How the job changes by surface
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we’ll tell you.
How we handle fire rated sealant in Green Street
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. If you’re dealing with open joints along the top of partitions and door frames with gaps between frame and wall, we can help, on service penetrations, door frames and plasterboard & masonry alike.
In a village or hamlet like Green Street, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Leave it or put it right?
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. Where a wall is exposed, as many are in small places like Green Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

How to look after the new joints
To keep the joints looking good and working properly:
- Get damaged fire seals looked at promptly
- Check whether a sealant can be painted before decorating over it
- Tell trades working in the building that fire seals must be put back
- Check risers, ceiling voids and cupboards during building checks
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot, so ask us which we used.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
How the visit works
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a handful of gaps, and longer for a whole building, and we explain the cure time before we leave. Somewhere like Green Street needs a little journey planning: 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.
- 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.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Preparing for the visit
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit

Advice
FAQs for Green Street
I let a flat near Ingatestone station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Is Green Street within the area you cover?
Yes, Green Street is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What fire rating will the seal have?
That isn’t something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Is standard sealant good enough for a fire gap?
No. It looks sealed but won’t perform as fire stopping. A tested fire-rated product is needed and we can apply it for you.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Quotes for fire rated sealant in Green Street
Your quote is based on your job. We look at:

- Whether old sealant or filler has to be cut out
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.
What to tell us for a quote
When you call or email, it’s useful to know:
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- Roughly how big the job is
- What’s wrong with the joints now

Workplaces and buildings in Green Street
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, 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 Ingatestone station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like Church of St Mary the Virgin are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Ingatestone Infant School, gaps opened by contractors for new cabling are a common finding in schools and offices.
