Fire Rated Sealant in John's Cross
We cover John's Cross for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.

About our fire rated sealant in John's Cross
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you have cracked or shrunken fire-rated sealant and unsealed gaps where pipes and cables go through a wall, we can help, whatever the surface.
If you have holiday lets, a converted barn used for business or a community building near John's Cross, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
There’s a 12-month guarantee on every job, large or small.

When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Certifying a building or signing off its fire safety
- A wall that is not a fire-resisting element to begin with
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Surface by surface
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.

What else we do in John's Cross
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we are fully insured for the work.
Workplaces and buildings in John's Cross
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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
For landlords with property near Robertsbridge station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as The Parish Church of All Saints, gaps around pipes and cables are worth checking after any building work there.

Why act early in John's Cross
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing once someone inspects it. Around John's Cross, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Signs you need fire rated sealant in John's Cross
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried.
Most people get in touch when they notice something like this:
- Sealant items on a fire risk assessment action list
- Gaps where walls meet ceilings or slabs
- Old fire sealant that has split or come away
- Fire stopping disturbed by later work
For site and facilities teams at buildings such as Vinehall School, service openings in fire-resisting walls need checking after any refurbishment.
Questions to ask before booking
- How long the guarantee is
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- How much experience the applicator has

Typically it takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy.

- 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.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we are working on
