How we handle fire rated sealant in Northfields
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That detail is what we take care over, gap by gap. If you have sealant items on a fire risk assessment action list and gaps filled with a product that isn’t fire-rated, we can put it right, whatever the surface.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Northfields, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Quotes for fire rated sealant in Northfields
There’s no set price list, because jobs vary so much. The quote depends on:
- Working hours on commercial sites
- Whether the work is at height
- How many areas need sealing
- Any mould that needs treating
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- A few photos by email, if you can
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- Whether it’s a home or a business
Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Doors that are not fire doors in the first place
- A wall that is not a fire-resisting element to begin with
- Deciding what fire stopping a building needs
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
What we seal
- Linear gaps
- Flats & HMOs
- Pipe & cable gaps
- Plasterboard & masonry
- Door frames
- Service penetrations
Aftercare tips
A little care helps the new joints last. We recommend:
- Never patch a fire seal with standard sealant
- Look in service cupboards and ceiling voids from time to time
- Allow for resealing whenever new services are run
- Keep the record of products and locations with your fire safety documents
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

Questions from Northfields
Do you work for landlords with property near Brentford station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is parking an issue for fire rated sealant in Northfields?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Will you assess my building’s fire safety?
No. That is for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Do you seal gaps around fire door frames?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame and we’ll tell you if we spot problems with the door.
Can you tell me how many minutes the seal will last?
That isn’t something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it with a record of each location.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient.
What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. In a London area like Northfields, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts

Other services in Northfields
Fire rated sealant in Northfields: local notes
Northfields has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
As a London address, Northfields can be tricky for parking: let us know about parking bays, permits or a driveway. Rented homes near Brentford station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Northfields is about 1 mile south of Ealing, in Greater London. Whether you are in the middle of Northfields or further out, fire rated sealant is available for homes and businesses alike, from flats and houses to offices and hotels. Northfields is one of 764 places in Greater London we cover. There’s also a page for London, about 9 miles away.
Every address in W5, W13 and TW8 is covered for fire rated sealant, from the main roads to the quietest streets. Whether your property is on Burns Road, South Road and Elers Road or anywhere close by, we can help. Northfields sits on or near the A3002. Neighbouring places we cover for fire rated sealant include Brentford (1 mile south-east), Gillette Corner (1 mile south-west), Brentford End (1 mile south), Osterley (2 miles south-west) and Spring Grove (2 miles south-west).

Nearby too are Library for Iranian Studies (1.8 miles east) and Lammas Park (within half a mile north). For rail, the closest station is Brentford station, about 0.8 miles south of the centre.

Why deal with it now?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Northfields, the repair is bigger than the sealant job would have been.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

What we’re called out for in Northfields
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Common reasons people contact us are:
- Gaps flagged on a fire risk assessment
- Gaps around pipes and cables through fire-resisting walls
- Gaps where walls meet ceilings or slabs
- Gaps filled with a product that isn’t fire-rated
For site and facilities teams at buildings such as Mount Carmel Catholic Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
Questions to ask before you book
- How much experience the applicator has
- How long the guarantee is
- What product goes in the joint
- When the joint can take water or movement
