Fire rated sealant around Harbledown
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. There are hotels and other places to stay in and around Harbledown. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
If you let a flat or house near Canterbury West station, 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 Michael and All Angels Church, gaps around pipes and cables are worth checking after any building work there.

What happens if it’s left?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Where a wall is exposed, as many are in small places like Harbledown, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Common problems we fix in Harbledown
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
Keep an eye out for any of the following:
- Fire stopping disturbed by later work
- Gaps left after a refit or conversion
- Unsealed gaps around fire door frames
- Linear gaps at the head of walls
For site and facilities teams at buildings such as The Canterbury Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
Before booking anyone

The process
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Harbledown, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your files.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints

Advice
When something else is needed

Questions from Harbledown
Do you work in hotels near Harbledown?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Is Harbledown within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you fill the gap behind a fire door frame?
Yes, if the gap is within the product’s tested range. Our work is the gap around the frame and we will tell you if we spot problems with the door.
Will you assess my building’s fire safety?
No, assessment isn’t something we do. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.
Do you certify the fire stopping?
That isn’t something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it with a record of each location.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Quotes for fire rated sealant in Harbledown
Your quote is based on your job. We look at:
- Whether there’s mould to deal with
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- The type of property
- The problem you’ve noticed
- How many joints, rooms or windows are involved
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Ask which product was used before you paint
- File the fire-stopping record where your assessor can find it
- Get damaged fire seals looked at promptly
- Make resealing part of every contractor’s brief
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
