About our fire stopping in Crooked Billet
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. Most enquiries involve fire sealant pulled out of the opening and unsealed penetrations discovered above suspended ceilings, across cable penetrations, joints between fire-resisting walls and floors and service gaps in risers. One point of contact handles commercial sealant work in Crooked Billet from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In a London area such as Crooked Billet, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Compartments and services around Crooked Billet
Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. We seal to the specification and the product’s tested detail, working within the building’s permits. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
For an estates team at a campus like Kingston University Roehampton Vale Campus (1.5 miles north-west of Crooked Billet), summer M&E works are typically followed by a round of penetration sealing. Workshops and IT rooms at colleges like Wimbledon College of Arts, 0.9 miles south-east of Crooked Billet, are re-serviced often, leaving penetrations to seal.

How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- 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.
Getting the site ready
- Send any specification or drawings in advance
- Tell us your opening times and when work is allowed
- Let building users know which areas are affected
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Maintenance after handover
To get the most from the new sealant:
- Report damaged or disturbed seals as soon as they’re spotted
- Leave fire sealant to cure fully before covering it
- Settle who seals which penetrations at the start of a project
- Have penetrations checked while they can still be seen
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
Building owners, agents and FMs in Crooked Billet
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

FAQs: Crooked Billet
What does the BS 476 change mean for fire-rated sealant in Crooked Billet?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Do you work in Crooked Billet?
Yes. Crooked Billet falls within our area, and the simplest way to start is to call the office on 01277 525 020 or email us.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Surface by surface
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork typically needs a different solution set by the designer, and we’ll say if that applies.
Signs you need fire stopping in Crooked Billet
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in and later need putting right.
If one of these sounds familiar, it’s time for a closer look:
- Builders’ foam or ordinary silicone in compartment walls
- Service penetrations left open after M&E works
- Snag lists that include open service penetrations
- Fire-rated sealant that has cracked or shrunk back
For a hospital such as New Victoria Hospital, 1.2 miles west of Crooked Billet, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.
Questions to ask before you book
- What level of public liability insurance do they hold?
- Health and safety accreditation such as CHAS
- Their approach to joint depth and backing
- Is the sealant right for the movement and the substrate?
