Fire stopping in Chevening, done properly
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. If you’re dealing with old intumescent sealant that has split away and openings found when ceilings come down for a refit, we can help, whatever the surface. Most enquiries from Chevening 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.
For a smaller site near Chevening, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside 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 usually needs a different solution set by the designer and we flag that rather than guess.
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically.

When to call us in Chevening
Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access usually bring them to light.
What tends to prompt an enquiry:
- Builders’ foam or ordinary silicone in compartment walls
- Service penetrations left open after M&E works
- Seals that don’t match their tested detail
- Damaged fire seals in risers and voids
In a hotel such as Donnington Manor Hotel, 1.2 miles to the east of Chevening, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
Before you book anyone
- Whether old or failed sealant will be cut out, not overlaid
- What the guarantee covers, and for how long
- Do they follow the manufacturer’s priming guidance?
- Whether their applicators hold CSCS cards
Compartment walls and floors in Chevening
At about 17 miles from central London, Chevening is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around 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.
For a building at a site such as North Downs Business Park, 1.2 miles to the north-east of Chevening, a check of penetration seals after each fit-out is good practice. Schools such as Combe Bank School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Your questions answered
Is Chevening too small for you to travel to?
Not at all. Chevening is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is a hospital such as Sevenoaks Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
What changes on 2 September 2029?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, though transitional rules apply. Scotland follows its own Technical Handbook, including clause 2.1.14 on service penetrations.
Can you quote from photographs?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Do you seal openings left by new services?
Yes. Share the penetration schedule and product details and a fixed quote follows. We can follow the services contractor floor by floor keeping pace with the programme.
What we can’t put right
Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:
- Reviewing a building’s overall fire safety
- Openings that need collars, wraps, batts or boards rather than sealant
- Approving the work on behalf of building control
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

How a job runs
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off.

- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Before we start on site
- Tell staff and tenants when we’ll be in
- Arrange parking or a loading space

Advice
Keeping the joints sound
To get the most from the new sealant:
- Treat an open penetration as a priority repair
- Record which product was used where
- Agree the fire-stopping specification before services go in
- Foam or ordinary sealant is never a fire-seal repair
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and installation follows the programme.
Quoting for work in Chevening
Before we quote, we look at:
- How accessible the joints are
- Removal of failed or old sealant
- The total length or number of joints
- Site requirements such as inductions and permits
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
What to include in your enquiry
However big the job, the same details help:
- The type of building and who uses it
- Drawings or a marked-up plan, if available
- Your programme or deadline
- The asbestos register, for older buildings
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to give us a call on 01277 525 020 or send photos by email with what you know.
