Commercial sealant in Highbury
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. Products include Arbo and Everbuild sealants, applied by ARBOMaster approved applicators. We’re often asked to deal with leaks from showers into rooms or ceilings below and tired sealant ahead of a health and safety audit, on rental portfolios, student & care accommodation and office washrooms & kitchens.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Highbury cannot close.
All our work comes with a 12-month guarantee, wherever you are in Greater London.

Highbury: your questions answered
I let a flat near Canonbury station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you work in hotels near Highbury?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
What should I tell you?
Tell us what needs doing and where, plus pictures if you have them. We’ll ask anything else we need to know.
How soon can a room be used after resealing?
Plan for around 24 hours, or the cure time we give for that area. A room-by-room programme keeps only a few rooms out at once.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you come to Highbury?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Highbury included.
Can you start early or work out of hours?
Early starts and out-of-hours work can be arranged. Tell us what you need when you ask for a quote.
How we quote for commercial sealant
Jobs vary more than people expect. The main factors:
- Access and height
- The number of rooms or windows
- Working hours on commercial sites
- The amount of work
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.
Helping us quote
Photos help, but a description is a good start. Please mention:
- What’s wrong with the joints now
- The type of property
- How many joints, rooms or windows are involved
- Where the job is, and your postcode
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Looking after it afterwards
To keep the joints looking good and working properly:
- Book larger programmes for quieter times of year
- Get split or lifting joints looked at early
- Add sealant to your planned maintenance checks
- Keep a record of which rooms were resealed and when
Add sealant checks to your planned maintenance. Checking joints alongside other room checks catches failures before they leak.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Dealing with the joint early stops that spread.
When to call us in Highbury
Heavy use means more movement: people of all sizes, daily cleaning and constant loading all work at the joint. If a tray flexes, the sealant around it splits.
If you can see any of these, it’s time to have the joints looked at:
- Water marks on ceilings under bathrooms
- Split sealant where wet room floors meet walls
- Large numbers of bathrooms needing the same work
- Washrooms that need sorting before an inspection
As a London address, Highbury can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before booking
- Whether you can choose the colour
- What product goes in the joint
- What insurance they hold
- Is the old sealant removed completely?
What happens if it’s left?
Before an inspection, audit or busy season, sealant is easy to overlook. Planning the work ahead means rooms are finished and cured in time, without a last-minute rush. In a flat in Highbury, 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.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on the number of rooms. For a job in Highbury, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We start by looking at the rooms and agreeing what’s needed.
- Working hours are agreed, including early starts or out-of-hours work where it 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.

London has hard water, which leaves limescale on sealant, grout and taps. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
If you look after a church, hall or community building such as Christ Church, any kitchen and washrooms need the same sealant care as any other building. If you let a flat or house near Canonbury station, sealant work can be quoted for a single flat or a whole portfolio.
