Remedial sealant in Norbiton

How to look after the new joints

Aftercare is simple:

  • Use a soft cloth, not a scourer, on silicone
  • Never seal over old silicone
  • Find out why the sealant failed first
  • Check trays and worktops don’t move

Give the new sealant its full cure time: follow the cure time we give you.

Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.

Remedial sealant in Norbiton, done properly

Movement and expansion joints fail when the sealant cannot stretch. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. Typical jobs include smears and lumps from a botched reseal and movement joints that have split or pulled away, on shrunken worktop sealant, botched or over-sealed joints and mouldy bath & shower sealant.

Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout.

All our work comes with our 12-month guarantee.

When it isn’t the sealant

New sealant cannot fix everything, and we will tell you before work begins. Sealant won’t put right:

  • Older mastics that may need an asbestos check before removal
  • A cracked shower tray or bath (that needs repair or replacing)
  • A leaking trap, valve or supply pipe

If in doubt, phone 0345 464 0079 or email us and we will say what we think.

Surfaces we seal

  • Mouldy bath & shower sealant
  • Botched or over-sealed joints
  • Leaking tray & enclosure joints
  • Failed movement joints
  • Shrunken worktop sealant
  • Expansion joints

Bathrooms and kitchens in Norbiton

London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. London has hard water, so limescale builds up on sealant, grout and fittings.

Norbiton is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Homes close to Church of St Peter include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. For site and facilities teams at buildings such as St Paul's CofE Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What affects the quote in Norbiton

The quote reflects the job in front of us. We take into account:

  • How much there is to do
  • Whether the work is at height
  • When we can work, for business premises
  • Whether old sealant or filler has to be cut out

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

Questions from Norbiton

I live in a flat in Norbiton. Can a failed seal leak into the flat below?

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 Norbiton?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.

Can I add another job to the visit?

Yes. Tell us about everything you’d like done and you will get one quote.

Do you work for letting agents?

Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.

Does remedial work come with a guarantee?

Yes, for 12 months. If we have pointed out another problem, getting it fixed helps the new joint last.

How long does remedial resealing take?

It takes a few hours for a typical bath or shower, longer where several layers have been applied. You’ll know the timing when we quote.

Will it make a mess?

Tidy work is part of the job. Nearby surfaces are protected.

Do you work in Norbiton?

Yes. From our base in Crawley, we cover South East England, London and all of Scotland.

Surface by surface

Over-sealed & botched joints

Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and point out any existing damage.

Windows & doors

Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What we do, step by step

Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours, depending on how many layers have to come out. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  1. We start by checking the joint for movement, leaks and the reason it failed.
  2. We strip the joint completely, removing any layers below.
  3. The joint is cleaned, treated for mould and left to dry.
  4. Moving joints get backing and a flexible sealant to suit.
  5. We tool the joint and tell you about anything else that needs attention.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Keep pets and children clear of the area while we work
  • Mention any sign-in or site rules at work premises
