Why it’s worth doing now in Canonbury
In a building with rooms above rooms, a failed shower seal can soon show on a ceiling below. That means a second room out of use and a repair to pay for. A reseal now avoids that. In a flat in Canonbury, 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.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Commercial sealant in Canonbury
Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. We are often asked to deal with sealant failing again soon after quick repairs and black, stained silicone in guest bathrooms, on student & care accommodation, office washrooms & kitchens and hotel bathrooms.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Canonbury, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
Whatever the size of the job, you get the same 12-month guarantee.

What else we do in Canonbury
Common problems we fix in Canonbury
Plenty of commercial bathrooms have no window at all, so if the fan is weak, steam lingers and the sealant stays damp. That’s when black mould sets into the bead.
Keep an eye out for these signs:
- Mouldy washroom sealant that staff and guests notice
- Split sealant around staff kitchen worktops and sinks
- Leaking joints in shower rooms and changing areas
- Whole floors of tired en suites
If you let a flat or house near Canonbury station, sealant work can be quoted for a single flat or a whole portfolio.

Commercial sealant around Canonbury
There are hotels and other places to stay in and around Canonbury. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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.
Schools such as Rotherfield Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Canonbury is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

DIY sealant or a professional job?
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.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Canonbury questions
Do you work for landlords with property near Canonbury station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Do you work for hotels and guest houses in Canonbury?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months, wherever you are.
Can you match the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
How long do rooms need to be out of use?
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.
The process
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. Most jobs take as long as the scope needs, from one welfare room to a full building. In Canonbury, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints

What sealant work can’t fix
In fairness, there are a few things sealant won’t fix:
- A shower tray, bath or basin that is cracked or broken
- Faulty shower valves and leaking traps
- Certifying fire stopping or building compliance
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

How we quote for commercial sealant
Every job gets its own quote. These are the things that affect it:
- Any working-time requirements on site
- The amount of work
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
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. You will know the price before we begin.
Helping us quote
To make quoting easier, please include:
- Photos by email, if that’s easy
- Where the job is, and your postcode
- How we’d reach the joints
- Any previous sealing or DIY work
Need a quote? Please call 0345 464 0079 or drop us an email and tell us about the job. We’ll explain what we’d do and send you a clear quote before we start.
