About our fire stopping in Jacob's Post
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on linear gaps at wall heads, cable penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are unsealed penetrations discovered above suspended ceilings and fire sealant pulled out of the opening. Looking for mastic applicators who cover Jacob's Post? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
A job near Jacob's Post is usually planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.

On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Jacob's Post need work, visits can be combined. A fixed quote is given before anything starts.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Before we start on site
- Share the asbestos register for older buildings
- Share your working hours and any access restrictions
- Clear stock, furniture or equipment away from the joints

Owners, agents and contractors
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Jacob's Post can form part of a wider programme across West Sussex.
Why deal with it now?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Converted and older buildings near places like Jacob's Post tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

What else we do in Jacob's Post
When to call us in Jacob's Post
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
Site and facilities staff are often the first to spot these:
- Service penetrations left open after M&E works
- Open linear gaps along the top of fire-resisting walls
- Fire seals cut back for extra cables and never reinstated
- Penetration schedules that need working through
For a hospital such as The Dene Hospital, which lies west of Jacob's Post, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.
Questions to ask before you book
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- What level of public liability insurance do they hold?
- Health and safety accreditation such as CHAS
- Whether old or failed sealant will be cut out, not overlaid
What sets the cost
Before we quote, we look at:
- Phasing around occupants
- The product specified
- How much existing material needs removing
- Distance, for remote addresses
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Whether the building will be occupied during the work
- Where the site is, with the postcode
- Drawings or a marked-up plan, if available
- Your programme or deadline
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or use the quote form.
Penetration seals near Jacob's Post
Jacob's Post has two care or nursing homes no more than 2 miles away. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Halls and meeting rooms at places like Providence Strict Baptist Chapel sometimes gain new services, and any compartment wall crossed needs the specified seal. At a university such as University of Sussex, 4.5 miles east of Jacob's Post, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Questions about Jacob's Post
Can you work on a hospital site such as The Dene Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Does your area include sites such as Ashwyn Business Centre, near Jacob's Post?
Yes. Our area takes in Jacob's Post and its surroundings, with estates and business parks such as Ashwyn Business Centre included. A few photos and the unit address let us price the work.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Is sealant suitable for all service openings?
No. A sealant’s evidence covers set services, gaps and wall or floor types. If an opening falls outside, it needs another solution, specified by your designer.
Can you reseal penetrations after our M&E works?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see and we close them with the specified product.
Do you offer coloured sealant?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Surface by surface
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance.
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
