Fire stopping for commercial buildings in Warsash
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Warsash and nearby. If you have penetration schedules that need working through and fire sealant pulled out of the opening, we can put it right. Most enquiries from Warsash start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around Warsash, penetration and linear seals tend to be one-building jobs. Send the specification, drawings or photographs of the openings and we will quote to suit.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Signs you need fire stopping in Warsash
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access normally bring them to light.
If one of these sounds familiar, it’s time for a closer look:
- Builders’ foam or ordinary silicone in compartment walls
- Hidden openings found during inspections
- Fire seals cut back for extra cables and never reinstated
- Penetration schedules that need working through
Schools such as Hook-With-Warsash Church of England Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

What else we do in Warsash
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Surface by surface
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones typically call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any outside it are raised with you.
What happens if it’s left?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. In a smaller place such as Warsash, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Questions we’re asked in Warsash
Is a hospital such as Fareham Community Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is Warsash too far out for you?
Not at all. Warsash is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will you sign off the seals for us?
No. Approval sits with the designer, principal designer or building control. We’ll confirm the products and details used and agree any further records when we quote.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Will you write the fire-stopping specification?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements and point out anything needing another product.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. Work in places the size of Warsash 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 raise any questions before we price.
- 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.
- 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.
Preparing the site
- Explain the parking and delivery arrangements
- Confirm the product named in the specification
- Clear stock, furniture or equipment away from the joints

Compartment walls and floors in Warsash
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Warsash is about 68 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
In a building such as Church of St Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail. On a hospital site such as Fareham Community Hospital, which lies north-east of Warsash, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
