Work for main contractors and building owners
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
How we handle fire stopping in Ventnor
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. The enquiries we see most involve improvised or mixed-product fire seals and fire-rated sealant that has cracked or shrunk back, across service gaps in risers, linear gaps at wall heads and pipe penetrations. Whether you call it commercial sealant work, mastic application or joint sealing, in Ventnor it comes down to the same thing: the right product in a properly prepared joint.
Buildings in a smaller place such as Ventnor that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Service penetrations in Ventnor buildings
The area within 2 miles of Ventnor holds a good number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Hospital estates such as Arthur Webster Memorial Hospital for Children (to the north-east of Ventnor) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. On estates like Ventnor Industrial Estate, which lies north of Ventnor, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
Ventnor is about 8 miles south-east of Newport, in the Isle of Wight. Across the PO38 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Ventnor is one of 125 places in the Isle of Wight on our list for service penetrations. There’s a separate page for Portsmouth, roughly 16 miles from Ventnor.
Commercial sites across PO38 are covered. Buildings on Old Station Road, Market Street and High Street are within our area for service penetrations. Main routes into Ventnor include the A3055 and B3327, which helps when planning parking and deliveries for the job. If your building is just outside Ventnor, we cover Steephill (1 mile south-west), Bonchurch (1 mile east), St Lawrence (1 mile west), Wroxall (2 miles north) and Luccombe Village (2 miles north-east). A short drive away, we cover Newport (8 miles north-west), Ryde (9 miles north), Cowes (12 miles north), Sandown (5 miles north-east), Shanklin (3 miles north-east) and East Cowes (11 miles north). As one of the bigger centres in the Isle of Wight, Ventnor has a broad mix of commercial, public and industrial buildings. Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.
Around Ventnor
We work on buildings around St Francis Catholic and Church of England Primary Academy and The Blenheim pub, among other places. The nearest railway station is Shanklin station, roughly 3 miles north-east. Well-known places in the area include Arthur Webster Memorial Hospital for Children (3 miles north-east) and Longshoremans Museum (under half a mile south). Not far away are Alverstone Mead and St Boniface Down.
What happens if it’s left?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is typically a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. In a smaller place such as Ventnor, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

When to call us in Ventnor
Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access usually bring them to light.
These are often picked up first by site or facilities staff:
- Fire seals cut back for extra cables and never reinstated
- Unsealed penetrations discovered above suspended ceilings
- Old intumescent sealant that has split away
- Penetration schedules that need working through
Older community buildings such as St Catherine's Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
What your quote should include
- How the joint faces will be prepared and primed
- What level of public liability insurance do they hold?
- Which product they’ll use, and why it suits the joint
- Will RAMS and insurance details be available?
Ventnor: questions and answers
Do you seal service penetrations in hotels around Ventnor?
Yes, to the specification and the product’s tested detail. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we will tell you if the detail calls for a collar, wrap or batt instead.
Can you work on a hospital site such as Arthur Webster Memorial Hospital for Children?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do you work in Ventnor?
Yes. Ventnor falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or use the quote form.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
How the job changes by surface
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area, and note anything we find that isn’t on it.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we’ll say if that applies.

Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Have penetrations checked while they can still be seen
- Foam or ordinary sealant is never a fire-seal repair
- Keep product data and details in the fire safety file
- Ask the designer to confirm details early on refits
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.
From enquiry to sign-off
Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For a site in Ventnor, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.
