Compartments and services around Nyewood
Nyewood lies roughly 48 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. In England, Approved Document B covers fire stopping of 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. We install whatever has been specified, to the product’s tested detail.
Large healthcare estates like Petersfield Community Hospital (3.7 miles west of Nyewood) change their services often, so penetration seals are worth checking after M&E work.

How we handle fire stopping in Nyewood
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. If you’re dealing with hidden openings found during inspections and improvised or mixed-product fire seals, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Nyewood is the same: the right product in a properly prepared joint.
Rural conversions around Nyewood can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

When to call us in Nyewood
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, which then have to be put right.
Site and facilities staff are often the first to spot these:
- Service penetrations left open after M&E works
- Unsealed penetrations discovered above suspended ceilings
- Fire stopping installed outside its tested range
- Head-of-wall gaps with no fire seal
For a unit at a site such as Upper Adhurst Industrial Park, 2.9 miles north-west of Nyewood, new power or data runs between office and warehouse can breach a compartment wall.
Questions to ask before you book
- Their approach to joint depth and backing
- How long is the guarantee, and what does it include?
- Whether their applicators hold CSCS cards
- Which product they’ll use, and why it suits the joint
How a job runs
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Nyewood, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- 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.
- Each opening is checked for wall or floor type, service, gap and depth.
- 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 your opening times and when work is allowed
- Tell us which areas need to stay in use
- Point out parking and an unloading spot

How the job changes by 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, so we check each one.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance.
Cost factors for service penetrations
The price varies from site to site. It mainly depends on:
- The product specified
- Distance, for remote addresses
- How much there is to seal
- Induction, permit and paperwork requirements
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- The postcode of the building
- Whether the building will be occupied during the work
- Approximate linear metres or a joint schedule
- Any specification or named product
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send photos by email.
What we can’t put right
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Reviewing a building’s overall fire safety
- Openings that need collars, wraps, batts or boards rather than sealant
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
Where we work in Nyewood
- Joints between fire-resisting walls and floors

FAQs: Nyewood
Can you work on a hospital site such as Petersfield Community Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Does your area include sites such as Upper Adhurst Industrial Park, near Nyewood?
Yes. Our area takes in Nyewood and its surroundings, with estates and business parks such as Upper Adhurst Industrial Park included. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Is sealant suitable for all service openings?
No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we flag those rather than improvise.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you have third-party installer accreditation for fire stopping?
No, and we’d rather be clear about that. Some clients require third-party installer schemes even though the law doesn’t, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Looking after the joints
To get the most from the new sealant:
- Get seals inspected before ceilings and boxing close
- Check risers and ceiling voids after each round of works
- Foam or ordinary sealant is never a fire-seal repair
- Flag new cables with no seal around them
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail.
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.
