When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Putting right a botched joint often costs more than sealing it well at the start, 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.
How we handle fire stopping in Rotherhithe
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, give us a call on 01277 525 020 or email the details over with the schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. The enquiries we see most involve unsealed penetrations discovered above suspended ceilings and seals that don’t match their tested detail, across linear gaps at wall heads, cable penetrations and pipe penetrations. Facilities teams, main contractors and managing agents in Rotherhithe tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Signs you need fire stopping in Rotherhithe
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in.
Any of the following is a good reason to get the joints checked over:
- Unsealed penetrations discovered above suspended ceilings
- Seals that don’t match their tested detail
- Open linear gaps along the top of fire-resisting walls
- Fire-rated sealant that has cracked or shrunk back
For an estates team at a campus like University of Cumbria in London (1.1 miles north-east of Rotherhithe), summer M&E works are typically followed by a round of penetration sealing.

What the job involves on each surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest so we know it sits within the tested range, and any that don’t are flagged.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.
Penetration seals near Rotherhithe
In England, Approved Document B covers fire stopping of openings and penetrations. 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. Either way, we install the specified product to its tested detail. With tenants changing and fit-outs following, London buildings see service routes altered again and again. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
For a unit at a centre such as Surrey Quays Shopping Centre, under half a mile to the south-west of Rotherhithe, penetration seals are worth checking after each shop fit. For a site team at a college like South Quay College, which lies east of Rotherhithe, fire-rated sealing is best scheduled after the summer works.

Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking a single visit for a short list of penetrations, or a phased programme for a whole building. All of Greater London is in the ULEZ, and kerbside space in Rotherhithe can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- 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.
What we need from you
- Share your working hours and any access restrictions
- Tell us what induction or permit system the site runs
- Tell us which areas need to stay in use

Why it’s worth doing now in Rotherhithe
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down. In Rotherhithe, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Why us?
- Joints cleaned back to sound surfaces
- Workmanship guaranteed for 12 months
- Constructionline member
- Fixed quotes based on photos, drawings or a visit

Common questions from Rotherhithe clients
Is City Business Centre, near Rotherhithe, within your area?
Yes. Estates, retail parks and business parks around Rotherhithe, City Business Centre among them, are all within reach. To start, just call 01277 525 020 or email us with the unit, the joints involved and your access times.
Can you work in a care home near Rotherhithe with residents in?
Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you hold third-party fire-stopping installer certification?
No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them. Where it isn’t required, we install the specified sealant to the maker’s details.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you offer coloured sealant?
It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
