How we handle commercial sealant in Arnos Grove
Guest bathrooms are cleaned every day and used by different people every night, so sealant there has a hard life. We work through rooms in batches, so only a few are out of use at once. If you are dealing with too many rooms to reseal without closing the building and sealant failing again soon after quick repairs, we can put it right, whatever the surface.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Arnos Grove, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Looking after it afterwards
To keep the joints looking good and working properly:
- Tell cleaning staff when each room can be used
- Plan resealing around quiet periods
- Check extract fans are actually running
- Don’t leave a failed joint until the next refurbishment
Extract fans need to work. In internal bathrooms, a weak or broken fan lets moisture linger, and that is what keeps mould away.
Mould in shared washrooms gets noticed and talked about. The longer it’s left, the deeper it grows into the silicone, and only replacement fixes it.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Commercial buildings in Arnos Grove
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. London has hard water, so limescale builds up on sealant, grout and fittings.
For site and facilities teams at buildings such as Bowes Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Letting a property close to New Southgate station? Then several rental properties can be resealed on one programme.

Common questions in Arnos Grove
Is Arnos Grove in your area for commercial sealant?
Yes, Arnos Grove is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Can parking be tricky for a visit in Arnos Grove?
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.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Can you reseal every bathroom in a hotel?
Yes. Larger jobs are planned as a room-by-room or floor-by-floor programme, so only part of the building is affected at once.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Does commercial work come with a guarantee?
Yes, with our 12-month guarantee. Regular gentle cleaning and working extraction help the sealant last.

Advice
When to call us in Arnos Grove
Internal washrooms and en suites without a window rely entirely on extraction, and where extraction is poor, damp hangs around. That’s when black mould sets into the bead.
Most people get in touch when they notice something like this:
- Rental bathrooms that need resealing between tenants
- Split sealant around staff kitchen worktops and sinks
- Mouldy washroom sealant that staff and guests notice
- Washrooms that need sorting before an inspection
Community buildings like Syro-Malabar Catholic Church of London are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.
Comparing quotes
- What the quote includes, VAT included or not
- Is the old sealant removed completely?
- Who turns up on the day
- Are they insured?
What happens if it’s left?
Fixing rooms one complaint at a time is the slow way. A planned programme deals with every room in order, with less disruption and one clear quote. In London conversions, one flat’s bathroom is often above another flat’s ceiling, 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.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
What you get with us
- Any old sealant cut out fully, not covered over
- More than 20 years in sealant work
