Fire rated sealant for homes and businesses in Ashley Green
We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. Common call-outs are for fire stopping disturbed by later work and ordinary sealant used where a fire-rated product was needed, across flats & HMOs, pipe & cable gaps and door frames.
In a village or hamlet like Ashley Green, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
All our work comes with our one-year guarantee.

Why act early in Ashley Green
Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Around Ashley Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Ashley Green questions
Do you work for landlords with property near Berkhamsted station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Do you cover Ashley Green for fire rated sealant?
Yes, Ashley Green is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
What’s the difference between intumescent and fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you tell me how many minutes the seal will last?
We don’t certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and giving you a record of where it went.
Is the work guaranteed?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start.

Related advice
When to call us in Ashley Green
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.
Look out for these signs:
- Gaps around pipes and cables through fire-resisting walls
- New service routes left unsealed after building work
- Open joints along the top of partitions
- Door frames with gaps between frame and wall
Rented homes near Berkhamsted station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Questions to ask before booking
- What preparation is included
- What insurance they hold
- How much experience the applicator has
- What guarantee comes with the work

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Flag any open gap you spot round a pipe or cable
- Include fire stopping when you schedule refits
- Include hidden areas like risers in routine checks
- Make resealing part of every contractor’s brief
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is usually a straightforward job.
What sealant work can’t fix
We won’t take on work that won’t last, so these are the limits:
- Assessing a building’s fire safety
- Fire doors that need new seals, closers or hardware
- A wall that isn’t a fire-resisting element to begin with
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.
Joints and surfaces we work on

Commercial buildings in Ashley Green
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
If you look after a church, hall or community building such as Parish Church of St John the Evangelist, service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as Ashlyns School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Surface by surface
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.
