Our process
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- 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.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Have the specification and drawings to hand
- Agree which areas must stay open
- Send asbestos survey details if the building is pre-2000

Advice
How we handle fire stopping in Hampstead Garden Suburb
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. Those on your schedule are closed with the specified product. If you have hidden openings found during inspections and expanding foam used as fire stopping, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Hampstead Garden Suburb, that means joint design, primers and backing rod as standard.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Signs you need fire stopping in Hampstead Garden Suburb
Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe and the opening isn’t always resealed.
Typical triggers for a call:
- Snag lists that include open service penetrations
- Old intumescent sealant that has split away
- Seals disturbed by maintenance and left open
- Seals that don’t match their tested detail
Refits at places like Brent Cross Shopping Park (1.9 miles south-west of Hampstead Garden Suburb) often reroute services through walls between units.
Questions to ask before you book
- The terms of the workmanship guarantee
- Who will actually carry out the work
- The named product and why it was chosen
- Do they follow the manufacturer’s priming guidance?
Why it’s worth doing now in Hampstead Garden Suburb
Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Hampstead Garden Suburb: questions and answers
How does the move away from BS 476 affect penetration seals in Hampstead Garden Suburb?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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 occupied care homes around Hampstead Garden Suburb?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact.
How much does the work cost?
There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
When to bring in a specialist
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. Getting these wrong usually costs more in the end than doing them right.
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.
Penetration seals near Hampstead Garden Suburb
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail. Hampstead Garden Suburb has six care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.
