Fire stopping for Bopeep sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Fire stopping in Bopeep, done properly
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, 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 cable penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads, and the failures we’re asked to look at most are fire-rated sealant that has cracked or shrunk back and unsealed openings around new pipes and cables. Facilities teams, main contractors and managing agents in Bopeep tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we’ll confirm with the quote.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What the job involves on each surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter.
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do and we’ll tell you what the detail says instead.
What affects the price in Bopeep
Before we quote, we look at:
- How accessible the joints are
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
- The size and state of each joint
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- Your programme or deadline
- Drawings or a marked-up plan, if available
- Anything awkward about access or site hours
- Whether an asbestos survey exists
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or send photos by email with what you know.
What happens if it’s left?
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. Failed sealant in a building in Bopeep can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
Pricing service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Your questions answered
Do you take on jobs in Bopeep where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Do you cover business parks and estates near Bopeep, such as North Downs Business Park?
Yes. Our area takes in Bopeep and its surroundings, with estates and business parks such as North Downs Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Is fire stopping in Scotland covered by different guidance?
Building standards in Scotland are separate from England’s, while England relies on Approved Document B. Either way, we install the specified sealant to its tested detail.
Do you guarantee your work?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Do you approve fire stopping for building control?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
After the work
For the best life from the joints:
- Treat an open penetration as a priority repair
- Ask the designer to confirm details early on refits
- Don’t let anyone top up a fire seal with the wrong product
- Include service cupboards in routine inspections
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

What else we do in Bopeep
When to call us in Bopeep
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.
Any of the following is a good reason to get the joints checked over:
- Hidden openings found during inspections
- Damaged fire seals in risers and voids
- Penetration schedules that need working through
- Fire-rated sealant that has cracked or shrunk back
Office fit-outs on sites such as North Downs Business Park (to the south of Bopeep) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.
Questions to ask before you book
- Their approach to joint depth and backing
- How they handle RAMS and site documents
- Can the work be phased to keep areas open?
- Do they follow the manufacturer’s priming guidance?
From enquiry to sign-off
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on 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. All of Greater London is in the ULEZ, and kerbside space in Bopeep can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- For older buildings, check the asbestos register before work
- Let building users know which areas are affected
- Tell us which areas need to stay in use
