About our fire stopping in Segensworth
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. We work on pipe penetrations, service gaps in risers and joints between fire-resisting walls and floors, and what we’re called in for most is openings left by services added after handover and fire sealant pulled out of the opening. Looking for mastic applicators who cover Segensworth? We have been sealing commercial buildings since 2005.
A job near Segensworth is usually planned around one visit, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or email us and we will arrange a return visit.

Common problems we fix in Segensworth
Openings in fire-resisting walls normally appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.
Things that normally lead to an enquiry:
- Expanding foam used as fire stopping
- Old intumescent sealant that has split away
- Openings left by services added after handover
- Unsealed penetrations discovered above suspended ceilings
For a building such as St John, new heating or data runs are the usual reason penetrations need sealing.

Leave it or put it right?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. Older rural buildings around Segensworth 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, how much old material needs removing and the access. Call for a fixed quote when you’re ready.

On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For work around Segensworth, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We start with your penetration schedule, drawings or specification.
- 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 so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Arrange parking or a loading space
- For older buildings, check the asbestos register before work
- Clear stock, furniture or equipment away from the joints

Related advice
Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Agree the fire-stopping specification before services go in
- Keep general-purpose fillers away from compartment walls
- Ask which product is in place before decorating
- Look above ceilings when tiles are lifted for other jobs
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
Questions about Segensworth
Does your area include sites such as Solent Business Park, near Segensworth?
Yes. Our area takes in Segensworth and its surroundings, with estates and business parks such as Solent Business Park included. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can you seal around new services in a hotel near Segensworth?
Yes, to the specification and the product’s tested detail. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you cover Segensworth?
Yes. Segensworth falls within our area, and you can phone 01277 525 020 or email drawings and photos to get started.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Fire stopping in Segensworth: the local picture
Central London is about 66 miles from Segensworth. Office refits around the commuter belt bring new cabling through fire-resisting walls. The area within 2 miles of Segensworth holds several hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.
Office fit-outs on sites such as Solent Business Park (to the north of Segensworth) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. At a healthcare site like Fareham Community Hospital, which lies west of Segensworth, new services through compartment walls are a constant, and each needs the specified seal.
Segensworth is about 3 miles north-west of Fareham, in Hampshire. Anywhere in PO15, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 723 places across Hampshire fall within our area, including Segensworth.

Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Plastic pipes whose detail calls for a collar or wrap
- Signing off or certifying a building’s fire stopping
If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think.
