Fire stopping for businesses in Castle Green

Work for main contractors and building owners
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Castle Green can sit alongside others in a wider programme across Greater London.
Fire stopping in Castle Green
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Castle Green. If you are dealing with seals disturbed by maintenance and left open and old intumescent sealant that has split away, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Castle Green it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

What affects the price in Castle Green
Quotes vary with the job. Expect it to depend on:
- Which sealant the job calls for
- Site requirements such as inductions and permits
- How much there is to seal
- The size and state of each joint
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
Before you send an enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- The postcode of the building
- What the building is and how it’s used
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email the details over to discuss it first.
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Keep product data and details in the fire safety file
- Ask the designer to confirm details early on refits
- Treat an open penetration as a priority repair
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.
Questions we are asked in Castle Green
Do you work in occupied care homes around Castle Green?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Do you design or specify fire stopping?
No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it and point out anything needing another product.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Are you members of a third-party fire-stopping installer scheme?
No. We don’t hold a third-party fire-stopping installer certificate. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we will say so straight away rather than waste your time.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Surface by 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.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking anything from one day to a planned run of visits, depending on the number of seals and the access. All of Greater London is in the ULEZ, and kerbside space in Castle Green can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- 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.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Confirm the product named in the specification
- Tell us which areas need to stay in use
- Let us know about inductions and permits
Quotes
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Advice
Service penetrations in Castle Green buildings
In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. We install fire-rated sealant where it is specified and work within the building manager’s permit system. There are three care or nursing homes within about 2 miles of Castle Green. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail.
Residences at universities like University of East London (to the south-west of Castle Green) have compartment walls that must be resealed whenever services change. Halls and meeting rooms at places like St John the Divine sometimes gain new services, and any compartment wall crossed needs the specified seal. For a site team at a college like The Adult College (0.8 miles north-west of Castle Green), fire-rated sealing is best scheduled after the summer works.
