About our fire stopping in Fawley
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on cable penetrations, pipe penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are fire sealant pulled out of the opening and damaged fire seals in risers and voids. Facilities teams, main contractors and managing agents in Fawley tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Rural conversions around Fawley can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Surface by surface
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.

General trades versus a specialist
Certain joints really need a specialist: for instance 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.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Jobs in and around smaller places like Fawley are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.

Advice
Why deal with it now?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Older rural buildings around Fawley move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.

Compartments and services around Fawley
For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
In a hotel such as Falcon Hotel (less than half a mile south-west of Fawley), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. On a hospital site such as Coldeast, which lies north-east of Fawley, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

FAQs: Fawley
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Fawley?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Is Fawley off your patch?
No. Places such as Fawley are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
What do you charge?
There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you need fire stopping in Fawley?
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.
Common reasons buildings call us in:
- Non-fire-rated filler around services
- Seals that don’t match their tested detail
- Old intumescent sealant that has split away
- Open linear gaps along the top of fire-resisting walls
Tenant changes at parks like Glenmore Business Park, 2.1 miles to the north-west of Fawley, bring new data and services, and openings through fire-resisting walls need the specified seal.
