Fire stopping in Nash Street
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Fire stopping in Nash Street, done properly
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you have seals disturbed by maintenance and left open and service penetrations left open after M&E works, we can put it right, on pipe penetrations, small duct penetrations where the tested detail allows and service gaps in risers alike. Whoever orders the work in Nash Street, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural conversions around Nash Street 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.
A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or email a schedule or drawings and we’ll come back to it.

After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Check with the data sheet before painting over fire sealant
- Keep product data and details in the fire safety file
- Put resealing into every M&E and fit-out package
- Flag new cables with no seal around them
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open.

What else we do in Nash Street
Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Service penetrations in Nash Street buildings
Central London is about 21 miles from Nash Street. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
At a university such as University of Greenwich, 4.9 miles north-west of Nash Street, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. On a hospital site such as Gravesham Community Hospital (3.2 miles north of Nash Street), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Where a unit on an estate such as Bowes Industrial Centre (2.5 miles south of Nash Street), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
Nash Street is about 3 miles south of Gravesend, in Kent. We cover commercial sites throughout Nash Street, whether it’s a single job or part of a planned programme. Nash Street is one of 931 places we cover in Kent for service penetrations. For work in that direction, see our London page.

Close to Nash Street, our area also takes in Round Street (1 mile east), Longfield Hill (1 mile south-west), Meopham (1 mile south), Sole Street (1 mile south-east) and New Barn (1 mile west). Further afield, our area takes in Maidstone (12 miles south-east), Dartford (7 miles north-west), Sevenoaks (11 miles south-west), Gravesend (3 miles north), Tonbridge (14 miles south) and Northfleet (3 miles north).

Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. If others near Nash Street need work, visits can be combined. You’ll have a fixed quote before work starts.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready

Common questions from Nash Street clients
Does your area include sites such as Bowes Industrial Centre, near Nash Street?
Yes. We cover Nash Street and the area around it, including industrial estates, business parks and retail parks such as Bowes Industrial Centre. A few photos and the unit address let us price the work.
Is a smaller place like Nash Street outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Is BS 476 being phased out?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, though transitional rules apply. Scotland follows its own Technical Handbook.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Leave it or put it right?
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Around Nash Street, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

For managing agents and facilities managers
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Fire risk assessments, a job for a competent assessor
- Walls or floors that aren’t fire-resisting to begin with
- Plastic pipes whose detail calls for a collar or wrap
If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think before you book.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Pipe penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
