Your questions about regrouting in Clapham Junction
I live in a flat in Clapham Junction. Can a failed seal leak into the flat 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. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Do you work in hotels near Clapham Junction?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you regrout part of a bathroom, like the shower?
Yes, that is common. The shower generally fails first, so many people regrout just that part.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
What does regrouting cost?

How we handle regrouting in Clapham Junction
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. Renewing both together means nothing is left half-done. If you’re dealing with stained grout that cleaning won’t shift and grout in corners that has cracked, we can put it right.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Clapham Junction are no different.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Signs you need regrouting in Clapham Junction
Harsh cleaners and scrubbing wear grout away. Bleach and acidic limescale removers can attack it with repeated use, until the joints are rough and low.
Most people get in touch after spotting one of these:
- Grout that stays dark however much it’s cleaned
- Crumbling grout between the tiles
- Grout washed out of a shower
- Splashback grout that has darkened
Homes close to Clapham Welsh Presbyterian Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Before you book anyone
- How the surfaces are prepared before sealing
- Are they insured?
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?

How to look after the new joints
Looking after new joints is easy:
- Use a soft brush rather than a wire one
- Keep an eye on the silicone along the edges
- Do not ignore a tile that feels loose
- Rinse soap off the tiles after each shower
Check the corner silicone now and then. It’s the part that moves, so it’s normally the first thing to need attention, long before the grout does.
Tiles can come away if failed grout is left. By then, new grout alone isn’t enough, so it’s worth acting early.
Regrouting in Clapham Junction: local notes
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. 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.
Clapham Junction is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Schools such as Christ Church CofE Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the visit works
On the day, we start by going over the job with you. We protect the surfaces around the joints before work begins. Most jobs take anything from a few hours to a full day, depending on the area. For a job in Clapham Junction, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First, we check for loose or hollow tiles and point out any we find.
- We rake out the old grout to an even depth, taking care of the tile edges.
- We vacuum the joints and clean out the dust.
- We fill the joints with new grout, then clean the tiles.
- The corners and edges get new silicone, because grout there would crack.
Before we arrive
- Let us know about earlier repairs to the joints
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed

What affects the quote in Clapham Junction
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- Access and height
- Working hours on commercial sites
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
When you contact us, it’s useful to know:
- If someone has resealed it before
- The type of property
- A few pictures by email, if you can
- Any access issues, like height or stairs
We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or email us with the details.
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. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
