Fire-rated sealant in Dedham Heath, Essex

- Gaps flagged on a fire risk assessment
- New service routes left unsealed after building work
- Door frames with gaps between frame and wall
What happens if it’s left?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Where a wall is exposed, as many are in small places like Dedham Heath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Questions from Dedham Heath
Do you work for landlords with property near Manningtree station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is Dedham Heath within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can I use normal mastic around a pipe through a fire wall?
No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Where do you work from?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.
Common problems we fix in Dedham Heath
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
The most common problems we see are:
- Fire stopping disturbed by later work
- Door frames with gaps between frame and wall
- Sealant items on a fire risk assessment action list
- Unsealed gaps where pipes and cables go through a wall
Community buildings like Parish Church of St Mary are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Photograph sealed gaps before they’re covered up
- Include fire stopping when you schedule refits
- Look in service cupboards and ceiling voids from time to time
- Keep the record of products and locations with your fire safety documents
Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Dedham Heath, the journey is planned in advance: let us know about lanes, gates and parking. 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.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in

Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist.
Workplaces and buildings in Dedham Heath
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.
Schools such as Dedham Church of England Voluntary Controlled Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Manningtree station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
