Fire rated sealant in Pinner
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. If you have new service routes left unsealed after building work and linear gaps at the head of walls, we can put it right.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Pinner needs to stay open, work can be planned outside normal hours.
Big or small, you get the same 12-month guarantee in Pinner and across Greater London.

Fire rated sealant around Pinner
Many London buildings have tight access and loading restrictions, 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as Christian Science Church, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as West Lodge Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

- Unsealed gaps around fire door frames

How the visit works
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 a few hours for a handful of gaps, and longer for a whole building. In Pinner, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

Advice
Different surfaces, different methods
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the sealant bonds.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
Aftercare tips
A little care helps the new joints last. Our advice:
- Keep the record of products and locations with your fire safety documents
- Photograph sealed gaps before they’re covered up
- Tell trades working in the building that fire seals must be put back
- Check risers, ceiling voids and cupboards during building checks
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.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Leave it or put it right?
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing once someone inspects it. 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. Putting it right early is much less trouble.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will go through it with you.

Pinner questions
Is parking an issue for fire rated sealant in Pinner?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
I let a flat near Hatch End station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
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.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
How do I get a quote for fire rated sealant in Pinner?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email and let us know what needs doing and where.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
