How a job runs
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Have the specification and drawings to hand
- Point out any areas we must not close
- Explain the parking and delivery arrangements

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

About our fire stopping in Duckett's Green
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal. If you’re dealing with snag lists that include open service penetrations and damaged fire seals in risers and voids, we can help, on linear gaps at wall heads, pipe penetrations and small duct penetrations where the tested detail allows alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Duckett's Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What else we do in Duckett's Green
After the work
Once the work is signed off, a little attention goes a long way:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Include service cupboards in routine inspections
- Record which product was used where
- Ask the designer to confirm details early on refits
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
What the job involves on each surface
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe. If the detail needs something beyond sealant, we tell you.
Small ducts
We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.
FAQs: Duckett's Green
Will you plan work around the academic year at somewhere like American University in London?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Will you take on work at estates like Crusader Industrial Park, close to Duckett's Green?
Yes, sites like Crusader Industrial Park are within our area, along with the rest of Duckett's Green. Send details of the unit and the work through our quote form for a quick quote.
Do you certify or sign off fire stopping?
No. Approval sits with the designer, principal designer or building control. We will confirm the products and details used.
Do you offer coloured sealant?
It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
Can you tell us what fire stopping our building needs?
No, we don’t design fire stopping. With the designer’s details in hand, we can price the sealant elements, and tell you if a detail needs another product.
Penetration seals near Duckett's Green
A 2-mile radius around Duckett's Green takes in plenty of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. 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. What we install is set by the specification, and it goes in to the tested detail.
At a healthcare site like St Ann's Hospital, which lies south-east of Duckett's Green, new services through compartment walls are a constant, and each needs the specified seal. For a site team at a college like The College of Haringey, which lies east of Duckett's Green, fire-rated sealing is best scheduled after the summer works. For a unit at a centre such as The Mall Wood Green (0.6 miles north-west of Duckett's Green), penetration seals are worth checking after each shop fit.
Duckett's Green is about 3 miles north of Highbury, in Greater London. If you are looking for fire stopping in Duckett's Green, we can help, as we do across Greater London. We work across 764 places in Greater London, large and small. We also cover London, some 6 miles away.

What’s near Duckett's Green
Around Duckett's Green, our work takes us to commercial buildings near Moselle Upper School, Ducketts Common and The Queens Head pub and the streets around them. For rail, the closest station is Hornsey station, roughly 0.7 miles west of the centre. Other landmarks nearby include Greentrees Hospital (1.5 miles north) and Markfield Beam Engine and Museum (1.6 miles east). For a walk, there’s Hollow Pond and Railway Fields.
What happens if it’s left?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote when you are ready.

When to bring in a 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. Getting these wrong usually costs more in the end than doing them right.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What sets the cost
We price every job individually. The main factors are:
- Distance, for remote addresses
- The size and state of each joint
- Site requirements such as inductions and permits
- How much existing material needs removing
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Sending details for a quote
A good diagnosis starts with the right details. Tell us:
- Where the site is, with the postcode
- The asbestos register, for older buildings
- Approximate linear metres or a joint schedule
- Clear photos of the problem areas
