Service penetrations in Stonehill Green buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. A 2-mile radius around Stonehill Green takes in a number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Residences at universities like University of Greenwich Avery Hill Campus (to the north-west of Stonehill Green) have compartment walls that must be resealed whenever services change. Workshops and IT rooms at colleges like North Kent College (to the north-east of Stonehill Green) are re-serviced often, leaving penetrations to seal.

Fire stopping in Stonehill Green, done properly
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. 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 small duct penetrations where the tested detail allows, service gaps in risers and pipe penetrations, and the failures we’re asked to look at most are openings left by services added after handover and unsealed joints where partitions meet the slab. Whether you call it commercial sealant work, mastic application or joint sealing, in Stonehill Green it comes down to the same thing: the right product in a properly prepared joint.
Smaller places such as Stonehill Green still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Cost factors for service penetrations
What shapes the price:
- Access and working height
- Site requirements such as inductions and permits
- Quantities, in metres or numbers
- The product specified
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
Sending details for a quote
A good diagnosis starts with the right details. Let us know:
- A wide shot and a close-up of the area
- The asbestos register, for older buildings
- When you need the work done
- Access details, including height
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or email us.
Why deal with it now?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. One visit to deal with every failing joint makes more sense than several trips to a place like Stonehill Green. Send photographs of each area and we will quote for the lot.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
Why us?
- Failed material removed, not covered up
- Work carried out by CSCS-carded applicators
- A fixed quote before work starts
- Health and safety: CHAS accredited
Building owners, agents and FMs in Stonehill Green
Building owners and managing agents use us on everything from one building to a spread of sites around Stonehill Green. One quote can cover more than one site, which keeps the paperwork simple.
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. Jobs in and around smaller places like Stonehill Green are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We start with your penetration schedule, drawings or specification.
- 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.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Send your site hours and access windows
- Clear stock, furniture or equipment away from the joints
- Point out parking and an unloading spot
Quotes
Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email drawings and photos.
Advice
Stonehill Green: questions and answers
Is Stonehill Green too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Stonehill Green?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s 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 we raise anything unclear before work begins.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Ask the designer to confirm details early on refits
- Keep general-purpose fillers away from compartment walls
- Brief every trade that openings they make must be sealed
- Arrange inspection before areas are covered up
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
Common problems we fix in Stonehill Green
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Clients typically get in touch after noticing something like this:
- Fire seals cut back for extra cables and never reinstated
- Service penetrations left open after M&E works
- Non-fire-rated filler around services
- Fire stopping installed outside its tested range
Large healthcare estates like Queen Mary's Hospital (to the west of Stonehill Green) change their services often, so penetration seals are worth checking after M&E work.
