Fire rated sealant in Chilton, done properly
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. If you have door frames with gaps between frame and wall and open joints along the top of partitions, we can put it right, whatever the surface.
If you have holiday lets, a converted barn used for business or a community building near Chilton, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
There’s a 12-month guarantee on every job, large or small.

Fire rated sealant around Chilton
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Schools such as Chilton County Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as Church of All Saints, gaps around pipes and cables are worth checking after any building work there. Letting a property close to Didcot Parkway station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

How the visit works
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on how many gaps there are in most cases. In a small place like Chilton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- 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 faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on
- Tell us if parking is tricky

Questions from Chilton
Do you cover smaller places like Chilton?
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 Chilton for fire rated sealant?
Yes. We work across London and the South East, and Chilton is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How long does the job take?
A typical job takes a few hours for a handful of gaps, and longer for a whole building, including the preparation. Your quote will say how long we expect yours to take.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
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, and the work is guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What the job involves on each surface
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified, flat by flat if needed.
Linear gaps
A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.
Why act early in Chilton
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Older cottages and farmhouses around Chilton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Looking after it afterwards
So the new joints stay in good condition:
- Photograph sealed gaps before they’re covered up
- Check whether a sealant can be painted before decorating over it
- Keep the record of products and locations with your fire safety documents
- Include fire stopping when you schedule refits
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Certifying a building or signing off its fire safety
- A wall that is not a fire-resisting element to begin with
- Deciding what fire stopping a building needs
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
