Your questions answered
What happens to BS 476 references for fire stopping in Pirton?
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.
Is Pirton off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
What will the job cost?
Every job gets its own fixed quote. For yours, call 01277 525 020 or email the details over.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
What sets the cost
These are the things that shape the price:
- How much there is to seal
- How accessible the joints are
- Whether the work must be split into stages
- Location, for remote and island sites
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
What to include in your enquiry
However big the job, the same details help:
- Any specification or named product
- Anything awkward about access or site hours
- Drawings or a marked-up plan, if available
- The postcode of the building
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or email drawings and photos.

Service penetrations in Pirton buildings
In England, Approved Document B covers fire stopping of openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail. Central London is about 34 miles from Pirton. 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.
Where a unit on an estate such as Henlow Industrial Estate, which lies north-east of Pirton, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Hospital estates such as Fairfield Hospital, 4.2 miles to the north-east of Pirton, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For a building such as Church of St Mary (Church of England), new heating or data runs are the usual reason penetrations need sealing.
Pirton is about 3 miles north-west of Hitchin, in Hertfordshire. We send applicators to Pirton for service penetrations. Across Hertfordshire, 371 places are covered, including Pirton. London is covered too, some 34 miles away.
Commercial sites across SG5 are covered for service penetrations. Streets here include High Street, Crab Tree Lane and St Mary's Close, and sites on any of them can send details for a fixed quote. Nearby places we also cover include Holwell (2 miles north-east), Pegsdon (2 miles south-west), Apsley End (2 miles north-west), Shillington (2 miles north-west) and Hanscombe End (2 miles north-west) for service penetrations. A short drive away, we cover Stevenage (8 miles south-east), St Albans (15 miles south), Welwyn Garden City (13 miles south-east), Harpenden (11 miles south), Hitchin (3 miles south-east) and Hatfield (15 miles south).

Why act early in Pirton
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed. Around Pirton, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
What you get with us
- Failed material removed, not covered up
- Sealing commercial buildings since 2005
- Work carried out by CSCS-carded applicators
- Constructionline member for supplier checks

Honest limits
Before quoting, we check that sealant is the right answer. It won’t put right:
- Fire risk assessments, a job for a competent assessor
- Construction that lacks the fire resistance the seal relies on
- Designing or specifying fire stopping, which sits with the designer or fire engineer
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.
Surfaces we seal
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Ask the designer to confirm details early on refits
- Keep general-purpose fillers away from compartment walls
- Look above ceilings when tiles are lifted for other jobs
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
