Fire rated sealant in Lower Denford
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you are dealing with damaged fire sealant left by other trades and open holes round services passing through fire walls, we can put it right, on plasterboard & masonry, pipe & cable gaps and linear gaps alike.
For holiday lets, converted business premises or a community building near Lower Denford, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Big or small, you get the same 12-month guarantee.

Other services in Lower Denford
Keeping the joints in good condition
After the cure time, these simple habits help:
- Check risers, ceiling voids and cupboards during building checks
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Allow for resealing whenever new services are run
- File the fire-stopping record where your assessor can find it
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
Should I try it myself first?
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. Everything old must be removed first.
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 does not work out, we can still put it right.

Workplaces and buildings in Lower Denford
Lower Denford has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.
If you look after a building such as Hungerford Primary School, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Hungerford Methodist Church, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Hungerford station, any gap left by new services in shared walls should be closed with a fire-rated product.

What the job involves on each surface
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Certifying a building or signing off its fire safety
- Large holes that need a different fire-stopping system
- Doors that are not fire doors in the first place
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
