Service penetrations in Dunsden Green buildings
At about 36 miles from central London, Dunsden Green is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. A 2-mile radius around Dunsden Green takes in several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
Workshops and IT rooms at colleges like The Chiltern College (1.7 miles south-west of Dunsden Green) are re-serviced often, leaving penetrations to seal. In a hotel such as The Great House Hotel, 1.5 miles to the south-east of Dunsden Green, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. On a site such as Suttons Business Park, which lies south of Dunsden Green, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

Fire stopping for commercial buildings in Dunsden Green
Facilities managers in Dunsden Green often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. Site teams most often ask us about fire sealant pulled out of the opening and service penetrations left open after M&E works, on cable penetrations, service gaps in risers and linear gaps at wall heads. Most enquiries from Dunsden Green start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Smaller places such as Dunsden Green still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Common questions from Dunsden Green clients
What does the BS 476 change mean for fire-rated sealant in Dunsden Green?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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.
Will you take on work at estates like Suttons Business Park, close to Dunsden Green?
Yes. We cover Dunsden Green and the area around it, including industrial estates, business parks and retail parks such as Suttons Business Park. Photos and a short description are enough for a first look.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
Do you work in Dunsden Green?
Yes. Dunsden Green falls within our area, and you can call the office on 01277 525 020 or email us to get started.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.
For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.
Quoting for work in Dunsden Green
Before we quote, we look at:
- The product specified
- Access and working height
- Joint width, depth and condition
- Removal of failed or old sealant
A quote for service penetrations depends on quantities, condition and access. Ask us for a fixed quote.
What to include in your enquiry
Whether it’s one area or a whole building, these details speed things up:
- Photos of the joints, close up and from further back
- What the building is and how it’s used
- The product your specification calls for
- Approximate linear metres or a joint schedule
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or email drawings and photos.
Leave it or put it right?
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product. Around Dunsden Green, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Approving the work on behalf of building control
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Construction that lacks the fire resistance the seal relies on
If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think.
Surfaces we seal
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Linear gaps at wall heads
What the job involves on each surface
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables and we work within those limits.
On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Dunsden Green can be grouped with others nearby. A fixed quote is given before anything starts.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Share the asbestos register for older buildings
- Flag any permit to work we will need
- Warn occupants and staff about the work
