Fire stopping in Furzedown
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Fire stopping for commercial buildings in Furzedown
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. If you have penetration schedules that need working through and builders’ foam or ordinary silicone in compartment walls, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Furzedown, preparation and product choice get the time they need.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to bring in a specialist
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Penetration seals near Furzedown
A 2-mile radius around Furzedown takes in a number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. For England, the fire stopping of penetrations is dealt with in 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.
Large healthcare estates like St George's Hospital (1.2 miles west of Furzedown) change their services often, so penetration seals are worth checking after M&E work. At a university such as University of the Arts London, which lies north of Furzedown, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. In a retail centre such as Priory Retail Park, 1.5 miles south-west of Furzedown, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.
Furzedown is about 3 miles east of Wimbledon, in Greater London. We send applicators to Furzedown for service penetrations. Furzedown is one of 764 places we cover in Greater London for service penetrations. For work in that direction, see our London page.

Furzedown: questions and answers
Will you work in a care home in Furzedown without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we will work to them.
Can you take on a job at a hospital such as St George's Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How long does a typical visit take?
That varies with the scale of the job, but the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Is the work guaranteed?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Can you tell us what fire stopping our building needs?
No. The specification comes from your designer, fire engineer or building control. Our role is installing what they specify, to the product’s tested detail.
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Warn occupants and staff about the work
- Agree which areas must stay open
- Explain the parking and delivery arrangements

Advice
Why deal with it now?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. In Furzedown, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Maintenance after handover
Regular inspection catches problems early. Specifically:
- Keep product data and details in the fire safety file
- Include service cupboards in routine inspections
- Brief every trade that openings they make must be sealed
- Settle who seals which penetrations at the start of a project
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open.
Cost factors for service penetrations
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Whether the work must be split into stages
- Distance, for remote addresses
- How much existing material needs removing
- Backing rod, priming and other preparation
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- Anything awkward about access or site hours
- Clear photographs of the problem areas
- The site address and postcode
- Any dates the work must fit around
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email us.
Different surfaces, different methods
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any that don’t are flagged.
