Fire stopping across Oakwood
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Fire stopping in Oakwood
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. If you’re dealing with fire stopping installed outside its tested range and seals disturbed by maintenance and left open, we can put it right, on small duct penetrations where the tested detail allows, linear gaps at wall heads and pipe penetrations alike. A single leaking joint is often how a building in Oakwood first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you’ll hear it from us.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Honest limits
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Large openings beyond what any sealant detail covers
- Deciding what a wall or floor needs, which belongs to the designer
- Gaps in walls that were never built as compartment walls
If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think before you book.
Where we work in Oakwood

Why deal with it now?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach. Failed sealant in a building in Oakwood can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Penetration seals near Oakwood
Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. A 2-mile radius around Oakwood takes in a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
At a healthcare site like Priory Hospital, which lies south-east of Oakwood, new services through compartment walls are a constant, and each needs the specified seal. Office fit-outs on sites such as North London Business Park (1.6 miles south-west of Oakwood) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. In a hotel such as Southgate Hotel London, 0.8 miles to the south of Oakwood, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
Oakwood is about 2 miles west of Enfield, in Greater London. Oakwood sits inside our coverage and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else.

Our process
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. All of Greater London is in the ULEZ, and kerbside space in Oakwood can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we confirm the product and tested details named in the specification.
- 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.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000
- Let us know about inductions and permits
Getting a fixed quote
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or send details through our quote form.
Advice
Different surfaces, different methods
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits.
Plastic pipes
Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough.

What else we do in Oakwood
Your questions answered
Do you take on work at healthcare sites like Priory Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is North London Business Park, near Oakwood, within your area?
Yes. Estates, retail parks and business parks around Oakwood, North London Business Park among them, are all within reach. To start, just call the office on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Do you guarantee your work?
Yes. Workmanship is guaranteed for 12 months.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Can you reseal penetrations after our M&E works?
Yes. Share the penetration schedule and product details and a fixed quote follows. We can follow the services contractor floor by floor keeping pace with the programme.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Check risers and ceiling voids after each round of works
- Record which product was used where
- Don’t let anyone top up a fire seal with the wrong product
- Flag new cables with no seal around them
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.
Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
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, which is what makes a joint last.
