About our fire stopping in Golders Green
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. If you’re dealing with openings found when ceilings come down for a refit and damaged fire seals in risers and voids, we can put it right. Looking for mastic applicators who cover Golders Green? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
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.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Golders Green: questions and answers
Can you seal penetrations in a hotel in Golders Green after a refit?
Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.
Can you cope with the access rules in a London building?
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’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
How long does a typical visit 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. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months.
Quoting for work in Golders Green
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- The site’s rules and procedures
- Which sealant the job calls for
- Quantities, in metres or numbers
- Whether old sealant has to be cut out first
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
What to include in your enquiry
To price the job accurately, we need to understand the site. Send us:
- Whether an asbestos survey exists
- A wide shot and a close-up of the area
- Access details, including height
- Any specification or named product
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Plastic pipes whose detail calls for a collar or wrap
- Writing the fire-stopping specification
- Approving the work on behalf of building control
If you are not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Where services cross fire walls in Golders Green
London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We seal to the specification and the product’s tested detail, working within the building’s permits. 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. Our part stays the same: the specified product, installed to its tested detail.
For an estates team at a campus like Middlesex University, which lies north-west of Golders Green, summer M&E works are usually followed by a round of penetration sealing. Hospital estates such as Nuffield Health Highgate Hospital, 1.8 miles to the east of Golders Green, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Signs you need fire stopping in Golders Green
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and the wrong product can split as a result. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Look out for the following:
- Old intumescent sealant that has split away
- Expanding foam used as fire stopping
- Openings left by services added after handover
- Head-of-wall gaps with no fire seal
Shop fits in centres such as Brent Cross Shopping Centre (1.1 miles west of Golders Green) can bring new services through fire-resisting walls between units, which then need the specified seal.
What your quote should include
- Their public liability cover
- How the joint faces will be prepared and primed
- The named product and why it was chosen
- Are they CHAS accredited or on Constructionline?
Surface by surface
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.
On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For a job in Golders Green, access comes first. Give us the hours we can be on site and we will schedule to suit.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Flag any permit to work we will need
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work

Advice
Leave it or put it right?
Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
