Building owners, agents and FMs in North Ockendon
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
How we handle fire stopping in North Ockendon
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you’re dealing with old intumescent sealant that has split away and unsealed joints where partitions meet the slab, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in North Ockendon, that means joint design, primers and backing rod as standard.
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’ll hear it from us.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

FAQs: North Ockendon
Will you plan work around the academic year at somewhere like New City College?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them. All of Greater London is inside the ULEZ, and our planning allows for it
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
How many days will you need on site?
That varies with the scale of the job, but the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Penetration seals near North Ockendon
For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
In a building such as Church of St Mary Magdalene, any service penetration through a fire-resisting wall should be sealed to the specified detail. Tenant changes at centres like Ealing Broadway Centre (2.2 miles south of North Ockendon) often mean new services through walls between units.

Cost factors for service penetrations
What shapes the price:
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
- The site’s rules and procedures
- Any access equipment needed
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
What to include in your enquiry
However big the job, the same details help:
- Rough lengths or quantities, or drawings if you have them
- The asbestos register, for older buildings
- The product your specification calls for
- The postcode of the building
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or email us.
How the job changes by surface
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we will never swap a specified collar for sealant.
Metal pipes
Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.

What else we do in North Ockendon
When to call us in North Ockendon
Openings in fire-resisting walls usually appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
These are often picked up first by site or facilities staff:
- Fire seals cut back for extra cables and never reinstated
- Openings left by services added after handover
- Unsealed penetrations discovered above suspended ceilings
- Open linear gaps along the top of fire-resisting walls
At a healthcare site like St George's Hospital, 3 miles west of North Ockendon, new services through compartment walls are a constant, and each needs the specified seal.

- What the guarantee covers, and for how long
- Can the work be phased to keep areas open?
- Health and safety accreditation such as CHAS
After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Foam or ordinary sealant is never a fire-seal repair
- Agree the fire-stopping specification before services go in
- Flag new cables with no seal around them
- Get seals inspected before ceilings and boxing close
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Planning a London job such as one in North Ockendon starts with access: 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’ll schedule to suit.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- 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
- Flag any permit to work we will need
- Make sure the joints can be reached
- Point out parking and an unloading spot
