Regrouting in Cooper's Green
Grout is the filler between your tiles, while sealant goes where tiles meet a bath, tray or worktop. Once grout starts to crack or wash away, 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. Typical jobs include kitchen splashback grout stained by grease and cracked grout along the bath or tray, on kitchen splashbacks, wet rooms and bathroom floors.
Somewhere as small as Cooper's Green, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.

Why deal with it now?
Grouting over old grout rarely lasts. It sits thinly on top and soon flakes away, taking any repair with it. Removing the old grout to an even depth lets the new grout key in properly. Where a wall is exposed, as many are in small places like Cooper's Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start.
Why choose Mr Mastic in Cooper's Green
- Old sealant always removed completely
- Every job guaranteed for a year
- An ARBOMaster approved applicator
- Anti-fungal silicone where joints get wet
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Wipe or squeegee the shower walls
- Look at the sealant in the corners now and then
- Rinse soap off the tiles after each shower
- Avoid neat bleach and strong acid descalers on grout
Use a gentle cleaner on the grout with a soft brush. Avoid neat bleach and strong acid descalers, as they can break grout down.
Leaving failed grout can mean tiles come loose. Once that happens, regrouting won’t fix it so early action pays.
Do you need regrouting in Cooper's Green?
Hard water and soap leave a film on grout that’s hard to shift. The grout beneath can stain and weaken, which is when replacing it makes sense.
The problems people generally mention when they call include:
- Floor grout that has worn and darkened
- Grout washed out of a shower
- Grout that stays dark however much it’s cleaned
- Splashback grout that has darkened
If you look after a building such as Howe Dell Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- How the surfaces are prepared before sealing
- Is VAT in the price?
- What the cure time is
- The length of the guarantee
What regrouting looks like in Cooper's Green
Cooper's Green is part of Hatfield, one of the post-war new towns. Many homes date from the post-war decades, so bathrooms and kitchens may be on their second or third set of sealant. Sealant laid over old sealant never bonds properly, so it all has to come out. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For landlords with property near Hatfield station, a regrout while the flat is empty is quicker than working around a tenant.

Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree what’s being done and flag any loose tiles.
- Grout is raked out without chipping the tiles.
- 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.

Quotes for regrouting in Cooper's Green
Every job gets its own quote. These are the things that affect it:
- The number of rooms or windows
- The number and length of the joints
- Access and height
- Whether there’s mould to deal with
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- What’s wrong with the joints now
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
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.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Questions from Cooper's Green
Will you come out to Cooper's Green?
Yes, Cooper's Green is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Hatfield station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can you change the grout colour?
Yes, plenty of people choose to. A darker grout hides marks better, while lighter grout brightens a room.
Will regrouting fix loose tiles?
New grout can’t hold loose tiles in place. We check the tiles first and tell you if any are loose or hollow, so you can decide what to do.
What goes in the corners, grout or silicone?
Flexible sealant. Grout is for the joints between tiles and moving joints need sealant.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you reseal at the same time?
In most cases, yes. The corners and edges should be silicone and doing both at once leaves everything sound.
Different surfaces, different methods
Bathroom wall tiles
Walls outside the shower get less water but still stain and crack. Regrouting brings them back in line.
Kitchen splashbacks
A splashback can be regrouted without touching the worktop. The worktop edge is finished with silicone.
