Fire-rated sealant in Sundridge, Kent
Fire-stopping gaps in Sundridge need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.

The process
On the day, we start by going over the job with you. We protect the surfaces around the joints before we start. The work usually takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Sundridge, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- 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.
How to prepare
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in

If you have door frames with gaps between frame and wall and cracked or shrunken fire-rated sealant, we can put it right, on service penetrations, linear gaps and plasterboard & masonry alike.
Work in a small place like Sundridge is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Big or small, you get the same one-year guarantee.

Workplaces and buildings in Sundridge
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For site and facilities teams at buildings such as Combe Bank School, fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Dunton Green station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Sundridge is about 3 miles west of Sevenoaks, in Kent. For fire rated sealant in and around Sundridge, please ring 0345 464 0079 or drop us an email for a quick quote.

Why deal with it now?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In a small place like Sundridge, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Common problems we fix in Sundridge
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service isn’t always sealed again.
Signs it’s time to call us include:
- Sealant items on a fire risk assessment action list
- Open gaps behind door architraves
- Holes left by a change of layout
- Unsealed gaps where pipes and cables go through a wall
If you look after a church, hall or community building such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sundridge: your questions answered
Do you cover Sundridge for fire rated sealant?
Yes, Sundridge is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Is Sundridge within the area you cover?
Yes, Sundridge is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
How long will you be here?
Most jobs take from a few hours to a few days, depending on the number of gaps and the access. We’ll confirm how long when we quote.
Can I use normal mastic around a pipe through a fire wall?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. If it’s been used, we remove it and use the right product.
Are you fully insured?
Yes. We are fully insured.
Will you assess my building’s fire safety?
No, assessment isn’t something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.
Can you tell me how many minutes the seal will last?
We don’t certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and list the locations and products for you.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Certifying a building or signing off its fire safety
- Openings too large for sealant, which need batts, boards or another system
- Fire risk assessments, which need a qualified assessor
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Joints and surfaces we work on
- Flats & HMOs
- Service penetrations
- Plasterboard & masonry
- Pipe & cable gaps
- Door frames
- Linear gaps
How to look after the new joints
A little care helps the new joints last. We recommend:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Plan fire stopping into any work that goes through walls or floors
- Store the list of sealed gaps with your building paperwork
- Tell trades working in the building that fire seals must be put back
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes.
What the job involves on each surface
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run.
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before applying the sealant.
