About our bathroom resealing in Cumnor

It is not only bathrooms. The joint between worktop and wall, the edge of the sink and the bottom of the splashback all take splashes every day, and water that gets into the back edge of a worktop can swell the board. We reseal them with a kitchen-suitable silicone, matched to the worktop where it’s on show. We’re often asked to deal with new sealant laid over old sealant that is now lifting and damp behind the bath or under the tray, on baths, shower trays & enclosures and sinks & splashbacks.

Being in a small place like Cumnor makes no difference to the job itself: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.

Big or small, you get the same 12-month guarantee.

Surface by surface

Baths

The long joint down the side of a bath is where most leaks start, particularly where there’s a shower over the bath. It gets one smooth bead of anti-fungal silicone, tooled so water cannot sit on it.

Basins & vanity units

On a basin, neatness shows: the bead is right in front of you, so it’s tooled cleanly and evenly, finished in a colour that suits the basin.

How to look after the new joints

Good habits help new joints last longer. A few tips:

  • Never pick at the silicone with a blade
  • Keep an eye on the corners, where splits start
  • Keep bottles off the sealant line
  • Use gentle cleaners on the silicone

Give the silicone time to cure before it gets wet, which is generally around 24 hours. After that, a quick wipe after showering helps keep it clean.

Each shower pushes a little more water through a failed joint. Left alone, it soaks into the floor, the wall behind the tiles or the ceiling below. Resealing early stops it.

Signs you need bathroom resealing in Cumnor

Sealing over old silicone is one of the commonest mistakes we find. Fresh silicone can’t grip the old bead underneath, so it peels, leaks and hides mould behind it.

These are the problems we’re asked about most:

  • New sealant laid over old sealant that is now lifting
  • Sealant that has split, shrunk or peeled away
  • Gaps where the bath or tray has moved
  • Black mould in the silicone that won’t clean off

Homes close to Church of St Michael include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Our hiring checklist

Can I do it myself?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What we cannot put right

We won’t take on work that will not last, so here’s what sealant can’t put right:

  • Loose or hollow tiles, or failed tanking behind them
  • A tray that rocks until it’s re-bedded
  • Leaks from a shower valve, waste or pipework (a plumber’s job)

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

Common questions in Cumnor

Is Cumnor in your area for bathroom resealing?

Do you cover smaller places like Cumnor?

Yes, Cumnor is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Can you do several jobs on one visit?

Yes, and it often makes sense. Doing several areas at once is normally more efficient.

Do you work for landlords and businesses?

Yes, regularly. Several properties can go on one quote, and between tenancies is a good time for the work.

How much does bathroom resealing cost in Cumnor?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.

Will you leave a mess?

What do you need from me for a quote?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.

Leave it or put it right?

Bleach and mould sprays may lighten black marks for a while, but where mould is inside the silicone it usually comes back. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. Around Cumnor, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

How the visit works

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes a morning or an afternoon for most single baths and showers. For a village or hamlet like Cumnor, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. First the area is protected and every bit of old sealant removed.
  2. We clean and degrease the joint and treat any mould.
  3. We let it dry fully and fill the bath with water before sealing.
  4. We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
  5. We tidy up and give you the cure time, usually around 24 hours.

Preparing for the visit

  • Mention any tricky access
  • Clear the area around the work
  • Mention any leaks or damp you’ve noticed
