What happens on the day
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on how many gaps there are for a typical job. In a small place like Balcombe, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Preparing for the visit
- Clear items away from the joints we’re working on
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Flag any open gap you spot round a pipe or cable
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Allow for resealing whenever new services are run
- Store the list of sealed gaps with your building paperwork
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens if it’s left?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Where a wall is exposed, as many are in small places like Balcombe, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

Signs you need fire rated sealant in Balcombe
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
The problems people generally mention when they call include:
- Unsealed gaps where pipes and cables go through a wall
- Fire seals that have cracked with movement
- Ordinary sealant used where a fire-rated product was needed
- Linear gaps at the head of walls
Rented homes near Balcombe station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
What your quote should include
- Is VAT in the price?
- Whether they’re fully insured
- Whether all the old sealant comes out first
- Whether the sealant suits the joint
Different surfaces, different methods
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
Commercial buildings in Balcombe
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
If you look after a building such as Balcombe CofE Controlled Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as The Parish Church of St Mary, gaps around pipes and cables are worth checking after any building work there.

No, assessment is not something we do. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.

Yes. There’s a 12-month guarantee on every job, wherever you are.
