Fire stopping in Lagness
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Doing it in-house
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.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
How we handle fire stopping in Lagness
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal, not a rule of thumb. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are builders’ foam or ordinary silicone in compartment walls and damaged fire seals in risers and voids. A single leaking joint is often how a building in Lagness first comes to us: we look at the rest while we are there and tell you what we find.
A job near Lagness is typically planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

What else we do in Lagness
Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Report damaged or disturbed seals as soon as they’re spotted
- Agree the fire-stopping specification before services go in
- Get seals inspected before ceilings and boxing close
- Look above ceilings when tiles are lifted for other jobs
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts.
Building owners, agents and FMs in Lagness
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
Diagnose, treat, sign off
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. If others near Lagness 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.
- Access, permits and the order of areas are agreed with the site team.
- 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.
Preparing the site
- Let building users know which areas are affected
- Point out parking and an unloading spot
- Let us know about inductions and permits

Advice
Signs you need fire stopping in Lagness
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
Look out for the following:
- Unsealed joints where partitions meet the slab
- Fire-rated sealant that has cracked or shrunk back
- Service penetrations left open after M&E works
- Unsealed penetrations discovered above suspended ceilings
On estates like Quarry Lane Industrial Estate (2.4 miles north-west of Lagness), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
What your quote should include
- What level of public liability insurance do they hold?
- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
- Their pre-qualification and accreditations
Fire-rated sealing for Lagness buildings
Central London is about 56 miles from Lagness. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. The 2 miles around Lagness include two care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
Residences at universities like University of Chichester (1.3 miles north of Lagness) have compartment walls that must be resealed whenever services change. For a unit at a centre such as Arun Retail Park, 2.7 miles to the east of Lagness, penetration seals are worth checking after each shop fit.

Your questions answered
Would you work within a site like Bognor Regis War Memorial Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Will you plan work around the academic year at somewhere like University of Chichester?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you fire stop behind the services contractors?
Yes. Send the schedule or marked-up drawings and the specified product details for a fixed quote. We can follow the services contractor floor by floor so areas aren’t left open.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
What changes on 2 September 2029?
In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029, subject to the Government’s transitional arrangements. After that, the European classification under BS EN 13501-2 is the route. Product selection stays with your designer.
When it isn’t the sealant
Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:
- Walls or floors that aren’t fire-resisting to begin with
- Large openings beyond what any sealant detail covers
- Issuing fire ratings or certificates for seals
If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.
What we seal
