What fire rated sealant looks like in Midhurst
Midhurst 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. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

How it works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of gaps, and longer for a whole building from start to finish. For a job in Midhurst, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- 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.

Related advice
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When to call us in Midhurst
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave doesn’t always get resealed.
Keep an eye out for these signs:
- Sealant items on a fire risk assessment action list
- Gaps around pipes and cables through fire-resisting walls
- Gaps where walls meet ceilings or slabs
- Old fire sealant that has split or come away
Community buildings like Roman Catholic Church of Divine Motherhood are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Why act early in Midhurst
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In a smaller place like Midhurst, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Looking after it afterwards
To keep the joints looking good and working properly:
- Include hidden areas like risers in routine checks
- File the fire-stopping record where your assessor can find it
- Plan fire stopping into any work that goes through walls or floors
- Keep pictures of seals that will be hidden
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
