About our fire stopping in Hadley Wood
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you are dealing with fire-stopping items raised at inspection or handover and seals that don’t match their tested detail, we can put it right, on linear gaps at wall heads, small duct penetrations where the tested detail allows and service gaps in risers alike. A specialist sealant contractor works differently from a general builder: on jobs in Hadley Wood, preparation and product choice get the time they need.
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.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Flag new cables with no seal around them
- Foam or ordinary sealant is never a fire-seal repair
- Ask the designer to confirm details early on refits
- Have penetrations checked while they can still be seen
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
Service penetrations in Hadley Wood buildings
Five care or nursing homes sit less than 2 miles from Hadley Wood. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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.
Shop fits in centres such as Spires Shopping Centre (to the west of Hadley Wood) can bring new services through fire-resisting walls between units, which then need the specified seal. On a hospital site such as Potters Bar Community Hospital (1.8 miles north of Hadley Wood), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

What the job involves on each surface
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
When to call us in Hadley Wood
Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.
Typical triggers for a call:
- Non-fire-rated filler around services
- Improvised or mixed-product fire seals
- Damaged fire seals in risers and voids
- Snag lists that include open service penetrations
Colleges such as Oak Hill College, 1.9 miles to the south-east of Hadley Wood, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Common questions from Hadley Wood clients
Can work at a site such as Oak Hill College fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Does your area include sites such as Hadley Manor Trading Estate, near Hadley Wood?
Yes, sites like Hadley Manor Trading Estate are within our area, along with the rest of Hadley Wood. A few photos and the unit address let us price the work.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
Why deal with it now?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first 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.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What else we do in Hadley Wood
What sets the cost
We price every job individually. The things that drive the figure:
- Whether the work must be split into stages
- The site’s rules and procedures
- Which sealant the job calls for
- Access and working height
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- How the joints are reached, and at what height
- Drawings or a marked-up plan, if available
- The postcode of the building
- Any specification or named product
For a fixed quote, speak to us on 01277 525 020 or email the details over, telling us the site location and the nature of the job. You can also send details through our quote form.
Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We start with your penetration schedule, drawings or specification.
- 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.
- We tell you about openings that need a different product.
Getting the site ready
