- Shrunken sealant along the back of a worktop
- Mouldy sealant that has gone black
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Bathroom resealing in Sunningwell, done properly
Before a bath is sealed, it’s filled with water. A full bath sits slightly lower than an empty one, so the new joint is not pulled apart the first time it’s used. Quick jobs often leave it out, and it makes a real difference. We work on baths, basins & vanity units and sinks & splashbacks, and the jobs we see most are a joint torn by a bath that flexes and black mould in the silicone that won’t clean off.
In a village or hamlet like Sunningwell, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Whatever the size of the job, you get the same 12-month guarantee in Sunningwell and across Oxfordshire.

Why act early in Sunningwell
Bleach and mould sprays may lighten black marks for a while, but where mould is inside the silicone it generally comes back. The lasting answer is to remove the bead and start again. Where a wall is exposed, as many are in small places like Sunningwell, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What bathroom resealing looks like in Sunningwell
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For site and facilities teams at buildings such as Sunningwell Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you live in an older home near Church of St Leonard, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you let a flat or house near Radley station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

- Next, the joint is cleaned and any mould is treated.
- We let it dry fully and fill the bath with water before sealing.

Sunningwell questions

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Sunningwell for bathroom resealing?
Yes, Sunningwell is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.
Does the resealing come with a guarantee?
Yes. Our 12-month guarantee covers every job, and we are ARBOMaster approved applicators.
Can new silicone go straight over the old?
No. Fresh silicone cannot stick to the old bead, so it lifts and traps water and mould underneath. We always take the old sealant out completely.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Sunningwell and the rest of Oxfordshire.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can you get rid of the black mould in my sealant?
Yes, we can. We strip the bead, treat the joint and lay new anti-fungal silicone.
What we can’t put right
To be straight with you, there are a few things sealant won’t fix:
- A cracked shower tray or bath (that needs repair or replacement)
- Damage behind the tiles that needs a tiler
- Failed grout lines across the wall
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Landlord and commercial work in Sunningwell
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Aftercare tips
Aftercare is simple:
- Do not let bottles sit on the bead
- Stick to a soft cloth and a mild cleaner
- Wait for the cure time we give you
- Never pick at the silicone with a blade
Wipe up standing water along the worktop joint. A dry joint lasts longer.
Small signs come before a leak: a corner lifting, a gap behind the bead, a dark line under the silicone or a damp patch on the ceiling below. Any of these means the joint needs attention.
