About our fire stopping in Norwood Green
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on pipe penetrations, service gaps in risers and cable penetrations, and the usual reasons a site gets in touch are unsealed penetrations discovered above suspended ceilings and penetration schedules that need working through. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Norwood Green, that means joint design, primers and backing rod as standard.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Why it’s worth doing now in Norwood Green
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Site staff or a sealant specialist?
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.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Questions we’re asked in Norwood Green
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. We allow for the ULEZ, which covers every borough
Can work at a site such as University of London fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Do the same rules apply to fire stopping in Scotland?
Our area runs from Greater London and the South East to every part of Scotland. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance.
How do I request a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
Do you approve fire stopping for building control?
No. Approval sits with the designer, principal designer or building control. We will confirm the product and detail installed, and you can tell us what other records you need at quote stage.
Do you have third-party installer accreditation for fire stopping?
No, and we won’t imply otherwise. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them. Where it isn’t required, we install the specified sealant to the maker’s details.
Can you tell us what fire stopping our building needs?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is installing what they specify, to the product’s tested detail.
Different surfaces, different methods
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 we tell you if the bundle exceeds what sealant covers.
Drylining partitions
Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness.
When it isn’t the sealant
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Fire risk assessments, a job for a competent assessor
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Issuing fire ratings or certificates for seals
If you’re not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer.

Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Record which product was used where
- Flag new cables with no seal around them
- Check with the data sheet before painting over fire sealant
- Check risers and ceiling voids after each round of works
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.
On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a job in Norwood Green, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned first.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
What we need from you
- Confirm the product named in the specification
- Tell us your opening times and when work is allowed
- Agree which areas must stay open

Advice
Fire-rated sealing for Norwood Green buildings
London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We seal to the specification and the product’s tested detail, working within the building’s permits. In England, Approved Document B covers fire stopping of openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail.
Theatres, wards and plant rooms at sites like Ealing Hospital, 1.2 miles north-east of Norwood Green, all have compartment walls crossed by services. Shop fits in centres such as Treaty Centre, 1.8 miles south of Norwood Green, can bring new services through fire-resisting walls between units, which then need the specified seal. Colleges such as Great Oaks College, 1.1 miles south-east of Norwood Green, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Norwood Green is about 1 mile south-east of Southall, in Greater London. Anywhere in UB2, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 764 places in Greater London. Our London page has more on work in that area (12 miles or so).
