Bathrooms and kitchens in Crews Hill
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
Schools such as St John's CofE 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. If you live in an older home near Church of St John the Baptist, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Remedial sealant for homes and businesses in Crews Hill
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. If you have products that weren’t meant for the joint and dark patches showing through the sealant, we can help, on leaking tray & enclosure joints, botched or over-sealed joints and mouldy bath & shower sealant alike.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Crews Hill, remedial sealant is as much about a room looking cared for as about keeping water out.
Your job is guaranteed for a year, as with all our work.

The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied, including the tidy-up. In Crews Hill, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
How to prepare
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed

More services for Crews Hill
Signs you need remedial sealant in Crews Hill
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
If you can see any of these, it’s time to have the joints looked at:
- Mould trapped under a layer of silicone
- Thick, messy sealant smeared over tiles
- Gaps opening along the back of the worktop
- Decorators’ caulk around a bath or shower
Crews Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Your questions about remedial sealant in Crews Hill
Is parking an issue for remedial sealant in Crews Hill?
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.
Can worn sealant in a flat in Crews Hill 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.
Where are you based?
We are based in Crawley, and we work across South East England, London and Scotland.
Can you strip sealant from an acrylic tray safely?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
Can you do several jobs on one visit?
Yes. Just list everything you need and you’ll get one quote.
How long does remedial resealing take?
It takes a few hours for a typical bath or shower, longer where several layers have been applied. We will give you a timescale when we quote.
Do you work in Crews Hill?
Yes, we do. Crews Hill is part of the area we cover, and the service is the same as everywhere else.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Surface by surface
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom before resealing.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and point out any existing damage.
What happens if it’s left?
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Crews Hill, the repair is bigger than a sealant job.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.
