How the job changes by surface
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before any work starts so residents know what to expect.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the sealant bonds.
Fire rated sealant for homes and businesses in Hadham Cross
Deciding which gaps need fire stopping is not our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We’re often asked to deal with gaps filled with a product that isn’t fire-rated and damaged fire sealant left by other trades, on door frames, pipe & cable gaps and service penetrations.
For holiday lets, converted business premises or a community building near Hadham Cross, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
You get a 12-month guarantee, the same in Hadham Cross as everywhere else we work.

When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Large holes that need a different fire-stopping system
- Construction that does not provide fire resistance on its own
- Sign-off of the building, which sits with building control or your assessor
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.

What else we do in Hadham Cross

- Linear gaps at the head of walls
- Open holes round services passing through fire walls
- Old fire sealant that has split or come away
- Gaps flagged on a fire risk assessment

Workplaces and buildings in Hadham Cross
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’re given, installing the product to its tested details.
For buildings such as Church of St Thomas, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as St Andrew's CofE Primary School and Nursery are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Common questions in Hadham Cross
Is Hadham Cross within the area you cover?
Yes. Hadham Cross is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Hadham Cross in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Hadham Cross is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected.
Will you assess my building’s fire safety?
No. We work from the specification you give us and install to the manufacturer’s details.
How long will you be here?
A typical job takes from a few hours to a few days, depending on the number of gaps and the access, including the preparation. We will confirm how long when we quote.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Can you fill the gap behind a fire door frame?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame, and we’ll mention anything we notice about the door.
For landlords and businesses
We also work for property managers and facilities teams in Hadham Cross and across Hertfordshire. We can quote a run of properties together, and we are fully insured.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
