Fire stopping for commercial buildings in Penton Corner
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. If you are dealing with openings left by services added after handover and old intumescent sealant that has split away, we can help, on cable penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Penton Corner is the same: the right product in a properly prepared joint.
Around smaller places like Penton Corner, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What we are called out for in Penton Corner
Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.
Look out for the following:
- Fire seals cut back for extra cables and never reinstated
- Snag lists that include open service penetrations
- Openings left by services added after handover
- Openings found when ceilings come down for a refit
Older community buildings such as Holy Trinity Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
What your quote should include
- Will CSCS-carded applicators be on site?
- Their plan for phasing and protecting the area
- What the guarantee covers, and for how long
- What level of public liability insurance do they hold?
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Brief every trade that openings they make must be sealed
- Keep product data and details in the fire safety file
- Check with the data sheet before painting over fire sealant
- Arrange inspection before areas are covered up
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.
What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Approving the work on behalf of building control
- Walls or floors that aren’t fire-resisting to begin with
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly.
Joints and surfaces we work on
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers

Owners, agents and contractors
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
How the job changes by surface
Small ducts
We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.
On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and we clear our waste as we work. For a building around Penton Corner, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We start with your penetration schedule, drawings or specification.
- 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 so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Tell staff and tenants when we will be in
- Tell us what induction or permit system the site runs
- Clear stock, furniture or equipment away from the joints

Questions about Penton Corner
Can you work in a care home near Penton Corner with residents in?
Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.
Could you schedule work at a campus like Andover College for the vacation?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you have third-party installer accreditation for fire stopping?
No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
