About our fire stopping in Mursley
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, and they are easy to forget. Those on your schedule are closed with the specified product. If you have head-of-wall gaps with no fire seal and expanding foam used as fire stopping, we can put it right. Whoever orders the work in Mursley, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For a smaller site near Mursley, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Penetration seals near Mursley
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. At about 44 miles from central London, Mursley is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
For a hospital such as Bletchley Community Hospital, which lies north-east of Mursley, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. For a unit at a site such as Station Road Industrial Estate, 2.8 miles west of Mursley, new power or data runs between office and warehouse can breach a compartment wall.
Mursley is about 4 miles south-west of Bletchley, in Buckinghamshire. Commercial clients in Mursley use us for work on service penetrations, as part of our coverage of Buckinghamshire. Our Buckinghamshire coverage takes in 308 places. Sites around Oxford have their own page, roughly 23 miles from Mursley.

For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Mursley can sit alongside others in a wider programme.
General trades versus a specialist
There’s also the paperwork. 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.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Writing the fire-stopping specification
- Fire doors, dampers or other fire safety equipment
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.
Where we work in Mursley
- Cable penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Pipe penetrations
- Linear gaps at wall heads
When to call us in Mursley
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps. The tested detail for a linear joint states the width and movement it covers.
What tends to prompt an enquiry:
- Openings found when ceilings come down for a refit
- Non-fire-rated filler around services
- Open linear gaps along the top of fire-resisting walls
- Fire-rated sealant that has cracked or shrunk back
For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing.
What to look for in a quote
- How joint depth will be controlled
- Whether primer will be used where the manufacturer specifies it
- Are they CHAS accredited or on Constructionline?
- Proof of insurance
Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Agree the fire-stopping specification before services go in
- Keep general-purpose fillers away from compartment walls
- Ask which product is in place before decorating
- Have penetrations checked while they can still be seen
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.

Questions about Mursley
Do you cover business parks and estates near Mursley, such as Station Road Industrial Estate?
Yes. Our area takes in Mursley and its surroundings, with estates and business parks such as Station Road Industrial Estate included. Photos and a short description are enough for a first look.
Is Mursley too small for you to travel to?
No. Places such as Mursley are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can you tell us what fire stopping our building needs?
No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it, and tell you if a detail needs another product.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you have third-party installer accreditation for fire stopping?
No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we’re not the right fit for that package.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
From enquiry to sign-off
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Mursley need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- 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.
Preparing the site
- Point out parking and an unloading spot
- Point out any areas we must not close
- Make sure the joints can be reached
