When to call us in Glympton
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.
These are the problems we’re asked about most:
- Ordinary sealant used where a fire-rated product was needed
- Unsealed gaps around fire door frames
- Gaps where walls meet ceilings or slabs
- Joints picked up in a fire-stopping survey
If you look after a church, hall or community building such as Church of St Mary, service openings in its walls need the right fire-rated sealant, as in any building.
Before booking anyone
- Is the old sealant removed completely?
- When the joint can take water or movement

Fire rated sealant in Glympton, done properly
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. We are often asked to deal with unsealed gaps where pipes and cables go through a wall and old fire sealant that has split or come away, on door frames, flats & HMOs and pipe & cable gaps.
For holiday lets, converted business premises or a community building near Glympton, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
There’s a 12-month guarantee on every job, large or small.

Common questions in Glympton
Do you cover Glympton for fire rated sealant?
Yes, Glympton is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Is Glympton within the area you cover?
Yes. Glympton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, wherever you are.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
What’s the difference between intumescent and fire-rated sealant?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can ordinary silicone be used in a fire-stopping gap?
No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service.
Fire rated sealant in Glympton: local notes
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Rented homes near Tackley station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Glympton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
Preparing for the visit
- For business premises, tell us about site rules or sign-in

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
How the job changes by surface
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.
Flats and HMOs
Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and the locations noted.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Ask which product was used before you paint
- Keep photos of seals that will be hidden
- Never patch a fire seal with standard sealant
- Look in service cupboards and ceiling voids from time to time
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is normally a straightforward job.
Why it’s worth doing now in Glympton
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. Where a wall is exposed, as many are in small places like Glympton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
