When to call us in Cold Harbour
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
People generally contact us when they notice one of these:
- Open joints along the top of partitions
- Damaged fire sealant left by other trades
- Gaps around pipes and cables through fire-resisting walls
- Cracked or shrunken fire-rated sealant
Letting a property close to Wargrave station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Fire rated sealant in Cold Harbour, done properly
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, gap by gap. Typical jobs include ordinary sealant used where a fire-rated product was needed and joints picked up in a fire-stopping survey, on pipe & cable gaps, plasterboard & masonry and linear gaps.
If you have holiday lets, a converted barn used for business or a community building near Cold Harbour, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Aftercare tips
To keep the joints looking good and working properly:
- Store the list of sealed gaps with your building paperwork
- Allow for resealing whenever new services are run
- Check whether a sealant can be painted before decorating over it
- Keep photos of seals that will be hidden
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is normally a straightforward job.
Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a handful of gaps, and longer for a whole building, depending on how much there is to do. In a small place like Cold Harbour, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.

- We hand over a list of locations and products for your records.

Fire rated sealant in Cold Harbour: local notes
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as Saint Peter, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as Knowl Hill Church of England Primary Academy are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

Different surfaces, different methods
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified.
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
