About our bathroom resealing in Derry Downs
Showers work their sealant harder than baths. Tray edges, screen profiles and wet room joints all rely on silicone to stay watertight. Each gets a bead of anti-fungal sanitary silicone, finished smooth so water drains away rather than collecting. Typical jobs include lumpy, uneven sealant from a DIY attempt and a reseal done over the top of the old bead, on basins & vanity units, wet rooms and shower trays & enclosures.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Derry Downs, getting the joints right keeps water where it belongs and the room looking clean.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Avoid abrasive pads on the sealant
- Dry the bead with a towel now and then
- Move toiletries away from the joint
- Keep an eye on the corners, where splits start
Have a look at the joints every few months. A small split or a corner lifting is easy to spot, and if anything looks wrong, just phone 0345 464 0079 or drop us an email.
A few black dots in the silicone soon become a black line. When it has grown right through, it rarely cleans out. Catching it early keeps it a simple reseal.
What happens if it’s left?
Mould removers can fade the surface of a stained bead, but where mould is inside the silicone it generally comes back. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. 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 Derry Downs, the repair is bigger than the sealant job would have been.

Bathroom resealing around Derry Downs
London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. 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.
Schools such as St Philomena's 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. For landlords with property near St Mary Cray station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

Surface by surface
Wet rooms
In a wet room, the joints between floor and walls take standing water. They get anti-fungal sanitary silicone, working on the surface joints, not the tanking or drainage.
Basins & vanity units
On a basin, neatness shows: the bead is right in front of you, so it’s tooled cleanly and evenly, finished in a colour that suits the basin.

Common questions in Derry Downs
Do you take on hotel work around Derry Downs?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you work for landlords with property near St Mary Cray station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Are you insured?
Yes. We’re fully insured for every job we do.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you guarantee your resealing?
Yes, a one-year guarantee. Looking after the joint as we suggest helps it last.
When to call us in Derry Downs
The wrong product fails fast. Decorators’ caulk and all-purpose sealants aren’t made for constant wetting, so they stain, crack or go mouldy before long. Wet areas call for a sanitary silicone with an anti-fungal additive.
Look out for these signs:
- Black mould in the silicone that will not clean off
- Damp behind the bath or under the tray
- Two layers of silicone, both failing
- Lumpy, uneven sealant from a DIY attempt
As a London address, Derry Downs can be tricky for parking: let us know about parking bays, permits or a driveway.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen and we leave things clean and tidy. In Derry Downs, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First, each joint is checked for movement and signs of water.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- The joint is cleaned, degreased and treated for mould.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- The bead is tooled smooth and you are told the cure time, usually around 24 hours.
How to prepare
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
