How the job changes by surface
Wet rooms
New grout in a wet room keeps the surface sound. It can’t fix waterproofing below the tiles.
Bathroom floors
Regrouting a floor brightens the whole room. Floor-to-wall and bath joints are sealed, not grouted.
Regrouting for homes and businesses in Isleworth
We work across Isleworth, regrouting bathrooms, showers and kitchens. The old grout is raked out, the joints cleaned and new grout laid, and we finish by resealing the edges. Typical jobs include crumbling grout between the tiles and gaps where the shower grout has gone, across tiled floors, bathroom floors and kitchen splashbacks.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Isleworth are no different.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

What regrouting looks like in Isleworth
There are hotels and other places to stay in and around Isleworth. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
For landlords with property near Isleworth station, stained grout drags a rental down, and regrouting between lets puts that right. Schools such as St Mary's Catholic 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.
Isleworth is about 2 miles north of Twickenham, in Greater London. Whether you’re in the middle of Isleworth or further out, regrouting is available for homes and businesses alike.

Local landmarks in Isleworth
In Isleworth, that means homes and buildings near The George Inn, Kneller Hall Junior School and Gumley House RC Convent School and the streets around them. There’s a railway station in Isleworth itself: Isleworth station.

Green spaces nearby include Richmond Hill and Kew Gardens Lake.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Isleworth questions
Do you work for landlords with property near Isleworth station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
I live in a flat in Isleworth. Can a failed seal leak into the flat below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. Cutting out the old sealant and laying a new bead early stops it getting that far.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is resealing included with regrouting?
Yes, in most cases. Fresh grout next to old, mouldy silicone would look odd and could still leak.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Do you cover Isleworth?
Yes. We cover Isleworth and the rest of Greater London, as part of our work across South East England, London and Scotland. To book, phone 0345 464 0079 or drop us an email.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Do you grout the corners?
We use silicone in corners and along edges. Grout in those joints cracks as the building moves.
Why act early in Isleworth
It’s tempting to fill a few cracks yourself, but patched grout rarely matches the rest and the old grout carries on failing. Doing the full area gives you one colour and sound joints throughout. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How it works
At the end, we look at the finished work together. The work normally takes a few hours for a shower enclosure, longer for a whole room, depending on how much there is to do. In Isleworth, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We agree the area to be regrouted and point out any loose tiles.
- Grout is raked out without chipping the tiles.
- The joints are cleaned out and vacuumed.
- The new grout goes in, then the tile faces are cleaned.
- Internal corners and edges are resealed.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Mention any parking rules near the property

Advice

What else we do in Isleworth
Signs you need regrouting in Isleworth
Grout is porous, so water, soap and grime soak into it. Given time, it discolours and begins to break down and showers that get daily use suffer most.
Any of these means the joints need attention:
- Floor grout that has worn and darkened
- Grout in corners that has cracked
- Grout that makes sound tiles look old
- Grout that’s cracking and breaking up
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.
What your quote should include
- Is the old sealant removed completely?
- What product goes in the joint
- How long the guarantee is
- Which colour the sealant will be
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Wipe or squeegee the shower walls
- Check the corner silicone every few months
- Run the extractor fan during and after a shower
- Give the walls a quick rinse after use
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 let the room air.
Once grout cracks, it tends to get worse. Water gets behind the tiles, and they can begin to come away, so regrouting early can save a retile.
