Fire stopping for businesses in Batford
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What sets the cost
Quotes vary with the job. Expect it to depend on:
- Working within restricted access windows
- Quantities, in metres or numbers
- Backing rod, priming and other preparation
- Location, for remote and island sites
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
Whether it’s one area or a whole building, these details speed things up:
- Anything awkward about access or site hours
- Clear photographs of the problem areas
- Your programme or deadline
- The postcode of the building
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.
About our fire stopping in Batford
Facilities managers in Batford often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. Most enquiries involve fire-rated sealant that has cracked or shrunk back and head-of-wall gaps with no fire seal, on service gaps in risers, linear gaps at wall heads and cable penetrations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Batford, that means joint design, primers and backing rod as standard.
Buildings in a smaller place such as Batford that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

FAQs: Batford
Can you work on a hospital site such as Harpenden Memorial Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work at a site such as Southdown Industrial Estate, by Batford?
Yes, sites like Southdown Industrial Estate are within our area, along with the rest of Batford. 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.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What does an EI 60 rating mean?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. That rating only holds when the product is installed to its tested detail.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you design or specify fire stopping?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is installing what they specify, to the product’s tested detail.
When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
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 any cutting starts, with the work itself usually taking a single visit for a short list of penetrations, or a phased programme for a whole building. Several jobs near Batford can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Arrange parking or a loading space
- Agree which areas must stay open
- Flag any permit to work we’ll need

Advice
Common problems we fix in Batford
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.
These are often picked up first by site or facilities staff:
- Damaged fire seals in risers and voids
- Expanding foam used as fire stopping
- Snag lists that include open service penetrations
- Unsealed joints where partitions meet the slab
Hospital estates such as Harpenden Memorial Hospital (0.6 miles west of Batford) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
What to look for in a quote
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- What site paperwork they can supply
- How long is the guarantee, and what does it include?
- Will CSCS-carded applicators be on site?

What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Fire doors, dampers or other fire safety equipment
- Writing the fire-stopping specification
- Approving the work on behalf of building control
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we’ll tell you honestly.
Surfaces we seal
- Service gaps in risers
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Cable penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
Surface by surface
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits.
