Avery Hill Fire Rated Sealant
We cover Avery Hill for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly.

- Sealant items on a fire risk assessment action list
Honest limits
Sealant is not the answer to every problem, and we will tell you before work begins. Sealant won’t put right:
- Fire doors that need new seals, closers or hardware
- Big openings where sealant alone isn’t the tested solution
- Deciding what fire stopping a building needs
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.
Surfaces we seal
- Service penetrations
- Door frames
- Plasterboard & masonry
- Pipe & cable gaps
- Flats & HMOs
- Linear gaps
About our fire rated sealant in Avery Hill
Bigger jobs can be worked through in stages, flat by flat or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. We work on flats & HMOs, door frames and plasterboard & masonry, and people most often call us about door frames with gaps between frame and wall and linear gaps at the head of walls.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Avery Hill, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How the job changes by surface
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the seal has something sound to bond to.
Commercial buildings in Avery Hill
Commercial buildings in London often have strict access rules and limited loading, 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.
Rented homes near Falconwood station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Managing a site like Stationers' Crown Woods Academy? Then service openings in fire-resisting walls need checking after any refurbishment. As a London address, Avery Hill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to several days, depending on how many gaps there are. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Avery Hill. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Clear the area around the work

Quotes for fire rated sealant in Avery Hill
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number and length of the joints
- The type of sealant required
- When we can work, for business premises
- Mould in or behind the old joints
Leaving a failed joint usually makes the job bigger, not smaller. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- Any access issues, like height or stairs
- If someone has resealed it before
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
Asking for a quote is easy: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Avery Hill: your questions answered
Can parking be tricky for a visit in Avery Hill?
Parking in Avery Hill, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Is Avery Hill in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Avery Hill is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or send us an email.
Are you fully insured?
Yes. Full insurance covers our work.
Do you work in flats, HMOs and commercial buildings?
Yes. Occupied flats, HMOs, offices and schools are all fine, with access planned around residents or staff. Early starts or out-of-hours work can be arranged if that suits the building.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can ordinary silicone be used in a fire-stopping gap?
No. It looks sealed but won’t perform as fire stopping. Use a product tested for that gap and service.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Take photos of fire stopping before ceilings or boxing go back
- Check risers, ceiling voids and cupboards during building checks
- Do not paint over fire sealant until it has cured
- Store the list of sealed gaps with your building paperwork
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record so the item can be closed.
