Fire-rated sealing for Hersham buildings
Hersham is about 16 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. Hersham has a number of hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.
On a hospital site such as Walton Community Hospital, which lies north of Hersham, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. At a college such as Brooklands Technical College - Weybridge Campus, 2.7 miles west of Hersham, checking penetration seals after summer M&E works is good practice.

About our fire stopping in Hersham
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Hersham. We work on service gaps in risers, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and what we are called in for most is seals disturbed by maintenance and left open and penetration schedules that need working through. One point of contact handles commercial sealant work in Hersham from the first photos to the final walk-round, whether it’s one building or several.
Converted and extended buildings around places like Hersham can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.
Work we carry out in Surrey comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email the details over and we’ll come back to it.

Signs you need fire stopping in Hersham
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
These are often picked up first by site or facilities staff:
- Old intumescent sealant that has split away
- Fire stopping installed outside its tested range
- Hidden openings found during inspections
- Seals disturbed by maintenance and left open
Tenant changes at parks like Hersham Place Technology Park, under half a mile to the south-east of Hersham, bring new data and services, and openings through fire-resisting walls need the specified seal.

Why deal with it now?
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Work in places the size of Hersham is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- 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 first.
- 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
- Clear stock, furniture or equipment away from the joints
- Let building users know which areas are affected
- Have the specification and drawings to hand

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Check risers and ceiling voids after each round of works
- Check with the data sheet before painting over fire sealant
- Flag new cables with no seal around them
- Foam or ordinary sealant is never a fire-seal repair
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.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.
Commercial clients in Hersham
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Questions about Hersham
How does the move away from BS 476 affect penetration seals in Hersham?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Can work at a site such as Kingston University Penrhyn Road Campus fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Can the building stay open while you work?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Is your workmanship covered by a guarantee?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
Different surfaces, different methods
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance along with any permits your site needs.
