Fire-rated sealant in Seven Dials, Brighton and Hove

What we are called out for in Seven Dials
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
The most common problems we see are:
- Fire seals that have cracked with movement
- Open gaps behind door architraves
- New service routes left unsealed after building work
- Open joints along the top of partitions
Rented homes near Brighton station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Seven Dials: your questions answered
Will you come out to Seven Dials?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Brighton station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
Can you work in occupied buildings?
Yes. Occupied flats, HMOs, offices and schools are all fine and we plan access around the people using them. Out-of-hours work can be arranged.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
How do I get a quote for fire rated sealant in Seven Dials?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you seal gaps around fire door frames?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame and we’ll tell you if we spot problems with the door.
Will we have a record of what was sealed?
Yes. When the job is done, we give you the locations and products. If you need photos or a set layout, ask when you get a quote.

What happens if it’s left?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. In an older home around Seven Dials, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us and we will talk you through it.

When it is not the sealant
A few problems are outside what sealant work can do:
- Deciding what fire stopping a building needs
- Problems with the door itself rather than the gap around the frame
- Sign-off of the building, which sits with building control or your assessor

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. For a job in Seven Dials, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- Mention if the joints have been sealed before

What the job involves on each surface
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for each gap size.
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 tell you if sealant alone isn’t the right fix.
Landlord and commercial work in Seven Dials
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Fire rated sealant in Seven Dials: local notes
If you run a hotel, guest house or holiday let in a coastal place like Seven Dials, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
If you look after a church, hall or community building such as St Luke's Church Prestonville, older buildings that have had new heating or wiring often have service gaps worth checking.
