When to call us in West End
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.
Clients usually get in touch after noticing something like this:
- Fire-stopping items raised at inspection or handover
- Hidden openings found during inspections
- Seals that don’t match their tested detail
- Fire sealant pulled out of the opening
On estates like Seddul Bahr Industrial Estate, which lies north-east of West End, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Fire stopping for commercial buildings in West End
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in West End. If you’re dealing with fire stopping installed outside its tested range and seals disturbed by maintenance and left open, we can help, whatever the surface. Most enquiries from West End start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Converted and extended buildings around places like West End can mix old and new construction, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Other services in West End
West End: questions and answers
Can you work around term dates at a campus such as University of Southampton?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you seal penetrations in a hotel in West End after a refit?
Yes, where fire-rated sealant is the specified product. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member.
Why deal with it now?
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these, and the other benefits follow. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Fire-rated sealing for West End buildings
West End has several hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. West End has five care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
Residences at universities like University of Southampton (2.7 miles west of West End) have compartment walls that must be resealed whenever services change. For a building such as Church of St James, new heating or data runs are the usual reason penetrations need sealing.
West End is about 2 miles east of Southampton, in Hampshire. Businesses, contractors and managing agents in West End can call on us for service penetrations. West End is one of 723 places in Hampshire on our list for service penetrations.

Different surfaces, different methods
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance along with any permits your site needs.
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, with no gaps along the run.
Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Treat an open penetration as a priority repair
- Arrange inspection before areas are covered up
- File the specified details where the next contractor can find them
- Brief every trade that openings they make must be sealed
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.
From enquiry to sign-off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. If neighbouring businesses or buildings around West End need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- We read the specification, drawings or penetration schedule you send.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use
