Bathrooms and kitchens in North Harrow
London’s water is hard, so limescale builds up on sealant, grout and fittings. 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.
Managing a site like Longfield Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Harrow-on-the-Hill station change hands often, and a regrout while the flat is empty is quicker than working around a tenant.

Regrouting in North Harrow, done properly
Across North Harrow, we regrout tiled showers, bathrooms and kitchens. Out comes the old grout, the joints are cleaned and new grout goes in, finished with new silicone at the edges. We work on bathroom floors, tiled floors and wet rooms, and the jobs we see most are a grout colour that no longer suits the room and discoloured grout on otherwise sound tiles.
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.
Big or small, you get the same one-year guarantee in North Harrow and across Greater London.

What the job involves on each surface
Kitchen splashbacks
We can regroute a splashback with the kitchen left in place. The joint along the worktop is resealed with silicone.
Bathroom floors
New floor grout makes a big difference to how a bathroom looks. The edges where floor meets wall or bath get silicone.
What we are called out for in North Harrow
Strong cleaning products and hard scrubbing slowly erode grout. Some bleaches and acid descalers break grout down over time, until the joints are rough and low.
Common reasons people contact us include:
- Grout washed out of a shower
- Grout that’s cracking and breaking up
- Grout stained black or orange that won’t clean
- Floor grout that will not come clean
North Harrow is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What your quote should include
- The length of the guarantee
- Whether the sealant suits the joint
- Whether they’re fully insured
- Whether all the old sealant comes out first
What happens if it’s left?
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. 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. Dealing with it early is far simpler for homes in North Harrow.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why us?
- An ARBOMaster approved applicator
- Neat joints and a tidy finish
- Every job guaranteed for a year
- Homes, businesses and hotels

What affects the cost of regrouting
The quote reflects the job in front of us. We take into account:
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
- The type of sealant required
- How easy the joints are to reach
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- A few photos by email, if you can
- Where the property is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
North Harrow questions
Could a tired shower seal in my North Harrow 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. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Can parking be tricky for a visit in North Harrow?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels.
What if some of my tiles are loose?
Tiles that have come away need sorting first. We will show you which ones before any grout comes out.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Where is Mr Mastic based?
We work from Crawley. We cover North Harrow and the rest of Greater London.
How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to a full day, depending on the area. In North Harrow, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we agree what’s being done and flag any loose tiles.
- We remove the old grout carefully.
- 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
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules

Advice
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 just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
