St Mary Cray: your questions answered
Is parking a problem for a job in St Mary Cray?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Could a tired shower seal in my St Mary Cray flat affect the neighbours below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can you regrout just the shower?
Yes. A lot of our jobs are only the shower, or the area where the grout has gone.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Could my grout be a different colour after regrouting?
Yes. Many customers do. Darker grout can hide marks and lighter grout gives a fresher look.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
How long should I wait before showering?
You will get a clear time from us before we go. Both the grout and the silicone need time to cure before they get wet.
About our regrouting in St Mary Cray
A bathroom with good tiles can still look worn if the grout has gone. Regrouting replaces the grout and keeps the tiles you have, so there’s no stripping out and no new tiles to choose. If you are dealing with stained grout that cleaning won’t shift and gaps where the shower grout has gone, 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.
You get a one-year guarantee, the same in St Mary Cray as everywhere else we work.

What happens if it’s left?
Cleaning products may brighten grout for a time, but stains and mould that have soaked in tend to return. New grout, with silicone in the corners, deals with the cause. In a flat in St Mary Cray, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

When to call us in St Mary Cray
A bathroom that stays damp keeps the grout wet, giving mould a place to grow. Black marks that come back after cleaning are often in the grout itself.
Any of these means the joints need attention:
- Discoloured grout on otherwise sound tiles
- Grout in a colour the owner wants to change
- Splashback grout that has darkened
- Stained grout that cleaning will not shift
If you look after a building such as Poverest Primary School, 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.

Regrouting around St Mary Cray
London’s water is hard, so limescale builds up on sealant, grout and fittings. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
Letting a property close to St Mary Cray station? Then a regrout while the flat is empty is quicker than working around a tenant. For an older house near a landmark such as Church of St Mary, walls and floors in older homes can move, and sealant and grout show it first.

Surface by surface
Kitchen splashbacks
Grout behind the hob and sink works hard. We renew the grout and the worktop sealant.
Bathroom floors
If floor grout keeps cracking, the floor may be moving. We check the tiles before regrouting.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Rinse the tiles after showering
- Run the extractor fan during and after a shower
- Look at the sealant in the corners now and then
- Use a squeegee on the tiles after showering
Have any tile that moves checked right away. A loose tile cracks the grout around it and open a path for water.
Tiles can come away if failed grout is left. By then, new grout alone is not enough so early action pays.
What affects the quote in St Mary Cray
We quote each job individually. These are the things that affect it:
- The type of sealant required
- Whether the work is at height
- The number of rooms or windows
- The number and length of the joints
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Any previous sealing or DIY work
- How we’d reach the joints
- The type of property
- What’s wrong with the joints now
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
