Fire stopping for West Hill sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Treat an open penetration as a priority repair
- Record which product was used where
- Foam or ordinary sealant is never a fire-seal repair
- Have penetrations checked while they can still be seen
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
Fire stopping in West Hill, done properly
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 job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. Site teams most often ask us about unsealed joints where partitions meet the slab and service penetrations left open after M&E works, on pipe penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors. Whether you call it commercial sealant work, mastic application or joint sealing, the work in West Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Buildings in a smaller place such as West Hill that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

More services for West Hill
Different surfaces, different methods
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.
When to bring in a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
From enquiry to 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, then reopened once the sealant allows before we move to the next. Work in places the size of West Hill is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Share your working hours and any access restrictions
- Let building users know which areas are affected
- Tell us what induction or permit system the site runs

What we’re called out for in West Hill
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
Look out for the following:
- Hidden openings found during inspections
- Openings left by services added after handover
- Fire seals cut back for extra cables and never reinstated
- Head-of-wall gaps with no fire seal
In a retail centre such as Churchill Square, which lies south of West Hill, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.

Compartments and services around West Hill
A 2-mile radius around West Hill takes in a good number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail.
At a healthcare site like The Montefiore Hospital, which lies west of West Hill, new services through compartment walls are a constant, and each needs the specified seal. At a university such as University of Brighton Moulesecoomb Campus (1.5 miles north-east of West Hill), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

West Hill: questions and answers
Will you work in a care home in West Hill without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.
Can you seal around new services in a hotel near West Hill?
Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
How long does a job like this take?
It depends on the scope, but the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Signing off or certifying a building’s fire stopping
- Plastic pipes whose detail calls for a collar or wrap
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, phone 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
Joints and surfaces we work on
