Bathrooms and kitchens in Mill Hill
London has hard water, which leaves limescale on sealant, grout and taps. 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.
For an older house near a landmark such as St Paul's Church, walls and floors in older homes can move, and sealant and grout show it first. Managing a site like St Paul's CofE Primary School NW7? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Regrouting in Mill Hill
Before any work starts, the tiles are checked. Loose or hollow tiles are pointed out first, since new grout can’t fix a problem underneath. With sound tiles, regrouting is a tidy, lasting improvement. We’re often asked to deal with grout in corners that has cracked and grout in a colour the owner wants to change, on tiled floors, kitchen splashbacks and shower walls.
London homes include a lot of flats, conversions and mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Mill Hill, that’s a good reason to put tired sealant and grout right early.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What happens if it’s left?
With regrouting, your tiles stay where they are. Retiling is a much bigger job: stripping, making good, new tiles and new grout, and often a few days without a shower. When the tiles are fine, it’s the sensible first step. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Mill Hill, the repair is bigger than a sealant job.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Mill Hill: your questions answered
Do you work for landlords with property near Mill Hill Broadway station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Can worn sealant in a flat in Mill Hill cause a leak downstairs?
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.
Do you come to Mill Hill?
We do. Our applicators work in Mill Hill.
How long will you be here?
Typically it takes a few hours for a shower enclosure, longer for a whole room. Bigger jobs take longer, and we will say how long yours will take.
Do you guarantee regrouting?
You get our 12-month guarantee on every job. We are also fully insured.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Where do you work from?
Mr Mastic is based in Crawley. We cover Mill Hill and the rest of Greater London, along with the rest of our area.
How much does regrouting cost in Mill Hill?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How the job changes by surface
Wet rooms
Regrouting a wet room helps keep water on the surface of the tiles. It can’t fix waterproofing below the tiles.
Bathroom floors
Grout on a floor is walked on as well as wetted. It wears and darkens over time.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours, or longer for a fully tiled room. In Mill Hill, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We agree the area to be regrouted and point out any loose tiles.
- We remove the old grout carefully.
- Dust is cleared from every joint.
- The new grout goes in, then the tile faces are cleaned.
- We renew the silicone at the corners and edges.
Preparing for the visit
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive
Ask for a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Advice
When to call us in Mill Hill
Most grout is porous, so it soaks up water, soap and dirt. Over time it stains, softens and starts to crumble, especially in a shower that’s used every day.
Look out for these signs:
- Floor grout that won’t come clean
- Cracked grout along the bath or tray
- Shower grout that has worn away
- Splashback grout that has darkened
Rented homes near Mill Hill Broadway station change hands often, and a regrout while the flat is empty is quicker than working around a tenant.
Questions to ask before booking
- How the joint is cleaned and prepared
- What product goes in the joint
- What guarantee comes with the work
- How much experience the applicator has
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Don’t ignore a tile that feels loose
- Give the walls a quick rinse after use
- Keep an eye on the silicone along the edges
- Do not use strong acidic cleaners on grout
We’ll tell you when the area can be used again. Please follow it, and avoid scrubbing the new grout hard for the first few days.
Grout that is washing out of a shower shouldn’t be left. Every shower pushes more water into the gaps, and that water can reach the wall or the floor below.
When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Tiles that are chipped or split
- Movement in a stud wall or floor
- Tiles that have come away from the wall
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
