Fire stopping in Sidlesham
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. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you have fire seals cut back for extra cables and never reinstated and improvised or mixed-product fire seals, we can help. Most enquiries from Sidlesham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
A job near Sidlesham 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.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Service penetrations in Sidlesham buildings
Approved Document B is the English guidance that covers fire stopping around 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. Either way, we install the specified product to its tested detail. Sidlesham is about 58 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
For a building at a site such as Enborne Business Park, which lies south of Sidlesham, a check of penetration seals after each fit-out is good practice. For a building such as St Mary Our Lady Sidlesham, new heating or data runs are the usual reason penetrations need sealing. Workshops and IT rooms at colleges like West Sussex Alternative Provision College (to the north of Sidlesham) are re-serviced often, leaving penetrations to seal.

Why it’s worth doing now in Sidlesham
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. One visit to deal with every failing joint makes more sense than several trips to a place like Sidlesham, rather than one at a time. Send photos of each area and we will quote for the lot.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Aftercare for building managers
To get the most from the new sealant:
- Check risers and ceiling voids after each round of works
- Arrange inspection before areas are covered up
- File the specified details where the next contractor can find them
- Flag new cables with no seal around them
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.
How the quote is worked out
What shapes the price:
- Travel to remote or island sites
- How much there is to seal
- Site requirements such as inductions and permits
- Working within restricted access windows
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- When you need the work done
- The postcode of the building
- Whether the building will be occupied during the work
- Clear photographs of the problem areas

Common questions from Sidlesham clients
Is a smaller place like Sidlesham outside your area?
No. Places such as Sidlesham are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Is Enborne Business Park, near Sidlesham, within your area?
Yes. We cover Sidlesham and the area around it, including industrial estates, business parks and retail parks such as Enborne Business Park. A few photographs and the unit address let us price the work.
Which standards are fire seals tested to?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2. That rating only holds when the product is installed to its tested detail.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
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, and we reseal them to the specified detail.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. If others near Sidlesham need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
What we need from you
- Share your working hours and any access restrictions
- Tell staff and tenants when we’ll be in
- Clear stock, furniture or equipment away from the joints
