Fire stopping near Arnos Grove
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What the job involves on each surface
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers, and we work within it.
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits, and any that don’t are flagged.
About our fire stopping in Arnos Grove
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. The enquiries we see most involve hidden openings found during inspections and expanding foam used as fire stopping, on service gaps in risers, pipe penetrations and cable penetrations. A single leaking joint is often how a building in Arnos Grove first comes to us: we look at the rest while we are there and tell you what we find.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you’ll hear it from us.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Fire stopping around Arnos Grove: how the place shapes the job
There are a good number of hotels within about 2 miles of Arnos Grove. 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. With tenants changing and fit-outs following, London buildings see service routes altered again and again. We seal to the specification and the product’s tested detail, working within the building’s permits.
At a college such as Oak Hill College, which lies north-west of Arnos Grove, checking penetration seals after summer M&E works is good practice. Large healthcare estates like Priory Hospital, 1.2 miles to the north of Arnos Grove, change their services often, so penetration seals are worth checking after M&E work. Hotels such as Southgate Hotel London, 1.1 miles to the north of Arnos Grove, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
Arnos Grove is about 3 miles north-east of Finchley, in Greater London. Anywhere in N11, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Greater London coverage takes in 764 places, large and small. For work in that direction, see our London page.
Postcode districts covered here: N11, N14 and N13. Streets here include Oak Lane, High Road and York Road, and sites on any of them can send details for a fixed quote. Main routes into Arnos Grove include the A109 and A1004, which helps when planning parking and deliveries for the job.

Further afield, our area takes in London (8 miles south), City of Westminster (7 miles south), Marylebone (7 miles south), Kensington (9 miles south), St Pancras (6 miles south) and Shoreditch (7 miles south).
Around Arnos Grove
Around Arnos Grove, our work takes us to commercial buildings near The Ranelagh pub, Broomfield School and Broomfield Park and the streets around them. The closest station to Arnos Grove is New Southgate station, roughly 0.6 miles west of the centre. Nearby you will also find Broomfield House Museum (0.5 miles east) and The Mall Wood Green (1.7 miles south-east). The countryside around Arnos Grove includes Highgate Hill and Darland's Lake.
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Working within restricted access windows
- Site requirements such as inductions and permits
- Travel to remote or island sites
- The total length or number of joints
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- The postcode of the building
- Clear photographs of the problem areas
- The type of building and who uses it
- Rough lengths or quantities, or drawings if you have them
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
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, so it makes sense to get it right first time. Getting scaffold, permits or access booked in Arnos Grove takes effort, so it makes sense to deal with every failing joint while access is in place.

When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Issuing fire ratings or certificates for seals
- Openings that need collars, wraps, batts or boards rather than sealant
- Fire risk assessments, a job for a competent assessor

Joints and surfaces we work on

Questions about Arnos Grove
Can you seal penetrations in a hotel in Arnos Grove after a refit?
Yes, where the specification calls for fire-rated sealant. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Will you work in a care home in Arnos Grove without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you cover Arnos Grove?
Yes. Arnos Grove falls within our area, and you can call the office on 01277 525 020 or email drawings and photos to get started.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
What will the job cost?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.

What else we do in Arnos Grove
General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
How a job runs
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. All of Greater London is in the ULEZ, and kerbside space in Arnos Grove can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We read the specification, drawings or penetration schedule you send.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Have the specification and drawings to hand
- Warn occupants and staff about the work
- Tell us what induction or permit system the site runs
