Fire stopping in Leigh Green
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal, not a rule of thumb. Site teams most often ask us about expanding foam used as fire stopping and fire-stopping items raised at inspection or handover, on joints between fire-resisting walls and floors, cable penetrations and small duct penetrations where the tested detail allows. Whoever orders the work in Leigh Green, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Barn and farm-building conversions near places like Leigh Green often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Why deal with it now?
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. One visit to deal with every failing joint makes more sense than several trips to a place like Leigh Green. Send photographs of each area and we will quote for the lot.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Leigh Green can sit alongside others in a wider programme across Kent.
Different surfaces, different methods
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically and tell you about openings outside the list.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork typically needs a different solution set by the designer.
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. Rural sites near Leigh Green may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned 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.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Flag any permit to work we will need
- Share your working hours and any access restrictions

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Fire stopping in Leigh Green: the local picture
For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Leigh Green is about 46 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
In a school such as Tenterden Church of England Junior School, fire-rated sealant goes in around service penetrations where it is specified. Office fit-outs on sites such as Pickhill Business Centre, 1.1 miles to the south-west of Leigh Green, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Older community buildings such as Parish Church of St Mildred that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Leigh Green: questions and answers
Do you work on fire-rated sealing in hotels in Leigh Green?
Yes, where fire-rated sealant is the specified product. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
How does the move away from BS 476 affect penetration seals in Leigh Green?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Is the work guaranteed?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
How long does a job like this take?
That varies with the scale of the job, though a typical visit typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.
How long do sealant joints last?
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.
Looking after the joints
To get the most from the new sealant:
- Include service cupboards in routine inspections
- Agree the fire-stopping specification before services go in
- Arrange inspection before areas are covered up
- Foam or ordinary sealant is never a fire-seal repair
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
