Fire-rated sealant in Hattingley, Hampshire
Our applicators work in Hattingley on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly.

Fire rated sealant in Hattingley, done properly
Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. We work on pipe & cable gaps, plasterboard & masonry and service penetrations, and people most often call us about seals cut through by electricians, plumbers or data installers and holes left by a change of layout.
Work in a small place like Hattingley is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
We stand behind the work with a one-year guarantee.

What the job involves on each surface
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 measure the gap at its widest point against the product’s tested range.
How we quote for fire rated sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many rooms, windows or areas are involved
- Whether the work is at height
- The type of sealant required
- Whether there’s mould to deal with
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it has been sealed before
- Where the job is, and your postcode
To get a quote, phone 0345 464 0079 or drop us an email with the location and a short description of the problem. You will have a clear quote before work begins.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What happens if it’s left?
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We will say so if a gap needs something other than sealant. Around Hattingley, older homes often have timber in their 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. You will know the price before we begin.

Fire rated sealant around Hattingley
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 are given, installing the product to its tested details.
If you look after a church, hall or community building such as Church of St Andrew, gaps around pipes and cables are worth checking after any building work there.

Looking after it afterwards
Looking after new joints is easy:
- File the fire-stopping record where your assessor can find it
- Plan fire stopping into any work that goes through walls or floors
- Do not paint over fire sealant until it has cured
- Tell trades working in the building that fire seals must be put back
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes.
Hattingley: your questions answered
Will you come out to Hattingley?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Hattingley in your area for fire rated sealant?
Yes. We work across London and the South East, and Hattingley is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job. Somewhere as small as Hattingley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- 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.
How to prepare
- Move anything stored near the joints
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit
How to get a quote
We quote each job on its own. Just ring 0345 464 0079 or email us with the details, and pictures are welcome.

Signs you need fire rated sealant in Hattingley
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
People generally contact us when they notice something like this:
- Standard silicone or caulk in a fire-stopping gap
- Door frames with gaps between frame and wall
- New service routes left unsealed after building work
- Old fire sealant that has split or come away
Schools such as Medstead Church of England Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
