Bathroom resealing in Sidcup

Aftercare tips

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

  • Never pick at the silicone with a blade
  • Run the extractor fan during and after every shower
  • Wait for the cure time we give you
  • Move toiletries away from the joint

Clean the silicone with care: warm soapy water and a soft cloth do the job. Avoid scouring pads and anything sharp, because a damaged bead gives mould a foothold.

There’s no need to wait for a full refurbishment. Sealant is a maintenance item, like the paint on a window frame, and renewing it as soon as it fails protects everything around it.

How we handle bathroom resealing in Sidcup

The secret of a lasting bead is the preparation. The old sealant is removed to the last smear, after which the joint is degreased and any mould treated. New silicone goes on only when the joint is fully dry. We’re often asked to deal with mouldy sealant that has gone black and shrunken sealant along the back of a worktop, on shower trays & enclosures, basins & vanity units and wet rooms.

In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout.

Each job carries a 12-month guarantee, large or small.

What happens if it’s left?

Fresh sealant smartens a bathroom or kitchen with very little disruption, which matters if you are letting a property or selling it. A smeared, uneven DIY bead does the opposite. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Sidcup, the repair is bigger than the sealant job would have been.

The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.

What you get with us

  • Quality sealants from Arbo and Everbuild
  • Fully insured
  • Colour agreed with you before any work starts
  • ARBOMaster approved applicator

Take a look at what affects the cost and what customers say.

What happens on the day

You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen in most cases. In Sidcup, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. We look at every joint first and check for movement or leaks.
  2. The old silicone is cut out completely, along with the film it leaves on the tiles.
  3. Joints are degreased and any mould is treated.
  4. When the joint is dry, and a bath has been filled with water, the new silicone goes on.
  5. We tool the bead to a neat finish and give you the cure time, generally around 24 hours.

Getting ready for the visit

  • Tell us if parking is tricky
  • Mention any sign-in or site rules at work premises
  • Where the joints are inside, avoid wetting them before we arrive

Sidcup homes and their sealant

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.

Rented homes near Sidcup station change hands often, and fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. As a London address, Sidcup can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. In the older streets around Holy Trinity Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Questions from Sidcup

Is parking an issue for bathroom resealing in Sidcup?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.

Could a tired shower seal in my Sidcup flat affect the neighbours 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. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.

Where are you based?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

Do you do kitchens as well as bathrooms?

Yes. Kitchen joints get extra degreasing before the new bead goes on, then we reseal in a colour to suit.

What colours of sealant can you use?

White and clear are the most common choices, but other colours can be used to suit tiles and worktops. Let us know your preference when you ask for a quote.

Is the work guaranteed?

Yes. We give a 12-month guarantee on every job, and we are ARBOMaster approved applicators.

Is it worth trying it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Surface by surface

Kitchen worktops & upstands

Worktop joints get wet and wiped every day. We seal them in a colour that suits the worktop, so the line doesn’t stand out.

Shower trays & enclosures

Water often gets past the wall profile of a shower enclosure. It’s resealed along with the tray joints, following the enclosure maker’s guidance on which side to seal.

What affects the cost of bathroom resealing

Jobs vary more than people expect. What affects the quote:

  • The old material and how stubborn it is
  • The product the joint needs
  • When we can work, for business premises
  • How many areas need sealing

Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Asking for a quote

When you call or email, it’s useful to know:

  • The address or postcode of the job
  • If someone has resealed it before
  • Pictures of the joints, sent by email
  • If it’s domestic, commercial or a hotel

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

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.
