Fire stopping for commercial buildings in Old Netley
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. Site teams most often ask us about old intumescent sealant that has split away and unsealed openings around new pipes and cables, across linear gaps at wall heads, cable penetrations and small duct penetrations where the tested detail allows.

Barn and farm-building conversions near places like Old Netley often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

When to call us in Old Netley
Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.
Most enquiries start with something like this:
- Hidden openings found during inspections
- Unsealed joints where partitions meet the slab
- Unsealed openings around new pipes and cables
- Seals that don’t match their tested detail
Refits at places like Hedge End Retail Park, 2 miles to the north of Old Netley, often reroute services through walls between units.

Our process
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Smaller jobs around Old Netley can be grouped with others nearby. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Warn occupants and staff about the work
- Tell us your opening times and when work is allowed
- Confirm the product named in the specification
Ask for a quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

How the job changes by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.

Questions we’re asked in Old Netley
Could you schedule work at a campus like Solent University for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Will you take on work at estates like Hedge End Retail Park, close to Old Netley?
Yes. We cover Old Netley and the area around it, including industrial estates, business parks and retail parks such as Hedge End Retail Park. A few photos and the unit address let us price the work.
Will fire-rated sealant work on every penetration?
No. A sealant’s evidence covers set services, gaps and wall or floor types. Outside that, a different product is needed.
Is your workmanship covered by a guarantee?
Yes. Our workmanship is backed for 12 months on every job.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Do you work in Scotland as well as England?
Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, with proprietary products tested for the end use.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Why it’s worth doing now in Old Netley
The longer openings stay, the more there tend to be: each new service adds to the list. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. One visit to deal with every failing joint makes more sense than several trips to a place like Old Netley. Send photographs of each area and we’ll quote for the lot.
Pricing service penetrations depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Doing it in-house
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
A short, simple internal joint is often within reach of a maintenance team. 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.
