Bath resealing for South Darenth homes

Do you need bath resealing in South Darenth?

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

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

  • An untidy old seal
  • Discoloured, yellow sealant
  • Gaps by the taps
  • Damp near the bath

Our hiring checklist

Bath resealing in South Darenth, done in place

The key to a good reseal is getting all of the old silicone out. Fresh sealant does not stick to old, which is why so many DIY reseals peel. Common call-outs are for missing sealant behind the taps and sealant that’s split or lifting, on baths, kitchen worktops & sinks and shower trays & enclosures.

Peace of mind is built in: our one-year guarantee applies to every job, and we explain what it covers before booking.

How we price bath resealing

There are no hourly rates or hidden extras. The price is based on:

  • How many items we do on one visit
  • Access to the area
  • The material and finish
  • How much damage there is

Our prices are the same across the UK, with no extra for South Darenth. The job itself decides the price: the material, the amount of damage and how many items.

Send photos for a quote

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

  • What it’s made of, if you know
  • A coin beside the damage so we can judge size
  • A clear, close picture of the problem area
  • A picture taken from further back

Call 0345 017 0787 or use the quote form. With a clear picture of the damage and one of the whole bath or shower, we can price the job without visiting.

Looking after it afterwards

Once the work has cured, treat it gently:

  • Clean the joints with a mild cleaner
  • Reseal when black spots will not clean off
  • Let steam out after showers
  • Run the extractor fan during and after showers

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

Do not wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.

DIY kit or professional repair?

A DIY attempt isn’t a disaster. We remove the old filler and start again, so it will not stop us repairing it. Just mention it when you send photos, as it can add time.

You can buy a DIY kit for most repairs, and they can make a small mark look better. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.

Your questions about bath resealing in South Darenth

Can I get a quote without a visit?

Usually, yes. A close-up and a wider photo are enough to give a fixed price.

How long does a reseal take?

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

What areas do you cover?

Across the UK, so South Darenth is covered. Our prices are the same everywhere.

Do you work for landlords and businesses?

Yes. We carry out repairs for householders, landlords, letting agents, builders and businesses.

What if the damage is worse than the pictures show?

We will show you and explain before doing anything extra. You won’t be charged for anything you haven’t agreed.

Can tenants book a repair?

We’re happy to deal with the tenant, landlord or agent. Just ensure the landlord agrees.

Can new silicone go over old?

All the old sealant comes out. Fresh silicone does not stick to old.

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

Most of the time. Tell us what was done before.

When a repair is not the answer

We’d rather lose a job than do one that will not last, so here’s what a repair cannot put right:

  • A flexing bath
  • Gaps too big for silicone alone
  • Water damage behind the bath that needs a builder

Not sure? Send pictures and we’ll give you a straight answer.

Materials we repair

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

How the visit works

Your technician turns up when we said we would and looks over the damage before anything else. The floor and nearby surfaces are covered before we open a single tin. Most visits take a couple of hours, and we leave the room as we found it.

  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. We fill the bath, or weight the tray, to open the joint.
  5. New mould-resistant silicone is applied and tooled neatly.

Getting ready for the visit

  • Keep children and pets away from the room on the day
  • Have a window or extractor fan available
  • Clear toiletries, mats and anything else from around the area

Getting a price

Pricing is simple: take a close-up of the damage and a photo from further back, send them over with your postcode, and you’ll get a fixed quote back. There is no charge for the quote and you are under no obligation.

Hotels, guest houses and holiday lets cannot afford rooms out of action for long, so we keep visits short and tidy. We’ll fit around changeovers where we can.

Why it’s worth resealing in South Darenth

Resealing is routine maintenance. Leaving split or mouldy sealant lets water get behind the bath or tray, and that damage costs much more to fix. The price reflects the work involved, not your postcode. You’ll see the full price before you book.
