Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Issuing fire ratings or certificates for seals
- Construction that lacks the fire resistance the seal relies on
- Designing or specifying fire stopping, which sits with the designer or fire engineer
Not sure which it is? You can call the office on 01277 525 020 or email us and we will tell you honestly before you book.
Surfaces we seal
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Cable penetrations
- Linear gaps at wall heads
- Service gaps in risers
Fire stopping in Lambeth, done properly
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on pipe penetrations, joints between fire-resisting walls and floors and service gaps in risers, and the usual reasons a site gets in touch are fire seals cut back for extra cables and never reinstated and openings found when ceilings come down for a refit. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lambeth it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
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.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

When to bring in a specialist
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Service penetrations in Lambeth buildings
A 2-mile radius around Lambeth takes in a good number of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. With tenants changing and fit-outs following, London buildings see service routes altered again and again. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
Colleges such as Chelsea College of Art & Design (to the west of Lambeth) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. For an estates team at a campus like London South Bank University (0.9 miles north-east of Lambeth), summer M&E works are usually followed by a round of penetration sealing.
Lambeth is about 1 mile south-west of London, in Greater London. If you are looking for fire stopping in Lambeth, we can help, as we do across Greater London. We work across 764 places in Greater London, from busy centres to rural villages.

What sets the cost
These are the things that shape the price:
- Phasing around occupants
- How much existing material needs removing
- Site requirements such as inductions and permits
- Distance, for remote addresses
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
- The site address and postcode
- Any dates the work must fit around
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or use the quote form with what you know.

Diagnose, treat, sign off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in Lambeth, access comes first. Give us the hours we can be on site and we will schedule to suit.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Tell us what induction or permit system the site runs
- Point out parking and an unloading spot

How the job changes by surface
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.
Questions about Lambeth
Is a hospital such as Evelina London Children's Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How does the move away from BS 476 affect penetration seals in Lambeth?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How do we ask for a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Common problems we fix in Lambeth
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
If one of these sounds familiar, it’s time for a closer look:
- Builders’ foam or ordinary silicone in compartment walls
- Seals that don’t match their tested detail
- Fire-rated sealant that has cracked or shrunk back
- Fire-stopping items raised at inspection or handover
Shop fits in centres such as Southernwood Retail Park (1.9 miles east of Lambeth) can bring new services through fire-resisting walls between units, which then need the specified seal.
What your quote should include
- Are they CHAS accredited or on Constructionline?
- What level of public liability insurance do they hold?
- Which product they’ll use, and why it suits the joint
- Do they follow the manufacturer’s priming guidance?
