Exeter and twenty miles round it

The black line round your bath is not going to bleach out

Mould grows inside the silicone, not on it, which is why bleach works for a fortnight and then it is back. The joint comes out and one fresh bead goes on.

The difference

The same joint, before the blade and after the bead

Drag the handle across. On the left is a bath joint where the sealant has gone black and started lifting away from the tile. On the right is the same joint with every layer taken out, the surfaces cleaned back and dried, and one fresh bead run and tooled.

Why it keeps coming back

Bleach whitens it. It does not kill what is under the surface

Mould in a sealant joint is not sitting on top of the silicone. It has grown into it, feeding on soap residue and the moisture the joint has been holding, and the black you can see is the part of a colony that reaches the surface. That is why bleach works for a fortnight and why scrubbing does nothing at all.

The second thing that keeps it coming back is what somebody did last time. Silicone does not bond to cured silicone, so a bead run over an old one is only as well attached as the layer underneath it. Half the baths we take apart have three layers on them, one of them black, and the top one is already lifting at the corner.

So the joint comes out. All of it, down to bare tile and bare acrylic, including the invisible film of residue that ruins the next bead if it is left there. Then it is cleaned, dried, and sealed once, properly. That is the whole business.

What gets resealed

Seven jobs, and a price for each of them

Most bookings are one of the first two. The rest exist because people search for them by name, and because a bathroom does not stop at the bath.

Published prices

The price card is on the site rather than behind a form, VAT included and silicone included. You can work out what your job costs before you get in touch.

The old joint comes out

Every layer, plus the residue film underneath it, before anything new goes on. That is the part that takes the time and it is the part that decides how long the new bead lasts.

What you are actually paying for

The hour is the removal. The bead is fifteen minutes

Anybody can run a line of silicone. What decides whether it is still white in five years happens before the cartridge comes out of the bag.
  • Every layer of the old joint off, including caulk and sealant strip
  • The residue film taken off with a remover rather than a scraper
  • Limescale cleared from a shower joint before anything is applied
  • Both surfaces solvent wiped and the joint dried out
  • Sanitary grade silicone with a fungicide, white or clear as the room needs
  • One pass, tooled concave so water runs off rather than sitting on it
  • Tape pulled while the bead is still wet, which is what makes the line straight
  • Anything found that is not sealant work pointed out plainly, not sealed over

The work

What the middle of the job looks like

The parts nobody photographs, which are the parts that decide how the finished line behaves.

Guides

The questions people search before they book

Answered plainly, including the ones that explain how to do the job yourself. Six articles, and not one of them is a teaser for a phone call.

Can you reseal a bath or shower without removing the old silicone?

The short answer is no. The longer answer is about what silicone bonds to, and what is living inside the joint you would be covering up.

Read it

Why does bathroom sealant go mouldy, and can it be stopped?

It grows inside the silicone, feeding on soap residue in a joint that never fully dries. What actually slows it down, and what makes no difference.

How long does silicone take to dry, and when can you use the bath?

Touch dry in under an hour, usable after twenty four. Why those are two different numbers, and what happens if you do not wait.

Why does bathroom sealant leak, and is the sealant even the problem?

Water on the floor below a bathroom has three usual causes and only one of them is the sealant. Here is how to tell which one you have before you pay for the wrong repair.

Read it

Which silicone should go in a bathroom, and does the type matter?

Sanitary grade, not general purpose. Acetoxy on tile and acrylic, neutral cure on stone and metal. White or clear is a choice, and everything else on the shelf is a distraction.

How often should bathroom sealant be replaced?

There is no fixed interval. There are four signs, and a family bathroom gets through a joint considerably faster than a spare one does.

One page for the whole coverage area rather than a page per town, because a bath in Topsham and a bath in Crediton are the same job and pretending otherwise helps nobody.

Questions

Questions we get asked

How long does a reseal take?

A single bath or shower is around an hour on site, most of which is taking the old joint out. A whole bathroom is an afternoon. What takes longer is the curing: the room needs to stay dry for the rest of the day, and a bath or shower wants a full twenty four hours before it is used.

Can you not just seal over the old sealant?

No. Silicone does not bond to cured silicone, so a new bead is only as well attached as the layer under it, and any mould in the old joint is inside the material rather than on it. Sealing over both problems hides them for a few months. It is the single most common reason a bath has been sealed three times.

Will the black mould come back?

Not from the new joint, because the old material and everything living in it is removed rather than covered. What decides the next few years is the room. A bathroom with no working extractor and a window that never opens holds humidity, and mould will return to the grout and the ceiling as well as the joint. If that is what we find, you get told.

How much is it?

A bath or a shower is £95 including VAT, both together are £150, and a whole bathroom is £185. A kitchen worktop run is £95 on its own or £35 added to a bathroom booking. The silicone is in the price and there is no call out charge.

Do I need to be there?

Somebody needs to let us in, and it helps to be there at the end so you can look at the work before it is settled. The middle of the job does not need an audience. In a rented property access is arranged with the tenant directly.

White or clear silicone?

White on most baths and showers, because it reads as part of the sanitaryware and hides a slightly uneven tile edge. Clear on dark tiles, stone and most kitchen worktops, where a white line draws attention to itself. It is your choice, and it costs the same.

Do you cover my area?

Exeter and roughly twenty miles round it, which takes in the city districts, the estuary towns, the East and Mid Devon market towns and the Teign valley. The areas page lists everywhere covered. Just outside it, ask, and you will get a straight answer rather than a maybe.
