When to call us in Hanwell
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
Any of these means the joints need attention:
- Gaps left after a refit or conversion
- Gaps around pipes and cables through fire-resisting walls
- Fire seals that have cracked with movement
- Standard silicone or caulk in a fire-stopping gap
As a London address, Hanwell can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Fire rated sealant for homes and businesses in Hanwell
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We’re often asked to deal with cracked or shrunken fire-rated sealant and gaps around pipes and cables through fire-resisting walls, on service penetrations, flats & HMOs and linear gaps.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Hanwell, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

What else we do in Hanwell
Common questions in Hanwell
I let a flat near Hanwell station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do you work in hotels near Hanwell?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you seal over the old sealant?
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.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or email us.
What does intumescent mean?
Intumescent means it swells when heated. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
How the job changes by surface
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before any work starts to keep disruption down.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
What affects the quote in Hanwell
The quote reflects the job in front of us. We look at:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- Any working-time requirements on site
- How easy the joints are to reach
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
For a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Check risers, ceiling voids and cupboards during building checks
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Flag any open gap you spot round a pipe or cable
- File the fire-stopping record where your assessor can find it
Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.
The process
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In Hanwell, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the gap cleaned.
- 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.
How to prepare
- Tell us if parking is tricky
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work
How to get a quote

Why deal with it now?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.
What you get with us
- Arbo and Everbuild products
- Tidy, careful work
- Homes, businesses and hotels
- An ARBOMaster approved applicator
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Workplaces and buildings in Hanwell
Hanwell 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. 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’re given, installing the product to its tested details.
If you look after a church, hall or community building such as Church of St Mellitus, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as St Joseph's Catholic Primary School, fire-stopping around service openings should be restored whenever new services go in.
