How we handle regrouting in Garston
Most regrouting jobs include resealing too. Grout belongs between tiles, but corners and edges move, so they need flexible silicone instead. Renewing both together means nothing is left half-done. If you’re dealing with gaps where the shower grout has gone and grout in a colour the owner wants to change, we can help, on bathroom wall tiles, wet rooms and shower walls alike.
In a smaller place like Garston, homes are mostly houses and bungalows rather than flats, some older and some much newer. Sealant and grout wear out here just as they do in a big town.
You get a one-year guarantee, the same in Garston as everywhere else we work.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Garston questions
Is Garston within the area you cover?
Yes. Garston is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Garston station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Will the sealant be renewed as well as the grout?
We normally do. Fresh grout next to old, mouldy silicone would look odd and could still leak.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
How soon can the shower be used after regrouting?
We give you a time before we leave. The wait depends on the products and conditions so please stick to it.
Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Do not ignore a tile that feels loose
- Use gentle cleaners on grout
- Keep harsh bleach and acid cleaners off the grout
- Keep an eye on the silicone along the edges
Use a gentle cleaner on the grout with a soft brush. Avoid neat bleach and strong acid descalers because they wear grout away.
Fixing grout early is a small job. Left, the same problem can let water through so it’s worth dealing with as soon as you spot it.

Common problems we fix in Garston
Grout that was put in corners cracks because those joints flex. They need flexible sealant, and if they’re grouted, a crack soon lets water in.
If you can see any of these, it’s time to have the joints looked at:
- Stained grout that cleaning won’t shift
- Discoloured grout on otherwise sound tiles
- A grout colour that no longer suits the room
- Gaps where the shower grout has gone
If you look after a building such as The Grove Academy, 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.

Bathrooms and kitchens in Garston
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Garston station? Then stained grout drags a rental down, and regrouting between lets puts that right. Homes close to Stanborough Park Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Different surfaces, different methods
Bathroom wall tiles
Grout by the basin and bath tends to mark first. We can regroute just those areas or the whole wall.
Corners and edges
Where tiles meet a bath, tray or worktop, the joint is sealed. Grout in that joint wouldn’t last.
Why act early in Garston
Grouting over old grout rarely lasts. A thin skin on top tends to break off. Raking out to a consistent depth gives the new grout something to hold. Around Garston, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
