Different surfaces, different methods
Plasterboard walls

Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run.
Fire rated sealant for homes and businesses in High Cross
We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you’re dealing with door frames with gaps between frame and wall and seals cut through by electricians, plumbers or data installers, we can help, on plasterboard & masonry, service penetrations and door frames alike.
For holiday lets, converted business premises or a community building near High Cross, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Your job is guaranteed for a year, as with all our work.

Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Fire doors that need new seals, closers or hardware
- Walls or floors that weren’t built to resist fire
- Issuing a fire rating or certificate for a building

Why it’s worth doing now in High Cross
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Older cottages and farmhouses around High Cross can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

High Cross questions
Do you cover High Cross for fire rated sealant?
Yes. We work across London and the South East, and High Cross is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
I let a flat near Petersfield station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you carry out fire risk assessments?
No, we do not assess buildings. When your assessor or designer has set out what’s needed, we will quote for the sealant work on it.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
Do you provide details of the products used?
Yes. Locations and products are written up when we finish. If you need pictures or a set layout, ask when you get a quote.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Ask every contractor to reseal any fire stopping they disturb
- Get damaged fire seals looked at promptly
- Check whether a sealant can be painted before decorating over it
- Keep general-purpose foam and caulk away from fire-stopping gaps
Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. We can tell you which product we used.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

What fire rated sealant looks like in High 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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as Church of St Peter, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Petersfield station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Managing a site like Froxfield Church of England Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.
