Hook Green Fire Rated Sealant
We cover Hook Green for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and a one-year guarantee.

About our fire rated sealant in Hook Green
Deciding which gaps need fire stopping isn’t our role; 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. We work on plasterboard & masonry, linear gaps and door frames, and common reasons people get in touch are open gaps behind door architraves and standard silicone or caulk in a fire-stopping gap.
Somewhere as small as Hook Green, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
A 12-month guarantee comes as standard, so you are covered after we have gone.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What fire rated sealant looks like in Hook Green
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 work to the specification you’re given, installing the product to its tested details.
For buildings such as Church of St Nicholas, gaps around pipes and cables are worth checking after any building work there. Rented homes near Longfield station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Surface by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before work begins so residents know what to expect.
Your questions about fire rated sealant in Hook Green
Do you work for landlords with property near Longfield station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Can you do fire rated sealant in Hook Green?
Yes, Hook Green is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
What does fire rated sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do you take on fire stopping in schools and offices?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use. Early starts or out-of-hours work can be arranged.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
Why deal with it now?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Hook Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

How it works
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on how many gaps there are in most cases. For a village or hamlet like Hook Green, the journey is planned in advance: 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 go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Before we arrive
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Clear the area around the work

Advice
What affects the cost of fire rated sealant
There’s no set price list, because no two jobs are the same. The quote depends on:
- The number of rooms or windows
- How easy the joints are to reach
- Mould in or behind the old joints
- Working hours on commercial sites
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
What we need to know
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- Whether it has been sealed before
- Where the property is
- Roughly how big the job is
Need a quote? Please ring 0345 464 0079 or email us and tell us about the job. You’ll know what we plan to do, and what it will cost, before any work begins.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Assessing a building’s fire safety
- A wall that isn’t a fire-resisting element to begin with
- Fire doors that need new seals, closers or hardware
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Linear gaps
- Service penetrations
- Pipe & cable gaps
- Door frames
- Flats & HMOs
- Plasterboard & masonry
Do you need fire rated sealant in Hook Green?
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
Keep an eye out for any of the following:
- Gaps around pipes and cables through fire-resisting walls
- Open gaps behind door architraves
- Gaps where walls meet ceilings or slabs
- Cracked or shrunken fire-rated sealant
If you look after a building such as Sedley's Church of England Voluntary Aided Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
