On site: what to expect
Working in a building that stays open takes some planning. 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. Jobs in and around smaller places like Loosley Row are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Warn occupants and staff about the work
- Explain the parking and delivery arrangements
- Tell us what induction or permit system the site runs

Fire stopping in Loosley Row
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. Site teams most often ask us about expanding foam used as fire stopping and openings left by services added after handover, across joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and linear gaps at wall heads. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Loosley Row, preparation and product choice get the time they need.
Rural conversions around Loosley Row can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Every job we finish is backed by a 12-month workmanship guarantee, in Loosley Row as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What the job involves on each surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range.
What happens if it’s left?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed. Converted and older buildings near places like Loosley Row tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

What else we do in Loosley Row
Fire stopping around Loosley Row: what changes locally
Fire stopping of openings and penetrations in England falls under Approved Document B. 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. We install whatever has been specified, to the product’s tested detail. At about 34 miles from central London, Loosley Row is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
Where a unit on an estate such as Crownfield Industrial Estate (0.7 miles south-west of Loosley Row), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. For a building such as Church of St John the Evangelist, new heating or data runs are the usual reason penetrations need sealing.
Loosley Row is about 6 miles north-west of High Wycombe, in Buckinghamshire. Across the HP27 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Across Buckinghamshire, 308 places are covered, Loosley Row among them. For work in that direction, see our Reading page (18 miles or so).
We cover the HP27 postcode districts for service penetrations. We cover commercial and managed buildings on Loosley Hill, Foundry Lane and Lower Road. If your building is just outside Loosley Row, we cover Lacey Green (1 mile east), Saunderton Lee (1 mile south-west), Saunderton (1 mile south), Rout's Green (2 miles south-west) and Bledlow Ridge (2 miles south-west). A short drive away, we cover Aylesbury (8 miles north), High Wycombe (6 miles south-east), Chesham (9 miles east), Marlow (9 miles south), Amersham (10 miles east) and Beaconsfield (10 miles south-east).

When to call us in Loosley Row
Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.
Common reasons buildings call us in:
- Seals that don’t match their tested detail
- Service penetrations left open after M&E works
- Fire-rated sealant that has cracked or shrunk back
- Builders’ foam or ordinary silicone in compartment walls
Schools such as St John's Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Issuing fire ratings or certificates for seals
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Walls or floors that aren’t fire-resisting to begin with
If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Cable penetrations
- Small duct penetrations where the tested detail allows
Looking after the joints
Regular inspection catches problems early. Specifically:
- Foam or ordinary sealant is never a fire-seal repair
- Look above ceilings when tiles are lifted for other jobs
- Have penetrations checked while they can still be seen
- Keep product data and details in the fire safety file
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there, not months later.
Your questions answered
Can you work at a site such as Crownfield Industrial Estate, by Loosley Row?
Yes. Estates, retail parks and business parks around Loosley Row, Crownfield Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Loosley Row?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
