Remedial sealant in Bayswater

About our remedial sealant in Bayswater

Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out before the joint can be done properly. Typical jobs include dark patches showing through the sealant and gaps opening along the back of the worktop, on leaking tray & enclosure joints, botched or over-sealed joints and failed movement joints.

Hard London water leaves limescale on sealant, grout and taps alike. In Bayswater, remedial sealant is as much about a room looking cared for as about keeping water out.

All our work is covered by our one-year guarantee.

Why act early in Bayswater

It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Why book with us

  • Anti-fungal sanitary silicone in wet areas
  • More than 20 years in sealant work
  • You choose the colour before work begins
  • We are fully insured

Common problems we fix in Bayswater

Movement tears sealant that is not designed for it. Flexing baths, rocking trays and building movement joints split any bead that is too stiff or too thin.

If you can see any of these, it’s time to have the joints looked at:

  • Repeat leaks from the same joint
  • Mould trapped under a layer of silicone
  • Wide, uneven beads that look worse than the old ones
  • Sealant that came away because the surface wasn’t prepared

For landlords with property near London Paddington station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What your quote should include

  • What happens if the job turns out different
  • Is the old sealant removed completely?
  • Whether they’re fully insured
  • What guarantee comes with the work

Our hiring checklist

Can I do it myself?

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Keeping the joints in good condition

Aftercare is simple:

  • Check trays and worktops don’t move
  • Run the fan after every shower
  • Keep an eye on the ceiling below the bathroom
  • Find out why the sealant failed first

If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.

Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.

How the visit works

There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Bayswater, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  1. We start by checking the joint for movement, leaks and the reason it failed.
  2. All the old sealant comes out, including any layers underneath.
  3. We clean the joint, treat any mould and let it dry.
  4. We use the right backing and sealant for any joint that moves.
  5. We tool the joint and tell you about anything else that needs attention.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Tell us about any previous sealing or DIY attempts
  • On commercial sites, let us know about site rules

Bayswater questions

Can worn sealant in a flat in Bayswater cause a leak downstairs?

Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.

Is parking an issue for remedial sealant in Bayswater?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.

Do the sealants smell?

Sometimes, a little. It fades as the sealant cures.

What should I tell you?

The location, the problem and the rough size of the job. If you can, email a few pictures.

Yes. We cover Bayswater. To book, ring 0345 464 0079 or email us.

Can I do it myself?

Can you quote for more than one area?

Yes. Tell us about everything you’d like done and we will quote it together.
