Commercial clients in West Thorney
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around West Thorney. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Fire stopping in West Thorney
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. If you are dealing with unsealed openings around new pipes and cables and seals that don’t match their tested detail, we can help. Looking for mastic applicators who cover West Thorney? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Rural conversions around West Thorney can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
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.

When to call us in West Thorney
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 typically bring them to light.
Site and facilities staff are often the first to spot these:
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed openings around new pipes and cables
- Unsealed penetrations discovered above suspended ceilings
- Penetration schedules that need working through
Hospital estates such as Havant War Memorial Hospital (4.3 miles north-west of West Thorney) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Report damaged or disturbed seals as soon as they’re spotted
- Put resealing into every M&E and fit-out package
- Include service cupboards in routine inspections
- Keep general-purpose fillers away from compartment walls
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.
Where services cross fire walls in West Thorney
West Thorney lies roughly 59 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
On estates like Finchwood Farm Industrial Estate (2.5 miles west of West Thorney), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Holiday works at schools like Thorney Island Community Primary School often leave service openings to seal before pupils return.

How the job changes by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point so we know it sits within the tested range, and any that don’t are flagged.
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Smaller jobs around West Thorney can be grouped with others nearby. A fixed quote is given before anything starts.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- 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.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready

What else we do in West Thorney
What happens if it’s left?
Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. For buildings around smaller places like West Thorney, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Why us?
- Health and safety: CHAS accredited
- One phone line for London, the South East and Scotland
- Clear, fixed quotes
- Constructionline member for supplier checks

Common questions from West Thorney clients
Is a hospital such as Havant War Memorial Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Is a smaller place like West Thorney outside your area?
Not at all. West Thorney is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Can you reseal penetrations after our M&E works?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see.
What changes on 2 September 2029?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, though transitional rules apply. Scotland follows its own Technical Handbook, including clause 2.1.14 on service penetrations.
Do you design or specify fire stopping?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
Will fire-rated sealant work on every penetration?
No. It depends on the tested detail for that wall or floor and service. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we will tell you when that applies.
