Fire stopping for Cowfold sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What the job involves on each surface
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.
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.
Fire stopping in Cowfold
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. We work on cable penetrations, linear gaps at wall heads and service gaps in risers, and the failures we’re asked to look at most are penetration schedules that need working through and unsealed openings around new pipes and cables. Searching for sealant specialists in Cowfold? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around smaller places like Cowfold, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why act early in Cowfold
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down. One visit to deal with every failing joint makes more sense than several trips to a place like Cowfold. Photos of every joint help us quote for the whole job.
Pricing service penetrations depends on how many there are, their condition and the access. Ask us for a fixed quote.

Common questions from Cowfold clients
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Cowfold?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.
Can you work at a site such as Brook Farm Business Park, by Cowfold?
Yes. Estates, retail parks and business parks around Cowfold, Brook Farm Business Park among them, are all within reach. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Is colour matching possible?
Often, 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.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
What do you charge?
We don’t publish prices, as every site differs. Send photographs or drawings and we’ll price it at a fixed figure.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Our process
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For a building around Cowfold, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Let building users know which areas are affected
- Tell us what induction or permit system the site runs
- Share the asbestos register for older buildings
Getting a fixed quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Related advice
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Service penetrations in Cowfold buildings
At about 36 miles from central London, Cowfold is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. We install whatever has been specified, to the product’s tested detail.
Schools such as St Peter's CofE (Aided) Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. On a hospital site such as The Dene Hospital, 4.9 miles to the east of Cowfold, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. In a building such as Church of St Peter, any service penetration through a fire-resisting wall should be sealed to the specified detail.
