About our fire stopping in Alfriston
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. The enquiries we see most involve builders’ foam or ordinary silicone in compartment walls and fire seals cut back for extra cables and never reinstated, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and service gaps in risers. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Alfriston it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Alfriston, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Leave it or put it right?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed. Halls, stores and units around places like Alfriston may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Fire stopping around Alfriston: points for this area
Approved Document B is the English guidance that covers fire stopping around 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. What we install is set by the specification, and it goes in to the tested detail. Alfriston has several hotels close by, all within 2 miles. 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.
In a hotel such as Dean's Place Hotel, which lies south of Alfriston, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Hospital estates such as Chailey Heritage Marine Hospital, 4.2 miles to the south-west of Alfriston, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Do you need fire stopping in Alfriston?
Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access typically bring them to light.
Site and facilities staff are often the first to spot these:
- Fire-stopping items raised at inspection or handover
- Fire stopping installed outside its tested range
- Builders’ foam or ordinary silicone in compartment walls
- Open linear gaps along the top of fire-resisting walls
Halls and meeting rooms at places like Church of St. Andrew sometimes gain new services, and any compartment wall crossed needs the specified seal.
What to look for in a quote
- The named product and why it was chosen
- How they’ll work around occupants
- Whether primer will be used where the manufacturer specifies it
- Proof of insurance
For managing agents and facilities managers
We work for building owners and managing agents on everything from one building to a spread of sites around Alfriston. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Alfriston need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send 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.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Tell us which areas need to stay in use
- Confirm the product named in the specification
- Warn occupants and staff about the work

Questions we are asked in Alfriston
Does your area include sites such as Berwick Court Farm Business Park, near Alfriston?
Yes. Estates, retail parks and business parks around Alfriston, Berwick Court Farm Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Would you work within a site like Chailey Heritage Marine Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How long does a job like this take?
That varies with the scale of the job, 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’ll set out a timescale with the quote.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Will you sign off the seals for us?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.
Is colour matching possible?
It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
