When something else is needed
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Gaps in walls that were never built as compartment walls
- Openings that need collars, wraps, batts or boards rather than sealant
- Issuing fire ratings or certificates for seals
If you’re not sure, just ring 01277 525 020 or email us and we will give you a straight answer before you book.
What we seal
- Cable penetrations
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
About our fire stopping in Chislehurst
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, call 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. Most enquiries involve unsealed openings around new pipes and cables and open linear gaps along the top of fire-resisting walls, on pipe penetrations, service gaps in risers and linear gaps at wall heads. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Chislehurst, that means joint design, primers and backing rod as standard.
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.
A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or use the quote form and we will come back to it.

Surface by surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables.
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance.
Why it’s worth doing now in Chislehurst
The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. In Chislehurst, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Quoting for work in Chislehurst
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Access and working height
- Induction, permit and paperwork requirements
- The size and state of each joint
- Which sealant the job calls for
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
What we need to price the job
A few photos plus some basic facts will normally do. It helps to include:
- Clear photographs of the problem areas
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them
- Whether an asbestos survey exists
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or send details through our quote form.
Fire stopping around Chislehurst: points for this area
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. There are a number of hotels within about 2 miles of Chislehurst. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
At a university such as University of Greenwich - Avery Hill, 2.3 miles north of Chislehurst, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Tenant changes at centres like The Mall (to the south-west of Chislehurst) often mean new services through walls between units. Wherever services are added at a hospital such as Queen Mary's Hospital (1.7 miles east of Chislehurst) the compartment line has to be made good with the specified product.

From enquiry to sign-off
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. In Chislehurst, 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.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out.
- 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 us your opening times and when work is allowed
- Flag any permit to work we will need
- Let building users know which areas are affected

Questions about Chislehurst
Do you take on jobs in Chislehurst where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Will you take on work at estates like Green Lane Business Park, close to Chislehurst?
Yes. Estates, retail parks and business parks around Chislehurst, Green Lane Business Park among them, are all within reach. A few photographs and the unit address let us price the work.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Are you members of a third-party fire-stopping installer scheme?
No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we’ll say so straight away rather than waste your time.
Do the same rules apply to fire stopping in Scotland?
Building standards in Scotland are separate from England’s, and England uses Approved Document B. Wherever the site is, our work follows the specification and the tested detail.
