Fire stopping for commercial buildings in Walliswood
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. 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. We work on service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are unsealed penetrations discovered above suspended ceilings and penetration schedules that need working through. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Walliswood, that means joint design, primers and backing rod as standard.
Around smaller places like Walliswood, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common problems we fix in Walliswood
A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position and has to be removed.
It’s worth sending us details if you spot any of the following:
- Damaged fire seals in risers and voids
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed penetrations discovered above suspended ceilings
- Snag lists that include open service penetrations
For a building at a site such as Northlands Business Park, which lies south-east of Walliswood, a check of penetration seals after each fit-out is good practice.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- Will CSCS-carded applicators be on site?
- Whether old or failed sealant will be cut out, not overlaid
- How the joint faces will be prepared and primed
Why act early in Walliswood
Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable. For buildings around smaller places like Walliswood, 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.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Why us?
- Commercial sealant work since 2005
- Public liability insurance in place
- Products installed to the manufacturer’s instructions
- One phone line for London, the South East and Scotland

How the job changes by surface
Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork normally needs a different solution set by the designer and we flag that rather than guess.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance along with any permits your site needs.
Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Deciding what a wall or floor needs, which belongs to the designer
- Issuing fire ratings or certificates for seals
- Walls or floors that aren’t fire-resisting to begin with
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

What sets the cost

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
What we need to price the job
We can often quote from photographs and a few details. Please tell us:

Questions about Walliswood
Can you work on a hospital site such as Horsham Hospital?
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.
Can you work at a site such as Northlands Business Park, by Walliswood?
Yes. Our area takes in Walliswood and its surroundings, with estates and business parks such as Northlands Business Park included. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
Is colour matching possible?
It depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Do the same rules apply to fire stopping in Scotland?
Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.
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’ll confirm with the quote.
Do you design or specify fire stopping?
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.
Fire stopping around Walliswood: how the place shapes the job
Central London is about 29 miles from Walliswood. Office refits around the commuter belt bring new cabling through fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
For a hospital such as Horsham Hospital, 5.5 miles south-east of Walliswood, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. Halls and meeting rooms at places like Church of St John the Baptist sometimes gain new services, and any compartment wall crossed needs the specified seal.
