Fire stopping in Althorne
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Althorne. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are seals that don’t match their tested detail and fire-rated sealant that has cracked or shrunk back. Searching for sealant specialists in Althorne? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around smaller places like Althorne, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Questions about Althorne
Is Althorne off your patch?
Not at all. Althorne is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Do you cover business parks and estates near Althorne, such as Red Lions Business Centre?
Yes, sites like Red Lions Business Centre are within our area, along with the rest of Althorne. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Do you approve fire stopping for building control?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.

Compartments and services around Althorne
Althorne lies roughly 38 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. In England, Approved Document B covers fire stopping of 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.
For a building such as Parish Church of St Andrew, new heating or data runs are the usual reason penetrations need sealing.

What we are called out for in Althorne
A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position and has to be removed.
Any of the following is a good reason to get the joints checked over:
- Head-of-wall gaps with no fire seal
- Hidden openings found during inspections
- Expanding foam used as fire stopping
- Fire seals cut back for extra cables and never reinstated
Tenant changes at parks like Red Lions Business Centre (1.2 miles north-west of Althorne) bring new data and services, and openings through fire-resisting walls need the specified seal.

How the job changes by surface
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do and we will tell you what the detail says instead.
Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Looking after the joints
For the best life from the joints:
- Agree the fire-stopping specification before services go in
- Report damaged or disturbed seals as soon as they’re spotted
- Check with the data sheet before painting over fire sealant
- Put resealing into every M&E and fit-out package
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
