Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Croxley Green, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
How to prepare
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

Advice
Signs you need fire rated sealant in Croxley Green
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
Look out for these signs:
- Holes left by a change of layout
- Seals cut through by electricians, plumbers or data installers
- Unsealed gaps around fire door frames
- Ordinary sealant used where a fire-rated product was needed
Schools such as Harvey Road Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

Workplaces and buildings in Croxley Green
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, 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.
Rented homes near Rickmansworth station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as St Oswald's Parish Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Will you come out to Croxley Green?
Yes, Croxley Green is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you work in occupied buildings?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use, with access planned around residents or staff. Out-of-hours work can be arranged if that suits the building.
Can I add another job to the visit?

How long does fire rated sealant take?
Typically it takes a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer, and we will tell you how long to expect.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
When something else is needed
In fairness, there are a few things sealant will not fix:
- Deciding what fire stopping a building needs
- Walls or floors that weren’t built to resist fire
- Openings too large for sealant, which need batts, boards or another system
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
