Common questions from New Alresford clients
How does the move away from BS 476 affect penetration seals in New Alresford?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Do you work on fire-rated sealing in hotels in New Alresford?
Yes, to the specification and the product’s tested detail. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Is New Alresford in your area?
Yes. We cover New Alresford. To discuss a job, speak to us on 01277 525 020 or email a schedule or drawings.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
About our fire stopping in New Alresford
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. Site teams most often ask us about seals disturbed by maintenance and left open and fire stopping installed outside its tested range, on pipe penetrations, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows. One point of contact handles commercial sealant work in New Alresford from the first photographs to the final walk-round, whether it’s one building or several.
Buildings in a smaller place such as New Alresford that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

How the job changes by surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter and we work within those limits.
Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork normally needs a different solution set by the designer.
What happens if it’s left?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Settle who seals which penetrations at the start of a project
- Flag new cables with no seal around them
- Check with the data sheet before painting over fire sealant
- Include service cupboards in routine inspections
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. Work in places the size of New Alresford is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.

Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Fire stopping around New Alresford: points for this area
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. New Alresford lies roughly 54 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
For a building such as Church of St John the Baptist, new heating or data runs are the usual reason penetrations need sealing. Hotels like The Swan Hotel (to the north-east of New Alresford) are refurbished in phases, and each phase can open up compartment walls. In a school such as Sun Hill Junior School, fire-rated sealant goes in around service penetrations where it is specified.
