Elstree Fire Rated Sealant
Professional fire rated sealant in and around Elstree, with every bit of old sealant taken out first.
- Gaps filled with a product that is not fire-rated
- Gaps left after a refit or conversion
- Seals cut through by electricians, plumbers or data installers
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Fire risk assessments, which need a qualified assessor
- Doors that are not fire doors in the first place
- Openings too large for sealant, which need batts, boards or another system
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Flats & HMOs
- Pipe & cable gaps
- Plasterboard & masonry
- Service penetrations
- Door frames
- Linear gaps
How we handle fire rated sealant in Elstree
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. If you are dealing with gaps left after a refit or conversion and unsealed gaps around fire door frames, we can put it right, whatever the surface.
Somewhere as small as Elstree, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
All of our work is guaranteed for twelve months.

How it works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for a handful of gaps, and longer for a whole building from start to finish. Somewhere like Elstree needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks

Why it’s worth doing now in Elstree
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Around Elstree, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

Elstree questions
Is Elstree within the area you cover?
Yes. Elstree 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.
Do you cover Elstree for fire rated sealant?
Yes, Elstree is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Where are you based?

Can you work in occupied buildings?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use. Out-of-hours work can be arranged if that suits the building.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. The specification and the tested detail decide which is used.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Fire rated sealant in Elstree: 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.
Community buildings like Church of St Nicholas are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you look after a building such as St Nicholas Elstree Church of England VA Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
