What we are called out for in Hethe
Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access usually bring them to light.
These are often picked up first by site or facilities staff:
- Openings found when ceilings come down for a refit
- Seals disturbed by maintenance and left open
- Fire sealant pulled out of the opening
- Expanding foam used as fire stopping
For a hospital such as Bicester Community Hospital, which lies south of Hethe, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.
What your quote should include
- The named product and why it was chosen
- Whether their applicators hold CSCS cards
- The terms of the workmanship guarantee
- Whether primer will be used where the manufacturer specifies it
About our fire stopping in Hethe
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are unsealed joints where partitions meet the slab and builders’ foam or ordinary silicone in compartment walls. Facilities teams, main contractors and managing agents in Hethe tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Barn and farm-building conversions near places like Hethe often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Aftercare for building managers
To get the most from the new sealant:
- Settle who seals which penetrations at the start of a project
- Ask which product is in place before decorating
- Include service cupboards in routine inspections
- Treat an open penetration as a priority repair
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
How a job runs
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly.

Advice
Why act early in Hethe
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed. For buildings around smaller places like Hethe, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Surface by surface
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Common questions from Hethe clients
Is hospital work, at somewhere like Bicester Community Hospital, something you do?
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.
What does the BS 476 change mean for fire-rated sealant in Hethe?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Is the work guaranteed?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
How long does a job like this take?
It depends on the scope, but the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.

At about 55 miles from central London, Hethe is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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.
