Signs you need fire stopping in Finsbury Park
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
It’s worth sending us details if you spot any of the following:
- Fire stopping installed outside its tested range
- Openings left by services added after handover
- Fire seals cut back for extra cables and never reinstated
- Expanding foam used as fire stopping
For a hotel such as Lanark Hotel (under half a mile south-east of Finsbury Park), penetration seals are worth checking after any refit or services upgrade.
What your quote should include
- Their plan for phasing and protecting the area
- Are they CHAS accredited or on Constructionline?
- What level of public liability insurance do they hold?
- Is the sealant right for the movement and the substrate?
Fire stopping in Finsbury Park
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Finsbury Park and nearby. We work on cable penetrations, pipe penetrations and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are seals disturbed by maintenance and left open and expanding foam used as fire stopping. One point of contact handles commercial sealant work in Finsbury Park from the first photos to the final walk-round, whether it’s one building or several.
In a London area such as Finsbury Park, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. In Finsbury Park, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we confirm the product and tested details named in the specification.
- 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
- Clear stock, furniture or equipment away from the joints
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits

Advice
What sets the cost
We price every job individually. The things that drive the figure:
- Phasing around occupants
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
- Any access equipment needed
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- What the building is and how it’s used
- When you need the work done
- The product your specification calls for
- Where the site is, with the postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Aftercare for building managers
Problems stay small when the joints are checked regularly. In particular:
- Agree the fire-stopping specification before services go in
- Put resealing into every M&E and fit-out package
- Flag new cables with no seal around them
- Get seals inspected before ceilings and boxing close
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.
Leave it or put it right?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is typically a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. In Finsbury Park, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Compartment walls and floors in Finsbury Park
Three care or nursing homes sit less than 2 miles from Finsbury Park. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. There are plenty of hotels within about 2 miles of Finsbury Park. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
For an estates team at a campus like American University in London, 0.7 miles to the south-west of Finsbury Park, summer M&E works are usually followed by a round of penetration sealing. Hospital estates such as St Ann's Hospital (1 mile north-east of Finsbury Park) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
