- Greasy, stained grout behind the hob
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
How we handle regrouting in New Charlton
A grout colour change can freshen a room without retiling. You might go from white to grey, or the other way round. Just mention the colour you’d like when you phone 0345 464 0079 or send us an email. We work on wet rooms, tiled floors and kitchen splashbacks, and common reasons people get in touch are cracked or crumbling grout lines and grout in corners that has cracked.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in New Charlton, getting the joints right keeps water where it belongs and the room looking clean.
There’s a 12-month guarantee on every job, whatever its size.

How to look after the new joints
To keep the joints looking good and working properly:
- Clean grout with a mild bathroom cleaner
- Skip wire brushes and scourers
- Rinse the tiles after showering
- Do not use strong acidic cleaners on grout
Clean the grout with a mild bathroom cleaner and a soft brush. Avoid neat bleach and strong acid descalers because they wear grout away.
Once grout cracks, it tends to get worse. Water gets in behind and the tiles can start to loosen, so regrouting early can save a retile.

What regrouting looks like in New Charlton
In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. There are hotels and other places to stay in and around New Charlton. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
If you live in an older home near St Catherine Labouré, older homes can move a little, which is hard on rigid grout and tired sealant. Managing a site like Royal Greenwich Trust School? Then 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.

Questions from New Charlton
Do you work for landlords with property near Charlton station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you take on hotel work around New Charlton?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you change the grout colour?
Yes, regrouting is the time to do it. Mention the colour you have in mind when you phone 0345 464 0079 or send us an email.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Do you work in New Charlton?
Yes. We’re based in Crawley and work across South East England, London and Scotland.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What happens if it’s left?
Regrouting keeps the tiles you already have. Retiling is a much bigger job: stripping, making good, new tiles and new grout, and the room is out of use for longer. If the tiles are sound, regrouting is the simpler fix. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in New Charlton.

How the job changes by surface
Kitchen splashbacks
The grout by the hob and sink takes most of the mess. We renew the grout and the worktop sealant.
Bathroom wall tiles
Whole bathroom walls can be regrouted in one visit or more, depending on the area. It’s a good time to change the grout colour.
Common problems we fix in New Charlton
A poor original job is a common cause. Grout that was too wet, not packed in or cleaned off too hard tends to wash out early.
It’s worth asking for a quote if you see:
- Floor grout that has worn and darkened
- Grout that is cracking and breaking up
- Cracked grout along the bath or tray
- Gaps where the shower grout has gone
Rented homes near Charlton station change hands often, and a regrout while the flat is empty is quicker than working around a tenant.
