How bathroom resealing works in SO21
Across SO21, the joints we reseal are the ones that fail in any home: the long edge of the bath, the base of the shower tray, the back of the basin and the line along the worktop. Every joint is cut out, cleaned and left dry before it’s resealed. We are often asked to deal with lumpy, uneven sealant from a DIY attempt and black mould in the silicone that won’t clean off, across baths, sinks & splashbacks and kitchen worktops & upstands.
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take around two hours for one bath or shower, longer for a whole bathroom.
- First the area is protected and every bit of old sealant removed, including the film left on the tiles.
- We clean and degrease the joint and treat any mould.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- We clear away and tell you when it can get wet, usually after around 24 hours.

Bathroom resealing across SO21: local notes
From Winchester, Allbrook and Highcliffe to its smaller places, homes across SO21 have bathrooms and kitchens of every age. Sealant and grout wear out in all of them, whether it’s a family bathroom, a rented flat or a hotel en suite.
London and the South East have homes from every era, from period terraces to post-war new towns and new estates. Each needs the right sealant for its age and materials, wherever it is in SO21.
Colden Common: For site and facilities teams at buildings such as Colden Common Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Church of the Holy Trinity include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
Signs you need bathroom resealing
Mould is the reason many people want their sealant replaced. Steamy rooms that do not dry out give mould all the damp it needs, and mould that has grown into the silicone usually will not clean off.
The most common problems we see are:
- Mouldy sealant that has gone black
- New sealant laid over old sealant that is now lifting
- Leaks into the floor or ceiling below
- A joint torn by a bath that flexes
What affects the quote in SO21
There’s no set price list, because jobs vary so much. The quote depends on:
- The type of sealant required
- Access and height
- Working hours on commercial sites
- Mould in or behind the old joints
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
What we need to know
To help us quote quickly, please include:
- Where the property is
- Photos by email, if that is easy

Why deal with it now?
Fresh sealant smartens a bathroom or kitchen with very little disruption, which matters if you are letting a property or selling it. A smeared, uneven DIY bead does the opposite, and it’s harder to put right later.
What your quote should include
- Whether you can choose the colour
- Who turns up on the day
- What preparation is included
- The length of the guarantee
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep an eye on the corners, where splits start
- Give the silicone its full cure time
- Squeegee the walls and tray after use
- Dry worktop joints after washing up
Keep bottles and razors off the sealant line, because they trap water against the silicone. A quick squeegee after showering keeps water from sitting on the joint.
Small signs come before a leak: lifting ends, gaps, dark shadows under the bead or a stain downstairs. Any of these means the joint needs attention.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
FAQs for SO21
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.
Where is Mr Mastic based?
We work from Crawley. We cover SO21 and the rest of Hampshire.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Is it OK to put new sealant on top of the old bead?
No. Fresh silicone can’t stick to the old bead, so it peels away and hides mould and water. We always take the old sealant out completely.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
