How we handle fire stopping in Whitchurch-on-Thames
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. Most enquiries involve unsealed joints where partitions meet the slab and unsealed openings around new pipes and cables, on cable penetrations, service gaps in risers and linear gaps at wall heads. A specialist sealant contractor works differently from a general builder: on jobs in Whitchurch-on-Thames, preparation and product choice get the time they need.
Around smaller places like Whitchurch-on-Thames, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Our workmanship is guaranteed for 12 months, in Whitchurch-on-Thames as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Our process
At the end of each section, 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. Jobs in and around smaller places like Whitchurch-on-Thames are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Confirm the product named in the specification
- Explain the parking and delivery arrangements
- Make sure the joints can be reached

Common problems we fix in Whitchurch-on-Thames
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.
Things that usually lead to an enquiry:
- Seals disturbed by maintenance and left open
- Fire stopping installed outside its tested range
- Unsealed penetrations discovered above suspended ceilings
- Non-fire-rated filler around services
For a hospital such as Battle Hospital, which lies south-east of Whitchurch-on-Thames, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.
What to look for in a quote
- Health and safety accreditation such as CHAS
- Their public liability cover

Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Whitchurch-on-Thames can form part of a wider programme across Oxfordshire.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Check risers and ceiling voids after each round of works
- Foam or ordinary sealant is never a fire-seal repair
- Get seals inspected before ceilings and boxing close
- Ask the designer to confirm details early on refits
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
Leave it or put it right?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Halls, stores and units around places like Whitchurch-on-Thames may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Common questions from Whitchurch-on-Thames clients
What does the BS 476 change mean for fire-rated sealant in Whitchurch-on-Thames?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you seal around new services in a hotel near Whitchurch-on-Thames?
Yes, where the specification calls for fire-rated sealant. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Can the sealant be colour-matched?
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.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
When can you be on site?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork normally needs a different solution set by the designer and we flag that rather than guess.
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, along the full length of the run.
Compartment walls and floors in Whitchurch-on-Thames
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. What we install is set by the specification, and it goes in to the tested detail. The area within 2 miles of Whitchurch-on-Thames holds a number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Hotels like The Swan Hotel (0.5 miles south-west of Whitchurch-on-Thames) are refurbished in phases, and each phase can open up compartment walls. For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing.
