Fire stopping for commercial buildings in Stonor
Facilities managers in Stonor often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. If you are dealing with snag lists that include open service penetrations and unsealed penetrations discovered above suspended ceilings, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Stonor, that means joint design, primers and backing rod as standard.
Smaller places such as Stonor still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Where services cross fire walls in Stonor
In England, Approved Document B covers fire stopping of openings and penetrations. 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 37 miles from Stonor. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.
Buildings near Stonor get the fire-rated product that’s specified, installed to its tested detail.

Work for main contractors and building owners
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
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, and each stage is agreed with your contact.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for.

Signs you need fire stopping in Stonor
Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.
It’s worth sending us details if you spot any of the following:
- Builders’ foam or ordinary silicone in compartment walls
- Fire-rated sealant that has cracked or shrunk back
- Openings left by services added after handover
- Improvised or mixed-product fire seals
Older community buildings such as Pishill Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
What to look for in a quote
- Whether their applicators hold CSCS cards
- How the existing material will be dealt with
- Can the work be phased to keep areas open?
- Do they follow the manufacturer’s priming guidance?
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Record which product was used where
- Keep general-purpose fillers away from compartment walls
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Include service cupboards in routine inspections
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.

Why it’s worth doing now in Stonor
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. One visit to deal with every failing joint makes more sense than several trips to a place like Stonor, rather than one at a time. Photos of every joint help us quote for the whole job.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Common questions from Stonor clients
What does the BS 476 change mean for fire-rated sealant in Stonor?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Do you design the fire stopping for buildings in Stonor?
No, that sits with the designer, fire engineer or building control. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Can you fit around our working hours?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
