Fire stopping for commercial buildings in Terriers
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail, not a rule of thumb. If you’re dealing with unsealed openings around new pipes and cables and old intumescent sealant that has split away, we can help. Most enquiries from Terriers start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Around Terriers, penetration and linear seals tend to be one-building jobs. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Work in places the size of Terriers is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- 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.
Getting the site ready
- Tell staff and tenants when we will be in
- Let us know about inductions and permits
- Agree which areas must stay open

What sets the cost
Quotes vary with the job. It mainly depends on:
- Joint width, depth and condition
- Induction, permit and paperwork requirements
- Removal of failed or old sealant
- Which sealant the job calls for
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Sending details for a quote
To price the job accurately, we need to understand the site. Send us:
- Your programme or deadline
- Approximate linear metres or a joint schedule
- The postcode of the building
- Photos of the joints, close up and from further back
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Have penetrations checked while they can still be seen
- Treat an open penetration as a priority repair
- Ask which product is in place before decorating
- Record which product was used where
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and installation follows the programme.
How the job changes by surface
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance along with any permits your site needs.
Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Terriers. One quote can cover more than one site, which keeps the paperwork simple.

What else we do in Terriers
Where services cross fire walls in Terriers
A 2-mile radius around Terriers takes in 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. Central London is about 29 miles from Terriers. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.
For a unit at a centre such as Wycombe Retail Park, 1.7 miles south of Terriers, penetration seals are worth checking after each shop fit. In a hotel such as Red Lion Hotel, 1.1 miles south-west of Terriers, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Hospital estates such as Wycombe General Hospital (to the south-west of Terriers) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Terriers is about 1 mile north-east of High Wycombe, in Buckinghamshire. We send applicators to Terriers for service penetrations. Terriers is one of 308 places we cover in Buckinghamshire. We also cover Reading, some 17 miles away.

Common questions from Terriers clients
Is a smaller place like Terriers outside your area?
Not at all. Terriers is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is The Wye Industrial Estate, near Terriers, within your area?
Yes. Our area takes in Terriers and its surroundings, with estates and business parks such as The Wye Industrial Estate included. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can you fire stop behind the services contractors?
Yes, provided a specification covers them. New services after M&E works often breach existing seals and we close them with the specified product.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How long does a job like this take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Which standards are fire seals tested to?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. EI 60 means integrity and insulation for 60 minutes in the tested arrangement; installing to the detail is what carries that across to site.
What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Issuing fire ratings or certificates for seals
- Fire risk assessments, a job for a competent assessor
- Large openings beyond what any sealant detail covers
If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
What we seal
- Joints between fire-resisting walls and floors
