Fire-rated sealant in Nash Street, Kent
Fire-stopping gaps in Nash Street need attention? We remove the old material, prepare the joints and seal them properly.
- Linear gaps at the head of walls
- Seals cut through by electricians, plumbers or data installers
- Gaps flagged on a fire risk assessment
Fire rated sealant for homes and businesses in Nash Street
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on plasterboard & masonry, linear gaps and pipe & cable gaps, and the jobs we see most are gaps flagged on a fire risk assessment and open gaps behind door architraves.
If you have holiday lets, a converted barn used for business or a community building near Nash Street, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Each job carries a 12-month guarantee.

When to call us in Nash Street
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
The most common problems we see are:
- Open joints along the top of partitions
- Seals cut through by electricians, plumbers or data installers
- Open gaps behind door architraves
- Ordinary sealant used where a fire-rated product was needed
Managing a site like Istead Rise Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.
Questions to ask before booking
- Whether you can choose the colour
- Whether the sealant suits the joint
- Who turns up on the day
- What preparation is included
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Include hidden areas like risers in routine checks
- Take photos of fire stopping before ceilings or boxing go back
- Tell trades working in the building that fire seals must be put back
- Flag any open gap you spot round a pipe or cable
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
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.

When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Deciding what fire stopping a building needs
- Large holes that need a different fire-stopping system
- Sign-off of the building, which sits with building control or your assessor
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

Fire rated sealant in Nash Street: local notes
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
If you look after a church, hall or community building such as Church of St Mildred, older buildings that have had new heating or wiring often have service gaps worth checking. Rented homes near Meopham station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What happens if it’s left?
A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Older cottages and farmhouses around Nash Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.
