Fire stopping near Chilbolton
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Surface by surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.
Fire stopping for commercial buildings in Chilbolton
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 buildings around Chilbolton. We work on cable penetrations, linear gaps at wall heads and service gaps in risers, and the failures we are asked to look at most are head-of-wall gaps with no fire seal and seals disturbed by maintenance and left open. One point of contact handles commercial sealant work in Chilbolton from the first photographs to the final walk-round, whether it’s one building or several.
A job near Chilbolton is normally planned around one visit, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

What sets the cost
We price every job individually. The things that drive the figure:
- The product specified
- The total length or number of joints
- The site’s rules and procedures
- Working within restricted access windows
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- Drawings or a marked-up plan, if available
- Asbestos survey details if the building is older
- What the building is and how it’s used
- Any specification or named product
For a fixed quote, call the office on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. Our quote form is another easy route.
Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Large openings beyond what any sealant detail covers
- Construction that lacks the fire resistance the seal relies on
- Writing the fire-stopping specification
If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think before you book.
What we seal
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Service gaps in risers
What happens if it’s left?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is usually a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Halls, stores and units around places like Chilbolton may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Pricing service penetrations depends on quantities, condition and access. Ask us for a fixed quote.

How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. Rural sites near Chilbolton may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Point out any areas we must not close
- Send your site hours and access windows
- Warn occupants and staff about the work
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Questions we’re asked in Chilbolton
Is a hospital such as Andover War Memorial Hospital somewhere you can work?
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.
Does your area include sites such as Harewood Forest Industrial Estate, near Chilbolton?
Yes. Estates, retail parks and business parks around Chilbolton, Harewood Forest Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.
Can the sealant be colour-matched?
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.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Is the BS 476 change in 2029 relevant to fire stopping?
From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, with transitional arrangements set by the Government. After that, the European classification under BS EN 13501-2 is the route. Product selection stays with your designer.
Can you handle several sites?
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 do I request a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Fire stopping in Chilbolton: the local picture
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. Our part stays the same: the specified product, installed to its tested detail. Central London is about 63 miles from Chilbolton. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
Halls and meeting rooms at places like Church of St Mary the Less sometimes gain new services, and any compartment wall crossed needs the specified seal. Theatres, wards and plant rooms at sites like Andover War Memorial Hospital (to the north-west of Chilbolton) all have compartment walls crossed by services. Industrial units on estates such as Harewood Forest Industrial Estate (2.6 miles north-east of Chilbolton) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
