Clapham questions
Do you cover Clapham for bathroom resealing?
Yes. We work across London and the South East, and Clapham is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
Is Clapham within the area you cover?
Yes, Clapham is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Are you fully insured?
Yes. Full insurance covers our work.
What does bathroom resealing cost?
Size, access and the old material all affect the cost. Ask us for a quote.
My sealant has gone black. Can you sort it?
Yes. Mould inside the bead rarely cleans out for good, so the bead comes out, the joint is treated and new anti-fungal silicone goes in.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How we handle bathroom resealing in Clapham
Sealant is the soft line between a bath, shower or worktop and the wall. Once it cracks or goes mouldy, water starts to find its way through and into the wall or floor. Every trace of the old sealant is taken out and replaced with anti-fungal sanitary silicone. If you have lumpy, uneven sealant from a DIY attempt and new sealant laid over old sealant that is now lifting, we can help, on kitchen worktops & upstands, baths and wet rooms alike.
Around Clapham, it’s houses and cottages rather than flats. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Landlords, agents and businesses in Clapham
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Common problems we fix in Clapham
Sealing over old silicone is one of the commonest mistakes we find. New silicone won’t bond to old silicone, so it peels, leaks and hides mould behind it.
Common reasons people contact us include:
- Lumpy, uneven sealant from a DIY attempt
- A reseal done over the top of the old bead
- Gaps where the bath or tray has moved
- Damp behind the bath or under the tray
Schools such as Clapham and Patching CofE Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- What insurance they hold
- Which colour the sealant will be
- Who turns up on the day
- When the joint can take water or movement
Bathrooms and kitchens in Clapham
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.
If you live in an older home near The Parish Church of St Mary, walls and floors in older homes can move, and sealant and grout show it first. Letting a property close to Goring-By-Sea station? Then a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

Aftercare tips
After the cure time, these simple habits help:
- Clean with a mild bathroom cleaner and a soft cloth
- Keep bottles off the sealant line
- Squeegee the walls and tray after use
- Open a window or run the fan so the room dries
Have a look at the joints every few months. Small splits and lifting ends are easy to catch early, so if something does not look right, just ring 0345 464 0079 or email us.
Don’t wait for a refit to deal with failed sealant. Like paintwork, sealant needs renewing from time to time, and replacing it when it fails protects the rest of the room.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes two to three hours for a typical bath, depending on how much old sealant there is. In a small place like Clapham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- The bead is tooled smooth and you are told the cure time, normally around 24 hours.
Preparing for the visit
- Mention any tricky access
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules

How we quote for bathroom resealing
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Any mould that needs treating
- The number of rooms or windows
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Helping us quote
To make quoting easier, please include:
- Photos by email, if that is easy
- The rough size of the job
- The address or postcode of the job
- Any access issues, like height or stairs
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or drop us an email.
