Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. West Heath can form part of a wider programme across Hampshire.
Fire stopping for commercial buildings in West Heath
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. The enquiries we see most involve unsealed joints where partitions meet the slab and snag lists that include open service penetrations, across small duct penetrations where the tested detail allows, linear gaps at wall heads and joints between fire-resisting walls and floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in West Heath, that means joint design, primers and backing rod as standard.
Barn and farm-building conversions near places like West Heath often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

How the quote is worked out
The price varies from site to site. Expect it to depend on:
- Quantities, in metres or numbers
- The size and state of each joint
- Whether old sealant has to be cut out first
- Travel to remote or island sites
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- Specification clauses that apply
- Anything awkward about access or site hours
- The postcode of the building
- Asbestos survey details if the building is older

Common problems we fix in West Heath
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
If one of these sounds familiar, it’s time for a closer look:
- Openings found when ceilings come down for a refit
- Fire-stopping items raised at inspection or handover
- Service penetrations left open after M&E works
- Seals disturbed by maintenance and left open
Schools such as The Priory Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

When to bring in a specialist
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.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Looking after the joints
Regular inspection catches problems early. In particular:
- Check with the data sheet before painting over fire sealant
- Agree the fire-stopping specification before services go in
- Brief every trade that openings they make must be sealed
- Keep general-purpose fillers away from compartment walls
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
