About our fire rated sealant in Great Baddow
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. We work on plasterboard & masonry, flats & HMOs and linear gaps, and the jobs we see most are linear gaps at the head of walls and gaps around pipes and cables through fire-resisting walls.
Commercial work around a smaller place like Great Baddow usually means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Signs you need fire rated sealant in Great Baddow
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
The problems people normally mention when they call include:
- Unsealed gaps around fire door frames
- Open joints along the top of partitions
- Joints picked up in a fire-stopping survey
- Cracked or shrunken fire-rated sealant
Community buildings like Church of St Mary are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

The process
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work generally takes anything from a few hours to several days, depending on how many gaps there are. A visit to Great Baddow is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- 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.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Clear items away from the joints we’re working on

Looking after it afterwards
Aftercare is simple:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Plan fire stopping into any work that goes through walls or floors
- Get damaged fire seals looked at promptly
- Take pictures of fire stopping before ceilings or boxing go back
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the job gets bigger.
When something else is needed
In fairness, some problems need a different trade:
- Openings too large for sealant, which need batts, boards or another system
- Doors that aren’t fire doors in the first place
- Walls or floors that weren’t built to resist fire
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.

What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- The type of sealant required
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What to tell us for a quote
When you contact us, these details help:
- Photos by email, if that is easy
- Where the property is
- Any access issues, like height or stairs
- The rough size of the job
We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or send us an email and describe the job, and pictures are welcome.
Leave it or put it right?
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own and needn’t wait for anything else. In a smaller place like Great Baddow, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.
