Fire stopping for commercial buildings in Stoke Newington
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, give us a call on 01277 525 020 or email a schedule or drawings with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. If you have seals that don’t match their tested detail and head-of-wall gaps with no fire seal, we can put it right, on joints between fire-resisting walls and floors, pipe penetrations and service gaps in risers alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Stoke Newington is the same: the right product in a properly prepared joint.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Being straight saves everyone time. New sealant won’t cure:
- Walls or floors that aren’t fire-resisting to begin with
- Writing the fire-stopping specification
- Signing off or certifying a building’s fire stopping
If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think.
Surfaces we seal
- Pipe penetrations
- Joints between fire-resisting walls and floors

What else we do in Stoke Newington
Your questions answered
Will you plan work around the academic year at somewhere like American University in London?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What does the BS 476 change mean for fire-rated sealant in Stoke Newington?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can the building stay open while you work?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Compartments and services around Stoke Newington
A good number of hotels sit less than 2 miles from Stoke Newington. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. 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.
Theatres, wards and plant rooms at sites like St Ann's Hospital (1.2 miles north of Stoke Newington) all have compartment walls crossed by services. For a unit at a site such as Frogmore Industrial Estate, 0.9 miles south-west of Stoke Newington, new power or data runs between office and warehouse can breach a compartment wall.

Do you need fire stopping in Stoke Newington?
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.
It’s worth sending us details if you spot any of the following:
- Head-of-wall gaps with no fire seal
- Builders’ foam or ordinary silicone in compartment walls
- Openings found when ceilings come down for a refit
- Openings left by services added after handover
Hotels such as The Rose Hotel, 0.7 miles to the south-east of Stoke Newington, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

General trades versus a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Different surfaces, different methods
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance along with any permits your site needs.
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest so we know it sits within the tested range, and any outside it are raised with you.
From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Point out any areas we must not close
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
