Commercial clients in Portfield
Building owners and managing agents use us on everything from one building to a spread of sites around Portfield. Several sites can go on one quote, which keeps the paperwork simple.

How we handle fire stopping in Portfield
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, give us a call on 01277 525 020 or send details through our quote form with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. The enquiries we see most involve old intumescent sealant that has split away and fire stopping installed outside its tested range, across joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and pipe penetrations. A single leaking joint is often how a building in Portfield first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Portfield, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Penetration seals near Portfield
There are three care or nursing homes within about 2 miles of Portfield. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. There are several hotels within about 2 miles of Portfield. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
For a site team at a college like Chichester College, 1.2 miles to the west of Portfield, fire-rated sealing is best scheduled after the summer works. At a university such as University of Chichester, 0.8 miles to the north-west of Portfield, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Large healthcare estates like St Richard's Hospital (0.6 miles north-west of Portfield) change their services often, so penetration seals are worth checking after M&E work.

What sealant work can’t fix
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Large openings beyond what any sealant detail covers
- Walls or floors that aren’t fire-resisting to begin with
- Fire risk assessments, a job for a competent assessor
If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
What we seal
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
Why it’s worth doing now in Portfield
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
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.
What you get with us
- Fixed quotes based on photographs, drawings or a visit

Questions about Portfield
Is hospital work, at somewhere like St Richard's Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Portfield off your patch?
Not at all. Portfield 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.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can you seal any opening with fire-rated sealant?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards.
What changes on 2 September 2029?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, subject to transitional arrangements. In Scotland, the Technical Handbook sets its own guidance, including clause 2.1.14 on service penetrations.
Do you approve fire stopping for building control?
No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Work in places the size of Portfield is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- 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.
- 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
- Tell staff and tenants when we will be in
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand

Surface by surface
Small ducts
Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.
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.
Quoting for work in Portfield
