Commercial sealant contractors across WC1X: what to expect
On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. We work on kitchen worktops and splashbacks, external facade joints and window and door perimeters, and what we are called in for most is layers of sealant, all of them failing and shrunken sealant along kitchen worktops and splashbacks.
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Where parts of the building must stay open, the work is phased.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
What you will pay
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Shops, offices and hotels in WC1X
In WC1X, much commercial sealant work follows refits in shops, offices and hotels in places such as Holborn and Clerkenwell. Where the joint is on show, a colour that suits the finish is part of the job.
The South East has large numbers of business parks and industrial estates, especially around the motorway corridors, and we cover WC1X along with the rest of the region.
Holborn: In hotels such as The Bryson Hotel, less than half a mile to the north-east of Holborn, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. Occupiers with premises at both Grand Vitesse Industrial Estate and Southwark Bridge Business Centre could have the sealant at each handled under one quote.
Surface by surface
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.
Movement joints in walls and floors
Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it.
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Deal with small splits before they become leaks
- Log reseals in the O&M or maintenance records
- Brief cleaning contractors to avoid scourers and blades on sealant
- Check the asbestos register before anyone disturbs old sealant in an older building
We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are.
For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
What happens if it’s left?
It can be tempting to hold sealant work back until the next refurbishment. For internal joints that are only cosmetic, that can make sense, but a joint letting water in now keeps doing damage until the refurb arrives. Splitting the scope into now and later is often the sensible compromise.
What your quote should include
- The named product and why it was chosen
- How long is the guarantee, and what does it include?
- Their plan for phasing and protecting the area
- Whether old or failed sealant will be cut out, not overlaid
Why it fails
No sealant joint is permanent. Its life comes down to movement, UV and weather, how it’s cleaned, how much traffic passes it and what was used in the first place. In commercial buildings those factors tend to act together, which is why regular inspection pays.
These are often picked up first by site or facilities staff:
- Layers of sealant, all of them failing
- Weathered facade sealant that no longer flexes
- Window and door perimeter joints that have cracked open
- Untidy joints in a reception, shop floor or lobby
Questions about WC1X
Do you take on multi-site sealant work?
Yes. Send a list of addresses and what’s needed at each, and fixed prices follow, with a suggested sequence.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Do you check for asbestos before removing sealant?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Is WC1X in your area?
Yes. WC1X falls within our area, and you can ring 01277 525 020 or send details through our quote form to get started.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
