Fire stopping for businesses in Gravesend
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
From enquiry to sign-off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Gravesend are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Move anything stored against the joints
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed

Advice
Fire stopping in Gravesend, done properly
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail. Most enquiries involve head-of-wall gaps with no fire seal and fire-rated sealant that has cracked or shrunk back, on joints between fire-resisting walls and floors, cable penetrations and linear gaps at wall heads. A single leaking joint is often how a building in Gravesend first comes to us: we look at the rest while we are there and tell you what we find.
A job near Gravesend is usually planned around one visit, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Leave it or put it right?
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. Older rural buildings around Gravesend move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Maintenance after handover
Regular inspection catches problems early. In particular:
- Put resealing into every M&E and fit-out package
- Treat an open penetration as a priority repair
- Keep general-purpose fillers away from compartment walls
- Include service cupboards in routine inspections
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way, or a new specification from the designer.
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 the work runs in step with the M&E.
Compartments and services around Gravesend
In England, Approved Document B covers fire stopping of openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Central London is about 29 miles from Gravesend. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.
Wherever services are added at a hospital such as Herts and Essex Hospital (to the south-east of Gravesend) the compartment line has to be made good with the specified product. Schools such as Albury Church of England Voluntary Aided Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

When to call us in Gravesend
Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.
Clients normally get in touch after noticing something like this:
- Open linear gaps along the top of fire-resisting walls
- Fire-stopping items raised at inspection or handover
- Service penetrations left open after M&E works
- Damaged fire seals in risers and voids
Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Questions to ask before you book
- Can the work be phased to keep areas open?
- How long is the guarantee, and what does it include?

Your questions answered
How does the move away from BS 476 affect penetration seals in Gravesend?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Is Gravesend off your patch?
No. Places such as Gravesend are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
What do you charge?
There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we’ll price the work to it.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
