Fire stopping in Long Green: the local picture
Several hotels sit less than 2 miles from Long Green. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Long Green lies roughly 39 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, and the gaps need sealing with the specified product.
Hospital estates such as Braintree Community Hospital (to the north-west of Long Green) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. On a site such as Lanham Business Park, 0.6 miles east of Long Green, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Colleges such as Braintree College (to the north-west of Long Green) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

A single leaking joint is often how a building in Long Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a smaller site near Long Green, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

Different surfaces, different methods
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement, along the full length of the run.
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area.
For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
After the work
For the best life from the joints:
- Flag new cables with no seal around them
- Check risers and ceiling voids after each round of works
- Leave fire sealant to cure fully before covering it
- Keep general-purpose fillers away from compartment walls
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.
Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Openings that need collars, wraps, batts or boards rather than sealant
- Issuing fire ratings or certificates for seals
- 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.
Joints and surfaces we work on
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Cable penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Service gaps in risers
Why it’s worth doing now in Long Green
Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. Older rural buildings around Long Green move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
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.

Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. For work around Long Green, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- 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.
- 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
- Tell us what induction or permit system the site runs
- Send your site hours and access windows
- Tell us which areas need to stay in use
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Long Green: questions and answers
Is hospital work, at somewhere like Braintree Community Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Can you seal penetrations in a hotel in Long Green after a refit?
Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Is Long Green in your area?
Yes. We take on work across Long Green, and the same phone number covers every area.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
