About our fire stopping in Postcombe
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you’re dealing with seals that don’t match their tested detail and snag lists that include open service penetrations, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Postcombe, that means joint design, primers and backing rod as standard.
Rural conversions around Postcombe can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Fire stopping around Postcombe: points for this area
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Central London is about 40 miles from Postcombe. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
Wherever services are added at a hospital such as Thame Community Hospital, 3.8 miles north of Postcombe, the compartment line has to be made good with the specified product. For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing.
Postcombe is about 4 miles south of Thame, in Oxfordshire. Commercial clients in Postcombe can call on us for service penetrations, as part of our coverage of Oxfordshire. 423 places across Oxfordshire fall within our area, Postcombe among them.

How the job changes by surface
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.
Metal pipes
Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.
What sets the cost
These are the things that shape the price:
- Whether old sealant has to be cut out first
- The total length or number of joints
- Phasing around occupants
- Joint width, depth and condition
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Any dates the work must fit around
- Any specification or named product
- Clear photographs of the problem areas
- Anything awkward about access or site hours
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email us if you’d rather talk the job through.
When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking a single visit for a short list of penetrations, or a phased programme for a whole building. Smaller jobs around Postcombe can be grouped with others nearby. You will have a fixed quote before work starts.
- We ask for the product and detail your designer has specified.

Postcombe: questions and answers
Is a smaller place like Postcombe outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
What happens to BS 476 references for fire stopping in Postcombe?
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.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Do you offer coloured sealant?
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 will confirm the colours available for the specified product.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Why deal with it now?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. Converted and older buildings near places like Postcombe tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Pricing service penetrations depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
