How we handle remedial sealant in Bermondsey

With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re ARBOMaster approved and fully insured, and remedial work carries our 12-month guarantee. If you have a shower that leaks however often it’s resealed and mould trapped under a layer of silicone, we can help, whatever the surface.

Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest.

We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

How the job changes by surface

Leaking trays & enclosures

Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before we reseal.

Mouldy bath & shower sealant

Repeat mould usually points to a damp, poorly aired room. We’ll reseal and tell you if extraction looks to be the issue.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

If you are 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 does not work out, we can still put it right.

How it works

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. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Bermondsey. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. Surrounding tiles, trays and frames are protected first.
  2. The botched or failed sealant is cut away completely.
  3. The joint is degreased and checked for movement and leaks.
  4. New sealant goes in once the joint is dry, and is tooled smooth.
  5. We give you the cure time and explain what caused the failure.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • Mention any tricky access
  • Tell us about any water getting in

Bermondsey: your questions answered

Could a tired shower seal in my Bermondsey flat affect the neighbours below?

Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. Cutting out the old sealant and laying a new bead early stops it getting that far.

Is parking a problem for a job in Bermondsey?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

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

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

Do you cover Bermondsey?

Yes, we do. Bermondsey is part of the area we cover, and the service is the same as everywhere else.

What should I tell you?

Let us know what needs doing and where, plus photos if you have them. We will ask anything else we need to know.

Can I add another job to the visit?

Yes. More than one area can go on one quote.

Do you work for letting agents?

Yes, often. Several properties can go on one quote.

Are you fully insured?

Yes, we are fully insured for domestic and commercial work.

What sealant work can’t fix

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • A tray or bath that is cracked
  • Water damage behind tiles that needs a tiler
  • A tray or worktop that needs refixing first

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

Surfaces we seal

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

Aftercare tips

Looking after new joints is easy:

  • Check ceilings under showers for marks
  • Keep bleach and abrasives off the bead
  • Don’t wait for a small gap to become a leak
  • Have loose fittings fixed before resealing

Do not let anyone seal over it later. Over-sealing is how many remedial jobs start, so the old bead should always come out first.

Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.

How we quote for remedial sealant

The price is agreed before any work begins. It takes into account:

  • Any working-time requirements on site
  • The number of rooms or windows
  • The product the joint needs
  • Mould in or behind the old joints

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What we need to know

To help us quote quickly, please include:

  • Where the job is, and your postcode
  • A few pictures by email, if you can
  • The rough size of the job
  • Access, such as stairs, a lift or height

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or send us an email.

Do you need remedial sealant in Bermondsey?

Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.

Look out for these signs:

  • Leaks that keep coming back after resealing
  • Gaps opening along the back of the worktop
  • Products that weren’t meant for the joint
  • Sealant applied over old sealant that has lifted

For an older house near a landmark such as St Mary Magdalen Bermondsey, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Questions to ask before booking

  • How long the guarantee is
  • Who turns up on the day
  • What product goes in the joint
  • What happens if they find a problem under the old sealant
