Bath resealing in Harlington

Looking after it afterwards

Once the work has cured, treat it gently:

  • Reseal at the first sign of lifting
  • Wipe the joints dry after use
  • Store bottles on a shelf
  • Run the extractor fan during and after showers

Good ventilation is the best protection, and wipe the joints after use to keep mould away.

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

Materials and what they mean for the repair

Baths

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

Shower trays

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

Honest limits

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

  • Tiles that move, until they’re refixed
  • Movement in the bath or tray
  • Hidden water damage

How we price bath resealing

We give every job a fixed quote from pictures. This is what makes a difference:

  • Whether old repairs or coatings need taking off
  • Unusual colours or finishes
  • Whether we combine several jobs
  • The material and finish

Instead of hourly rates, we fix the price before we start. Damage, material and access decide it, and combining items on one visit brings it down.

Send photos for a quote

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

  • Your postcode, so we can check dates
  • A wider photo showing the whole bath or shower
  • One sharp close-up of the damage
  • Daylight if possible, and no flash reflection

There is no need for us to visit first. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll come back to you with a fixed figure.

When to call us in Harlington

In time, even good sealant discolours. Steam, soap and movement all wear it down.

You may need us if you’ve spotted any of these:

  • Damp near the bath
  • Missing sealant behind the taps
  • Discoloured, yellow sealant
  • A messy previous reseal

What to look for in a quote

  • How to care for the finish
  • What protection goes down before work starts
  • How long it needs to cure
  • Whether the price covers travel

DIY repairs versus a professional job

It’s tempting to reach for a kit, but the repairs we redo most often are DIY ones that have discoloured or lifted. Getting it right first time is usually cheaper.

A DIY attempt is not a disaster. We remove the old filler and start again, so it doesn’t stop a professional repair. It does add a little time, so tell us about it when you send photos.

How it works

Your technician turns up at the time we agreed with you and checks the damage against your photos first. Dust sheets and masking tape go down before any work starts. Most visits take around two hours, and the room is left clean and tidy.

  1. All the old sealant is cut out and removed.
  2. We clean the joint and treat any mould.
  3. The joint is dried thoroughly.
  4. Baths are filled with water first, so the joint is at its widest.
  5. We apply new mould-resistant silicone and tool it to a neat finish, taps included.

Before we arrive

  • Move bottles, mats and clutter away from the area
  • Let us know about parking or access
  • Let us know if it has been repaired before

Questions from Harlington

Do I need to be at home?

Yes. We need access to the room while we work, at a time that suits you.

Do you hold any accreditations?

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

I rent my home. Can I book you?

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

Do you charge for travel?

No. Our quotes include travel, with the same prices everywhere we work.

When can I use the bath after resealing?

You’ll get the curing time from us, typically around a day.

Can I add another job to the visit?

Of course, and it typically saves money. Send pictures of everything together and we will quote them together.

How do I stop mould in sealant?

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

Is it worth repairing rather than replacing?

Generally, if the item is otherwise sound. A repair avoids removal and making good. We will tell you honestly if replacement makes more sense.

Why it’s worth resealing in Harlington

Putting new silicone over old doesn’t last. It soon peels, and traps mould underneath. We remove the old sealant completely. Most people are surprised how affordable a repair is, especially compared with replacing and refitting. Send photos and we’ll give you the exact figure.
