Fire stopping for commercial buildings in Chesham Bois
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you’re dealing with hidden openings found during inspections and openings left by services added after handover, we can put it right. A single leaking joint is often how a building in Chesham Bois first comes to us: we look at the rest while we’re there and tell you what we find.
Converted and extended buildings around places like Chesham Bois can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Surface by surface
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range and we will tell you what the detail says instead.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers, and we work within it.
From enquiry to sign-off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Work in places the size of Chesham Bois is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out first.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Before we start on site
- Let building users know which areas are affected
- Explain the parking and delivery arrangements
- Flag any permit to work we’ll need

Common questions from Chesham Bois clients
Could you schedule work at a campus like Buckinghamshire New University for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Chesham Bois too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Is sealant suitable for all service openings?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. If an opening falls outside, it needs another solution.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
How do I request a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.
Do the same rules apply to fire stopping in Scotland?
Scotland sets its own building regulations, with Technical Handbooks, and England uses Approved Document B. Either way, we install the specified sealant to its tested detail.
Can you tell us what fire stopping our building needs?
No, we don’t design fire stopping. With the designer’s details in hand, we can price the sealant elements.
Common problems we fix in Chesham Bois
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.
Clients typically get in touch after noticing one or more of the following:
- Head-of-wall gaps with no fire seal
- Hidden openings found during inspections
- Snag lists that include open service penetrations
- Non-fire-rated filler around services
Where a unit on an estate such as Corinium Industrial Estate, 1.1 miles to the south-east of Chesham Bois, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
What to look for in a quote
- Whether primer will be used where the manufacturer specifies it
- Will CSCS-carded applicators be on site?
- What site paperwork they can supply
- Their approach to joint depth and backing
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Fire risk assessments, a job for a competent assessor
- Large openings beyond what any sealant detail covers
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Service gaps in risers
Why act early in Chesham Bois
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
