Commercial sealant in Greenhill, done properly
Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. Products include Arbo and Everbuild sealants, applied by ARBOMaster approved applicators. We’re often asked to deal with leaking joints in shower rooms and changing areas and whole floors of tired en suites, on student & care accommodation, welfare facilities and retail & leisure sites.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Greenhill cannot close.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the number of rooms, and we tell you how long to leave it before we go. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First we visit and agree the scope, the sequence and the working hours.
- Room by room, we protect the area and remove all the old sealant.
- We clean the joints, treat any mould and let them dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Rooms are checked and returned with a cure time so staff know when to use them.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
- Let us know about earlier repairs to the joints

Questions from Greenhill
Can you help a landlord with a rental near Harrow-on-the-Hill station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Is parking a problem for a job in Greenhill?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What should I tell you?
Tell us what needs doing and where, with pictures by email if possible. If we need more, we will ask.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
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.
How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours per room, so whole buildings are phased. We will tell you when we quote.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What happens if it’s left?
Sealant work is quick by the room: the job takes a few hours per room, so whole buildings are phased. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
What you get with us
- Colour picked to suit the job
- Every job guaranteed for a year
- Approved under the ARBOMaster scheme
- White, clear, grey or coloured to suit, where the product allows

How we quote for commercial sealant
You will get a clear quote before we start. It’s based on:
- Mould in or behind the old joints
- Working hours on commercial sites
- How easy the joints are to reach
- The amount of work
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Where the job is, and your postcode
- A few pictures by email, if you can
- The rough size of the job
- The type of property
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or send us an email.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ask cleaners to go gently on the silicone
- Schedule work around occupancy
- Do not leave a failed joint until the next refurbishment
- Add sealant to your planned maintenance checks
We give a cure time for every area we finish, which is generally around 24 hours. Make sure housekeeping or cleaning staff know it so nobody showers or cleans the joint too early.
A room that can’t be let or used is lost income. Small sealant faults caught early can be fixed between bookings or tenancies, before they become leaks that take the room out of use.
When to call us in Greenhill
Wet rooms and accessible showers are designed for the whole floor to get wet, so floor-to-wall joints take standing water. A failed joint there can soon let water into the floor or walls.
Common reasons people contact us are:
- Failed joints in office kitchens and tea points
- Split sealant where wet room floors meet walls
- Black, stained silicone in guest bathrooms
- Silicone laid over old silicone by a previous contractor
Schools such as Saint Jerome Church of England Bilingual School are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours.

Commercial buildings in Greenhill
London’s water is hard, so limescale builds up on sealant, grout and fittings. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
As a London address, Greenhill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you look after a church, hall or community building such as Church of St John the Baptist, halls and community kitchens see heavy use, and their sealant shows it.
