Fire rated sealant in Chesterton
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. If you’re dealing with seals cut through by electricians, plumbers or data installers and gaps left after a refit or conversion, we can put it right, whatever the surface.
For a small place like Chesterton, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
Your job is guaranteed for a year, as with all our work.

Chesterton: your questions answered
Do you work for landlords with property near Bicester Village station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you take on hotel work around Chesterton?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Do you do fire sealant around door frames?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
When to call us in Chesterton
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
The problems people normally mention when they call include:
- Fire seals that have cracked with movement
- Gaps filled with a product that is not fire-rated
- Fire stopping disturbed by later work
- New service routes left unsealed after building work
For site and facilities teams at buildings such as Chesterton Church of England Voluntary Aided Primary School, service openings in fire-resisting walls need checking after any refurbishment.
What to look for in a quote
- When the joint can take water or movement
- Whether you can choose the colour
- Who turns up on the day
- What happens if the job turns out different

What else we do in Chesterton
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep photos of seals that will be hidden
- Look in service cupboards and ceiling voids from time to time
- Make resealing part of every contractor’s brief
- Flag any open gap you spot round a pipe or cable
Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. We can tell you which product we used.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so you can show it was dealt with.
Work for landlords, hotels and businesses
If you manage several properties in or around Chesterton, several properties can go on one quote. Just tell us the addresses and what each one needs.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Chesterton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property

Why it’s worth doing now in Chesterton
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Older cottages and farmhouses around Chesterton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Different surfaces, different methods
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.
