Kensal Green Regrouting
Our applicators work in Kensal Green on raking out old, cracked or stained grout and regrouting tiled walls and floors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Stained grout that cleaning won’t shift
- Floor grout that has worn and darkened
- Old grout in a dated colour
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Regrouting for homes and businesses in Kensal Green
A bathroom with good tiles can still look worn if the grout has gone. With regrouting, the tiles stay and only the grout is renewed, so nothing is ripped out. We’re often asked to deal with cracked grout along the bath or tray and stained grout that cleaning won’t shift, on shower walls, kitchen splashbacks and bathroom wall tiles.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Kensal Green, getting the joints right keeps water where it belongs and the room looking clean.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Kensal Green homes and their sealant
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. London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as St Martin, older homes can move a little, which is hard on rigid grout and tired sealant. If you look after a building such as Princess Frederica CofE Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.
Kensal Green is about 1 mile south-west of Kilburn, in Greater London.

Around Kensal Green
Around Kensal Green, our work takes us to homes and buildings near Little Wormwood Scrubs, Queens Park Community School and The Masons Arms and the streets around them.

How the visit works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. The work usually takes a few hours for a shower enclosure, longer for a whole room. For a job in Kensal Green, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We check the tiles are sound and flag any that are loose or hollow.
- Old grout is raked out to a consistent depth without chipping the tiles.
- We vacuum the joints and clean out the dust.
- Fresh grout goes into the joints and the tile faces are wiped clean.
- The corners and edges get new silicone, because grout there would crack.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Have loose tiles looked at early
- Keep an eye on the silicone along the edges
- Rinse the tiles after showering
- Use a soft brush rather than a wire one
Give the new grout the time we tell you before using the shower, so it cures fully. After that, rinse the tiles after showering and keep the room ventilated.
Leaving failed grout can mean tiles come loose. Once that happens, regrouting won’t fix it, so it’s worth acting early.
Questions from Kensal Green
Could a tired shower seal in my Kensal Green flat affect the neighbours 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. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Is parking a problem for a job in Kensal Green?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Where do you work from?
We are based in Crawley, and we work across South East England, London and Scotland.
How do I get a quote for regrouting in Kensal Green?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
How long should I wait before showering?
You will get a clear time from us before we go. The grout and sealant both need to cure before they get wet.
Do you guarantee regrouting?
Every job comes with our 12-month guarantee.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
When to call us in Kensal Green
Movement behind the tiles cracks grout. That can be a loose tile, a flexing floor or a stud wall, so we check the tiles before we start.
If you can see any of these, it’s time to have the joints looked at:
- Dirty, worn grout on a tiled floor
- Good tiles let down by tired grout
- A grout colour that no longer suits the room
- Grout that is cracking and breaking up
Rented homes near Kensal Green station change hands often, and clean grout and fresh sealant between tenancies make a bathroom look cared for again.
