Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
About our fire stopping in Horndean
Facilities managers in Horndean often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. We work on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are seals that don’t match their tested detail and openings left by services added after handover. A single leaking joint is often how a building in Horndean first comes to us: we look at the rest while we are there and tell you what we find.
Towns the size of Horndean have plenty of buildings with compartment walls: schools, care homes, surgeries, offices and blocks of flats. Whenever new services go through those walls, the gaps need sealing with the specified product.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

What the job involves on each surface
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Writing the fire-stopping specification
- Construction that lacks the fire resistance the seal relies on
- Large openings beyond what any sealant detail covers
Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly before you book.
Surfaces we seal
- Linear gaps at wall heads
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers
From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Most work in Horndean is one building at a time: a school, a unit, an office or a block. We start with your photographs, drawings or a site visit, then send a fixed quote.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Agree which areas must stay open
- Tell us your opening times and when work is allowed
- Let building users know which areas are affected

Advice
How the quote is worked out
What shapes the price:
- How much existing material needs removing
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
- Backing rod, priming and other preparation
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 will price your job on its own details.
Details that help us quote
A good diagnosis starts with the right details. Let us know:
- How the joints are reached, and at what height
- Photos of the joints, close up and from further back
- Where the site is, with the postcode
- Any specification or named product
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Questions we are asked in Horndean
How does the move away from BS 476 affect penetration seals in Horndean?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Is Westfield Industrial Estate, near Horndean, within your area?
Yes. Estates, retail parks and business parks around Horndean, Westfield Industrial Estate among them, are all within reach. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure.
For managing agents and facilities managers
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Horndean can sit alongside others in a wider programme across Hampshire.
Fire-rated sealing for Horndean buildings
Horndean has three care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. Horndean is about 57 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
Halls and meeting rooms at places like Saint Wilfrid's sometimes gain new services, and any compartment wall crossed needs the specified seal. On a hospital site such as Havant War Memorial Hospital, which lies south of Horndean, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. On estates like Westfield Industrial Estate, 0.7 miles to the north-east of Horndean, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
