When to call us in Crosspost
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
Most people get in touch after spotting something like this:
- Gaps left after a refit or conversion
- Ordinary sealant used where a fire-rated product was needed
- Gaps where walls meet ceilings or slabs
- Seals cut through by electricians, plumbers or data installers
If you let a flat or house near Wivelsfield station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
What your quote should include
- Whether all the old sealant comes out first
- When the joint can take water or movement
- How much experience the applicator has
- How the joint is cleaned and prepared
Fire rated sealant in Crosspost
Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over. We work on flats & HMOs, linear gaps and plasterboard & masonry, and people most often call us about open joints along the top of partitions and damaged fire sealant left by other trades.
For holiday lets, converted business premises or a community building near Crosspost, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

The process
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes from a few hours to a few days, depending on the number of gaps and the access in most cases. Somewhere as small as Crosspost, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
How to prepare
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on

What else we do in Crosspost
Workplaces and buildings in Crosspost
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details. Crosspost has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
If you look after a church, hall or community building such as St Mary Magdalene's Church, gaps around pipes and cables are worth checking after any building work there. Managing a site like Bolney CofE Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

- Construction that doesn’t provide fire resistance on its own
- Big openings where sealant alone isn’t the tested solution
- Issuing a fire rating or certificate for a building

Surfaces we seal
- Door frames
- Linear gaps
- Flats & HMOs
- Pipe & cable gaps
- Plasterboard & masonry
- Service penetrations
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Quotes for fire rated sealant in Crosspost
We do not publish a price list, because no two jobs are the same. What we look at:
- Mould in or behind the old joints
- Which sealant suits the joint
- The old material and how stubborn it is
- Working hours on commercial sites

What we need to know
When you call or email, it’s useful to know:
- If someone has resealed it before
- Where the property is
- Any access issues, like height or stairs
- The problem you’ve noticed

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- File the fire-stopping record where your assessor can find it
- Include fire stopping when you schedule refits
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Check risers, ceiling voids and cupboards during building checks
Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.
Surface by surface
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run so there are no open sections left.
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard for each gap size.
