Bathrooms and kitchens in Merton Park
Merton Park has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
For site and facilities teams at buildings such as Merton Park Primary School, 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. For an older house near a landmark such as St Mary's Church, walls and floors in older homes can move, and sealant and grout show it first.

Regrouting for homes and businesses in Merton Park
Grout is the filler between your tiles, and sealant is what goes along the bath, tray or worktop. When grout cracks or washes out, water has a way in behind the tiling. Our job is to rake it out and put new grout in, then reseal the corners and edges. We work on tiled floors, kitchen splashbacks and bathroom wall tiles, and common reasons people get in touch are splashback grout that has darkened and corners filled with grout instead of silicone.
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.
Big or small, you get the same 12-month guarantee.

What else we do in Merton Park
How the job changes by surface
Shower walls
Shower walls are the most common area we regrout. Gaps here let water get behind the tiling.
Wet rooms
Regrouting a wet room helps keep water on the surface of the tiles. It cannot fix waterproofing below the tiles.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Tiles that have come away from the wall
- A structure that flexes behind the tiles
- Failed tanking or waterproofing under the tiles
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
Surfaces we seal
- Tiled floors
- Bathroom floors
- Kitchen splashbacks
- Bathroom wall tiles
- Wet rooms
- Shower walls
What we’re called out for in Merton Park
Hard water and soap leave a film on grout that’s hard to shift. The grout beneath can stain and weaken, and at that point, new grout is the better answer.
It’s worth asking for a quote if you see:
- Discoloured grout on otherwise sound tiles
- Greasy, stained grout behind the hob
- Cracked or crumbling grout lines
- Shower grout that has worn away
For landlords with property near South Merton station, a regrout while the flat is empty is quicker than working around a tenant.

Keeping the joints in good condition
Looking after new joints is easy:
- Rinse the tiles after showering
- Look at the sealant in the corners now and then
- Skip wire brushes and scourers
- Run the extractor fan during and after a shower
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 keep the room ventilated.
Leaving failed grout can mean tiles come loose. Once that happens, regrouting will not fix it so early action pays.
How it works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a shower enclosure, longer for a whole room. In Merton Park, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Every tile area is checked for hollow or loose tiles first.
- The old grout is removed to an even depth.
- We vacuum the joints so the new grout bonds.
- New grout is pressed into the joints and the tiles are cleaned.
- Silicone goes into the corners and along the edges.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules

DIY sealant or a professional job?
The difference is mostly in the preparation and the 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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Merton Park questions
Do you work for hotels and guest houses in Merton Park?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
I let a flat near South Merton station. Can you help?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is resealing included with regrouting?
Normally we do both. Grout fills tile gaps and sealant handles the moving joints, so we renew both and it’s all in the quote.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
How long does regrouting take?
As a guide, most jobs take a few hours, or longer for a fully tiled room. Larger jobs naturally take longer, and we will tell you how long to expect.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Why act early in Merton Park
Once grout cracks, water can get behind the tiling. Leave it, and the adhesive or the wall behind can suffer, which turns a regrout into a retile. Sorting it early keeps the job simple. In a flat in Merton Park, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
