Fire stopping for commercial buildings in Copnor
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, phone 01277 525 020 or email drawings and photos with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. If you’re dealing with unsealed joints where partitions meet the slab and fire-rated sealant that has cracked or shrunk back, we can put it right. Most enquiries from Copnor 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 smaller places like Copnor, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Why it’s worth doing now in Copnor
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. For buildings in places like Copnor, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

How the job changes by surface
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.
Plastic pipes
Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough, and we won’t substitute it for a specified collar.
Compartments and services around Copnor
At about 63 miles from central London, Copnor is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. There are a good number of hotels within about 2 miles of Copnor. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
Hotels such as The Avenue Hotel (1.2 miles north-west of Copnor) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. For a site team at a college like Portsmouth College, 0.8 miles to the east of Copnor, fire-rated sealing is best scheduled after the summer works.

What else we do in Copnor
When to call us in Copnor
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.
Clients usually get in touch after noticing one or more of the following:
- Fire-rated sealant that has cracked or shrunk back
- Fire seals cut back for extra cables and never reinstated
- Service penetrations left open after M&E works
- Snag lists that include open service penetrations
On a hospital site such as St James Hospital (1.3 miles south-east of Copnor), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
What your quote should include
- What the guarantee covers, and for how long
- Their plan for phasing and protecting the area
- Will failed sealant be removed rather than covered?
- Are they CHAS accredited or on Constructionline?
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
FAQs: Copnor
Will you plan work around the academic year at somewhere like University of Portsmouth?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Would you work within a site like St James Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you work in Scotland as well as England?
Scotland sets its own building regulations, with Technical Handbooks, while England relies on Approved Document B. Wherever the site is, our work follows the specification and the tested detail.
Can you seal any opening with fire-rated sealant?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. If an opening falls outside, it needs another solution, specified by your designer.
From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. What matters most for a job in Copnor is a clear list of what needs doing. You will then get a fixed price for the work.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you

- Agree which areas must stay open

Advice
Doing it in-house
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.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
