Fire stopping in Hendon, done properly
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. Most enquiries involve openings found when ceilings come down for a refit and head-of-wall gaps with no fire seal, across cable penetrations, service gaps in risers and linear gaps at wall heads. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Hendon is the same: the right product in a properly prepared joint.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What happens if it’s left?
An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Failed sealant in a building in Hendon can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Access can matter as much as the joints themselves: 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.

Signs you need fire stopping in Hendon
Some service penetrations were never sealed at all. Inspections, refurbishments and ceiling access normally bring them to light.
Common reasons buildings call us in:
- Old intumescent sealant that has split away
- Builders’ foam or ordinary silicone in compartment walls
- Openings found when ceilings come down for a refit
- Seals disturbed by maintenance and left open
Campus buildings at universities such as Middlesex University (to the north-west of Hendon) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.
Questions to ask before you book
- Their approach to joint depth and backing
- Will failed sealant be removed rather than covered?
- Which product they’ll use, and why it suits the joint
- Health and safety accreditation such as CHAS
What the job involves on each surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.
Quoting for work in Hendon
These are the things that shape the price:
- Any access equipment needed
- Joint width, depth and condition
- The total length or number of joints
- Site requirements such as inductions and permits
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.
Sending details for a quote
Diagnosis starts before we arrive. Let us know:
- Photos of the joints, close up and from further back
- Whether an asbestos survey exists
- Access details, including height
- Whether the building will be occupied during the work
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
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 any cutting starts, with the work itself usually taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- For older buildings, check the asbestos register before work
- Tell staff and tenants when we’ll be in
- Share your working hours and any access restrictions
Getting a fixed quote
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or email us.
Advice
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Construction that lacks the fire resistance the seal relies on
- Deciding what a wall or floor needs, which belongs to the designer
- Approving the work on behalf of building control
If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think.
Joints and surfaces we work on
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Cable penetrations
- Service gaps in risers
- Linear gaps at wall heads
What else we do in Hendon
Your questions answered
Is hospital work, at somewhere like BMI Hendon Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does your area include sites such as Brent Cross Shopping Park, near Hendon?
Yes. Estates, retail parks and business parks around Hendon, Brent Cross Shopping Park among them, are all within reach. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
What do BS EN 1366-3 and BS EN 13501-2 mean?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Fire stopping in Hendon: the local picture
Hendon has four care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. We install fire-rated sealant to the tested detail where it is specified. With tenants changing and fit-outs following, London buildings see service routes altered again and again. We seal to the specification and the product’s tested detail, working within the building’s permits.
Colleges such as College of North West London, 2.4 miles south-west of Hendon, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. For a unit at a centre such as Brent Cross Shopping Centre, which lies south of Hendon, penetration seals are worth checking after each shop fit.
