How we handle bath resealing in Magor

A good reseal is all about preparation: every bit of old silicone out, mould treated, the joint clean and dry. Then the fresh sealant goes on, as one neat, continuous bead. Common call-outs are for silicone smeared on tiles and black mould in the sealant, across shower trays & enclosures, wet rooms and basins & vanity units.

A one-year guarantee comes as standard.

Landlords, agents and businesses in Magor

Builders, developers and site managers book us for snagging repairs, putting right damage done during fitting. We hold CHAS, Constructionline and SafeContractor accreditations.

We are used to working with agents and managing companies. Just send pictures, the address and how to get access and we’ll handle the rest.

The process

When we visit, we arrive at the time we have agreed, cover the area with dust sheets and masking, and set to work. Expect it to take a couple of hours. We tidy up before we leave and tell you when it’s ready to use.

  1. We cut out all of the old sealant.
  2. Residue is removed and the joint cleaned.
  3. We treat mould and dry the joint thoroughly.
  4. The bath is filled with water, or weight put on the tray.
  5. We apply fresh mould-resistant silicone and tool a neat bead.

How to prepare

  • Clear toiletries, mats and anything else from around the area
  • Have a window or extractor fan available
  • Let us know about parking or access

When we’d advise against a repair

We won’t take on work that won’t last, so these are the limits:

  • Very wide gaps that need a trim
  • A flexing bath
  • Loose tiles, which need refixing first

Send us pictures and we will tell you honestly.

Materials we repair

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

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. Every job is a little different, so we price each one individually. The size and type of damage, the material and access all play a part, and combining jobs on one visit brings the cost down.

Why book with us

  • CHAS, Constructionline and SafeContractor accredited
  • No extra charge for your area
  • A fixed quote before you book
  • We will tell you if it’s not worth repairing

How to look after the repair

Most damage we see is avoidable. A few tips:

  • Clean the joints with a mild cleaner
  • Run the extractor fan during and after showers
  • Store bottles on a shelf
  • Reseal at the first sign of lifting

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

Black mould in sealant is not just unsightly. Resealing early keeps water out of the walls and floor.

FAQs for Magor

How do I get a price for bath resealing in Magor?

The exact price depends on the damage, so we quote from photos. You know the full cost before anything is booked.

Why does my sealant keep going mouldy?

Generally poor ventilation and moisture sitting on the joint. Mould-resistant silicone and good ventilation help.

Can you reseal over the old silicone?

We always remove the old sealant completely. New silicone won’t bond to old.

Why does the silicone keep cracking?

Normally because the bath or tray moves, or it was sealed with the bath empty. We fill the bath before sealing it.

It’s been repaired before. Can you still fix it?

Normally, yes. The old repair comes out first, so let us know about it.

Is a repair better than a new one?

Usually, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. If replacing would be better, we will say so.

How soon can you come?

We’ll give you dates with your quote. Tell us if you need it done quickly.

I rent my home. Can I book you?

Yes. Ask your landlord first, and we can send them the quote if that helps.

Should I try a DIY kit first?

DIY kits are sold for most surfaces, and they can make a small mark look better. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.

What a professional repair adds is preparation, colour matching and finishing. 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.

Different materials, different repairs

Shower trays

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

Sinks and worktops

We reseal basins, vanity tops and kitchen worktops, once the joint is completely dry.

Common problems we fix in Magor

Sealant does not last forever. Each shower leaves moisture and soap behind, which mould loves, and the joint moves slightly every time the bath is filled.

Most people get in touch when they notice one of these:

  • Unsealed corners
  • Discoloured, yellow sealant
  • Sealant that is split or lifting
  • An untidy old seal
