Your questions about fire rated sealant in Great Kingshill
Will you come out to Great Kingshill?
Yes. Great Kingshill is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Great Kingshill in your area for fire rated sealant?
Yes, Great Kingshill is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
What information do you need?
A short description and the location, with photos by email if possible. We will ask anything else we need to know.
What does intumescent mean?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.
Do you certify the fire stopping?
We do not issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Make resealing part of every contractor’s brief
- Plan fire stopping into any work that goes through walls or floors
- Don’t paint over fire sealant until it has cured
- Look in service cupboards and ceiling voids from time to time
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
Fire rated sealant around Great Kingshill
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Community buildings like Church of the Good Shepherd are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like Great Kingshill Church of England Combined School? Then service openings in fire-resisting walls need checking after any refurbishment.

What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Large holes that need a different fire-stopping system
- Issuing a fire rating or certificate for a building
- A wall that is not a fire-resisting element to begin with
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
Joints and surfaces we work on
- Plasterboard & masonry
- Pipe & cable gaps

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy.

- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.

Related advice
Do you need fire rated sealant in Great Kingshill?
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where walls meet ceilings or slabs
- Unsealed gaps where pipes and cables go through a wall
- Seals cut through by electricians, plumbers or data installers
- Fire seals that have cracked with movement
Letting a property close to Great Missenden station? Then any gap left by new services in shared walls should be closed with a fire-rated product.
What to look for in a quote
- What the cure time is
- Whether you can choose the colour
- Who turns up on the day
- Whether the sealant suits the joint
What happens if it’s left?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Older cottages and farmhouses around Great Kingshill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
