Fire stopping in Adstock
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How a job runs
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Adstock need work, visits can be combined. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Warn occupants and staff about the work
- Tell us what induction or permit system the site runs
- Share the asbestos register for older buildings
Getting a fixed quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email the details over.
Advice
About our fire stopping in Adstock
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. 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 unsealed openings around new pipes and cables and fire-rated sealant that has cracked or shrunk back. A specialist sealant contractor works differently from a general builder: in Adstock, that means joint design, primers and backing rod as standard.
Rural conversions around Adstock can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Maintenance after handover
For the best life from the joints:
- Report damaged or disturbed seals as soon as they’re spotted
- Keep product data and details in the fire safety file
- Keep general-purpose fillers away from compartment walls
- Check with the data sheet before painting over fire sealant
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.
What affects the price in Adstock
Your fixed quote is built from the real scope. It takes account of:
- Joint width, depth and condition
- The product specified
- Working within restricted access windows
- How accessible the joints are
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- When you need the work done
- The site address and postcode
- How the joints are reached, and at what height
- Approximate linear metres or a joint schedule
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Why deal with it now?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed. Halls, stores and units around places like Adstock may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Compartments and services around Adstock
In England, Approved Document B covers fire stopping of 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. Adstock is about 48 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal.
For a hospital such as Buckingham Community Hospital, 3.5 miles to the north-west of Adstock, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. At a university such as University of Buckingham (3 miles north-west of Adstock), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Adstock is about 3 miles south-east of Buckingham, in Buckinghamshire. Commercial clients in Adstock use us for work on service penetrations, as part of our coverage of Buckinghamshire. We work across 308 places in Buckinghamshire, large and small. Oxford is covered too, some 20 miles away.

Signs you need fire stopping in Adstock
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
If one of these sounds familiar, it’s time for a closer look:
- Openings found when ceilings come down for a refit
- Seals that don’t match their tested detail
- Openings left by services added after handover
- Non-fire-rated filler around services
Halls and meeting rooms at places like Church of St Cecilia sometimes gain new services, and any compartment wall crossed needs the specified seal.

Your questions answered
Will you plan work around the academic year at somewhere like University of Buckingham?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Adstock off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
