Fire stopping in Bray Wick
Facilities managers in Bray Wick often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you’re dealing with openings found when ceilings come down for a refit and service penetrations left open after M&E works, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Bray Wick it comes down to the same thing: the right product in a properly prepared joint.
Barn and farm-building conversions near places like Bray Wick often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Questions we’re asked in Bray Wick
Will you take on work at estates like Priors Way Industrial Estate, close to Bray Wick?
Yes, sites like Priors Way Industrial Estate are within our area, along with the rest of Bray Wick. Send details of the unit and the work through our quote form for a quick quote.
Is a smaller place like Bray Wick outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Are you members of a third-party fire-stopping installer scheme?
No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t. Where it isn’t required, we install the specified sealant to the maker’s details.
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Walls or floors that aren’t fire-resisting to begin with
- Reviewing a building’s overall fire safety
- Openings that need collars, wraps, batts or boards rather than sealant
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.

From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. For work around Bray Wick, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- 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.
Getting the site ready
- Warn occupants and staff about the work
- Tell us what induction or permit system the site runs
- Send your site hours and access windows

Leave it or put it right?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. One visit to deal with every failing joint makes more sense than several trips to a place like Bray Wick. Photos of every joint help us quote for the whole job.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote when you are ready.

Signs you need fire stopping in Bray Wick
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in and later need putting right.
Things that normally lead to an enquiry:
- Seals disturbed by maintenance and left open
- Openings left by services added after handover
- Unsealed joints where partitions meet the slab
- Fire-rated sealant that has cracked or shrunk back
For a hotel such as Chauntry House Hotel, 0.7 miles north-east of Bray Wick, penetration seals are worth checking after any refit or services upgrade.
What your quote should include
- The named product and why it was chosen
- Will failed sealant be removed rather than covered?
- How they handle RAMS and site documents
- How long is the guarantee, and what does it include?
Service penetrations in Bray Wick buildings
The area within 2 miles of Bray Wick holds plenty of hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. Approved Document B is the English guidance that covers fire stopping around 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. Our part stays the same: the specified product, installed to its tested detail.
For a hospital such as St Mark's Hospital, which lies north-west of Bray Wick, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. For a unit at a site such as Priors Way Industrial Estate, under half a mile west of Bray Wick, new power or data runs between office and warehouse can breach a compartment wall.
