Leave it or put it right?
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. In a small place like Thorney, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Fire rated sealant in Thorney, 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, with a record of the products and locations if you need one. If you are dealing with open gaps behind door architraves and open joints along the top of partitions, we can help, whatever the surface.
In a village or hamlet like Thorney, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
Our work is backed for twelve months, in Thorney and everywhere else we cover.

What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere like Thorney needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Before we arrive
- Mention any parking rules near the property
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

Signs you need fire rated sealant in Thorney
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it isn’t a fire-rated seal.
Any of these means the joints need attention:
- New service routes left unsealed after building work
- Unsealed gaps around fire door frames
- Sealant items on a fire risk assessment action list
- Gaps filled with a product that isn’t fire-rated
Rented homes near Iver station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you certify the fire stopping?
We don’t give ratings or certificates for our work. Your specification sets the requirement, and we apply a product tested for it, recording the locations and products.
Can you fill the gap behind a fire door frame?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months, large or small.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Fire rated sealant in Thorney: local notes
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.
If you look after a building such as St Catherine Catholic Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as St. Leonard's, older buildings that have had new heating or wiring often have service gaps worth checking.

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Different surfaces, different methods
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment, flat by flat if needed.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
