Different surfaces, different methods
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, so we check before sealing.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork typically needs a different solution set by the designer, and we’ll say if that applies.
How we handle fire stopping in Ballingdon Bottom
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. We work on linear gaps at wall heads, cable penetrations and small duct penetrations where the tested detail allows, and what we’re called in for most is hidden openings found during inspections and expanding foam used as fire stopping. Facilities teams, main contractors and managing agents in Ballingdon Bottom tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For a smaller site near Ballingdon Bottom, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Don’t let anyone top up a fire seal with the wrong product
- Report damaged or disturbed seals as soon as they’re spotted
- Agree the fire-stopping specification before services go in
- Put resealing into every M&E and fit-out package
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, so check the product data first.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there instead of being left for someone else.
Penetration seals near Ballingdon Bottom
Central London is about 28 miles from Ballingdon Bottom. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail.
On a hospital site such as Hemel Hempstead Hospital (4.6 miles south of Ballingdon Bottom), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Holiday works at schools like Gaddesden Row JMI School often leave service openings to seal before pupils return.

When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Walls or floors that aren’t fire-resisting to begin with
- Fire risk assessments, a job for a competent assessor
- Approving the work on behalf of building control
If you’re not sure, just give us a call on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

FAQs: Ballingdon Bottom
Would you work within a site like Hemel Hempstead Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is Ballingdon Bottom too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
What does an EI 60 rating mean?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can you seal any opening with fire-rated sealant?
No. A sealant’s evidence covers set services, gaps and wall or floor types. Outside that, a different product is needed, specified by your designer.
How long does a job like this take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
On site: what to expect
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 we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Ballingdon Bottom are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- 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.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Tell us what induction or permit system the site runs
- Move anything stored against the joints
- Send your site hours and access windows

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. 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.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
