How long does the job take?
Typically it takes from a few hours to a few days, depending on the number of gaps and the access. Larger jobs naturally take longer.
Will we have a record of what was sealed?
Yes. We note each location and the product that went in.
What fire rating will the seal have?
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, recording the locations and products.
Can I use normal mastic around a pipe through a fire wall?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. If it’s been used, we remove it and use the right product.
About our fire rated sealant in Holloway
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. We are often asked to deal with seals cut through by electricians, plumbers or data installers and unsealed gaps where pipes and cables go through a wall, across pipe & cable gaps, service penetrations and door frames.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Holloway, we agree timings and access before anything starts.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Fire rated sealant in Holloway: local notes
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a building such as Grafton Primary School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like St Joseph and St Padarn's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Common problems we fix in Holloway
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.
The most common problems we see are:
- Open gaps behind door architraves
- Open holes round services passing through fire walls
- Holes left by a change of layout
- Gaps where walls meet ceilings or slabs
Letting a property close to Drayton Park station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Questions to ask before booking

Landlords, agents and businesses in Holloway
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
How the job changes by surface
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.
Door frames
Frame gaps are generally hidden behind the architrave. We seal any open gap to the product’s tested details.
Quotes for fire rated sealant in Holloway
The quote reflects the job in front of us. We look at:
- Working hours on commercial sites
- The number and length of the joints
- Access and height
- Whether there’s mould to deal with
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- What’s wrong with the joints now
We don’t publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To get started, call 0345 464 0079 or email us.
The process
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. 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.
- We start with the survey or action list, checking the size and surfaces of every gap.
- 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.
How to prepare
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Related advice
Why it’s worth doing now in Holloway
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Holloway.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Store the list of sealed gaps with your building paperwork
- Photograph sealed gaps before they’re covered up
- Report cracked or damaged seals as soon as you notice them
- Check whether a sealant can be painted before decorating over it
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.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
