Questions from Edmonton
Can you do fire rated sealant in Edmonton?
Yes. Our work covers London and the South East, and Edmonton is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
Is parking a problem for a job in Edmonton?
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.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you work in occupied buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.
Can you give us a record of the work?
Yes. You get a list of where we worked and what we used.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Edmonton, along with the rest of our area.
Do you certify the fire stopping?
We do not certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and giving you a record of where it went.
Fire rated sealant in Edmonton
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 work on door frames, service penetrations and linear gaps, and common reasons people get in touch are gaps where walls meet ceilings or slabs and gaps left after a refit or conversion.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Edmonton, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Why deal with it now?
A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. In a flat in Edmonton, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
What fire rated sealant looks like in Edmonton
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
Schools such as Brettenham Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as All Saints' Church, older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Edmonton Green station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Edmonton is about 9 miles north-east of City of Westminster, in Greater London.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. For a job in Edmonton, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- 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.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask every contractor to reseal any fire stopping they disturb
- Allow for resealing whenever new services are run
- Keep the record of products and locations with your fire safety documents
- Ask which product was used before you paint
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.

What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Sign-off of the building, which sits with building control or your assessor
- A wall that isn’t a fire-resisting element to begin with
- Big openings where sealant alone isn’t the tested solution
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.
