How we handle commercial sealant in East Sheen
Mr Mastic brings more than 20 years’ experience to commercial sites, and we’re fully insured and ARBOMaster approved. Tell us what paperwork your site needs, such as RAMS or insurance details, and we will confirm what we can provide. We’re often asked to deal with repeated reseals that don’t last and large numbers of bathrooms needing the same work, across office washrooms & kitchens, hotel bathrooms and rental portfolios.
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 East Sheen needs to stay open, work can be planned outside normal hours.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Plan resealing around quiet periods
- Include the silicone on your room checklists
- Keep strong chemicals and scourers off the joints
- Keep a record of which rooms were resealed and when
Extract fans need to work. Where a room has no window, the fan is what dries it out, and mould comes back faster without it.
Mould in shared washrooms gets noticed and talked about. The longer it’s left, the deeper it grows into the silicone, so the fix is replacement.

Why it’s worth doing now in East Sheen
Fixing rooms one complaint at a time is the slow way. A planned programme deals with every room in order, keeping disruption down and costs clear. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.
What you get with us
- More than 20 years in sealant work
- Any old sealant cut out fully, not covered over
- A choice of colours where the product allows
- Tidy, careful work
What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It usually takes a morning for a small washroom, and a planned programme for bigger sites. In a London area like East Sheen, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- The first visit is a look round the site to agree the scope.
- We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
- Areas are protected and the failed sealant removed.
- Joints are dried, then resealed and tooled neatly.
- We let your team know the cure time for every area.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules

Commercial buildings in East Sheen
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, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Schools such as Thomson House School are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours. As a London address, East Sheen can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

East Sheen questions
Do you work for landlords with property near Mortlake station?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is parking a problem for a job in East Sheen?
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 reseal every bathroom in a hotel?
Yes. Our team has more than 20 years’ experience, and large programmes are planned around how the building is used.
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.
Do you offer different sealant colours?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long does the job take?
That depends on the amount of work, but most jobs take a few hours per room, so whole buildings are phased. We’ll tell you when we quote.
What does commercial sealant cost?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email and let us know what needs doing and where.
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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Faulty shower valves and leaking traps
- Fire risk assessments or certification
- Water damage behind the tiles that needs a tiler or builder
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

Do you need commercial sealant in East Sheen?
Heavy use means more movement: different weights, constant use and daily cleaning. If a tray flexes, the sealant around it splits.
Most people get in touch after spotting something like this:
- Rental bathrooms that need resealing between tenants
- Whole floors of tired en suites
- Worktop sealant that has shrunk and stained
- Sealant failing again soon after quick repairs
Letting a property close to Mortlake station? Then several rental properties can be resealed on one programme.
