How a job runs
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near West End may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
What we need from you
- Flag any permit to work we’ll need
- Point out any areas we must not close
- Clear stock, furniture or equipment away from the joints

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Fire stopping in West End, done properly
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around West End. If you’re dealing with fire seals cut back for extra cables and never reinstated and head-of-wall gaps with no fire seal, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in West End tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural conversions around West End 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.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Compartment walls and floors in West End
Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 18 miles from West End. Office refits around the commuter belt bring new cabling through fire-resisting walls.
At a university such as University of Hertfordshire (under half a mile north-west of West End), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a hospital such as Queen Elizabeth II Hospital, which lies north-west of West End, penetration sealing is normally phased ward by ward, with infection-control rules agreed first. Holiday works at schools like Essendon CofE (VC) Primary School often leave service openings to seal before pupils return.

How the quote is worked out
To price the job, we consider:
- Whether the work must be split into stages
- Travel to remote or island sites
- How much existing material needs removing
- The size and state of each joint
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- Anything awkward about access or site hours
- Where the site is, with the postcode
- Photos of the joints, close up and from further back
- Your programme or deadline
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email us.

Questions about West End
Is Birchwood Industrial Estate, near West End, within your area?
Yes. Our area takes in West End and its surroundings, with estates and business parks such as Birchwood Industrial Estate included. Photos and a short description are enough for a first look.
Is West End too far out for you?
No. Places such as West End are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
Do you hold third-party fire-stopping installer certification?
No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. Where a client or main contractor requires a scheme member, we’ll say so straight away rather than waste your time.
What will the job cost?
We don’t publish prices, because every site is different. Send photos or drawings and we will price it at a fixed figure.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Arrange inspection before areas are covered up
- Check with the data sheet before painting over fire sealant
- Report damaged or disturbed seals as soon as they’re spotted
- Don’t let anyone top up a fire seal with the wrong product
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.
When to bring in a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For managing agents and facilities managers
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’ll confirm with the quote.
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
What happens if it’s left?
The longer openings stay, the more there tend to be: each new service adds to the list. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Halls, stores and units around places like West End may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
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.
