Regrouting for homes and businesses in Charlton
Regrouting is generally paired with resealing. Grout is for the joints between tiles, but internal corners and edges flex, so they’re sealed with silicone rather than grout. Doing both at once leaves the whole area sound. We work on kitchen splashbacks, wet rooms and bathroom wall tiles, and people most often call us about old grout in a dated colour and discoloured grout on otherwise sound tiles.
Somewhere as small as Charlton, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
You get a 12-month guarantee, the same in Charlton as everywhere else we work.

What we’re called out for in Charlton
Poor ventilation keeps grout damp, giving mould a place to grow. Black marks that come back after cleaning are often in the grout itself.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where the shower grout has gone
- Grout stained black or orange that will not clean
- Old grout in a dated colour
- Floor grout that will not come clean
Managing a site like Highbury Infant School and Nursery? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Charlton: your questions answered
Do you take on hotel work around Charlton?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Do you cover smaller places like Charlton?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
When can I use the shower again?
We give you a time before we leave. The wait depends on the products and conditions so please stick to it.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Is it possible to regrout only the shower area?
Yes. Many jobs are just the shower walls, or just the joints that have failed.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
Why deal with it now?
Colouring the surface of old grout is a quick cosmetic fix. They don’t fill cracks or stop water, and stains can show through again. A proper regrout puts new grout in the joint. Around Charlton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

Bathrooms and kitchens in Charlton
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. Charlton has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Letting a property close to Hitchin station? Then stained grout drags a rental down, and regrouting between lets puts that right. Homes close to St Mary's Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.
Charlton is about 1 mile south-west of Hitchin, in Hertfordshire. Homes, rented property, offices and hotels in Charlton can book us for regrouting, old or new, large or small. The work is guaranteed for a year. 381 places in Hertfordshire are on our list, large and small. For nearby work, see our London page (31 miles or so).

If you are just outside Charlton, we cover Gosmore (1 mile south-east), Hitchin (1 mile north-east), Benslow (1 mile north-east), Bearton (1 mile north) and Westmill (1 mile north).

Local landmarks in Charlton
We work in homes and buildings around Hitchin Boys' School, The Three Moorhens Public House and Kingshott School and the streets around them.

Not far away are Markham's Hill and Oughtonhead Nature Reserve.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Use a squeegee on the tiles after showering
- Rinse the tiles after showering
- Have loose tiles looked at early
- Run the extractor fan during and after a shower
Give the new grout the time we tell you before using the shower, so it can harden properly. After that, rinse the tiles after showering and keep the room ventilated.
Fixing grout early is a small job. Left, the same problem can let water through, so get it looked at when you notice it.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The work normally takes anything from a few hours to a full day, depending on the area, depending on how much there is to do.

How the job changes by surface
Corners and edges
Internal corners move, so they get silicone, not grout.
Bathroom floors
New floor grout makes a big difference to how a bathroom looks. The edges where floor meets wall or bath get silicone.
