Fire stopping in Highwood, done properly
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on cable penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads, and what we are called in for most is non-fire-rated filler around services and openings left by services added after handover. For commercial sealant work in Highwood, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
A job near Highwood is typically planned around one visit, 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.
Every job we finish is backed by a 12-month workmanship guarantee, in Highwood as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Do you need fire stopping in Highwood?
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and the wrong product can split as a result. Linear joint details set a width range and movement capability, and the seal has to sit within them.
It’s worth sending us details if you spot any of the following:
- Fire seals cut back for extra cables and never reinstated
- Non-fire-rated filler around services
- Improvised or mixed-product fire seals
- Hidden openings found during inspections
Office fit-outs on sites such as Headlands Business Park (1.3 miles west of Highwood) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Why it’s worth doing now in Highwood
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Older rural buildings around Highwood 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.
A quote for service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What else we do in Highwood
Compartment walls and floors in Highwood
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. Highwood has four care or nursing homes no more than 2 miles away. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail.
Halls and meeting rooms at places like St John the Baptist sometimes gain new services, and any compartment wall crossed needs the specified seal. Wherever services are added at a hospital such as St Leonard's Hospital (5.5 miles south-west of Highwood) the compartment line has to be made good with the specified product.
Highwood is about 2 miles north-east of Ringwood, in Hampshire. We cover Highwood, with the same fixed quotes and 12-month guarantee as everywhere else. 723 places across Hampshire fall within our area, including Highwood. Our Southampton page has more on work in that area (16 miles or so).

General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
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. A poor seal in places like these tends to cost more to put right later.
Cost factors for service penetrations
A fixed quote reflects the actual work. It takes account of:
- The total length or number of joints
- Which sealant the job calls for
- Whether old sealant has to be cut out first
- Location, for remote and island sites
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Approximate linear metres or a joint schedule
- Access details, including height
- The asbestos register, for older buildings
- A wide shot and a close-up of the area
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Have penetrations checked while they can still be seen
- File the specified details where the next contractor can find them
- Treat an open penetration as a priority repair
- Keep general-purpose fillers away from compartment walls
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
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.
How a job runs
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Rural sites near Highwood may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Tell staff and tenants when we will be in
- Have the specification and drawings to hand

Advice
Questions we’re asked in Highwood
What does the BS 476 change mean for fire-rated sealant in Highwood?
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. Our part doesn’t change: the specified product, to its tested detail.
Do you take on work at healthcare sites like St Leonard's Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can you handle several sites?
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.
Is your workmanship covered by a guarantee?
Yes. Our workmanship is backed for 12 months on every job.
