Fire Rated Sealant in Harrow Weald
Our applicators work in Harrow Weald on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly.
- Cracked or shrunken fire-rated sealant
- Fire stopping disturbed by later work
- Gaps around pipes and cables through fire-resisting walls
Fire rated sealant in Harrow Weald, done properly
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you’re dealing with gaps left after a refit or conversion and fire stopping disturbed by later work, we can put it right, whatever the surface.
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. Where a building in Harrow Weald needs to stay open, work can be planned outside normal hours.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Harrow Weald, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed

Different surfaces, different methods
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail and we flag any that need another system.
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Construction that does not provide fire resistance on its own
- Openings too large for sealant, which need batts, boards or another system
- Doors that are not fire doors in the first place
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

Common questions in Harrow Weald
Do you work for landlords with property near Headstone Lane station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Is parking a problem for a job in Harrow Weald?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can ordinary silicone be used in a fire-stopping gap?
No. Standard sealants are not made or tested to stop fire. If it’s been used, we remove it and use the right product.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.

What fire rated sealant looks like in Harrow Weald
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. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
For buildings such as St Michael & All Angels, service openings in its walls need the right fire-rated sealant, as in any building. For landlords with property near Headstone Lane station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Why it’s worth doing now in Harrow Weald
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Harrow Weald, the repair is bigger than the sealant job would have been.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Flag any open gap you spot round a pipe or cable
- Store the list of sealed gaps with your building paperwork
- Look in service cupboards and ceiling voids from time to time
- Keep photos of seals that will be hidden
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.
An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
