Sanderstead Regrouting

Regrouting in Sanderstead, done properly
Across Sanderstead, we regrout tiled showers, bathrooms and kitchens. Out comes the old grout, the joints are cleaned and new grout goes in, finished with new silicone at the edges. If you are dealing with grout stained black or orange that won’t clean and grout that makes sound tiles look old, we can help, whatever the surface.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Sanderstead, that is a good reason to put tired sealant and grout right early.
All our work comes with a one-year guarantee, wherever you are in Greater London.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
When to call us in Sanderstead
Poor ventilation keeps grout damp, and damp grout is where mould grows. When black spots keep returning, the mould has usually got into the grout.
Look out for these signs:
- Grout stained black or orange that won’t clean
- Grout washed out of a shower
- Cracked grout along the bath or tray
- Floor grout that has worn and darkened
Homes close to Church of All Saints include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Questions to ask before booking
- Whether VAT is included
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
- What guarantee comes with the work
For landlords and businesses
We work for landlords and agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
We also work for property managers and facilities teams in Sanderstead and across Greater London. Several sites can go on one quote.
Leave it or put it right?
Cleaning products may brighten grout for a time, but stains and mould that have soaked in tend to return. Replacing the grout and resealing the edges is a lasting fix. 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 Sanderstead, the repair is bigger than the sealant job would have been.
Rather than a set price list, 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.

How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a shower enclosure, longer for a whole room. In Sanderstead, 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.
- We start by checking the tiles for any that are loose or hollow.
- The old grout comes out to a consistent depth, without damaging the tiles.
- Dust and debris are vacuumed out of every joint.
- We fill the joints with new grout, then clean the tiles.
- We reseal the internal corners and edges with silicone.

Advice
Bathrooms and kitchens in Sanderstead
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. London has hard water, so limescale builds up on sealant, grout and fittings.
As a London address, Sanderstead can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Rented homes near Riddlesdown station change hands often, and a regrout while the flat is empty is quicker than working around a tenant.

Aftercare tips
To keep the joints looking good and working properly:
- Check the corner silicone every few months
- Use a soft brush rather than a wire one
- Don’t use strong acidic cleaners on grout
- Use a squeegee on the tiles after showering
Use a gentle cleaner on the grout and a soft brush. Keep harsh bleach and acid limescale removers away from it, as they can break grout down.
Leaving failed grout can mean tiles come loose. By then, new grout alone is not enough so early action pays.
Common questions in Sanderstead
I let a flat near Riddlesdown station. Can you help?

Is parking a problem for a job in Sanderstead?
Parking in Sanderstead, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
How long should I wait before showering?
It varies with the products and the room. We’ll tell you exactly how long at the end of the visit.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Is regrouting a chance to pick a new grout colour?
Yes, plenty of people choose to. Darker grout can hide marks and lighter grout gives a fresher look.
Do you grout the corners?
Internal corners and edges are sealed with flexible silicone. Grout in those joints cracks as the building moves.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
