Bath resealing near Croydon

About our bath resealing in Croydon

Baths, trays, basins and kitchen worktops all get resealed. Most jobs take a couple of hours, then it needs to cure. Whether it’s water getting behind the bath or tray and stained silicone, we can usually put it right, on wet rooms, shower trays & enclosures and basins & vanity units alike.

The work is covered for a year after we finish. If anything is not right, ring us and we’ll sort it.

Aftercare tips

Good habits make a big difference to how long a repair lasts:

  • Wipe the joints dry after use
  • Air the room after use
  • Run the extractor fan during and after showers
  • Clean the joints with a mild cleaner

Do not scrape the sealant with anything sharp, and do not stand bottles on the seal.

Reseal before water gets in. Split or lifting sealant is a sign it’s time.

Is resealing worth it?

Sealing over old silicone is a false economy. It soon peels, and mould stays trapped behind it. A proper reseal removes the old first. Compared with replacing, repairing normally costs far less, because there is no removal, plumbing or making good. The quote lists exactly what you’re paying for.

When a repair is not the answer

A few problems are outside what a surface repair can do:

  • Movement in the bath or tray
  • Hidden water damage
  • Loose tiles, which need refixing first

What we do, step by step

Nothing needs to be moved out of the room beforehand. We bring everything we need with us, lay protective sheets and get going once we’ve agreed what we’re doing. It normally takes around two hours, and you can get on with other things while we are there.

  1. All the old sealant is cut out and removed.
  2. We clean the joint and treat any mould.
  3. We dry the joint thoroughly.
  4. We fill a bath with water before sealing so the gap is at its widest.
  5. New mould-resistant silicone goes on and is tooled to a neat finish, taps included.

Preparing for the visit

  • Let us know about parking or access
  • Keep pets and children out of the room while we work
  • Mention any earlier repairs or resurfacing

Repairs by material

Shower trays

We put weight on a tray before sealing it, so the joint is at its widest.

Baths

Baths are resealed with water in them, to open the joint fully.

Should I try a DIY kit first?

For a hairline mark somewhere you’ll never see, a kit may be enough. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.

You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.

FAQs for Croydon

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. The rest of the house is unaffected.

Do you charge for travel?

We do not add a call-out fee. The fixed price covers the visit and the work.

How much does bath resealing cost in Croydon?

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

How do I book?

Use the quote form or ring 0345 017 0787, and we will do the rest.

When can I use the bath after resealing?

You’ll get the curing time from us.

Do you hold any accreditations?

Yes. Our accreditations include CHAS, Constructionline and SafeContractor. See our accreditations page for the full list.

Will the price change on the day?

The price is fixed for what the photos show. If there’s more, we’ll tell you before starting.

How long does a reseal take?

Most reseals take about two hours. It then needs time to cure.

For landlords and businesses

Letting agents often send us pictures straight from the inventory. You can have a price before you arrange access, and we liaise with tenants about access if you’d like us to.

Housing associations and facilities teams use us for planned and reactive repairs in Greater London and across the UK. A repair avoids taking out and refitting, which is easier on the people living there.

Prices and what affects them

There’s no charge for travel to Croydon. The price depends on:

  • Previous DIY repairs that have to come out
  • How much damage there is
  • The material and finish
  • What kind of damage it is

It helps to know what pushes a price up or down: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Send photos and you will get a fixed figure.

Getting a price from photos

It only takes a minute to photograph the damage. Try to send:

  • Your postcode, so we can check dates
  • A coin beside the damage so we can judge size
  • The material, if you know it
  • Daylight if possible, and no flash reflection

Ring 0345 017 0787, or send us photos through the quote form. With a clear picture of the damage and one of the whole bath or shower, we can give you a fixed price the same day in most cases.
