Fire stopping in Boyn Hill
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on cable penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows, and what we’re called in for most is penetration schedules that need working through and open linear gaps along the top of fire-resisting walls. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Boyn Hill, that means joint design, primers and backing rod as standard.
Around smaller places like Boyn Hill, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Plastic pipes whose detail calls for a collar or wrap
- Signing off or certifying a building’s fire stopping
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we will tell you honestly.
Surfaces we seal

Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
How the job changes by surface
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance.
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables and we work within those limits.
Service penetrations in Boyn Hill buildings
For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. At about 28 miles from central London, Boyn Hill is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
Hospital estates such as St Mark's Hospital (to the north of Boyn Hill) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For a building at a site such as Vanwall Business Park, less than half a mile to the north-west of Boyn Hill, a check of penetration seals after each fit-out is good practice. For a unit at a centre such as Cliveden View Shopping Centre, which lies north of Boyn Hill, penetration seals are worth checking after each shop fit.

Questions about Boyn Hill
Can you work in a care home near Boyn Hill with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
Does your area include sites such as Vanwall Business Park, near Boyn Hill?
Yes. Our area takes in Boyn Hill and its surroundings, with estates and business parks such as Vanwall Business Park included. Photos and a short description are enough for a first look.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
Can you tell us what fire stopping our building needs?
No. The specification comes from your designer, fire engineer or building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
Do you approve fire stopping for building control?
No. Sign-off belongs to the designer or building control, not the installer. We will confirm the product and detail installed, and you can tell us what other records you need at quote stage.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Why it’s worth doing now in Boyn Hill
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
