How we handle fire stopping in Farnham
Facilities managers in Farnham 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. Where there isn’t one, the designer or fire engineer needs to set one first. If you are dealing with hidden openings found during inspections and fire stopping installed outside its tested range, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Farnham is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Towns the size of Farnham have plenty of buildings with compartment walls: schools, care homes, surgeries, offices and blocks of flats. New cabling or pipework through a fire-resisting wall leaves a gap that has to be made good with the specified product.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email the details over and we’ll arrange a return visit.

General trades versus a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
What we can’t put right
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Reviewing a building’s overall fire safety
- Gaps in walls that were never built as compartment walls
- Openings that need collars, wraps, batts or boards rather than sealant
If you’re not sure, just call 01277 525 020 or email the details over and we will give you a straight answer before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Cable penetrations
- Service gaps in risers
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Have penetrations checked while they can still be seen
- Don’t let anyone top up a fire seal with the wrong product
- File the specified details where the next contractor can find them
- Report damaged or disturbed seals as soon as they’re spotted
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
Commercial clients in Farnham
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Questions we are asked in Farnham
Do you work in occupied care homes around Farnham?
Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.
Do you take on work at healthcare sites like Farnham Community Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you guarantee your work?
Yes. Workmanship is guaranteed for 12 months on every job.
Do you hold third-party fire-stopping installer certification?
No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Where services cross fire walls in Farnham
In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. The 2 miles around Farnham include two care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product.
Tenant changes at centres like Farnham Retail Park, 0.8 miles north-east of Farnham, often mean new services through walls between units. On estates like Hookstile Trading Estate, under half a mile to the south-west of Farnham, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Hotels such as Hotel de Vie (to the south of Farnham) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Our process
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. In a town such as Farnham, most jobs are single buildings. Your photos, drawings or a site visit come first, followed by a fixed quote.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- 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.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Agree which areas must stay open
- Share the asbestos register for older buildings
- Make sure the joints can be reached
Ask for a quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email us with what you know.
