You’ll have a fixed quote before work starts.

Advice
About our fire stopping in North Mundham
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you have fire-rated sealant that has cracked or shrunk back and non-fire-rated filler around services, we can help, whatever the surface. A single leaking joint is often how a building in North Mundham first comes to us: we look at the rest while we are there and tell you what we find.
A job near North Mundham is normally planned around one visit, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
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.

Questions about North Mundham
Do you seal service penetrations in hotels around North Mundham?
Yes, to the specification and the product’s tested detail. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we will tell you if the detail calls for a collar, wrap or batt instead.
What does the BS 476 change mean for fire-rated sealant in North Mundham?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
How do we ask for a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, let us know and we will send them with the quote.
What happens if it’s left?
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. Around North Mundham, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Settle who seals which penetrations at the start of a project
- Arrange inspection before areas are covered up
- Look above ceilings when tiles are lifted for other jobs
- Make fire stopping part of every scope that crosses a fire-resisting wall
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.
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.
What affects the price in North Mundham
Quotes vary with the job. It mainly depends on:
- Induction, permit and paperwork requirements
- Removal of failed or old sealant
- How much there is to seal
- Joint width, depth and condition
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- The type of building and who uses it
- The product your specification calls for
- Access details, including height
- Where the site is, with the postcode
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.
Fire stopping in North Mundham: the local picture
For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. North Mundham has a number of hotels close by, all within 2 miles. 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.
For a unit at a site such as Quarry Lane Industrial Estate (1.2 miles north of North Mundham), new power or data runs between office and warehouse can breach a compartment wall. For an estates team at a campus like University of Chichester, 1.8 miles east of North Mundham, summer M&E works are usually followed by a round of penetration sealing.

Do you need fire stopping in North Mundham?
Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped and the opening isn’t always resealed.
Most enquiries start with one or more of the following:
- Fire sealant pulled out of the opening
- Snag lists that include open service penetrations
- Service penetrations left open after M&E works
- Seals disturbed by maintenance and left open
In a building such as The Parish Church of St Stephen, any service penetration through a fire-resisting wall should be sealed to the specified detail.

What the job involves on each surface
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.
