Fire stopping across Eastfields
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Planning a London job such as one in Eastfields starts with access. Give us the hours we can be on site and we’ll schedule to suit.
- We read the specification, drawings or penetration schedule you send.
- On site, each opening is checked against the tested detail it is meant to follow.
- 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.
What we need from you
- Make sure the joints can be reached
- Let us know about inductions and permits
- Let building users know which areas are affected

About our fire stopping in Eastfields
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. If you are dealing with hidden openings found during inspections and builders’ foam or ordinary silicone in compartment walls, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Eastfields it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

If you’re not sure, just phone 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Your questions answered
Can you seal around new services in a hotel near Eastfields?
Yes, to the specification and the product’s tested detail. Each seal follows the tested detail, and rooms are done in turn.
Can work at a site such as University of the Arts London fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Do you offer coloured sealant?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Cost factors for service penetrations
To price the job, we consider:
- Access and working height
- Which sealant the job calls for
- Distance, for remote addresses
- The total length or number of joints
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Before you send an enquiry
However big the job, these details speed things up:
- Any dates the work must fit around
- How the joints are reached, and at what height
- Clear photographs of the problem areas
- The asbestos register, for older buildings
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.
Fire stopping in Eastfields: the local picture
For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
For a site team at a college like South Thames College Tooting Centre, 1.4 miles to the north-west of Eastfields, fire-rated sealing is best scheduled after the summer works. Shop fits in centres such as Priory Retail Park, 1.2 miles north-west of Eastfields, can bring new services through fire-resisting walls between units, which then need the specified seal.
Eastfields is about 3 miles south-east of Wimbledon, in Greater London. Businesses, contractors and managing agents in Eastfields can call on us for service penetrations, as part of our coverage of Greater London.

Around Eastfields

Commercial clients in Eastfields
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

When to call us in Eastfields
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.
If one of these sounds familiar, it’s time for a closer look:
- Unsealed joints where partitions meet the slab
- Fire sealant pulled out of the opening
- Hidden openings found during inspections
- Service penetrations left open after M&E works
On a hospital site such as The Wilson Hospital, which lies south-west of Eastfields, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Questions to ask before you book
- Can the work be phased to keep areas open?
- How long is the guarantee, and what does it include?
- Will failed sealant be removed rather than covered?
- Will RAMS and insurance details be available?
