About our fire stopping in Westcot
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and pipe penetrations, and the failures we’re asked to look at most are fire-rated sealant that has cracked or shrunk back and non-fire-rated filler around services. Most enquiries from Westcot start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a smaller site near Westcot, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Our workmanship is guaranteed for 12 months, in Westcot as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Compartments and services around Westcot
Westcot lies roughly 61 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
Schools such as The Ridgeway Church of England (C) Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. On a hospital site such as Faringdon Day Hospital, 5.8 miles to the north-west of Westcot, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Westcot is about 4 miles west of Wantage, in Oxfordshire. Any commercial site in Westcot is covered. 423 places across Oxfordshire fall within our area, Westcot among them. There’s a separate page for Oxford, roughly 16 miles from Westcot.

What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Fire doors, dampers or other fire safety equipment
- Deciding what a wall or floor needs, which belongs to the designer
- Issuing fire ratings or certificates for seals
Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly before you book.
Joints and surfaces we work on

- Small duct penetrations where the tested detail allows

Your questions answered
Can you work on a hospital site such as Faringdon Day Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What happens to BS 476 references for fire stopping in Westcot?
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.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Can you work while the building is occupied?
In the majority of cases, yes. We phase the work so most of the building stays in use.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking anything from one day to a planned run of visits, depending on the number of seals and the access. Jobs in and around smaller places like Westcot are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Preparing the site
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
- Make sure the joints can be reached

What we are called out for in Westcot
Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.
Typical triggers for a call:
- Fire sealant pulled out of the opening
- Fire seals cut back for extra cables and never reinstated
- Penetration schedules that need working through
- Improvised or mixed-product fire seals
Halls and meeting rooms at places like Church of the Holy Rood sometimes gain new services, and any compartment wall crossed needs the specified seal.

General trades versus a specialist
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.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Get seals inspected before ceilings and boxing close
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Flag new cables with no seal around them
- Keep general-purpose fillers away from compartment walls
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.
Leave it or put it right?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Halls, stores and units around places like Westcot may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
