How we handle fire stopping in Alfold
Facilities managers in Alfold often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. Site teams most often ask us about seals disturbed by maintenance and left open and fire sealant pulled out of the opening, on small duct penetrations where the tested detail allows, linear gaps at wall heads and joints between fire-resisting walls and floors. Whether you call it commercial sealant work, mastic application or joint sealing, in Alfold it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Barn and farm-building conversions near places like Alfold 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.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- File the specified details where the next contractor can find them
- Check risers and ceiling voids after each round of works
- Put resealing into every M&E and fit-out package
- Treat an open penetration as a priority repair
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
When to bring in a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
For managing agents and facilities managers
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Why deal with it now?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. Around Alfold, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we look at:
- The total length or number of joints
- Distance, for remote addresses
- Induction, permit and paperwork requirements
- Access and working height
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Details that help us quote
It doesn’t need to be a full survey. These details are enough to start:
- Whether the building will be occupied during the work
- Any specification or named product
- How the joints are reached, and at what height
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
FAQs: Alfold
Is a smaller place like Alfold outside your area?
Not at all. Alfold is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Is The Old Brickworks Industrial Estate, near Alfold, within your area?
Yes. Estates, retail parks and business parks around Alfold, The Old Brickworks Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. 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. Removing asbestos is a job for asbestos specialists, not us.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
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 confirm what’s available for the specified product when we quote.
What does an EI 60 rating mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Alfold need work, visits can be combined. You will have a fixed quote before work starts.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready

Advice
Compartment walls and floors in Alfold
At about 33 miles from central London, Alfold 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. 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. Either way, we install the specified product to its tested detail.
For a unit at a site such as The Old Brickworks Industrial Estate (2.8 miles east of Alfold), new power or data runs between office and warehouse can breach a compartment wall. In a building such as Church of St Nicholas, any service penetration through a fire-resisting wall should be sealed to the specified detail.
