Fire stopping in Wiston
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Fire stopping in Wiston, done properly
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. We work on linear gaps at wall heads, service gaps in risers and pipe penetrations, and the usual reasons a site gets in touch are openings left by services added after handover and open linear gaps along the top of fire-resisting walls. A single leaking joint is often how a building in Wiston first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a smaller site near Wiston, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Work we carry out in West Sussex comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email drawings and photos and we will arrange a return visit.

What happens if it’s left?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. For buildings around smaller places like Wiston, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Take a look at what affects the cost and our accreditations.
Doing it in-house
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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Common questions from Wiston clients
Do you cover business parks and estates near Wiston, such as Rock Business Park?
Yes, sites like Rock Business Park are within our area, along with the rest of Wiston. Send details of the unit and the work through our quote form for a quick quote.
Is Wiston too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Is the work guaranteed?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
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.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Is fire stopping in Scotland covered by different guidance?
Our area runs from Greater London and the South East to every part of Scotland. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, with proprietary products tested for the end use.
What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Fire doors, dampers or other fire safety equipment
- Large openings beyond what any sealant detail covers
- Gaps in walls that were never built as compartment walls
If you are not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer before you book.
What we seal
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Linear gaps at wall heads
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Cable penetrations
On site: what to expect
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Rural sites near Wiston may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Send your site hours and access windows
- Arrange parking or a loading space
- Let building users know which areas are affected
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Surface by surface
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area, and note anything we find that isn’t on it.

What we’re called out for in Wiston
Physical damage is another reason seals stop doing their job. 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.
What tends to prompt an enquiry:
- Open linear gaps along the top of fire-resisting walls
- Fire-rated sealant that has cracked or shrunk back
- Unsealed penetrations discovered above suspended ceilings
- Service penetrations left open after M&E works
Office fit-outs on sites such as Rock Business Park, 1.1 miles to the west of Wiston, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.
