Common problems we fix in Shacklewell
A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position and has to be removed.
Typical triggers for a call:
- Seals disturbed by maintenance and left open
- Old intumescent sealant that has split away
- Unsealed openings around new pipes and cables
- Head-of-wall gaps with no fire seal
Workshops and IT rooms at colleges like New City College (0.7 miles north-east of Shacklewell) are re-serviced often, leaving penetrations to seal.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
- What level of public liability insurance do they hold?
- Will RAMS and insurance details be available?
About our fire stopping in Shacklewell
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance. We work on service gaps in risers, pipe penetrations and cable penetrations, and what we’re called in for most is snag lists that include open service penetrations and unsealed openings around new pipes and cables. Facilities teams, main contractors and managing agents in Shacklewell tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

- Gaps in walls that were never built as compartment walls
If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

- Cable penetrations

Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.
From enquiry to sign-off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking anything from one day to a planned run of visits, depending on the number of seals and the access. All of Greater London is in the ULEZ, and kerbside space in Shacklewell 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.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Send asbestos survey details if the building is pre-2000
- Agree which areas must stay open

Advice
Penetration seals near Shacklewell
With tenants changing and fit-outs following, London buildings see service routes altered again and again. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements. Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
At a university such as University of Wales Trinity Saint David London, 1.7 miles south-west of Shacklewell, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a unit at a site such as Bayford Street Industrial Centre, 1.1 miles south-east of Shacklewell, new power or data runs between office and warehouse can breach a compartment wall.

Maintenance after handover
After handover, these steps help:
- Ask which product is in place before decorating
- Include service cupboards in routine inspections
- Brief every trade that openings they make must be sealed
- Get seals inspected before ceilings and boxing close
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned.
