How we handle fire stopping in Netley Marsh
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 part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail. We work on linear gaps at wall heads, pipe penetrations and cable penetrations, and the failures we are asked to look at most are seals disturbed by maintenance and left open and unsealed penetrations discovered above suspended ceilings. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Netley Marsh, that means joint design, primers and backing rod as standard.
Around smaller places like Netley Marsh, 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.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Netley Marsh need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Move anything stored against the joints
- Have the specification and drawings to hand
- Point out any areas we must not close
Quotes
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Advice
Questions we are asked in Netley Marsh
Is Rushington Business Park, near Netley Marsh, within your area?
Yes. We cover Netley Marsh and the area around it, including industrial estates, business parks and retail parks such as Rushington Business Park. Photos and a short description are enough for a first look.
Would you work within a site like Tatchbury Mount Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What if there’s asbestos in the old mastic?
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.
Is the BS 476 change in 2029 relevant to fire stopping?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, subject to transitional arrangements. Scotland follows its own Technical Handbook.
Will you write the fire-stopping specification?
No, we don’t design fire stopping. Once you have a specification, we can price and install the sealant elements of it, and tell you if a detail needs another product.
Can you fire stop behind the services contractors?
Yes. Send the schedule or marked-up drawings and the specified product details. We can follow the services contractor floor by floor so areas aren’t left open.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Have penetrations checked while they can still be seen
- Don’t let anyone top up a fire seal with the wrong product
- Make fire stopping part of every scope that crosses a fire-resisting wall
- File the specified details where the next contractor can find them
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
Commercial clients in Netley Marsh
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.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Different surfaces, different methods
Risers and ceiling voids
Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically.
Drylining partitions
Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness before sealing.
Fire stopping in Netley Marsh: the local picture
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. There are nine care or nursing homes within about 2 miles of Netley Marsh. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
For a unit at a centre such as Totton Shopping Centre, 1.8 miles to the east of Netley Marsh, penetration seals are worth checking after each shop fit. On a site such as Rushington Business Park, which lies east of Netley Marsh, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Theatres, wards and plant rooms at sites like Tatchbury Mount Hospital, 1.1 miles to the north of Netley Marsh, all have compartment walls crossed by services.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Reviewing a building’s overall fire safety
- Openings that need collars, wraps, batts or boards rather than sealant
- Writing the fire-stopping specification
If in doubt, phone 01277 525 020 or email us and we’ll say what we think.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
