About our fire stopping in Wood Green
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. The enquiries we see most involve damaged fire seals in risers and voids and snag lists that include open service penetrations, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and linear gaps at wall heads. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Wood Green is the same: the right product in a properly prepared joint.
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.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones normally call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
Questions about Wood Green
Will you work in a care home in Wood Green without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
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. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
How much does the work cost?
We don’t publish prices, as every site differs. Send photos or drawings and we will price it at a fixed figure.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
What’s the quickest route to a quote?
It works in 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?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Large openings beyond what any sealant detail covers
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly.
Surfaces we seal
- Service gaps in risers
- Pipe penetrations
- Cable penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
Fire stopping in Wood Green: the local picture
In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We seal to the specification and the product’s tested detail, working within the building’s permits.
Large healthcare estates like St Ann's Hospital, 1.5 miles south-east of Wood Green, change their services often, so penetration seals are worth checking after M&E work. For an estates team at a campus like American University in London, 2.6 miles to the south of Wood Green, summer M&E works are typically followed by a round of penetration sealing. At a college such as Haringey Sixth Form College, 1.6 miles to the east of Wood Green, checking penetration seals after summer M&E works is good practice.
Wood Green is about 3 miles south-west of Edmonton, in Greater London. We send applicators to Wood Green for service penetrations. We work across 764 places in Greater London, large and small. We also cover London, some 7 miles away.

Near you in Wood Green
Locally, jobs take us to sites close to St Thomas More Catholic School, Woodside Park and The Nag's Head pub and the streets around them.

Owners, agents and contractors
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Wood Green can form part of a wider programme.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Site staff or a sealant specialist?
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. A poor seal in places like these tends to cost more to put right later.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Other services in Wood Green
Diagnose, treat, sign off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. All of Greater London is in the ULEZ, and kerbside space in Wood Green can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- 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.
Preparing the site
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
- Tell us which areas need to stay in use

Quoting for work in Wood Green
We price every job individually. The main factors are:
- The product specified
- Whether old sealant has to be cut out first
- Working within restricted access windows

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

It doesn’t need to be a full survey. These details are enough to start:
- Any specification or named product
