DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What happens if it’s left?
Sorting it now is quick: the work takes two to three hours for a typical bath, depending on how much old sealant there is. Left until water gets through, the job can grow to lifting panels, drying out and decorating. In a small place like Alverstoke, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Common problems we fix in Alverstoke
Silicone doesn’t last for ever. Daily water, heat and cleaning products take their toll over the years, so its life depends on how the room is used, cleaned and aired.
It’s worth asking for a quote if you see:
- Black spots spreading through the bead
- Damp behind the bath or under the tray
- Shrunken sealant along the back of a worktop
- Cracked, shrunken or lifting silicone
For landlords with property near Portsmouth Harbour station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
What to look for in a quote

Your questions about bathroom resealing in Alverstoke
Is Alverstoke within the area you cover?
Yes, Alverstoke is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Portsmouth Harbour station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Are you fully insured?
Yes. We are fully insured.
How long does a bath or shower reseal take?
It takes a couple of hours for a single bath or shower. You’ll know how long to expect before any work starts.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
How much does bathroom resealing cost in Alverstoke?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
Landlords, agents and businesses in Alverstoke
Landlords and agents in Alverstoke can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Keep bottles off the sealant line
- Open a window or run the fan so the room dries
- Never pick at the silicone with a blade
- Use gentle cleaners on the silicone
Treat the new bead gently when you clean: warm soapy water and a soft cloth do the job. Scourers and blades can nick the surface, and a nicked bead lets mould in sooner.
Small signs come before a leak: lifting ends, gaps, dark shadows under the bead or a stain downstairs. If you spot one, it’s time to reseal.
What sealant work cannot fix
It helps to know what we can’t do:
- Water coming from the plumbing rather than the joint
- Cracks in the tray itself rather than the joint
- A tray that rocks until it’s re-bedded
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
Joints and surfaces we work on

Alverstoke homes and their sealant
Alverstoke is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you look after a building such as Alverstoke Community Infant School, we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to The Little Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
Alverstoke is about 2 miles south of Gosport, in Hampshire. Alverstoke gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Across Hampshire, we cover 683 places, Alverstoke among them.

What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a morning or an afternoon for most single baths and showers. Somewhere as small as Alverstoke, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, each joint is checked for movement and signs of water.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- The joint is cleaned, degreased and treated for mould.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- We tool the bead to a neat finish and give you the cure time, usually around 24 hours.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before
