Fire stopping for commercial buildings in Speed Gate
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Site teams most often ask us about head-of-wall gaps with no fire seal and snag lists that include open service penetrations, across cable penetrations, service gaps in risers and linear gaps at wall heads. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Speed Gate is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A job near Speed Gate is typically planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Leave fire sealant to cure fully before covering it
- Include service cupboards in routine inspections
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Get seals inspected before ceilings and boxing close
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.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.

What else we do in Speed Gate
Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Speed Gate, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- 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 so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Tell us which areas need to stay in use
- Warn occupants and staff about the work
- Send asbestos survey details if the building is pre-2000

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Advice
Surface by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
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.
What happens if it’s left?
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these, and the other benefits follow. For buildings around smaller places like Speed Gate, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Walls or floors that aren’t fire-resisting to begin with
- Large openings beyond what any sealant detail covers
- Signing off or certifying a building’s fire stopping

Penetration seals near Speed Gate
Fire stopping of openings and penetrations in England falls under Approved Document B. 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. The area within 2 miles of Speed Gate holds a number of hotels. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.
For a hospital such as Darent Valley Hospital (4.5 miles north of Speed Gate), penetration sealing is normally phased ward by ward, with infection-control rules agreed first. Industrial units on estates such as Heaver Farm Trading Estate, 1.3 miles south-east of Speed Gate, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. Hotels such as Brands Hatch Hotel (0.6 miles south of Speed Gate) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Your questions answered
How does the move away from BS 476 affect penetration seals in Speed Gate?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you work around term dates at a campus such as University of Greenwich?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months.
How much does the work cost?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
What hours do you work?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
How do I request a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
General trades versus a specialist
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
