Fire Rated Sealant in Headstone
We cover Headstone for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly.
- Damaged fire sealant left by other trades
- Unsealed gaps where pipes and cables go through a wall
- Gaps where walls meet ceilings or slabs
How we handle fire rated sealant in Headstone
We often work from an action list drawn up by a fire risk assessor. If you share the list, we can quote for the gaps that need fire-rated sealant. We work on door frames, flats & HMOs and linear gaps, and common reasons people get in touch are unsealed gaps where pipes and cables go through a wall and damaged fire sealant left by other trades.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Headstone, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Big or small, it’s backed by our 12-month guarantee in Headstone and across Greater London.

Looking after it afterwards
After the cure time, these simple habits help:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Allow for resealing whenever new services are run
- Look in service cupboards and ceiling voids from time to time
- Report cracked or damaged seals as soon as you notice them
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a handful of gaps, and longer for a whole building. In a London area like Headstone, 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.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- Mention any tricky access
- Tell us if parking is tricky

Questions from Headstone
I let a flat near Headstone Lane station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is parking an issue for fire rated sealant in Headstone?
Parking in Headstone, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you certify the fire stopping?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it with a record of each location.
Where are you based?
We work from Crawley. We cover Headstone and the rest of Greater London, along with the rest of our area.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Can you quote for more than one area?
Yes. Just list everything you need and you will get one quote.
Commercial buildings in Headstone
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. 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.
As a London address, Headstone can be tricky for parking: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Pinner Park Primary School, fire-stopping around service openings should be restored whenever new services go in.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Different surfaces, different methods
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before we start to keep disruption down.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.

You’ll get a clear quote before we start. It’s based on:
- Whether old sealant or filler has to be cut out
- Whether the work is at height

- Working hours on commercial sites
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Before you ask for a quote, have a think about:
- The problem you’ve noticed
- Access, such as stairs, a lift or height
- Where the property is
- If it’s domestic, commercial or a hotel

What we are called out for in Headstone
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole round the new service isn’t always sealed again.
People generally contact us when they notice something like this:
- Damaged fire sealant left by other trades
- Door frames with gaps between frame and wall
- Fire seals that have cracked with movement
- Gaps where walls meet ceilings or slabs
If you let a flat or house near Headstone Lane station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
