Surface by 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 and the installation has to fit inside those limits.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.
How we handle fire stopping in Shinfield
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. If you are dealing with openings left by services added after handover and penetration schedules that need working through, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Shinfield from the first photos to the final walk-round, whether it’s one building or several.
Around smaller places like Shinfield, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Questions we are asked in Shinfield
Do you take on work at healthcare sites like Royal Berkshire Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Shinfield?
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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Can you work while the building is occupied?
Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep general-purpose fillers away from compartment walls
- Get seals inspected before ceilings and boxing close
- Ask which product is in place before decorating
- Ask the designer to confirm details early on refits
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
Fire stopping around Shinfield: points for this area
Approved Document B is the English guidance that covers fire stopping around 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. Shinfield lies roughly 37 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.
Wherever services are added at a hospital such as Royal Berkshire Hospital (to the north of Shinfield) the compartment line has to be made good with the specified product. Older community buildings such as Church of St Mary the Virgin that have been rewired or given new heating can have service gaps through walls worth checking against the specification. At a university such as University of Reading - Whiteknights Campus, which lies north of Shinfield, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Shinfield is about 3 miles south of Reading, in Wokingham. Businesses, contractors and managing agents in Shinfield use us for work on service penetrations. Our Wokingham coverage takes in 42 places, from busy centres to rural villages.
Anyone looking for fire stopping in RG2 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Teal Grove, Songbird Close and Skylark Way are within our area for service penetrations. Close to Shinfield, our area also takes in Ryeish Green (1 mile south-west), Whitley Wood (1 mile north-west), Three Mile Cross (1 mile west), Great Lea Common (1 mile west) and Arborfield (2 miles east). Bigger towns within reach include Wokingham (4 miles east), Woodley (4 miles north-east), Crowthorne (7 miles east), Winnersh (3 miles north-east), Arborfield Garrison (3 miles south-east) and Woosehill (4 miles east). Among the larger centres in Wokingham is Shinfield, and we take on service penetrations for its commercial and public buildings.

Should maintenance staff do it?
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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Building owners, agents and FMs in Shinfield
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Shinfield can form part of a wider programme.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

On site: what to expect
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Work in places the size of Shinfield is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Let building users know which areas are affected
- Tell us what induction or permit system the site runs
- Agree which areas must stay open

Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Large openings beyond what any sealant detail covers
- Approving the work on behalf of building control
- Construction that lacks the fire resistance the seal relies on
