Common problems we fix in Old Netley
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.
Any of these means the joints need attention:
- Open holes round services passing through fire walls
- Fire stopping disturbed by later work
- Ordinary sealant used where a fire-rated product was needed
- Holes left by a change of layout
If you look after a church, hall or community building such as St Paul’s Church, gaps around pipes and cables are worth checking after any building work there.

Fire rated sealant in Old Netley, done properly
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That’s the part we focus on, one gap at a time. If you’re dealing with gaps around pipes and cables through fire-resisting walls and damaged fire sealant left by other trades, we can put it right.
If you have holiday lets, a converted barn used for business or a community building near Old Netley, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Why it’s worth doing now in Old Netley
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Where a wall is exposed, as many are in small places like Old Netley, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Problems with the door itself rather than the gap around the frame
- Assessing a building’s fire safety
- Construction that doesn’t provide fire resistance on its own
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
What we seal
- Door frames
- Plasterboard & masonry
- Service penetrations
- Pipe & cable gaps
- Flats & HMOs
- Linear gaps
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What we do, step by step
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Old Netley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property

What the job involves on each surface
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail.
