Fire stopping in Foxholes, done properly
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. Site teams most often ask us about expanding foam used as fire stopping and improvised or mixed-product fire seals, on small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads. Looking for mastic applicators who cover Foxholes? We’ve been sealing commercial buildings since 2005.
Converted and extended buildings around places like Foxholes can mix old and new construction, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Leave it or put it right?
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Questions about Foxholes
Will you plan work around the academic year at somewhere like Hertford College: Ware Campus?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Foxholes too small for you to travel to?
No. Places such as Foxholes are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you approve fire stopping for building control?
No. Sign-off belongs to the designer or building control, not the installer. We will confirm the product and detail installed.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months.
Are you members of a third-party fire-stopping installer scheme?
No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so check your contract first. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Owners, agents and contractors
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Foxholes can sit alongside others in a wider programme.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Foxholes. One quote can cover more than one site, so there’s one set of paperwork to deal with.
What we’re called out for in Foxholes
Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.
Things that usually lead to an enquiry:
- Old intumescent sealant that has split away
- Improvised or mixed-product fire seals
- Builders’ foam or ordinary silicone in compartment walls
- Seals disturbed by maintenance and left open
Older community buildings such as Church of the Holy Trinity that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

On site: what to expect
Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Work in places the size of Foxholes is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- 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.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
- Confirm the product named in the specification
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What the job involves on each surface
Metal pipes
Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance along with any permits your site needs.
