Fire stopping in Rochester Riverside, done properly
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. The enquiries we see most involve seals that don’t match their tested detail and service penetrations left open after M&E works, on pipe penetrations, linear gaps at wall heads and cable penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Rochester Riverside it comes down to the same thing: the right product in a properly prepared joint.
Around Rochester Riverside, penetration and linear seals tend to be one-building jobs. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Your questions answered
Can work at a site such as University for the Creative Arts - Rochester fit around teaching?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is hospital work, at somewhere like Medway Maritime Hospital, something you do?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
What do BS EN 1366-3 and BS EN 13501-2 mean?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months on every job.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you hold third-party fire-stopping installer certification?
No, and we’d rather be clear about that. Some clients require third-party installer schemes even though the law doesn’t, 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.
What we’re called out for in Rochester Riverside
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.
Look out for the following:
- Head-of-wall gaps with no fire seal
- Fire sealant pulled out of the opening
- Unsealed penetrations discovered above suspended ceilings
- Seals disturbed by maintenance and left open
For a site team at a college like MidKent College Gillingham Campus, which lies east of Rochester Riverside, fire-rated sealing is best scheduled after the summer works.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Plastic pipes whose detail calls for a collar or wrap
- Walls or floors that aren’t fire-resisting to begin with
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
Surfaces we seal
- Linear gaps at wall heads
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
Cost factors for service penetrations
Quotes vary with the job. It mainly depends on:
- How accessible the joints are
- Removal of failed or old sealant
- Which sealant the job calls for
- Induction, permit and paperwork requirements
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
What to include in your enquiry
However big the job, the same details help:
- Access details, including height
- What the building is and how it’s used
- Clear photographs of the problem areas
- Asbestos survey details if the building is older
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
From enquiry to sign-off
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For a site in Rochester Riverside, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.
- We read the specification, drawings or penetration schedule you send.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Flag any permit to work we’ll need
- Share the asbestos register for older buildings
- Point out any areas we must not close

Fire stopping in Rochester Riverside: the local picture
Two care or nursing homes sit less than 2 miles from Rochester Riverside. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. 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. What we install is set by the specification, and it goes in to the tested detail.
Hospital estates such as Medway Maritime Hospital (1.6 miles south-east of Rochester Riverside) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For an estates team at a campus like University for the Creative Arts - Rochester, 0.8 miles south-east of Rochester Riverside, summer M&E works are typically followed by a round of penetration sealing.
