Fire stopping in Sundridge, 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 rather than guesswork. We work on pipe penetrations, cable penetrations and service gaps in risers, and the usual reasons a site gets in touch are open linear gaps along the top of fire-resisting walls and fire seals cut back for extra cables and never reinstated. Facilities teams, main contractors and managing agents in Sundridge 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.
Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or send photos by email and we’ll come back to it.

Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Flag new cables with no seal around them
- Arrange inspection before areas are covered up
- Foam or ordinary sealant is never a fire-seal repair
- Ask which product is in place before decorating
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts.
Cost factors for service penetrations
These are the things that shape the price:
- The size and state of each joint
- How accessible the joints are
- The site’s rules and procedures
- How much existing material needs removing
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote when you’re ready.
Details that help us quote
To price the job accurately, we need a clear picture of the site. Send us:
- The postcode of the building
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older
- How the joints are reached, and at what height
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or send photos by email if you’d rather talk the job through.
Fire stopping in Sundridge: the local picture
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. There are a number of hotels within about 2 miles of Sundridge. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.
For an estates team at a campus like University of Greenwich - Avery Hill, 3 miles north-east of Sundridge, summer M&E works are normally followed by a round of penetration sealing. At a healthcare site like Sloane Hospital, 1.4 miles to the south-west of Sundridge, new services through compartment walls are a constant, and each needs the specified seal.

Different surfaces, different methods
Drylining partitions
Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.
Our process
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking a single visit for a short list of penetrations, or a phased programme for a whole building. In Sundridge, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Before we start on site
- Tell staff and tenants when we’ll be in
- Agree which areas must stay open
- For older buildings, check the asbestos register before work

Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
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, which is what makes a joint last.
Common problems we fix in Sundridge
Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped and the opening isn’t always resealed.
Things that normally lead to an enquiry:
- Hidden openings found during inspections
- Fire-stopping items raised at inspection or handover
- Open linear gaps along the top of fire-resisting walls
- Service penetrations left open after M&E works
Office fit-outs on sites such as Chartwell Business Centre (1.4 miles south of Sundridge) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.
