East Hill Fire Rated Sealant
We cover East Hill for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Open joints along the top of partitions
- Open holes round services passing through fire walls
- Joints picked up in a fire-stopping survey
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Fire rated sealant in East Hill
We can work through a building room by room or floor by floor. That record is useful for your files and for whoever looks at the building next. We work on pipe & cable gaps, linear gaps and flats & HMOs, and common reasons people get in touch are linear gaps at the head of walls and gaps flagged on a fire risk assessment.
For holiday lets, converted business premises or a community building near East Hill, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
All our work comes with our one-year guarantee.

Surface by surface
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.
Flats and HMOs
Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance.
Honest limits
A few problems are outside what sealant work can do:
- Fire risk assessments, which need a qualified assessor
- Sign-off of the building, which sits with building control or your assessor
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
Surfaces we seal
- Pipe & cable gaps
- Plasterboard & masonry
- Service penetrations
- Flats & HMOs
- Linear gaps
- Door frames
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Look in service cupboards and ceiling voids from time to time
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Make resealing part of every contractor’s brief
- Flag any open gap you spot round a pipe or cable
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded.
What fire rated sealant looks like in East Hill
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.
Community buildings like Church of Saint Mary the Virgin are part of the picture too: gaps around pipes and cables are worth checking after any building work there. For landlords with property near Shoreham (Kent) station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

FAQs for East Hill
I let a flat near Shoreham (Kent) station. Can you help?
Yes. We work for letting agents and landlords as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Do you cover East Hill for fire rated sealant?
Yes, East Hill is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Can you tell me how many minutes the seal will last?
We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.
What does intumescent mean?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one of the options. We use whichever the specification and tested details call for.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.

For landlords and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
The process
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like East Hill needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Before we arrive
- Let us know about parking restrictions
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive

Advice
What happens if it’s left?
Sealant isn’t the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. Where a wall is exposed, as many are in small places like East Hill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.
