Bathroom resealing in New Cross

Surface by surface

Shower trays & enclosures

Water often gets past the wall profile of a shower enclosure. We reseal it along with the base of the enclosure, following the enclosure maker’s guidance on which side to seal.

Sinks & splashbacks

Water getting under the rim of an inset sink can soak the worktop. We reseal the visible edge of the sink where it has failed.

How we handle bathroom resealing in New Cross

Homes in New Cross have the same weak spots as anywhere else: the long edge of the bath, the base of the shower tray, the back of the basin and the line along the worktop. Every joint is cut out, cleaned and left dry before it’s resealed. We work on kitchen worktops & upstands, wet rooms and shower trays & enclosures, and common reasons people get in touch are two layers of silicone, both failing and leaks into the floor or ceiling below.

Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in New Cross, getting the joints right keeps water where it belongs and the room looking clean.

There’s a 12-month guarantee on every job, whatever its size.

The process

All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a couple of hours for a single bath or shower. In New Cross, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We start by protecting the area and stripping out the old bead.
  2. Next, the joint is cleaned and any mould is treated.
  3. The joint is left to dry, and baths are filled with water first.
  4. A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
  5. Finally we tidy up and explain the cure time before we leave.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • Let us know if you’ve seen damp or leaks
  • For indoor joints, keep the area dry beforehand if you can

FAQs for New Cross

Do you work in hotels near New Cross?

Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

Can worn sealant in a flat in New Cross cause a leak downstairs?

It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Are you fully insured?

Yes, we are fully insured for every job we do.

Do you work in New Cross?

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

How do I get a quote for bathroom resealing in New Cross?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.

Do you take out the old sealant first?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Can you get rid of the black mould in my sealant?

Yes, we replace the mouldy bead. Sprays can fade the marks, but cutting it out and resealing is what lasts. Good ventilation helps keep it away.

Bathroom resealing around New Cross

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’s water is hard, so limescale builds up on sealant, grout and fittings.

For an older house near a landmark such as St James's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Letting a property close to New Cross station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

Do you need bathroom resealing in New Cross?

Sealant laid on a damp, dusty or greasy joint never bonds properly. Traces of soap, bath oil and old sealant stop it gripping, so a rushed job can start to lift early.

It’s worth asking for a quote if you see:

  • Leaks into the floor or ceiling below
  • Shrunken sealant along the back of a worktop
  • Two layers of silicone, both failing
  • Smears of silicone across the tiles

New Cross is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What to look for in a quote

  • When the joint can take water or movement
  • Who does the work, and how experienced they are
  • What guarantee comes with the work
  • Whether they’re fully insured

Our hiring checklist

What we can’t put right

It helps to know what we cannot do:

  • Movement from a bath with loose feet or no proper support
  • A cracked shower tray or bath (that needs repair or replacement)
  • Water getting in through the grout rather than the sealant

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

Where we work in New Cross

  • Wet rooms
  • Sinks & splashbacks
  • Basins & vanity units
  • Kitchen worktops & upstands
  • Shower trays & enclosures
  • Baths

How to look after the new joints

Looking after new joints is easy, and it makes a real difference:

  • Move toiletries away from the joint
  • Keep the fan on for a while after bathing
  • Dry the bead with a towel now and then
  • Use gentle cleaners on the silicone

In a kitchen, don’t let water sit along the back of the worktop. A dry joint lasts longer.

Each shower pushes a little more water through a failed joint. Left alone, it soaks into the floor, the wall behind the tiles or the ceiling below. Resealing early stops it.

Work for landlords, hotels and businesses

Letting agents and landlords in New Cross can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.

In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

Should I try it myself first?

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
