What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Fire risk assessments, a job for a competent assessor
- Issuing fire ratings or certificates for seals
- Plastic pipes whose detail calls for a collar or wrap

Fire stopping for commercial buildings in Southfields
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you’re dealing with improvised or mixed-product fire seals and openings left by services added after handover, we can help. A single leaking joint is often how a building in Southfields first comes to us: we look at the rest while we’re there and tell you what we find.
A job near Southfields is typically planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Signs you need fire stopping in Southfields
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.
Clients typically get in touch after noticing something like this:
- Fire-rated sealant that has cracked or shrunk back
- Penetration schedules that need working through
- Unsealed penetrations discovered above suspended ceilings
- Improvised or mixed-product fire seals
For a school such as Orsett Church of England Primary School, penetration sealing fits best at the end of the summer works.

Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
Surface by surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones typically call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range.
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Southfields can form part of a wider programme.
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Compartments and services around Southfields
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. Our part stays the same: the specified product, installed to its tested detail. Southfields has two care or nursing homes no more than 2 miles away. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. We install fire-rated sealant to the tested detail where it is specified.
For a site team at a college like USP College, 2.2 miles south-west of Southfields, fire-rated sealing is best scheduled after the summer works. Halls and meeting rooms at places like St Giles & All Saints Church sometimes gain new services, and any compartment wall crossed needs the specified seal.

On site: what to expect
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. If others near Southfields need work, visits can be combined. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- 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.
Before we start on site
- Flag any permit to work we will need
- Share your working hours and any access restrictions
- Let building users know which areas are affected

Questions we’re asked in Southfields
Could you schedule work at a campus like USP College for the vacation?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is Southfields off your patch?
Not at all. Southfields is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you design or specify fire stopping?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
What does an EI 60 rating mean?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. That rating only holds when the product is installed to its tested detail.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
