About our fire stopping in Dunk's Green
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, give us a call on 01277 525 020 or email drawings and photos with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. Site teams most often ask us about damaged fire seals in risers and voids and unsealed openings around new pipes and cables, on linear gaps at wall heads, service gaps in risers and joints between fire-resisting walls and floors. A single leaking joint is often how a building in Dunk's Green first comes to us: we look at the rest while we’re there and tell you what we find.
For a smaller site near Dunk's Green, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

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 any bundle too large for sealant alone is flagged.
Metal pipes
Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.
What affects the price in Dunk's Green
These are the things that shape the price:
- Induction, permit and paperwork requirements
- Access and working height
- How much there is to seal
- The product specified
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

Related advice
General trades versus a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Why deal with it now?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down. Converted and older buildings near places like Dunk's Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Questions about Dunk's Green
Can you work at a site such as The Alders Industrial Estate, by Dunk's Green?
Yes. We cover Dunk's Green and the area around it, including industrial estates, business parks and retail parks such as The Alders Industrial Estate. To start, just call 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can you work on a hospital site such as Tonbridge Cottage Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do you certify or sign off fire stopping?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Can you fire stop behind the services contractors?
Yes, where there is a specification for those walls and floors. Openings left by new services are among the most common jobs we see and we close them with the specified product.
