Why it’s worth doing now in Heston
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. 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 for homes in Heston.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why Heston clients choose us
- Any old sealant cut out fully, not covered over
- An ARBOMaster approved applicator
- Homes, businesses and hotels
- Tidy, careful work

What affects the cost of fire rated sealant
We quote each job individually. This is what makes a difference:
- The old material and how stubborn it is
- Access and height
- Working hours on commercial sites
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
When you contact us, it’s useful to know:
- Any access issues, like height or stairs
- What’s wrong with the joints now
- Where the job is, and your postcode
- Whether it’s a home or a business
To get a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. You will have a clear quote before work begins.
Aftercare tips
To keep the joints looking good and working properly:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Check risers, ceiling voids and cupboards during building checks
- Tell trades working in the building that fire seals must be put back
- Report cracked or damaged seals as soon as you notice them
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
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.
Heston: your questions answered
Do you work for landlords with property near Southall station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Do you work for hotels and guest houses in Heston?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first.
Do you cover Heston?
Yes. We work in Heston. For a quote, phone 0345 464 0079 or email us.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Are you fully insured?
Yes. We are fully insured.
When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- Problems with the door itself rather than the gap around the frame
- Fire risk assessments, which need a qualified assessor
- Big openings where sealant alone is not the tested solution
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.
Where we work in Heston
- Service penetrations
- Linear gaps
- Pipe & cable gaps
- Plasterboard & masonry
- Door frames
- Flats & HMOs
Surface by surface
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard for each gap size.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.

What we do, step by step
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- 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.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- Mention any tricky access

Can I do it myself?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Fire rated sealant around Heston
Heston has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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 are given, installing the product to its tested details.
If you look after a church, hall or community building such as St Leonard's Church, service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as Westbrook Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Letting a property close to Southall station? Then any gap left by new services in shared walls should be closed with a fire-rated product.
