Sealant work in Fernham for main contractors, managing agents and facilities managers: fire-rated and intumescent sealing of service penetrations and linear gaps, with a fixed quote first.

Fire stopping in Fernham
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Openings that need collars, wraps, batts or boards rather than sealant
- Signing off or certifying a building’s fire stopping
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If you’re not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer.
Where we work in Fernham

Fire stopping for commercial buildings in Fernham
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and what we’re called in for most is head-of-wall gaps with no fire seal and fire stopping installed outside its tested range. A specialist sealant contractor works differently from a general builder: on jobs in Fernham, preparation and product choice get the time they need.
Barn and farm-building conversions near places like Fernham 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.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Keeping the joints sound
After handover, a little attention goes a long way:
- Flag new cables with no seal around them
- Brief every trade that openings they make must be sealed
- Settle who seals which penetrations at the start of a project
- Get seals inspected before ceilings and boxing close
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small.
Commercial clients in Fernham
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.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.
How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Joint width, depth and condition
- Working within restricted access windows
- Access and working height
- The product specified
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Before you send an enquiry
However big the job, these details speed things up:
- Your programme or deadline
- The product your specification calls for
- The postcode of the building
- Photos of the joints, close up and from further back
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
What else we do in Fernham
Questions we are asked in Fernham
Is a hospital such as Faringdon Day Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Is Fernham too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Will you write the fire-stopping specification?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Compartment walls and floors in Fernham
Fernham is about 64 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
In a building such as Church of St John, any service penetration through a fire-resisting wall should be sealed to the specified detail. Large healthcare estates like Faringdon Day Hospital (2.2 miles north of Fernham) change their services often, so penetration seals are worth checking after M&E work.

When to call us in Fernham
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and the wrong product can split as a result. Linear joint details set a width range and movement capability, and the seal has to sit within them.
These are often picked up first by site or facilities staff:
- Seals disturbed by maintenance and left open
- Unsealed penetrations discovered above suspended ceilings
- Improvised or mixed-product fire seals
- Head-of-wall gaps with no fire seal
Offices at parks like Faringdon Business Park, 1.4 miles to the north-west of Fernham, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- How they handle RAMS and site documents
- Will CSCS-carded applicators be on site?
- Will failed sealant be removed rather than covered?
Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Fernham, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- 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.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Make sure the joints can be reached
- Let building users know which areas are affected
- Explain the parking and delivery arrangements
