Bath resealing near Penterry

Bath resealing in Penterry, done in place

A proper reseal starts with removing every trace of the old silicone. New silicone will not bond to old, which is why many DIY jobs peel. We regularly repair kitchen worktops & sinks, shower trays & enclosures and baths, and the jobs we see most are silicone smeared on tiles and gaps by the taps.

All of our repairs are guaranteed for twelve months in Penterry and everywhere else. If something goes wrong with the work, we come back.

How it works

Visits start with a quick look at the job together, so you know exactly what we are doing. After that, protection goes down around the work area and we start. Allow about two hours for a bath, and we’ll keep you posted as we go.

  1. The old silicone is cut out completely.
  2. We remove the residue and clean the joint.
  3. Any mould is treated and the joint dried.
  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.

Getting ready for the visit

  • Tell us if there are stairs or a lift
  • Mention any parking restrictions or tricky access
  • Let us know if it has been repaired before

Penterry questions

Can you do more than one item on the same visit?

Of course, and it typically saves money. Just add the extra items to your pictures and you’ll get one combined price.

Is it messy?

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

Do you work for landlords and businesses?

Yes, often. We quote for multiple addresses and fit around tenancy changeovers.

How long does resealing take?

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

Do you cover the entire of Monmouthshire?

All of Monmouthshire, and the rest of the UK. Travel is included in the price.

I rent my home. Can I book you?

Of course. Check with your landlord; we can send the quote to them too.

Why does my sealant keep going mouldy?

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

What happens after I send pictures?

We look at the photos and reply with a fixed price and some dates. If we need another angle, we will ask.

For landlords and businesses

Landlords, letting agents and housing providers in Penterry use us as well as homeowners. Repairing between tenancies keeps void periods short, and it costs much less than replacing.

Rental properties take more wear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.

What a repair cannot fix

To be straight with you, there are a few things a repair will not fix:

  • Hollow or loose tiles
  • A flexing bath
  • Water damage behind the bath that needs a builder

If in doubt, send pictures and we will say what we think before you book.

Materials we work on in Penterry

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

How to care for the repair

Much of the damage we repair could have been avoided. These habits help:

  • Replace the seal when mould sets in
  • Store bottles on a shelf
  • Keep the joints dry
  • Open a window after bathing

Keep the room well ventilated, and wipe the joints after use.

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

Prices and what affects them

We do not charge extra for travel to Penterry. The price depends on:

  • What kind of damage it is
  • The size and number of damaged areas
  • Doing more than one item at once
  • How hard the colour is to match

Set against the cost of replacement, repairing typically costs far less, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.

How to get a fixed price

Almost every job we do is priced from pictures. This is what we need:

  • A picture taken from further back
  • Daylight if possible, and no flash reflection
  • A close-up of the damage, in focus
  • A coin beside the damage so we can judge size

If you’re in Penterry and want a price, the easiest route is photos: a close-up, a wider shot and your postcode. We reply with a fixed quote and our next available dates.

Repairs by material

Sinks and worktops

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

Baths

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

Common problems we fix in Penterry

Most reseals are because of black mould. It grows into the sealant itself, so cleaning cannot get it all out.

The things clients generally mention when they call include:

  • A messy previous reseal
  • Discoloured, yellow sealant
  • Mould you cannot clean out
  • Gaps in the seal

Before you book anyone

  • When it can be used again
  • How changes to the job are handled
  • How long the guarantee is and what it covers
  • Who turns up on the day

Our hiring checklist

DIY repairs versus a professional job

If you’ve already tried a DIY fix, that is fine. We take the old repair out and do it properly, so it will not stop us repairing it. Just mention it when you send photos, as it can add time.

A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.
