Monkwood fire stopping
Sealant work in Monkwood for main contractors, managing agents and facilities managers: fire-rated and intumescent sealing of service penetrations and linear gaps, quoted at a fixed price.
- Head-of-wall gaps with no fire seal
- Non-fire-rated filler around services
- Fire seals cut back for extra cables and never reinstated

Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Different surfaces, different methods
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits, and any outside it are raised with you.
Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork normally needs a different solution set by the designer, and we’ll say if that applies.
Fire stopping in Monkwood
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you are dealing with fire-stopping items raised at inspection or handover and improvised or mixed-product fire seals, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Monkwood it comes down to the same thing: the right product in a properly prepared joint.
For a smaller site near Monkwood, 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.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Other services in Monkwood
Compartment walls and floors in Monkwood
Monkwood is about 51 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. In England, Approved Document B covers fire stopping of 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. Either way, we install the specified product to its tested detail.
Hospital estates such as Alton Community Hospital (5.5 miles north-east of Monkwood) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Offices at parks like Mansfield Business Park, 3 miles north of Monkwood, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For a building around Monkwood, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
What we need from you
- Warn occupants and staff about the work
- For older buildings, check the asbestos register before work
- Flag any permit to work we will need

Common questions from Monkwood clients
Can you work on a hospital site such as Alton Community Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Monkwood too small for you to travel to?
Not at all: smaller places are covered as well as 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.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Will you sign off the seals for us?
No. Approval sits with the designer, principal designer or building control. We will confirm the product and detail installed and agree any further records when we quote.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Is fire stopping in Scotland covered by different guidance?
Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.
Leave it or put it right?
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. One visit to deal with every failing joint makes more sense than several trips to a place like Monkwood. Photos of every joint help us quote for the whole job.

Do you need fire stopping in Monkwood?
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls.
Things that typically lead to an enquiry:
- Openings left by services added after handover
- Penetration schedules that need working through
- Fire stopping installed outside its tested range
- Openings found when ceilings come down for a refit
For a building such as Monkwood Mission Church, new heating or data runs are the usual reason penetrations need sealing.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint
- How they’ll work around occupants
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Who will actually carry out the work
Quoting for work in Monkwood
A fixed quote reflects the actual work. It takes account of:
- Distance, for remote addresses
- The product specified
- Phasing around occupants
- Access and working height
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Your programme or deadline
- Access details, including height
- Whether an asbestos survey exists
- The site address and postcode
To get a fixed quote, ring 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Brief every trade that openings they make must be sealed
- Foam or ordinary sealant is never a fire-seal repair
- Treat an open penetration as a priority repair
- Record which product was used where
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.
