About our fire stopping in Farleigh Wallop
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal, not a rule of thumb. If you have seals that don’t match their tested detail and fire-stopping items raised at inspection or handover, we can put it right. Whoever orders the work in Farleigh Wallop, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
A job near Farleigh Wallop is normally planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. If others near Farleigh Wallop need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Have the specification and drawings to hand
- Let building users know which areas are affected
- Tell us your opening times and when work is allowed

Common questions from Farleigh Wallop clients
Can you work on a hospital site such as Basingstoke and North Hampshire Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What does the BS 476 change mean for fire-rated sealant in Farleigh Wallop?
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. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
What sets the cost
Before we quote, we look at:
- Removal of failed or old sealant
- Phasing around occupants
- Location, for remote and island sites
- The size and state of each joint
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What we need to price the job
Diagnosis starts before we arrive. Tell us:
- Photos of the joints, close up and from further back
- The site address and postcode
- The product your specification calls for
- Whether an asbestos survey exists
To get a fixed quote, give us a call on 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. Our quote form is another easy route.
Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Honest limits
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Plastic pipes whose detail calls for a collar or wrap
- Construction that lacks the fire resistance the seal relies on
- Fire doors, dampers or other fire safety equipment
Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly.
Joints and surfaces we work on
- Cable penetrations
- Pipe penetrations
- Linear gaps at wall heads
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
Why it’s worth doing now in Farleigh Wallop
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. For buildings around smaller places like Farleigh Wallop, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Fire stopping of openings and penetrations in England falls under Approved Document B.

We install whatever has been specified, to the product’s tested detail. At about 48 miles from central London, Farleigh Wallop is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

What we are called out for in Farleigh Wallop
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.
Things that usually lead to an enquiry:
- Fire seals cut back for extra cables and never reinstated
- Openings found when ceilings come down for a refit
- Service penetrations left open after M&E works
- Old intumescent sealant that has split away
Tenant changes at parks like Viables Business Park (to the north of Farleigh Wallop) bring new data and services, and openings through fire-resisting walls need the specified seal.
