About our fire rated sealant in Cranmore
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. We’re often asked to deal with unsealed gaps around fire door frames and fire stopping disturbed by later work, across pipe & cable gaps, door frames and linear gaps.
If you have holiday lets, a converted barn used for business or a community building near Cranmore, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of gaps, and longer for a whole building.

Everything for the job comes with us, so a second trip is avoided where possible.

Advice
Surface by surface
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the sealant bonds.
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.
Why deal with it now?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. In a small place like Cranmore, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

Fire rated sealant in Cranmore: local notes
If you run a hotel, guest house or holiday let in a coastal place like Cranmore, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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 work to the specification you are given, installing the product to its tested details.
Letting a property close to Lymington Pier station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Managing a site like Shalfleet Church of England Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
How to look after the new joints
To keep the joints looking good and working properly:
- Ask every contractor to reseal any fire stopping they disturb
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Allow for resealing whenever new services are run
- Take photos of fire stopping before ceilings or boxing go back
Do not drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
