- Old fire sealant that has split or come away
- Linear gaps at the head of walls
- Holes left by a change of layout
What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of gaps, and longer for a whole building. For a job in Sandy Cross, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- We record the locations and products used for your records.
Preparing for the visit
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
- Move anything stored near the joints

Fire rated sealant in Sandy Cross, done properly
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you are dealing with unsealed gaps around fire door frames and gaps where walls meet ceilings or slabs, we can put it right.
For a pub, café, guest house or shop in or near Sandy Cross, its washrooms and kitchen need the same sealant care as any big building, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
All our work is covered by a 12-month guarantee.

Questions from Sandy Cross
Do you cover smaller places like Sandy Cross?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is there a guarantee on fire rated sealant in Sandy Cross?
All our work, in Sandy Cross and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you offer different sealant colours?
Usually, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before any work starts.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use.
How do I get a quote for fire rated sealant in Sandy Cross?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or send us an email with a short description of the job.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Are you insured?
Yes. We’re fully insured for every job we do.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Quotes for fire rated sealant in Sandy Cross
Every job gets its own quote. This is what makes a difference:
- Working hours on commercial sites
- The number and length of the joints
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
What to tell us for a quote
When you call or email, it’s useful to know:
- What’s wrong with the joints now
- The address or postcode of the job
- Whether it’s a home or a business
- If someone has resealed it before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
What the job involves on each surface
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service against the product’s tested range.
How to look after the new joints
To keep the joints looking good and working properly:
- File the fire-stopping record where your assessor can find it
- Keep pictures of seals that will be hidden
- Never patch a fire seal with standard sealant
- Get damaged fire seals looked at promptly
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

Signs you need fire rated sealant in Sandy Cross
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried.
These are the problems we are asked about most:
- Linear gaps at the head of walls
- Seals cut through by electricians, plumbers or data installers
- Unsealed gaps where pipes and cables go through a wall
- Holes left by a change of layout
If you look after a church, hall or community building such as St Richards Church, service openings in its walls need the right fire-rated sealant, as in any building.

Why it’s worth doing now in Sandy Cross
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. Around Sandy Cross, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Fire risk assessments, which need a qualified assessor
- Certifying a building or signing off its fire safety
- Fire doors that need new seals, closers or hardware
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.
