Fire Rated Sealant in Dalston
Problem with your fire-stopping gaps in Dalston? We cut out the old, prepare the joints and apply the right sealant.
- Linear gaps at the head of walls
- Open holes round services passing through fire walls
- New service routes left unsealed after building work
Why deal with it now?
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Dalston.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

Fire rated sealant in Dalston, done properly
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment on buildings across Dalston. If you share the list, we can quote for the gaps that need fire-rated sealant. If you are dealing with damaged fire sealant left by other trades and unsealed gaps where pipes and cables go through a wall, we can help.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Dalston, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
You get a 12-month guarantee, the same in Dalston as everywhere else we work.

When to call us in Dalston
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
Signs it’s time to call us include:
- New service routes left unsealed after building work
- Open joints along the top of partitions
- Sealant items on a fire risk assessment action list
- Seals cut through by electricians, plumbers or data installers
If you look after a church, hall or community building such as Holy Trinity Church, gaps around pipes and cables are worth checking after any building work there.

Dalston questions
Do you work in hotels near Dalston?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can you help a landlord with a rental near Dalston Junction station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
What does intumescent mean?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you carry out fire risk assessments?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Surface by surface
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist, and we’ll say if we spot a problem with them.
Also in Dalston
When something else is needed
To be straight with you, some problems need a different trade:
- Openings too large for sealant, which need batts, boards or another system
- Sign-off of the building, which sits with building control or your assessor
- Construction that doesn’t provide fire resistance on its own
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
Joints and surfaces we work on
- Flats & HMOs
- Service penetrations
- Plasterboard & masonry
- Door frames
- Linear gaps
- Pipe & cable gaps
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Tell trades working in the building that fire seals must be put back
- Get damaged fire seals looked at promptly
- Do not paint over fire sealant until it has cured
- Keep pictures of seals that will be hidden
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.
How the visit works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In a London area like Dalston, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We start with the survey or action list, checking the size and surfaces of every gap.
- 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.
- 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.
Before we arrive
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

Advice
Fire rated sealant around Dalston
Dalston has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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.
Schools such as Holy Trinity Church of England Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. If you let a flat or house near Dalston Junction station, any gap left by new services in shared walls should be closed with a fire-rated product.
