Fire stopping near Highcliffe
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How the quote is worked out
We price every job individually. The things that drive the figure:
- Site requirements such as inductions and permits
- Working within restricted access windows
- Travel to remote or island sites
- Quantities, in metres or numbers
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
What we need to price the job
However big the job, the same details help:
- Photos of the joints, close up and from further back
- When you need the work done
- The type of building and who uses it
- Asbestos survey details if the building is older
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or email drawings and photos to discuss it first.
About our fire stopping in Highcliffe
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. The enquiries we see most involve builders’ foam or ordinary silicone in compartment walls and old intumescent sealant that has split away, on linear gaps at wall heads, pipe penetrations and cable penetrations. Whoever orders the work in Highcliffe, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Highcliffe, many commercial buildings are conversions or extensions of older ones, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What the job involves on each surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe. If the detail needs something beyond sealant, we tell you.
Highcliffe: questions and answers
Is a hospital such as Leigh House Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is a smaller place like Highcliffe outside your area?
Not at all. Highcliffe is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can you seal any opening with fire-rated sealant?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards.
Can you reseal penetrations after our M&E works?
Yes, where there is a specification for those walls and floors. Openings left by new services are among the most common jobs we see.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you offer coloured sealant?
It depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Fire stopping around Highcliffe: how the place shapes the job
A 2-mile radius around Highcliffe takes in a good number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Highcliffe lies roughly 60 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
Where a unit on an estate such as Bar End Industrial Estate, under half a mile south-west of Highcliffe, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Wherever services are added at a hospital such as Leigh House Hospital, 0.9 miles north-east of Highcliffe, the compartment line has to be made good with the specified product.
Highcliffe is about 1 mile east of Winchester, in Hampshire. Any commercial site in Highcliffe is covered. Across Hampshire, 723 places are covered, Highcliffe among them. For work in that direction, see our Southampton page, about 10 miles away.

Why act early in Highcliffe
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. Small buildings around Highcliffe suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you’re ready.

On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. What matters most for a job in Highcliffe is a clear list of what needs doing. You’ll then get a fixed price for the work.
- First we go through the drawings, schedule or specification for the seals.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Tell us your opening times and when work is allowed
- Point out any areas we must not close
- Move anything stored against the joints
Ask for a quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Issuing fire ratings or certificates for seals
- Construction that lacks the fire resistance the seal relies on
- Openings that need collars, wraps, batts or boards rather than sealant
If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Common problems we fix in Highcliffe
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in.
Any of the following is a good reason to get the joints checked over:
- Openings left by services added after handover
- Seals that don’t match their tested detail
- Seals disturbed by maintenance and left open
- Open linear gaps along the top of fire-resisting walls
For a unit at a centre such as Moorside Retail Park (0.9 miles north of Highcliffe), penetration seals are worth checking after each shop fit.
