How we handle fire stopping in Little Waltham
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in Little Waltham. We work on joints between fire-resisting walls and floors, service gaps in risers and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are fire-rated sealant that has cracked or shrunk back and non-fire-rated filler around services. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Little Waltham is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Little Waltham, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Little Waltham: questions and answers
Could you schedule work at a campus like Anglia Ruskin University for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Will you take on work at estates like Regiment Business Park, close to Little Waltham?
Yes. Our area takes in Little Waltham and its surroundings, with estates and business parks such as Regiment Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Do you have third-party installer accreditation for fire stopping?
No, and we’d rather be clear about that. Some clients require third-party installer schemes even though the law doesn’t, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Is BS 476 being phased out?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence. In Scotland, the Technical Handbook sets its own guidance, with clause 2.1.14 covering service penetrations.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact.
Can you tell us what fire stopping our building needs?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is installing what they specify, to the product’s tested detail.
Do you work in Little Waltham?
Yes. We take on work across Little Waltham, and the same phone number covers every area.
Penetration seals near Little Waltham
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. What we install is set by the specification, and it goes in to the tested detail. Central London is about 32 miles from Little Waltham. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
Offices at parks like Regiment Business Park (to the south-east of Little Waltham) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Residences at universities like Anglia Ruskin University, 3.2 miles to the south of Little Waltham, have compartment walls that must be resealed whenever services change.

Diagnose, treat, sign off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. For work around Little Waltham, 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.
- We read the specification, drawings or penetration schedule you send.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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
- Confirm the product named in the specification
- Tell us which areas need to stay in use
- Point out parking and an unloading spot

Surface by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point against the detail’s limits.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.
What we’re called out for in Little Waltham
Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped and the opening isn’t always resealed.
Any of the following is a good reason to get the joints checked over:
- Unsealed openings around new pipes and cables
- Penetration schedules that need working through
- Improvised or mixed-product fire seals
- Seals disturbed by maintenance and left open
For a hotel such as Channels Hotel, 1.3 miles south-east of Little Waltham, penetration seals are worth checking after any refit or services upgrade.

- How the joint faces will be prepared and primed
- Proof of insurance

Leave it or put it right?
Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Around Little Waltham, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

When it isn’t the sealant
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Fire risk assessments, a job for a competent assessor
- Gaps in walls that were never built as compartment walls
- Large openings beyond what any sealant detail covers
Not sure which it is? You can ring 01277 525 020 or email us and we will tell you honestly.
Where we work in Little Waltham
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Joints between fire-resisting walls and floors
After the work
For the best life from the joints:
- Have penetrations checked while they can still be seen
- Ask the designer to confirm details early on refits
- Record which product was used where
- Include service cupboards in routine inspections
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
