About our fire stopping in Cassington
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal rather than guesswork. If you have non-fire-rated filler around services and seals that don’t match their tested detail, we can help, on cable penetrations, small duct penetrations where the tested detail allows and service gaps in risers alike. Most enquiries from Cassington start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Barn and farm-building conversions near places like Cassington often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Cassington: questions and answers
Could you schedule work at a campus like University Field Station for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Cassington off your patch?
No. Places such as Cassington are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Is BS 476 being phased out?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, though transitional rules apply. Scotland follows its own Technical Handbook.
Will fire-rated sealant work on every penetration?
No. A sealant’s evidence covers set services, gaps and wall or floor types. If an opening falls outside, it needs another solution, specified by your designer.
Can you reseal penetrations after our M&E works?
Yes, where there is a specification for those walls and floors. New services after M&E works often breach existing seals, and we reseal them to the specified detail.
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Building owners, agents and FMs in Cassington
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

What sets the cost
A fixed quote reflects the actual work. It allows for:
- Travel to remote or island sites
- The total length or number of joints
- Joint width, depth and condition
- Working within restricted access windows
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- Asbestos survey details if the building is older
- The site address and postcode
- How the joints are reached, and at what height
- The product your specification calls for
To get a fixed quote, give us a call on 01277 525 020 or use the quote form with the site address and an outline of the work. You can also send details through our quote form.
After the work
A few simple habits keep the new joints working:
- Keep product data and details in the fire safety file
- Keep general-purpose fillers away from compartment walls
- Have penetrations checked while they can still be seen
- Treat an open penetration as a priority repair
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
Penetration seals near Cassington
Cassington is about 57 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
In a building such as Church of St Peter, any service penetration through a fire-resisting wall should be sealed to the specified detail. Wherever services are added at a hospital such as Radcliffe Infirmary, 4.1 miles to the south-east of Cassington, the compartment line has to be made good with the specified product. On a site such as Oasis Business Park (1.9 miles south-west of Cassington), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Signing off or certifying a building’s fire stopping
- Fire doors, dampers or other fire safety equipment
If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
