How we price bath resealing

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

  • Where the damage is and how we get to it
  • Any earlier repairs that need removing first
  • How many items we do on one visit
  • How much damage there is

A few things move the price: access, material, the extent of the damage and whether we can do several items together. Send photos and you’ll get a fixed figure.

How to get a fixed price

It only takes a minute to photograph the damage, and it saves a visit. Please include:

  • Details of any past repairs
  • A coin beside the damage so we can judge size
  • One sharp close-up of the damage
  • Where you are, by postcode

A quote takes minutes to ask for: take one close-up and one wider shot of the bath or shower, add your postcode and send them over. You will get a fixed quote, not an estimate.

Bath resealing in Radwell without replacing anything

We reseal baths with them filled with water, so the joint opens fully, so the seal does not tear when the bath is first used. Whether it’s discoloured, yellow sealant and an untidy old seal, we can help.

Whatever the size of the job, you get the same one-year guarantee.

What happens on the day

Your technician turns up at the time we agreed with you and checks the damage against your pictures first. 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. The old silicone is cut out completely.
  2. Residue is removed and the joint cleaned.
  3. We treat mould and dry the joint thoroughly.
  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

  • Open a window if you can
  • Have somewhere for us to park nearby if possible
  • Keep children and pets away from the room on the day

Advice

FAQs for Radwell

Are there extra charges for Radwell?

Travel is included in the price, and we charge the same wherever you are.

Will you leave a mess?

We protect the room with dust sheets and masking first, and we clean up when we have finished.

I rent my home. Can I book you?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Can you repair something that’s been repaired before?

Typically, yes. We remove the old repair before doing a new one.

Can you price it without visiting?

Nearly always. If photos do not show enough, we’ll ask for another angle.

What happens once I’ve sent photos?

You will get a fixed quote back, plus dates. You are under no obligation.

Do you work for landlords and businesses?

Yes, frequently. We can quote for several properties together and work between tenancies.

Can you reseal over the old silicone?

All the old sealant comes out. Fresh silicone doesn’t stick to old.

Is resealing worth it?

A reseal is one of the cheapest bathroom jobs there is. Leaving failed sealant can let water cause damage that costs far more to fix. There are no surprise extras on the day. The price we quote from your pictures is the price you pay, unless the damage turns out to be different, in which case we talk to you first.

Should I try a DIY kit first?

For a hairline mark somewhere you will never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, a professional repair is worth it.

What a professional repair adds is preparation, colour matching and finishing. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.

Do you need bath resealing in Radwell?

Even good sealant eventually discolours, especially in a busy family bathroom. Steam, soap and movement all take their toll.

If you can see any of these, send us a photo:

  • Sealant that is split or lifting
  • Silicone smeared on tiles
  • Leaks at the edges
  • Missing sealant behind the taps

10 questions to ask before you book

What your bath or shower is made of matters

Baths

Baths are resealed with water in them, so the joint is at its widest.

Shower trays

Trays are sealed with weight on them, for the same reason.

Keeping it looking good

Once the work has cured, treat it gently:

  • Do not stand toiletries on the seal
  • Give the seal a regular clean
  • Ventilate the bathroom well
  • Reseal when black spots won’t clean off

Run the extractor fan, wipe the joints dry after use, and clean them regularly with a mild cleaner to slow mould growth.

Mouldy sealant is more than a cosmetic problem. Resealing early keeps water out of the walls and floor.

What we can’t put right

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

  • Tiles that move, until they’re refixed
  • Gaps too big for silicone alone
  • A flexing bath

Send us pictures and we will tell you honestly.
