About our fire stopping in Avery Hill
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on linear gaps at wall heads, service gaps in risers and pipe penetrations, and the usual reasons a site gets in touch are unsealed joints where partitions meet the slab and damaged fire seals in risers and voids. For commercial sealant work in Avery Hill, you deal with one contact from quote to sign-off, whether it’s one building or several.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, phone 01277 525 020 or send details through our quote form and we will come back to it.

Where services cross fire walls in Avery Hill
Nine care or nursing homes sit less than 2 miles from Avery Hill. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.
At a university such as University of Greenwich - Avery Hill, under half a mile to the south of Avery Hill, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. At a healthcare site like Eltham Community Hospital (1 mile west of Avery Hill), new services through compartment walls are a constant, and each needs the specified seal.
Avery Hill is about 1 mile north-east of Eltham, in Greater London. We cover Avery Hill and the rest of Greater London, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 764 places in Greater London, large and small. For work in that direction, see our London page, about 8 miles away.
Business premises anywhere in SE9, DA15 and DA16 are within our area for service penetrations. Streets here include Bexley Road, Glenure Road and Perpins Road, and sites on any of them can send details for a fixed quote.

Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking a single visit for a short list of penetrations, or a phased programme for a whole building. For a job in Avery Hill, access comes first. Send the building rules and access times with your enquiry.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.

FAQs: Avery Hill
Do you work in occupied care homes around Avery Hill?
Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.
Do you work on fire-rated sealing in hotels in Avery Hill?
Yes, where the specification calls for fire-rated sealant. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
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 site paperwork can you supply?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.
How long does a job like this take?
It depends on the scope, though a typical visit usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
How the job changes by surface
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance along with any permits your site needs.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones usually call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Site staff or a sealant specialist?
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
Signs you need fire stopping in Avery Hill
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Common reasons buildings call us in:
- Fire-rated sealant that has cracked or shrunk back
- Service penetrations left open after M&E works
- Builders’ foam or ordinary silicone in compartment walls
- Seals that don’t match their tested detail
Tenant changes at parks like Green Lane Business Park (1.2 miles south-west of Avery Hill) bring new data and services, and openings through fire-resisting walls need the specified seal.
What to look for in a quote
- How the joint faces will be prepared and primed
- Will RAMS and insurance details be available?
- Is the sealant right for the movement and the substrate?
- Who will actually carry out the work
What sealant work can’t fix
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Signing off or certifying a building’s fire stopping
- Gaps in walls that were never built as compartment walls
- Plastic pipes whose detail calls for a collar or wrap
Not sure which it is? You can ring 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
- Cable penetrations
- Pipe penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
Why deal with it now?
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. Failed sealant in a building in Avery Hill can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
