is a false economy. It soon peels, and mould stays trapped behind it. A proper reseal removes the old first. Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Photos let us give you the exact figure.

Why book with us

  • Everything repaired in place
  • Rooms protected and left tidy
  • No extra charge for your area
  • Fixed prices from your photos

See our prices page.

Work for landlords and builders

Rental properties take more wear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.

For developers and builders, we fix damage before handover, so there is no need to replace a damaged item at the last minute. We can visit several plots in one trip.

DIY kit or professional repair?

It’s tempting to reach for a kit, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Getting it right first time is generally cheaper.

We understand the appeal of fixing it yourself. The trouble is that kit repairs often look fine at first and then fail, and the old filler has to come out before a proper repair.
