Fire stopping near Kemsing
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Surface by surface
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork normally needs a different solution set by the designer.
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits, and any outside it are raised with you.
Fire stopping for commercial buildings in Kemsing
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. The enquiries we see most involve unsealed openings around new pipes and cables and fire sealant pulled out of the opening, across small duct penetrations where the tested detail allows, cable penetrations and joints between fire-resisting walls and floors. Most enquiries from Kemsing start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around Kemsing, penetration and linear seals tend to be one-building jobs. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Questions we’re asked in Kemsing
Is a smaller place like Kemsing outside your area?
No. Places such as Kemsing are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
What does the BS 476 change mean for fire-rated sealant in Kemsing?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Is your workmanship covered by a guarantee?
Yes. Our workmanship is backed for 12 months.
Can staff carry on working while you’re here?
In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Honest limits
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Deciding what a wall or floor needs, which belongs to the designer
- Gaps in walls that were never built as compartment walls
- Reviewing a building’s overall fire safety
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.
Surfaces we seal
- Cable penetrations
- Pipe penetrations
- Linear gaps at wall heads
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
Do you need fire stopping in Kemsing?
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.
Clients typically get in touch after noticing something like this:
- Old intumescent sealant that has split away
- Snag lists that include open service penetrations
- Builders’ foam or ordinary silicone in compartment walls
- Openings found when ceilings come down for a refit
In a school such as Kemsing Primary School, fire-rated sealant goes in around service penetrations where it is specified.
What your quote should include
- How they handle RAMS and site documents
- Which product they’ll use, and why it suits the joint
- Will CSCS-carded applicators be on site?
- How the existing material will be dealt with
Penetration seals near Kemsing
In England, Approved Document B covers fire stopping of openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail. At about 19 miles from central London, Kemsing is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.
Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification. On a hospital site such as Sevenoaks Hospital (1.6 miles south-west of Kemsing), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Kemsing is about 2 miles north-east of Sevenoaks, in Kent. We cover Kemsing and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

From enquiry to sign-off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in 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. Work in places the size of Kemsing is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Warn occupants and staff about the work
- Tell us what induction or permit system the site runs
- Agree which areas must stay open
