Copnor: your questions answered
Do you work for landlords with property near Fratton station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Do you work in hotels near Copnor?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can I use normal mastic around a pipe through a fire wall?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. We cut it out and reseal with a fire-rated product.
Can I add another job to the visit?
Yes. Just list everything you need.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Will you assess my building’s fire safety?
No. We follow the requirements from your assessor, designer or building control.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
How we handle fire rated sealant in Copnor
We can work through a building room by room or floor by floor, with each location and product recorded. It gives you a list to keep with the building’s fire safety documents. Typical jobs include unsealed gaps where pipes and cables go through a wall and standard silicone or caulk in a fire-stopping gap, on service penetrations, pipe & cable gaps and door frames.
Commercial work around a smaller place like Copnor usually means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Common problems we fix in Copnor
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
Signs it’s time to call us include:
- Fire seals that have cracked with movement
- Open gaps behind door architraves
- Standard silicone or caulk in a fire-stopping gap
- Sealant items on a fire risk assessment action list
If you look after a church, hall or community building such as Church of St Alban, service openings in its walls need the right fire-rated sealant, as in any building.

Different surfaces, different methods
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.
Flats and HMOs
Conversions generally leave a mix of old and new service holes. We seal the ones on your specification with a tested product and record where they are.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Walls or floors that weren’t built to resist fire
- Big openings where sealant alone isn’t the tested solution
- Deciding what fire stopping a building needs
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Why it’s worth doing now in Copnor
Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own. In an older home around Copnor, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.
