Fire Rated Sealant in Finstock
Our applicators work in Finstock on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Damaged fire sealant left by other trades
- Door frames with gaps between frame and wall
- Unsealed gaps where pipes and cables go through a wall
The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for a handful of gaps, and longer for a whole building from start to finish. Somewhere like Finstock needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided 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.
- Any non-fire-rated filler is removed.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
How to prepare
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

Advice
How we handle fire rated sealant in Finstock
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. Typical jobs include holes left by a change of layout and ordinary sealant used where a fire-rated product was needed, on flats & HMOs, plasterboard & masonry and service penetrations.
Work in a small place like Finstock is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.
All our work comes with our one-year guarantee, wherever you are in Oxfordshire.

Workplaces and buildings in Finstock
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.
Managing a site like Finstock Church of England Primary School? Then fire-stopping around service openings should be restored whenever new services go in. If you let a flat or house near Finstock station, any gap left by new services in shared walls should be closed with a fire-rated product.

How do I get a quote for fire rated sealant in Finstock?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or email us with a short description of the job.
Can ordinary silicone be used in a fire-stopping gap?
No. It looks sealed but will not perform as fire stopping. Use a product tested for that gap and service.
Do you take on fire stopping in schools and offices?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use, with access planned around residents or staff. Out-of-hours work can be arranged if that suits the building.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Common problems we fix in Finstock
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.
Most people get in touch after spotting one of these:
- Old fire sealant that has split or come away
- Unsealed gaps around fire door frames
- Standard silicone or caulk in a fire-stopping gap
- Sealant items on a fire risk assessment action list
For buildings such as Church of the Holy Trinity, older buildings that have had new heating or wiring often have service gaps worth checking.
Questions to ask before booking
- Who does the work, and how experienced they are
- How hidden problems are handled
- What insurance they hold
- What preparation is included
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Different surfaces, different methods
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.
Flats and HMOs
In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before work begins to keep disruption down.
What sealant work can’t fix
We will not take on work that won’t last, so these are the limits:
- Large holes that need a different fire-stopping system
- A wall that is not a fire-resisting element to begin with
- Doors that are not fire doors in the first place
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

What else we do in Finstock
Leave it or put it right?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. Where a wall is exposed, as many are in small places like Finstock, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
