How we handle fire stopping in Oakleigh Park
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. Most enquiries involve damaged fire seals in risers and voids and fire-rated sealant that has cracked or shrunk back, across joints between fire-resisting walls and floors, service gaps in risers and small duct penetrations where the tested detail allows. Looking for mastic applicators who cover Oakleigh Park? We have been sealing commercial buildings since 2005.
In a London area such as Oakleigh Park, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

After the work
Regular inspection catches problems early. In particular:
- Leave fire sealant to cure fully before covering it
- Arrange inspection before areas are covered up
- Don’t let anyone top up a fire seal with the wrong product
- Include service cupboards in routine inspections
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.
Oakleigh Park: questions and answers
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry.
Can you take on a job at a hospital such as Finchley Memorial Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
What do you charge?
There isn’t a price list, because every site is different. Send photos or drawings and we will price it at a fixed figure.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Will you write the fire-stopping specification?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
Which standards are fire seals tested to?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. An EI 60 seal kept its integrity and insulation for 60 minutes as tested and the installation has to match the test.
Leave it or put it right?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed. Getting scaffold, permits or access booked in Oakleigh Park takes effort, so it makes sense to deal with every failing joint while access is in place.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Doing it in-house
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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Fire stopping in Oakleigh Park: the local picture
Oakleigh Park has six care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.
Large healthcare estates like Finchley Memorial Hospital, 1.4 miles south of Oakleigh Park, change their services often, so penetration seals are worth checking after M&E work. In a retail centre such as Grand Arcade, 0.9 miles south of Oakleigh Park, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.

Signs you need fire stopping in Oakleigh Park
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in.
Most enquiries start with one or more of the following:
- Fire seals cut back for extra cables and never reinstated
- Old intumescent sealant that has split away
- Penetration schedules that need working through
- Non-fire-rated filler around services
On estates like Finchley Industrial Centre, which lies south-west of Oakleigh Park, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Who will actually carry out the work
- How long is the guarantee, and what does it include?
- Are they CHAS accredited or on Constructionline?

From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself normally taking anything from one day to a planned run of visits, depending on the number of seals and the access. For a job in Oakleigh Park, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- We read the specification, drawings or penetration schedule you send.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Warn occupants and staff about the work
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000
