Fire rated sealant for homes and businesses in Shoreditch

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. Typical jobs include gaps where walls meet ceilings or slabs and fire stopping disturbed by later work, on flats & HMOs, door frames and service penetrations.

London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Shoreditch needs to stay open, work can be planned outside normal hours.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Commercial buildings in Shoreditch

There are hotels and other places to stay in and around Shoreditch. Hotel work can be planned room by room, with out-of-hours working where needed. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.

Letting a property close to Shoreditch High Street station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as St Leonard's Church, service openings in its walls need the right fire-rated sealant, as in any building.

What happens on the day

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. In Shoreditch, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Locations and products are noted so you have them on file.

Preparing for the visit

  • Clear items away from the joints we are working on
  • For indoor joints, keep the area dry beforehand if you can
  • Plan for the work area to be out of bounds to pets and children

How the job changes by surface

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified, flat by flat if needed.

Plasterboard walls

We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.

What sealant work can’t fix

In fairness, there are a few things sealant will not fix:

  • Big openings where sealant alone is not the tested solution
  • Doors that are not fire doors in the first place
  • Certifying a building or signing off its fire safety

If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.

What we seal

  • Door frames
  • Plasterboard & masonry
  • Pipe & cable gaps
  • Linear gaps
  • Service penetrations
  • Flats & HMOs

What affects the cost of fire rated sealant

We quote each job individually. These are the things that affect it:

  • The size of the job
  • The number of rooms or windows
  • Any mould that needs treating
  • The old material and how stubborn it is

The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

Helping us quote

To make quoting easier, let us know:

  • If someone has resealed it before
  • What the problem is, such as mould, gaps, leaks or cracking
  • Pictures of the joints, sent by email
  • The rough size of the job

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or send us an email.

Why it’s worth doing now in Shoreditch

Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. 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. Dealing with it early is far simpler for homes in Shoreditch.

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Questions from Shoreditch

Do you work in hotels near Shoreditch?

Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

I let a flat near Shoreditch High Street station. Can you help?

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Do you cover Shoreditch?

Yes. From our base in Crawley, we cover South East England, London and all of Scotland.

Can you tell me which gaps need fire stopping?

No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we’ll quote for the sealant work on it.

Is intumescent sealant the same as fire-rated sealant?

An intumescent sealant expands when it gets hot to help seal the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.

Can you tell me how many minutes the seal will last?

Ratings and certificates are not something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.

Will it make a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

Where do you work from?

We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

Work for landlords, hotels and businesses

We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Common problems we fix in Shoreditch

Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.

If you can see any of these, it’s time to have the joints looked at:

  • Seals cut through by electricians, plumbers or data installers
  • Gaps flagged on a fire risk assessment
  • Open gaps behind door architraves
  • Gaps around pipes and cables through fire-resisting walls

Shoreditch is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
