Fire stopping for Knaphill sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Fire stopping in Knaphill
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations, and the failures we are asked to look at most are unsealed penetrations discovered above suspended ceilings and penetration schedules that need working through. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Knaphill, preparation and product choice get the time they need.
In places the size of Knaphill, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Different surfaces, different methods
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement.
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.
Cost factors for service penetrations
Your fixed quote is built from the real scope. It takes account of:
- The size and state of each joint
- The total length or number of joints
- The product specified
- Travel to remote or island sites
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- Rough lengths or quantities, or drawings if you have them
- Clear photographs of the problem areas
- Whether an asbestos survey exists
- Any dates the work must fit around
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
FAQs: Knaphill
Is Knaphill off your patch?
Not at all. Knaphill is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Could you schedule work at a campus like University of Surrey for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Is the BS 476 change in 2029 relevant to fire stopping?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, though transitional rules apply. Scotland follows its own Technical Handbook.
Can you reseal penetrations after our M&E works?
Yes. Send the schedule or marked-up drawings and the specified product details for a fixed quote. Work can run area by area behind the M&E trades so areas aren’t left open.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Fire stopping around Knaphill: what changes locally
Several hotels sit less than 2 miles from Knaphill. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Central London is about 26 miles from Knaphill. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
Hotels like Gorse Hill Hotel, 1.5 miles to the south-east of Knaphill, are refurbished in phases, and each phase can open up compartment walls. In a building such as St Hugh of Lincoln's Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. Campus buildings at universities such as University of Surrey (5 miles south of Knaphill) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Why deal with it now?
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Our process
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. If neighbouring businesses or buildings around Knaphill need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- The specification and schedule come first, so we know which details apply.
- 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.
What we need from you
- Flag any permit to work we will need
- For older buildings, check the asbestos register before work
- Make sure the joints can be reached
