Fire rated sealant in Keston, done properly
We do not assess buildings or decide what fire stopping is needed; 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 seals cut through by electricians, plumbers or data installers and holes left by a change of layout, on flats & HMOs, plasterboard & masonry and pipe & cable gaps.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Keston cannot close.
Big or small, you get the same 12-month guarantee in Keston and across Greater London.

What happens if it’s left?
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

What sealant work can’t fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Large holes that need a different fire-stopping system
- Assessing a building’s fire safety
- Sign-off of the building, which sits with building control or your assessor
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Your questions about fire rated sealant in Keston
Can parking be tricky for a visit in Keston?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you cover Keston for fire rated sealant?
Yes, Keston is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you work in occupied buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
For anyone letting property in or around Keston, several properties can go on one quote. Send us the addresses and the work at each, and pictures by email help.
Fire rated sealant around Keston
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
Community buildings like Keston Parish Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Schools such as Keston Church of England Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Hayes (Kent) station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Surface by surface
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before the sealant goes in.
What affects the cost of fire rated sealant
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- Access and height
- How much there is to do
- When we can work, for business premises
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
Asking for a quote
When you call or email, these details help:
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- If someone has resealed it before
- Pictures of the joints, sent by email
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
What happens on the day
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In a London area like Keston, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on
