How we handle fire stopping in Worlds End
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, call 01277 525 020 or email the details over with the schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. If you have fire sealant pulled out of the opening and expanding foam used as fire stopping, we can help, on joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads alike. Most enquiries from Worlds End start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
A job near Worlds End is normally planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
Every job we finish is backed by a 12-month workmanship guarantee, in Worlds End as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Service penetrations in Worlds End buildings
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Worlds End is about 60 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
Large healthcare estates like Queen Alexandra Hospital (3.8 miles south-east of Worlds End) change their services often, so penetration seals are worth checking after M&E work. Office fit-outs on sites such as Parklands Business Park, 1.6 miles east of Worlds End, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.
Worlds End is about 3 miles west of Waterlooville, in Hampshire. We cover Worlds End and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else.

Common questions from Worlds End clients
Is Worlds End too small for you to travel to?
Not at all. Worlds End is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Does your area include sites such as Parklands Business Park, near Worlds End?
Yes. Our area takes in Worlds End and its surroundings, with estates and business parks such as Parklands Business Park included. Photos and a short description are enough for a first look.
Do you approve fire stopping for building control?
No. Sign-off belongs to the designer or building control, not the installer. We will confirm the products and details used.
Can you reseal penetrations after our M&E works?
Yes. Share the penetration schedule and product details and a fixed quote follows. We can follow the services contractor floor by floor.
Is BS 476 being phased out?
In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029, subject to the Government’s transitional arrangements. After that, the European classification under BS EN 13501-2 is the route. Product selection stays with your designer.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Why it’s worth doing now in Worlds End
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. For buildings around smaller places like Worlds End, 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. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Looking after the joints
After handover, a little attention goes a long way:
- Look above ceilings when tiles are lifted for other jobs
- Ask the designer to confirm details early on refits
- Check with the data sheet before painting over fire sealant
- Keep general-purpose fillers away from compartment walls
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
How the quote is worked out
These are the things that shape the price:
- Which sealant the job calls for
- Induction, permit and paperwork requirements
- Backing rod, priming and other preparation
- How accessible the joints are
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Details that help us quote
Whether it’s one area or a whole building, these details speed things up:
- Approximate linear metres or a joint schedule
- When you need the work done
- The postcode of the building
- How the joints are reached, and at what height

Surface by surface
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we will say if that applies.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.
Our process
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Worlds End are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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
- For older buildings, check the asbestos register before work
- Move anything stored against the joints
- Send any specification or drawings in advance
Quotes
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
