When it isn’t the sealant

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
  • A bath, tray or worktop that moves until it’s properly fixed
  • A leaking trap, valve or supply pipe

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

What we seal

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

About our remedial sealant in Hadley Wood

Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. We’re often asked to deal with floor or wall movement joints that have failed and kitchen joints letting water behind the worktop, across expansion joints, shrunken worktop sealant and botched or over-sealed joints.

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

Whatever the size of the job, it’s backed by our one-year guarantee.

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. A few tips:

  • Keep the room well ventilated
  • Keep movement joints clear of mortar and paint
  • Always have old sealant cut out, not covered
  • Look for stains below bathrooms now and then

Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.

Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.

Do you need remedial sealant in Hadley Wood?

Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.

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

  • Leaks that keep coming back after resealing
  • Floor or wall movement joints that have failed
  • Over-sealed joints coming away
  • Wide, uneven beads that look worse than the old ones

For landlords with property near Hadley Wood station, botched sealant from a previous quick fix is easier to strip out between tenants.

What happens on the day

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on how many layers have to come out, and the area is left clean. In a London area like Hadley Wood, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  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

  • Let us know if you’ve seen damp or leaks
  • Let us know about stairs, lifts or work at height
  • Let us know about earlier repairs to the joints

Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.

Is parking an issue for remedial sealant in Hadley Wood?

Parking in Hadley Wood, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.

For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.

My shower still leaks after a reseal. Can you sort it?

Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

Should I try DIY first?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Remedial sealant in Hadley Wood: local notes

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. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
