Fire rated sealant in Woodrow
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. We are often asked to deal with door frames with gaps between frame and wall and gaps flagged on a fire risk assessment, across door frames, flats & HMOs and linear gaps.
For holiday lets, converted business premises or a community building near Woodrow, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

How it works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job usually takes anything from a few hours to several days, depending on how many gaps there are, and we tell you how long to leave it before we go. For a village or hamlet like Woodrow, 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.
- 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.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- File the fire-stopping record where your assessor can find it
- Do not paint over fire sealant until it has cured
- Plan fire stopping into any work that goes through walls or floors
- Get damaged fire seals looked at promptly
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint, so ask us which we used.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Construction that doesn’t provide fire resistance on its own
- Issuing a fire rating or certificate for a building
- Doors that are not fire doors in the first place
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
Joints and surfaces we work on

Questions from Woodrow
Is Woodrow within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Woodrow for fire rated sealant?
Yes, Woodrow 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 let us know what needs doing.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
What should I tell you?
Let us know what needs doing and where, with pictures by email if possible. If we need more, we will ask.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
What fire rated sealant looks like in Woodrow
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.
If you look after a church, hall or community building such as Church of the Holy Trinity, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Curzon Church of England Combined School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. For landlords with property near Amersham station, any gap left by new services in shared walls should be closed with a fire-rated product.

Surface by surface
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run so there are no open sections left.
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.
Leave it or put it right?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. Around Woodrow, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
If you do try it yourself, take your time over the 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.
