Fire stopping in Wilmington, done properly
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow. If you have openings left by services added after handover and expanding foam used as fire stopping, we can help, on linear gaps at wall heads, small duct penetrations where the tested detail allows and cable penetrations alike. Most enquiries from Wilmington start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For a smaller site near Wilmington, 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.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Common questions from Wilmington clients
Is Wilmington 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.
Does your area include sites such as Dartford Heath Retail Park, near Wilmington?
Yes. Our area takes in Wilmington and its surroundings, with estates and business parks such as Dartford Heath Retail Park included. A few photographs and the unit address let us price the work.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Is the BS 476 change in 2029 relevant to fire stopping?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, though transitional rules apply. Scotland follows its own Technical Handbook, including clause 2.1.14 on service penetrations.
Can you tell us what fire stopping our building needs?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements, and tell you if a detail needs another product.
Do you approve fire stopping for building control?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.
Can you reseal penetrations after our M&E works?
Yes, provided a specification covers them. New services after M&E works often breach existing seals, and we reseal them to the specified detail.
Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Wilmington are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Move anything stored against the joints
- Confirm the product named in the specification
- Warn occupants and staff about the work

Advice
Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What affects the price in Wilmington
A fixed quote reflects the actual work. It takes account of:
- Whether old sealant has to be cut out first
- Backing rod, priming and other preparation
- The product specified
- Working within restricted access windows
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
- The site address and postcode
- When you need the work done
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, call the office on 01277 525 020 or email the details over.
Different surfaces, different methods
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do and we will tell you what the detail says instead.
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, along the full length of the run.
Why act early in Wilmington
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach. Converted and older buildings near places like Wilmington tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
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.
Why appoint us
- Failed material removed, not covered up
- Public liability insurance in place
- One number for every site we cover
- Specification-led, product-correct work

Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Check with the data sheet before painting over fire sealant
- Record which product was used where
- Ask the designer to confirm details early on refits
- Include service cupboards in routine inspections
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.
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, not months later.
Compartment walls and floors in Wilmington
Wilmington lies roughly 13 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. The area within 2 miles of Wilmington holds a number of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.
Shop fits on retail sites such as Dartford Heath Retail Park, 0.8 miles to the north-east of Wilmington, can bring new services through fire-resisting walls between units, to be sealed with the specified product. For a hospital such as Little Brook Hospital, which lies north-east of Wilmington, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. Hotels like Rowhill Grange Hotel & Utopia Spa (to the south of Wilmington) are refurbished in phases, and each phase can open up compartment walls.
Wilmington is about 2 miles south-west of Dartford, in Kent. Commercial clients in Wilmington can call on us for service penetrations, as part of our coverage of Kent. 931 places across Kent fall within our area, Wilmington among them.
