Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
About our regrouting in Petersham
Grout fills the gaps between tiles, while sealant goes where tiles meet a bath, tray or worktop. Once grout starts to crack or wash away, water can get in behind the tiles. We rake it out and replace it, then reseal the corners and edges. We work on bathroom wall tiles, tiled floors and kitchen splashbacks, and common reasons people get in touch are cracked grout along the bath or tray and grout that stays dark however much it’s cleaned.
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. A compact bathroom that steams up every day is hard on silicone and grout.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Common problems we fix in Petersham
Movement behind the tiles cracks grout. Loose tiles, bouncy floors and timber walls can all do it, which is why we check the tiles first.
These are the problems we’re asked about most:
- Discoloured grout on otherwise sound tiles
- Dirty, worn grout on a tiled floor
- Cracked or crumbling grout lines
- A grout colour that no longer suits the room
Schools such as The Russell 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.

What regrouting looks like in Petersham
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.
As a London address, Petersham can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as St Peter's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Petersham is about 1 mile south of Richmond, in Greater London. Jobs in Petersham get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. 764 places in Greater London are on our list. London is on our list too, about 10 miles from Petersham.

Aftercare tips
To keep the joints looking good and working properly:
- Clean grout with a mild bathroom cleaner
- Do not ignore a tile that feels loose
- Clean with a soft brush, not anything metal
- Rinse the tiles after showering
Leave the area unused for as long as we advise, so it cures fully. From then on, a quick rinse after showering helps and let the room air.
Leaving failed grout can mean tiles come loose. Once that happens, regrouting won’t fix it, so it’s worth acting early.

What we cannot put right
We’ll always be straight with you, so here’s what new sealant will not do:
- Loose tiles, which need refixing first
- Leaks from pipes, valves or wastes (a plumber’s job)
- A floor or wall that keeps moving
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.

Common questions in Petersham
Is parking a problem for a job in Petersham?
Parking in Petersham, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
I let a flat near St Margarets (London) station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
What goes in the corners, grout or silicone?
Internal corners and edges are sealed with flexible silicone. Grout in those joints cracks as the building moves.
Can you regrout if a few tiles are loose?
Loose tiles need refixing before regrouting. We’ll point them out before any grout comes out.
Will the sealant be renewed as well as the grout?
Usually, yes. Corners and edges need flexible silicone, and it makes sense to renew both together.
What happens if it’s left?
Patching a few joints can look like a quick win, but patched grout rarely matches the rest, and the old grout keeps failing around them. Regrouting the whole area gives an even, lasting finish. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Petersham, the repair is bigger than a sealant job.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Petersham. It helps if you can point us to a visitor permit or a bay close to the door.
