Greensted: questions and answers
Is Hallsford Bridge Industrial Estate, near Greensted, within your area?
Yes, sites like Hallsford Bridge Industrial Estate are within our area, along with the rest of Greensted. Send details of the unit and the work through our quote form for a quick quote.
What happens to BS 476 references for fire stopping in Greensted?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
What happens if old sealant might contain asbestos?
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.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
How we handle fire stopping in Greensted
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, not a rule of thumb. We work on service gaps in risers, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and what we are called in for most is openings left by services added after handover and unsealed penetrations discovered above suspended ceilings. Whoever orders the work in Greensted, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For a smaller site near Greensted, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Do you need fire stopping in Greensted?
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
Common reasons buildings call us in:
- Builders’ foam or ordinary silicone in compartment walls
- Damaged fire seals in risers and voids
- Head-of-wall gaps with no fire seal
- Improvised or mixed-product fire seals
Theatres, wards and plant rooms at sites like St. Margaret's Hospital, 4.4 miles west of Greensted, all have compartment walls crossed by services.
What your quote should include
- What the guarantee covers, and for how long
- Proof of insurance
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their plan for phasing and protecting the area

After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep product data and details in the fire safety file
- Leave fire sealant to cure fully before covering it
- Have penetrations checked while they can still be seen
- Report damaged or disturbed seals as soon as they’re spotted
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, and report them promptly.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
Where services cross fire walls in Greensted
Approved Document B is the English guidance that covers fire stopping around 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. Either way, we install the specified product to its tested detail. Greensted lies roughly 20 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
For a unit at a site such as Hallsford Bridge Industrial Estate, 1.5 miles south-east of Greensted, new power or data runs between office and warehouse can breach a compartment wall. Older community buildings such as Greensted Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Rural sites near Greensted may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Send any specification or drawings in advance
- Tell us what induction or permit system the site runs
- Make sure the joints can be reached
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Honest limits
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Deciding what a wall or floor needs, which belongs to the designer
- Walls or floors that aren’t fire-resisting to begin with
- Fire doors, dampers or other fire safety equipment
If you are not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Linear gaps at wall heads
Different surfaces, different methods
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point against the detail’s limits, and any outside it are raised with you.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Cost factors for service penetrations
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Induction, permit and paperwork requirements
- How much existing material needs removing
- Travel to remote or island sites
- Phasing around occupants
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- The postcode of the building
- Approximate linear metres or a joint schedule
- The product your specification calls for
- Photos of the joints, close up and from further back
For a fixed quote, phone 01277 525 020 or send photos by email, telling us the site location and the nature of the job. Our quote form is another easy route.
