How we handle fire stopping in Cold Ash
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance. We work on linear gaps at wall heads, pipe penetrations and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are seals disturbed by maintenance and left open and unsealed penetrations discovered above suspended ceilings. A single leaking joint is often how a building in Cold Ash first comes to us: 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 Cold Ash, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Why deal with it now?
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. For buildings around smaller places like Cold Ash, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Put resealing into every M&E and fit-out package
- Foam or ordinary sealant is never a fire-seal repair
- Keep product data and details in the fire safety file
- Report damaged or disturbed seals as soon as they’re spotted
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
Fire-rated sealing for Cold Ash buildings
At about 51 miles from central London, Cold Ash is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. In England, Approved Document B covers fire stopping of 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. We install whatever has been specified, to the product’s tested detail.
At a healthcare site like West Berkshire Community Hospital (1.8 miles south-west of Cold Ash), new services through compartment walls are a constant, and each needs the specified seal. Hotels such as Regency Park Hotel, 0.8 miles south of Cold Ash, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Industrial units on estates such as Red Shute Hill Industrial Estate, 1.4 miles to the north-west of Cold Ash, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Other services in Cold Ash
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Common questions from Cold Ash clients
Is hospital work, at somewhere like West Berkshire Community Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What happens to BS 476 references for fire stopping in Cold Ash?
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.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
What do you charge?
Every job gets its own fixed quote. For yours, call 01277 525 020 or email the details over with a description of the work.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

- The size and state of each joint
- Whether old sealant has to be cut out first
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
