Fire stopping in Woodhall Farm
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. If you are dealing with fire stopping installed outside its tested range and open linear gaps along the top of fire-resisting walls, we can put it right, whatever the surface. Most enquiries from Woodhall Farm 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.
Buildings in a smaller place such as Woodhall Farm that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email drawings and photos and we’ll come back to it.

What affects the price in Woodhall Farm
Before we quote, we look at:
- Distance, for remote addresses
- Removal of failed or old sealant
- Backing rod, priming and other preparation
- Which sealant the job calls for
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.
What we need to price the job
However big the job, the same details help:
- A wide shot and a close-up of the area
- Drawings or a marked-up plan, if available
- The product your specification calls for
- Anything awkward about access or site hours
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email drawings and photos.
Diagnose, treat, sign off
Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. What matters most for a job in Woodhall Farm is a clear list of what needs doing, so send photos of each area. A fixed quote follows.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Let building users know which areas are affected
- Confirm the product named in the specification
- Let us know about inductions and permits

Questions we are asked in Woodhall Farm
Is Woodhall Farm too far out for you?
Not at all: smaller places are covered as well as 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.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Woodhall Farm?
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. Our part doesn’t change: the specified product, to its tested detail.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Fire stopping around Woodhall Farm: points for this area
There are several hotels within about 2 miles of Woodhall Farm. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. At about 24 miles from central London, Woodhall Farm is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.

Halls and meeting rooms at places like Alexandra Road Congregational Church sometimes gain new services, and any compartment wall crossed needs the specified seal.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Look above ceilings when tiles are lifted for other jobs
- Ask the designer to confirm details early on refits
- Check with the data sheet before painting over fire sealant
- Keep product data and details in the fire safety file
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.
What the job involves on each surface
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.
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 we work within it.
