When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Gaps in walls that were never built as compartment walls
- Deciding what a wall or floor needs, which belongs to the designer
- Plastic pipes whose detail calls for a collar or wrap

Fire stopping in Mockbeggar, done properly
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail, not a rule of thumb. Site teams most often ask us about penetration schedules that need working through and damaged fire seals in risers and voids, on cable penetrations, pipe penetrations and service gaps in risers. A single leaking joint is often how a building in Mockbeggar first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Barn and farm-building conversions near places like Mockbeggar 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 ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How a job runs
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Mockbeggar, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Tell staff and tenants when we will be in
- Share the asbestos register for older buildings
- Agree which areas must stay open
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Advice
What the job involves on each surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter and we work within those limits.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we will never swap a specified collar for sealant.
Leave it or put it right?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. One visit to deal with every failing joint makes more sense than several trips to a place like Mockbeggar, rather than one at a time. Send photos of each area and we will quote for the lot.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Why appoint us
- A Constructionline member, so easy to vet

Fire-rated sealing for Mockbeggar buildings
Approved Document B is the English guidance that covers fire stopping around 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. We install whatever has been specified, to the product’s tested detail.
Office fit-outs on sites such as Headlands Business Park (to the south of Mockbeggar) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. In a building such as Church of St Martins, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Your questions answered
Is Mockbeggar off your patch?
No. Places such as Mockbeggar are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Would you work within a site like Fordingbridge Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
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.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
After the work
To get the most from the new sealant:
- Keep general-purpose fillers away from compartment walls
- File the specified details where the next contractor can find them
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Ask which product is in place before decorating
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.
Do you need fire stopping in Mockbeggar?
Openings in fire-resisting walls typically appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
Most enquiries start with one or more of the following:
- Fire stopping installed outside its tested range
- Open linear gaps along the top of fire-resisting walls
- Fire sealant pulled out of the opening
- Expanding foam used as fire stopping
Wherever services are added at a hospital such as Fordingbridge Hospital (to the north of Mockbeggar) the compartment line has to be made good with the specified product.
