Bathroom resealing in Custom House

Resealing is a small job that makes a big difference. Mouldy silicone makes even a new bathroom look neglected, and a clean white or clear joint fixes it quickly. It also seals the gaps that let water behind the bath. We work on baths, sinks & splashbacks and wet rooms, and people most often call us about water escaping at the shower enclosure and black mould in the silicone that won’t clean off.

Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Custom House more than a cosmetic job.

All our work comes with a 12-month guarantee, wherever you are in Greater London.

Custom House homes and their sealant

Custom House is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Schools such as St Joachim's Catholic Primary School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Common questions in Custom House

Do you work for hotels and guest houses in Custom House?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

I let a flat near Custom House station. Can you help?

Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.

Will there be a smell?

There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

Will you leave a mess?

We keep the work tidy. Nearby surfaces are protected.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.

Do you guarantee your resealing?

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

How long will the resealing take?

One bath or shower is around two hours’ work, old sealant removal included. A whole bathroom plus the kitchen may take most of the day.

Do I need to be at home?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

The process

We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a morning or an afternoon for most single baths and showers. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Custom House. A visitor permit or a nearby bay makes the visit run more smoothly.

  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. New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
  5. We clear away and tell you when it can get wet, generally after around 24 hours.

How to prepare

  • Tell us if parking is tricky
  • Let us know about earlier repairs to the joints
  • Mention any sign-in or site rules at work premises

How to get a quote

When something else is needed

We will always be straight with you, so here’s what new sealant won’t do:

  • Movement from a bath with loose feet or no proper support
  • A leaking waste, trap or valve
  • Cracks in the tray itself rather than the joint

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

What we seal

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

Why deal with it now?

Fresh sealant smartens a bathroom or kitchen with very little disruption, which helps when a home is being let or put on the market. Lumpy sealant with smears on the tiles has the opposite effect, and it’s harder to put right later. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.

The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.

Why us?

  • Old sealant always removed completely
  • A 12-month guarantee on all work
  • White, clear, grey or coloured to suit, where the product allows
  • Trusted Arbo and Everbuild sealants

How the job changes by surface

Wet rooms

Wet room floors move slightly as they’re used, so the internal corners need silicone rather than grout. Where grout in a corner has cracked, we can replace it with sealant.

Basins & vanity units

Basins take less water than showers, but the joint behind them is splashed every day. Corners behind basins are where mould tends to start, so it’s cut out and renewed just like a bath joint.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

Signs you need bathroom resealing in Custom House

Older sealant shrinks and hardens. In kitchens it often shrinks away from the back edge, opening a hairline gap that lets water and crumbs in. Heat from the hob and strong sprays speed it along.

Most people get in touch after spotting something like this:

  • Black spots spreading through the bead
  • Leaking joints on a shower screen
  • A bead that has pulled away from the tiles
  • A messy, uneven bead from a previous reseal

For landlords with property near Custom House station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.
