Fire stopping in Gosport
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Site teams most often ask us about expanding foam used as fire stopping and fire-stopping items raised at inspection or handover, on pipe penetrations, linear gaps at wall heads and cable penetrations. Most enquiries from Gosport 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.
Towns the size of Gosport have plenty of buildings with compartment walls: schools, care homes, surgeries, offices and blocks of flats. Whenever new services go through those walls, the gaps need sealing with the specified product.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Honest limits
Before quoting, we check that sealant is the right answer. It won’t put right:
- Issuing fire ratings or certificates for seals
- Fire risk assessments, a job for a competent assessor
- Plastic pipes whose detail calls for a collar or wrap

Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Commercial clients in Gosport
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Gosport can sit alongside others in a wider programme.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
What we’re called out for in Gosport
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
Most enquiries start with one or more of the following:
- Open linear gaps along the top of fire-resisting walls
- Seals disturbed by maintenance and left open
- Fire stopping installed outside its tested range
- Expanding foam used as fire stopping
For an estates team at a campus like University of Portsmouth - North Zone, which lies east of Gosport, summer M&E works are normally followed by a round of penetration sealing.

Advice
Quoting for work in Gosport
Quotes vary with the job. Expect it to depend on:
- Quantities, in metres or numbers
- Distance, for remote addresses
- Removal of failed or old sealant
- The product specified
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:
- Any specification or named product
- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
- Any dates the work must fit around
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or email us.
Gosport: questions and answers
How does the move away from BS 476 affect penetration seals in Gosport?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can work at a site such as University of Portsmouth - North Zone fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What will the job cost?
We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
