After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Put resealing into every M&E and fit-out package
- Leave fire sealant to cure fully before covering it
- Have penetrations checked while they can still be seen
- Keep general-purpose fillers away from compartment walls
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.
Fire stopping in Sudbury Hill
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. The enquiries we see most involve service penetrations left open after M&E works and seals disturbed by maintenance and left open, on cable penetrations, service gaps in risers and joints between fire-resisting walls and floors. Facilities teams, main contractors and managing agents in Sudbury Hill 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. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Other services in Sudbury Hill
Service penetrations in Sudbury Hill buildings
Sudbury Hill has three care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. The area within 2 miles of Sudbury Hill holds a good number of hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.
Campus buildings at universities such as Westminster University (to the north of Sudbury Hill) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. In a retail centre such as Westway Shopping Park, 1.2 miles south-west of Sudbury Hill, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. Colleges such as Katherine & King's College of London, 0.8 miles to the north-west of Sudbury Hill, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Sudbury Hill is about 1 mile south-west of Wembley, in Greater London. We send applicators to Sudbury Hill for service penetrations. 764 places across Greater London fall within our area, Sudbury Hill among them. Sites around London have their own page, roughly 10 miles from Sudbury Hill.
Commercial sites across HA0, UB6 and HA1 are covered. Buildings on Elms Lane, Harrow Road and Perrin Road are within our area for service penetrations. With the A4005 nearby, Sudbury Hill is straightforward for us to reach. We also cover Sudbury (1 mile west), North Wembley (1 mile east), Brondesbury Park (1 mile east), Harrow on the Hill (1 mile north-west) and Perivale (1 mile south) for service penetrations. Further afield, our area takes in London (10 miles east), City of Westminster (8 miles east), Marylebone (8 miles east), Kensington (6 miles south-east), St Pancras (9 miles east) and Shoreditch (11 miles east).
What’s near Sudbury Hill
Around Sudbury Hill, our work takes us to commercial buildings near Orley Farm School, Wembley High Technology College and Preston Park, among other places.

For a walk, there’s Castlebar Hill and Perivale Wood.
Why act early in Sudbury Hill
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Why appoint us
- Joints cleaned back to sound surfaces
- A Constructionline member, so easy to vet
- Commercial sealant work since 2005
- Workmanship guaranteed for 12 months
Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Fire doors, dampers or other fire safety equipment
- Large openings beyond what any sealant detail covers
- Issuing fire ratings or certificates for seals
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Joints and surfaces we work on
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal 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.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- 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.
Getting the site ready
- Let us know about inductions and permits
- Tell staff and tenants when we’ll be in
- For older buildings, check the asbestos register before work

Questions we’re asked in Sudbury Hill
Can you work around term dates at a campus such as Westminster University?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you seal around new services in a hotel near Sudbury Hill?
Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.
Can the building stay open while you work?
In most cases, yes. We phase the work so most of the building stays in use.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
How the job changes by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point against the detail’s limits, and any that don’t are flagged.
Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork usually needs a different solution set by the designer, and we’ll say if that applies.
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
