About our fire stopping in Clement Street
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. The enquiries we see most involve openings found when ceilings come down for a refit and head-of-wall gaps with no fire seal, on pipe penetrations, linear gaps at wall heads and service gaps in risers. One point of contact handles commercial sealant work in Clement Street from the first photos to the final walk-round, for single jobs and planned programmes alike.
Barn and farm-building conversions near places like Clement Street often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Every job we finish is backed by a 12-month workmanship guarantee, in Clement Street as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Fire stopping in Clement Street: the local picture
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 Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Clement Street is about 14 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
Workshops and IT rooms at colleges like North Kent College (1.4 miles north of Clement Street) are re-serviced often, leaving penetrations to seal. Hotels like Rowhill Grange Hotel & Utopia Spa, 1 mile to the west of Clement Street, are refurbished in phases, and each phase can open up compartment walls.

What we can’t put right
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Plastic pipes whose detail calls for a collar or wrap
- Approving the work on behalf of building control
- Construction that lacks the fire resistance the seal relies on
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
Joints and surfaces we work on
- Cable penetrations
- Linear gaps at wall heads

- Joints between fire-resisting walls and floors
- Pipe penetrations
- Service gaps in risers
Common problems we fix in Clement Street
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
Most enquiries start with one or more of the following:
- Openings left by services added after handover
- Fire stopping installed outside its tested range
- Fire-rated sealant that has cracked or shrunk back
- Hidden openings found during inspections
On a hospital site such as Darent Valley Hospital, 2.5 miles north-east of Clement Street, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
What your quote should include
- Which product they’ll use, and why it suits the joint

- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether their applicators hold CSCS cards
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.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
FAQs: Clement Street
Can work at a site such as University of Greenwich fit around teaching?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Clement Street 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.
Do you approve fire stopping for building control?
No. Approval sits with the designer, principal designer or building control. We will confirm the product and detail installed and agree any further records when we quote.
Does the weather affect the work?
It can, when the joints are outside. 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.
Can you reseal penetrations after our M&E works?
Yes. Share the penetration schedule and product details and a fixed quote follows. We can follow the services contractor floor by floor keeping pace with the programme.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Are you fully insured?
Yes. We’re fully insured, including public liability cover.
After the work
After handover, a little attention goes a long way:
- Don’t let anyone top up a fire seal with the wrong product
- Include service cupboards in routine inspections
- Report damaged or disturbed seals as soon as they’re spotted
- Check with the data sheet before painting over fire sealant
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For work around Clement Street, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Confirm the product named in the specification
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints
