About our fire stopping in Little Heath
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 rather than guesswork. If you have non-fire-rated filler around services and openings left by services added after handover, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Little Heath is the same: the right product in a properly prepared joint.
In places the size of Little Heath, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Deciding what a wall or floor needs, which belongs to the designer
- Construction that lacks the fire resistance the seal relies on
- Large openings beyond what any sealant detail covers
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think.
What we seal
- Service gaps in risers
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Linear gaps at wall heads
On site: what to expect
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Work in places the size of Little Heath is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- 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.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use
- Warn occupants and staff about the work

Advice
What we’re called out for in Little Heath
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
Common reasons buildings call us in:
- Fire seals cut back for extra cables and never reinstated
- Old intumescent sealant that has split away
- Service penetrations left open after M&E works
- Non-fire-rated filler around services
Colleges such as Integration College, 1 mile south of Little Heath, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
What to look for in a quote
- How long is the guarantee, and what does it include?

- What site paperwork they can supply
- How joint depth will be controlled
How the job changes by surface
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail.
Should maintenance staff do it?
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.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Penetration seals near Little Heath
Little Heath is about 41 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
Campus buildings at universities such as University of Reading, 4.1 miles east of Little Heath, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Tenant changes at parks like Turnhams Green Business Park (1.1 miles south of Little Heath) bring new data and services, and openings through fire-resisting walls need the specified seal.

Cost factors for service penetrations
The price varies from site to site. It mainly depends on:
- Site requirements such as inductions and permits
- How accessible the joints are
- Quantities, in metres or numbers
- Whether the work must be split into stages
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What we need to price the job
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Photos of the joints, close up and from further back
- Anything awkward about access or site hours
- Drawings or a marked-up plan, if available
- Whether the building will be occupied during the work
