Common call-outs are for holes left by a change of layout and open holes round services passing through fire walls, across door frames, linear gaps and pipe & cable gaps.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Allow for resealing whenever new services are run
- File the fire-stopping record where your assessor can find it
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Take photos of fire stopping before ceilings or boxing go back
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the list grows.
Commercial buildings in Chilworth
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 are given, installing the product to its tested details.
For site and facilities teams at buildings such as Cantell School, service openings in fire-resisting walls need checking after any refurbishment. Rented homes near Swaythling station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Your questions about fire rated sealant in Chilworth
Do you cover smaller places like Chilworth?
Yes, Chilworth is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do fire rated sealant in Chilworth?
Yes, Chilworth is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Is standard sealant good enough for a fire gap?
No. It might close the gap, but it isn’t a fire-rated seal. A tested fire-rated product is needed, or ask us to do it.
Where are you based?
We work from Crawley. We cover Chilworth and the rest of Southampton, along with the rest of our area.
Can you work in occupied buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.
Landlords, agents and businesses in Chilworth
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Leave it or put it right?
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Older cottages and farmhouses around Chilworth can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

How the job changes by surface
Door frames
A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
