Compartments and services around Deddington
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. The area within 2 miles of Deddington holds a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
At a healthcare site like Horton General Hospital, 5 miles to the north of Deddington, new services through compartment walls are a constant, and each needs the specified seal. Hotels such as Deddington Arms Hotel, under half a mile to the east of Deddington, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

About our fire stopping in Deddington
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail, not a rule of thumb. The enquiries we see most involve builders’ foam or ordinary silicone in compartment walls and fire seals cut back for extra cables and never reinstated, across linear gaps at wall heads, cable penetrations and small duct penetrations where the tested detail allows. Looking for mastic applicators who cover Deddington? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Surface by surface
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range.

When to call us in Deddington
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in.
Most enquiries start with something like this:
- Damaged fire seals in risers and voids
- Expanding foam used as fire stopping
- Penetration schedules that need working through
- Fire stopping installed outside its tested range
Holiday works at schools like Deddington Church of England Primary School often leave service openings to seal before pupils return.

What happens if it’s left?
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Around Deddington, 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.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. For work around Deddington, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Make sure the joints can be reached
- Send your site hours and access windows
- Confirm the product named in the specification
