Fire stopping in St Paul's Cray, done properly
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. Those on your schedule are closed with the specified product. If you have seals that don’t match their tested detail and non-fire-rated filler around services, we can put it right, on pipe penetrations, service gaps in risers and linear gaps at wall heads alike. Facilities teams, main contractors and managing agents in St Paul's Cray tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Quoting for work in St Paul's Cray
Your fixed quote is built from the real scope. It allows for:
- Quantities, in metres or numbers
- Which sealant the job calls for
- Any access equipment needed
- Working within restricted access windows
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- A wide shot and a close-up of the area
- The site address and postcode
- Rough lengths or quantities, or drawings if you have them
- Any specification or named product
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or use the quote form.
What the job involves on each surface
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.
Do you need fire stopping in St Paul's Cray?
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
Site and facilities staff are often the first to spot these:
- Unsealed joints where partitions meet the slab
- Builders’ foam or ordinary silicone in compartment walls
- Seals disturbed by maintenance and left open
- Unsealed openings around new pipes and cables
Where a unit on an estate such as Brook Industrial Estate, which lies south-east of St Paul's Cray, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
What your quote should include
- Proof of insurance
- How the joint faces will be prepared and primed
- Can the work be phased to keep areas open?
- Will CSCS-carded applicators be on site?
How a job runs
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a job in St Paul's Cray, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site

Penetration seals near St Paul's Cray
St Paul's Cray has 10 care or nursing homes no more than 2 miles away. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Either way, we install the specified product to its tested detail.
Campus buildings at universities such as University of Greenwich Avery Hill Campus, 3.4 miles to the north of St Paul's Cray, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Hotels like TLK Apartments & Hotel (0.5 miles south-east of St Paul's Cray) are refurbished in phases, and each phase can open up compartment walls.

Site staff or a sealant specialist?
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, which is what makes a joint last.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
