Clapham Junction Commercial Sealant
Washrooms, bathrooms and kitchens in Clapham Junction need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Mouldy washroom sealant that staff and guests notice
- Joints that need doing before an inspection or audit
- Water marks on ceilings under bathrooms
Why act early in Clapham Junction
Replacing a whole washroom takes time, money and several trades. When the fittings are sound, renewing the sealant brings it back with far less upheaval. We will tell you if we find anything that needs another trade. In a flat in Clapham Junction, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- 12-month guarantee on every job
- Sanitary silicone with an anti-fungal additive in wet areas
- We never seal over old sealant
- We’re fully insured
Commercial sealant in Clapham Junction
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. If you have joints that need doing before an inspection or audit and failed joints in office kitchens and tea points, we can help, on hotel bathrooms, student & care accommodation and retail & leisure sites alike.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Clapham Junction needs to stay open, work can be planned outside normal hours.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Your questions about commercial sealant in Clapham Junction
Is parking an issue for commercial sealant in Clapham Junction?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you help a landlord with a rental near Clapham Junction station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Is out-of-hours working possible?
Often, yes. Tell us your opening hours and quiet times, and we’ll see what can be arranged.
When can guests or staff use the shower again?
Usually after around 24 hours. We give a cure time for each area.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

Common problems we fix in Clapham Junction
In office kitchens and tea points, joints are wet and wiped all day, and grease and cleaning sprays break down sealant. The worktop and sink edges generally fail first.
The problems people normally mention when they call include:
- Shower leaks reaching the floor below
- Silicone laid over old silicone by a previous contractor
- Failed floor-level joints in accessible wet rooms
- Failed joints in office kitchens and tea points

Questions to ask before you book
- Whether VAT is included
- How the joint is cleaned and prepared
- Whether they seal over old material or remove it
- Who does the work, and how experienced they are
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Book larger programmes for quieter times of year
- Ask cleaners to go gently on the silicone
- Leave squeegees in busy showers
- Get split or lifting joints looked at early
Add sealant checks to your planned maintenance. A quick look at each bathroom when rooms are checked spots problems early.
It’s easier to plan a programme than to react to failures. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Workplaces and buildings in Clapham Junction
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
Community buildings like Clapham Welsh Presbyterian Church are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else. Clapham Junction is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
