Hearnden Green questions
Do you work for landlords with property near Headcorn station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Hearnden Green?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
How long does fire rated sealant take?
A typical job takes a few hours for a handful of gaps, and longer for a whole building, including preparation and clearing up. Your quote will say how long we expect yours to take.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Do you certify the fire stopping?
We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and list the locations and products for you.
How we handle fire rated sealant in Hearnden Green
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That’s the part we focus on. We work on door frames, linear gaps and pipe & cable gaps, and common reasons people get in touch are seals cut through by electricians, plumbers or data installers and cracked or shrunken fire-rated sealant.
For a small place like Hearnden Green, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

How it works
On the day, there’s very little for you to do. Show us the job and we will 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 as small as Hearnden Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
Before we arrive
- Clear the area around the work
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Advice
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Tell trades working in the building that fire seals must be put back
- Check risers, ceiling voids and cupboards during building checks
- Report cracked or damaged seals as soon as you notice them
- Include fire stopping when you schedule refits
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.
Workplaces and buildings in Hearnden 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, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Around Hearnden Green, as everywhere, fire rated sealant is only as good as the preparation behind it. Letting a property close to Headcorn station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Issuing a fire rating or certificate for a building
- Construction that does not provide fire resistance on its own
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Landlord and commercial work in Hearnden Green
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
What happens if it’s left?
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. In a small place like Hearnden Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Surface by surface
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment room by room.
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.
