How we handle fire stopping in South Ambersham
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. Most enquiries involve hidden openings found during inspections and service penetrations left open after M&E works, across linear gaps at wall heads, cable penetrations and service gaps in risers. One point of contact handles commercial sealant work in South Ambersham from the first photographs to the final walk-round, whether it’s one building or several.
A job near South Ambersham is typically planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Why deal with it now?
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. For buildings around smaller places like South Ambersham, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Common problems we fix in South Ambersham
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, which then have to be put right.
Clients normally get in touch after noticing something like this:
- Improvised or mixed-product fire seals
- Damaged fire seals in risers and voids
- Expanding foam used as fire stopping
- Open linear gaps along the top of fire-resisting walls
Wherever services are added at a hospital such as Midhurst Community Hospital (to the north-west of South Ambersham) the compartment line has to be made good with the specified product.
Questions to ask before you book
- What level of public liability insurance do they hold?
- How joint depth will be controlled
- Will CSCS-carded applicators be on site?
- Can the work be phased to keep areas open?
Cost factors for service penetrations
Each job is priced on its own details. The main factors are:
- How accessible the joints are
- Joint width, depth and condition
- Distance, for remote addresses
- Phasing around occupants
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.
Details that help us quote
A few photos plus some basic facts will normally do. Please tell us:
- Whether an asbestos survey exists

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or email us with what you know.
How a job runs
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Rural sites near South Ambersham may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- 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.
- Mineral wool or other backing goes in wherever the detail asks.
- 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.
Getting the site ready
- Arrange parking or a loading space
- Send your site hours and access windows
- Let building users know which areas are affected

What the job involves on each surface
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers.

Service penetrations in South Ambersham buildings
The area within 2 miles of South Ambersham holds a 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. South Ambersham is about 44 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
Older community buildings such as Church of St James that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Where a unit on an estate such as Holmbush Industrial Estate (2.2 miles west of South Ambersham), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
