When we would advise against a repair

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

  • A bath or tray that moves, until its support is fixed
  • Gaps too big for silicone alone
  • Water damage behind the bath that needs a builder

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

What we work on

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

Materials and what they mean for the repair

Baths

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

Sinks and worktops

We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.

For landlords and businesses

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

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.

What we do, step by step

Expect a friendly, tidy visit. We confirm the time with you beforehand, protect the area, then carry out the work, which typically takes a couple of hours. If we find something your pictures didn’t show, we will explain it before carrying on.

  1. We cut out all of the old sealant.
  2. Residue is removed and the joint cleaned.
  3. Any mould is treated and the joint dried.
  4. The bath is filled with water, or weight put on the tray.
  5. New mould-resistant silicone is applied and tooled neatly.

Preparing for the visit

  • Tell us if there are stairs or a lift
  • Plan for the room to be out of bounds to pets and children
  • Clear the area around the damage

Advice

DIY kit or professional repair?

It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is normally cheaper.

It’s natural to want to try a repair yourself. The trouble is that kit repairs frequently look fine at first and then fail, and the old filler has to come out before a proper repair.

What bath resealing costs

We charge the same across the UK, including South Croydon. What changes the price is:

  • Previous DIY repairs that have to come out
  • The size and number of damaged areas
  • What the surface is made of
  • How many items we do on one visit

The price reflects the work involved, not where you live. You will see the full price before booking, with no extras added later.

How to get a fixed quote

Phone photos are fine. Ensure they show:

  • Details of any past repairs
  • A coin or ruler next to the damage for scale
  • Good light, ideally daylight, without flash glare
  • A close-up of the damage, in focus

Getting a price is easy: snap the damage close up and then the whole item, send them over with your postcode, and we will reply with a fixed quote. There’s no charge for the quote and you are under no obligation.

Aftercare tips

How the surface is treated afterwards matters. Here’s what we suggest:

  • Reseal when black spots won’t clean off
  • Keep the joints dry
  • Ventilate the bathroom well
  • Let steam out after showers

Avoid scraping the joints, and keep shampoo bottles off the joints.

If you notice damp, stains on the ceiling below or loose tiles, act quickly. It may be more than a reseal, so we’ll tell you if it needs a builder or plumber.

Signs you need bath resealing in South Croydon

Joints split if the bath or tray moves, often because it was sealed while the bath was empty.

Look out for these signs:

  • Gaps by the taps
  • Silicone smeared on tiles
  • Gaps in the seal
  • Discoloured, yellow sealant

Comparing quotes

  • How soon you can use it again
  • Is the price fixed, and does it include VAT?
  • How to care for the finish
  • Whether the price covers travel

Choosing a repair company

South Croydon questions

Will you leave a mess?

Dust sheets and masking go down before we start, and tidy up before we leave.

How do I stop mould in sealant?

Usually poor ventilation and moisture sitting on the joint. We use mould-resistant silicone, and ventilation helps it last.

How long does silicone take to cure?

Normally about a day later. We’ll tell you the exact time.

How quickly can you book me in?

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

Does someone need to be in?

Yes. The technician needs access to the room for the visit, at a time that suits you.

Is there a guarantee?

Yes, for a year. If there is a problem with the work in that time, we come back and put it right.

Is it OK to have pets in the house?

We ask you to keep children and pets out of the room while we work. Everywhere else in the home is fine.

Can you redo someone else’s repair?

Most of the time. Let us know what was used before and we will plan for it.
