Fire stopping in Newington
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Why it’s worth doing now in Newington
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Small buildings around Newington suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Fire stopping for commercial buildings in Newington
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. 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. The enquiries we see most involve unsealed penetrations discovered above suspended ceilings and unsealed openings around new pipes and cables, on service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors. Most enquiries from Newington start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
In places the size of Newington, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Where services cross fire walls in Newington
Central London is about 34 miles from Newington. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. 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 Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification. For a site team at a college like Sittingbourne College, 2.5 miles south-east of Newington, fire-rated sealing is best scheduled after the summer works. For a school such as Newington Church of England Primary School, penetration sealing fits best at the end of the summer works.

What the job involves on each surface
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement.
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.
Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Common questions from Newington clients
Is Newington off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you take on a job at a hospital such as Medway Maritime Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
What changes on 2 September 2029?
From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, with transitional arrangements set by the Government. The European route, BS EN 13501-2, then applies. Product selection stays with your designer.
Can weather delay the job?
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 the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
