Resealing in Heath: why it matters

Resealing is routine maintenance. Putting off a reseal lets water get behind the bath or tray, and that damage costs much more to fix. Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Send pictures and we will give you the exact figure.

Bath resealing in Heath without replacing anything

The key to a good reseal is getting all of the old silicone out. Fresh sealant does not stick to old, which is why many DIY jobs peel. Our repair technicians work on baths, basins & vanity units and shower trays & enclosures, and people most often call us about gaps by the taps and discoloured, yellow sealant.

All our work is covered by a one-year guarantee, wherever you are in Cardiff.

Aftercare tips

After the repair has cured, a few habits help it last:

  • Replace the seal when mould sets in
  • Store bottles on a shelf
  • Clean the sealant gently and regularly
  • Let steam out after showers

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

Reseal before water gets in. Gaps or lifting edges mean it needs doing.

Materials and what they mean for the repair

Shower trays

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

Baths

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

Our hiring checklist

Heath: your questions answered

When can you do it?

Your quote comes with available dates. Tell us if you need it done quickly.

What does bath resealing cost?

Because every job differs, we price from photos. You will get a fixed figure before you book.

Is it OK to have pets in the house?

Yes, as long as they stay out of the room we’re working in. We will tell you when the room can be used again.

Does someone need to be in?

Someone needs to let us in and show us the job. You don’t need to watch us work.

What happens next?

We review the pictures and send a fixed quote and the next dates we have.

Why does mould come back so fast?

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

What do you need from me?

Just pictures, your postcode and a contact number. On the day, access to the room.

Can you repair several things at once?

Yes. Combining jobs on one visit brings the cost down. Include photos of each item.

DIY kit or professional repair?

For a hairline mark somewhere you will never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, a professional repair is worth it.

If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it will not stop us repairing it. It does add a little time, so tell us about it when you send pictures.

What we do, step by step

On the day, we arrive at the time we’ve agreed, cover the area with dust sheets and masking, and set to work. Expect it to take around two hours. We clean up when we’re done and let you know when you can use it again.

  1. We cut out and remove all of the old sealant.
  2. Next we clean the joint and deal with mould.
  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.

Getting ready for the visit

  • Keep a parking space free if you can
  • Clear the area around the damage
  • Avoid using the area for a few hours before we arrive

Getting a price

Pricing is simple: take a close-up of the damage and a photo from further back, send them to us with your postcode, and we will reply with a fixed price. There is no charge for the quote and no obligation.

Advice

What we cannot put right

A repair is not always the answer, and we’ll tell you before we start. We cannot fix:

  • Loose tiles, which need refixing first
  • A flexing bath
  • Gaps too big for silicone alone

Send us pictures and we’ll tell you honestly before you book.

Materials we work on in Heath

  • Shower trays & enclosures
  • Basins & vanity units

Prices and what affects them

There are no hourly rates or hidden extras. The price depends on:

  • The colour and finish to match
  • The type of damage
  • How many items we do on one visit
  • What the surface is made of

The price reflects the work involved, not where you live. You will see the full price before booking, with nothing added on the day.

Send pictures for a quote

Photographing the damage takes a minute, and it saves a visit. Try to send:

  • Natural light rather than flash
  • Where you are, by postcode
  • One sharp close-up of the damage
  • Any earlier repairs or coatings

The quickest way to a price is to send a couple of pictures using our quote form or ring us. We will say right away if a repair is the right fix.
