Fire stopping near Puddledock
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How we handle fire stopping in Puddledock
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. Most enquiries involve expanding foam used as fire stopping and penetration schedules that need working through, on cable penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows. Facilities teams, main contractors and managing agents in Puddledock tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Smaller places such as Puddledock still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Reviewing a building’s overall fire safety
- Construction that lacks the fire resistance the seal relies on
- Designing or specifying fire stopping, which sits with the designer or fire engineer
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly before you book.
What we seal
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Linear gaps at wall heads
- Cable penetrations
- Joints between fire-resisting walls and floors
When to call us in Puddledock
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps. The tested detail for a linear joint states the width and movement it covers.
Any of the following is a good reason to get the joints checked over:
- Unsealed joints where partitions meet the slab
- Fire seals cut back for extra cables and never reinstated
- Openings left by services added after handover
- Fire stopping installed outside its tested range
Offices at parks like Pembroke Business Centre, 0.8 miles to the south-west of Puddledock, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.
Before you book anyone
- Will CSCS-carded applicators be on site?
- Are they CHAS accredited or on Constructionline?
- Their public liability cover
- Whether primer will be used where the manufacturer specifies it
Building owners, agents and FMs in Puddledock
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Puddledock need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out first.
- 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
- Confirm the product named in the specification
- Tell us your opening times and when work is allowed
- Tell staff and tenants when we will be in
Getting a fixed quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Where services cross fire walls in Puddledock
Puddledock is about 13 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. A 2-mile radius around Puddledock takes in several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
For an estates team at a campus like University of Greenwich (4.3 miles east of Puddledock), summer M&E works are usually followed by a round of penetration sealing. For a unit at a centre such as Dartford Heath Retail Park, 1.9 miles north-east of Puddledock, penetration seals are worth checking after each shop fit.
Puddledock is about 1 mile north of Swanley, in Kent. We cover commercial sites throughout Puddledock, whether it’s a single job or part of a planned programme. Our Kent coverage takes in 931 places. For work in that direction, see our London page, about 13 miles away.
Work on service penetrations is covered throughout DA2 and BR8, for business premises of every kind. We also cover Hextable (1 mile south-east), Stonehill Green (1 mile south-west), Joyden's Wood (1 mile north), Wilmington (1 mile north-east) and Swanley Village (1 mile south-east).

Your questions answered
Would you work within a site like West Hill Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
What does the BS 476 change mean for fire-rated sealant in Puddledock?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Can you work while the building is occupied?
In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
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.
Why it’s worth doing now in Puddledock
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. Around Puddledock, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
