How we handle fire stopping in Latimer
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. We work on linear gaps at wall heads, cable penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are fire-stopping items raised at inspection or handover and unsealed openings around new pipes and cables. Facilities teams, main contractors and managing agents in Latimer tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Latimer, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Issuing fire ratings or certificates for seals
- Fire doors, dampers or other fire safety equipment
- Large openings beyond what any sealant detail covers
Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly before you book.

Common questions from Latimer clients
Could you schedule work at a campus like Buckinghamshire New University for the vacation?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
What happens to BS 476 references for fire stopping in Latimer?
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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
Service penetrations in Latimer buildings
Central London is about 23 miles from Latimer. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. Several hotels sit less than 2 miles from Latimer. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
For a building at a site such as Boughton Business Park, 1.1 miles south-west of Latimer, a check of penetration seals after each fit-out is good practice. Older community buildings such as Church of St Mary Magdalene that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Latimer is about 2 miles east of Amersham, in Buckinghamshire. We cover commercial sites throughout Latimer, for single jobs and planned programmes alike. Across Buckinghamshire, 308 places are covered, including Latimer. London is covered too, around 23 miles from Latimer.

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.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Common problems we fix in Latimer
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it.
Typical triggers for a call:
- Builders’ foam or ordinary silicone in compartment walls
- Fire seals cut back for extra cables and never reinstated
- Fire-stopping items raised at inspection or handover
- Unsealed penetrations discovered above suspended ceilings
At a university such as Buckinghamshire New University, 3.9 miles west of Latimer, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Before you book anyone

- Do they follow the manufacturer’s priming guidance?
Work for main contractors and building owners
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.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Latimer can form part of a wider programme.
Why act early in Latimer
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. Older rural buildings around Latimer move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. If others near Latimer need work, visits can be combined. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Tell us what induction or permit system the site runs
- Tell staff and tenants when we’ll be in
- Point out parking and an unloading spot
