Fire rated sealant in Yarnton
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. If you have holes left by a change of layout and sealant items on a fire risk assessment action list, we can help, whatever the surface.
If you have holiday lets, a converted barn used for business or a community building near Yarnton, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Big or small, it’s backed by our one-year guarantee.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Commercial buildings in Yarnton
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.
For landlords with property near Oxford Parkway station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as William Fletcher Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Common questions in Yarnton
Can you do fire rated sealant in Yarnton?
Yes. We work across London and the South East, and Yarnton is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Can you help a landlord with a rental near Oxford Parkway station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Will you assess my building’s fire safety?
No, assessment is not something we do. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can I choose the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.
Do you provide details of the products used?
Yes. Every gap we seal is listed with the product used.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Surface by surface
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment room by room.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for the gap we’re sealing.
The process
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Yarnton, the journey is planned in advance: 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.
- We start with the survey or action list, checking the size and surfaces of every gap.
- 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.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Preparing for the visit
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height

Related advice
Why deal with it now?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job that does not depend on other work. Older cottages and farmhouses around Yarnton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Do you need fire rated sealant in Yarnton?
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
Look out for any of the following:
- Open joints along the top of partitions
- Open holes round services passing through fire walls
- Seals cut through by electricians, plumbers or data installers
- Gaps left after a refit or conversion
For buildings such as Church of St Bartholomew, older buildings that have had new heating or wiring often have service gaps worth checking.
