Remedial sealant in Maze Hill

Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. Typical jobs include gaps opening along the back of the worktop and repeat leaks from the same joint, on botched or over-sealed joints, failed movement joints and shrunken worktop sealant.

In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Aftercare tips

How long the joints last depends on use and care. Here’s what we suggest:

  • Clean sealant with mild products only
  • Keep movement joints clear of mortar and paint
  • Never seal over old silicone
  • Have loose fittings fixed before resealing

If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.

A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.

When it isn’t the sealant

Before booking, it’s worth knowing the limits:

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

Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

Surfaces we seal

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

What remedial sealant looks like in Maze Hill

Maze Hill has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.

As a London address, Maze Hill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as Christ Church, older homes can move a little, which is hard on rigid grout and tired sealant.

Maze Hill is about 1 mile north-east of Greenwich, in Greater London. Wherever you are in the SE10 postcode area, we can carry out remedial sealant at your property. Across Greater London, we cover 764 places, and Maze Hill is one of them.

All of SE10, SE3 and E14 is covered for remedial sealant. Whether your property is on Webb Road, The Avenue and Hardy Road or anywhere close by, we can help. We also cover Greenwich (1 mile south-west), Vanbrugh Park Estate (1 mile south-east), Westcombe Park (1 mile east), Blackheath (1 mile south) and Isle of Dogs (1 mile north-west). We also work in nearby towns such as London (4 miles west), City of Westminster (7 miles west), Marylebone (7 miles west), Kensington (9 miles west), St Pancras (6 miles north-west) and Shoreditch (5 miles north-west).

Around Maze Hill

FAQs for Maze Hill

Do you work in hotels near Maze Hill?

Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

I let a flat near Maze Hill station. Can you help?

Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.

Do you fix expansion and movement joints?

Yes. Backing sets the depth and stops the sealant sticking to the back.

How long will it take to strip and reseal the joint?

It takes a few hours, depending on how many layers have to come out. You will know the timing when we quote.

Will it make a mess?

No. The area is protected while we work and cleaned up afterwards.

Can you take off two layers of silicone?

Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Will there be a smell?

Possibly a little. It fades as the sealant cures, and ventilation helps.

Why deal with it now?

Adding more sealant is the usual quick fix, and it rarely works. It does not grip the old layer, leaving the leak in place and one more layer to cut out later. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Maze Hill.

The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins.

In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

How it works

We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours, depending on how many layers have to come out. For a job in Maze Hill, 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. Every layer of old sealant is cut and cleaned out.
  3. The joint is cleaned, treated for mould and left to dry.
  4. Moving joints get backing and a flexible sealant to suit.
  5. The new joint is tooled neatly and we explain anything else we found.

Before we arrive

  • Tell us about any water getting in
  • Tell us about any previous sealing or DIY attempts
  • Clear the area around the work

Advice

Common problems we fix in Maze Hill

Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.

Look out for any of the following:

  • Dark patches showing through the sealant
  • Movement joints that have split or pulled away
  • A shower that leaks however often it’s resealed
  • Thick, messy sealant smeared over tiles

Schools such as John Roan School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

What to look for in a quote

  • Whether all the old sealant comes out first
  • How the colour is chosen
  • Which sealant they’ll use, and why
  • How the surfaces are prepared before sealing
