Fire-rated sealant in Upton, Oxfordshire
Our applicators work in Upton on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Gaps left after a refit or conversion
- Open holes round services passing through fire walls
- Fire stopping disturbed by later work
Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Fire rated sealant in Upton
We can work through a building room by room or floor by floor, noting the locations and products as we go. It gives you a list to keep with the building’s fire safety documents. Typical jobs include joints picked up in a fire-stopping survey and standard silicone or caulk in a fire-stopping gap, across pipe & cable gaps, flats & HMOs and plasterboard & masonry.
If you have holiday lets, a converted barn used for business or a community building near Upton, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Whatever the size of the job, it’s backed by our one-year guarantee in Upton and across Oxfordshire.

Why deal with it now?
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. In a small place like Upton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Upton: your questions answered
Do you work for landlords with property near Didcot Parkway 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 we start.
Do you cover Upton for fire rated sealant?
Yes, Upton is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Is standard sealant good enough for a fire gap?
No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed and we can apply it for you.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
What fire rating will the seal have?
We do not issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What’s the difference between intumescent and fire-rated sealant?
An intumescent sealant expands when it gets hot to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Store the list of sealed gaps with your building paperwork
- Report cracked or damaged seals as soon as you notice them
- Plan fire stopping into any work that goes through walls or floors
- Check whether a sealant can be painted before decorating over it
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.
What we do, step by step
Once we are on site, 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. Somewhere like Upton needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- We record the locations and products used for your records.
Before we arrive
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts

Fire rated sealant around Upton
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
Community buildings like 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. Letting a property close to Didcot Parkway station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Common problems we fix in Upton
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
The most common problems we see are:
- Ordinary sealant used where a fire-rated product was needed
- Open holes round services passing through fire walls
- Sealant items on a fire risk assessment action list
- Seals cut through by electricians, plumbers or data installers
Schools such as Blewbury Endowed Church of England Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
