Fire stopping in Farnborough
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you have fire-rated sealant that has cracked or shrunk back and openings found when ceilings come down for a refit, we can help, whatever the surface. A single leaking joint is often how a building in Farnborough first comes to us: we look at the rest while we’re there and tell you what we find.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you’ll hear it from us.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Keeping the joints sound
To get the most from the new sealant:
- Treat an open penetration as a priority repair
- Put resealing into every M&E and fit-out package
- Check with the data sheet before painting over fire sealant
- Settle who seals which penetrations at the start of a project
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
FAQs: Farnborough
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Can you take on a job at a hospital such as Princess Royal University Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Is sealant suitable for all service openings?
No. Sealant is the right product only where the tested detail says so. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we’ll tell you when that applies.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you tell us what fire stopping our building needs?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements, and tell you if a detail needs another product.
Why deal with it now?
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Writing the fire-stopping specification
- Openings that need collars, wraps, batts or boards rather than sealant
- Signing off or certifying a building’s fire stopping
If in doubt, ring 01277 525 020 or email a schedule or drawings and we’ll say what we think.
Surfaces we seal
- Pipe penetrations
- Cable penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
Do you need fire stopping in Farnborough?
Openings in fire-resisting walls usually appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Common reasons buildings call us in:
- Penetration schedules that need working through
- Openings found when ceilings come down for a refit
- Damaged fire seals in risers and voids
- Old intumescent sealant that has split away
Theatres, wards and plant rooms at sites like Princess Royal University Hospital (to the north-west of Farnborough) all have compartment walls crossed by services.

What else we do in Farnborough
Different surfaces, different methods
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones normally call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
From enquiry to sign-off
When we get to site, 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 anything is cut or cleaned, and the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. In Farnborough, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- 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.
Getting the site ready
- Send your site hours and access windows
- Send any specification or drawings in advance
- Clear stock, furniture or equipment away from the joints

Where services cross fire walls in Farnborough
There are four care or nursing homes within about 2 miles of Farnborough. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. 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. We install whatever has been specified, to the product’s tested detail.
Schools such as Farnborough Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. For a building such as Church of St Giles the Abbot, new heating or data runs are the usual reason penetrations need sealing.
