Remedial sealant in St George in the East

The wrong product in the wrong joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. If you have beads that never stuck properly and repeat leaks from the same joint, we can put it right, on leaking tray & enclosure joints, expansion joints and botched or over-sealed joints alike.

Hard London water leaves limescale on sealant, grout and taps alike. In St George in the East, 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.

FAQs for St George in the East

Can worn sealant in a flat in St George in the East 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. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.

Can you help a landlord with a rental near Shadwell station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.

How long does remedial resealing take?

Longer than a simple reseal, because every layer has to come out. Most jobs take a few hours, and we confirm the time with your quote.

Are you an approved applicator?

Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

Do you cover St George in the East?

Yes. We work in St George in the East and the rest of Greater London, as part of our work across South East England, London and Scotland. To book, call 0345 464 0079 or email us.

Will you leave a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

Can you remove old sealant without damaging the bath?

Yes. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. We point out any damage that’s already there.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

DIY versus a professional finish

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.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What we are called out for in St George in the East

Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.

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

  • Floor or wall movement joints that have failed
  • Sealant applied over old sealant that has lifted
  • Black mould underneath the bead
  • Beads that never stuck properly

If you let a flat or house near Shadwell station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Remedial sealant in St George in the East: local notes

In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Schools such as St Paul's Whitechapel Church of England Primary School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. If you live in an older home near St Peter's, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

St George in the East is about 1 mile south-east of Whitechapel, in Greater London.

What happens on the day

When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. The work generally takes a few hours for most joints, depending on how much old sealant has to come out. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
  2. Each layer is cut out and the residue cleaned off.
  3. We treat any mould and dry the joint thoroughly.
  4. We reseal with a product suited to the joint, backed where needed.
  5. We finish neatly and point out anything that needs another trade.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Keep pets and children clear of the area while we work

What happens if it’s left?

Remedial work takes longer than a straight reseal, but not by much: it takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. In a flat in St George in the East, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.
