Fire stopping for commercial buildings in Mottingham
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. We work on joints between fire-resisting walls and floors, pipe penetrations and cable penetrations, and what we are called in for most is seals disturbed by maintenance and left open and improvised or mixed-product fire seals. Facilities teams, main contractors and managing agents in Mottingham tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Service penetrations in Mottingham buildings
For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
Campus buildings at universities such as University of Greenwich - Avery Hill, 2 miles to the north-east of Mottingham, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. For a unit at a centre such as The Mall (2.3 miles south of Mottingham), penetration seals are worth checking after each shop fit. Office fit-outs on sites such as Green Lane Business Park, 1.1 miles east of Mottingham, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Common questions from Mottingham clients
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method.
Will you plan work around the academic year at somewhere like University of Greenwich - Avery Hill?
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.
Is sealant suitable for all service openings?
No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we flag those rather than improvise.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.
Can weather delay the job?
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. Internal work is far less affected.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Maintenance after handover
After handover, a little attention goes a long way:
- Look above ceilings when tiles are lifted for other jobs
- Don’t let anyone top up a fire seal with the wrong product
- Treat an open penetration as a priority repair
- Have penetrations checked while they can still be seen
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, and the data sheet says which.
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, and installation follows the programme.
How the quote is worked out
These are the things that shape the price:
- Location, for remote and island sites
- Removal of failed or old sealant
- The site’s rules and procedures
- Which sealant the job calls for
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
What we need to price the job
A good diagnosis starts with the right details. Tell us:
- Specification clauses that apply
- Asbestos survey details if the building is older
- Access details, including height
- The type of building and who uses it
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or use the quote form with what you know.
What the job involves on each surface
Small ducts
We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.
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 any bundle too large for sealant alone is flagged.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Gaps in walls that were never built as compartment walls
- Openings that need collars, wraps, batts or boards rather than sealant
- Signing off or certifying a building’s fire stopping
If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think before you book.
What we seal
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. Planning a London job such as one in Mottingham starts with access. Send the building rules and access times with your enquiry.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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.
What we need from you
- Let us know about inductions and permits
- Move anything stored against the joints
- Arrange parking or a loading space
