Fire rated sealant near Somers Town

Fire rated sealant for homes and businesses in Somers Town

Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. We work on flats & HMOs, door frames and linear gaps, and common reasons people get in touch are holes left by a change of layout and gaps around pipes and cables through fire-resisting walls.

Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Somers Town.

Whatever the size of the job, you get the same one-year guarantee.

The process

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of gaps, and longer for a whole building and we leave things clean and tidy. In Somers Town, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know if you’ve seen damp or leaks

Advice

Can I do it myself?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

When something else is needed

We will not take on work that won’t last, so here’s what sealant can’t put right:

  • Fire risk assessments, which need a qualified assessor
  • Walls or floors that weren’t built to resist fire
  • Fire doors that need new seals, closers or hardware

Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.

Surfaces we seal

Fire rated sealant around Somers Town

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Somers Town has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.

Rented homes near London Euston station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as St Mary's Church, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like St Mary and St Pancras Church of England Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Questions from Somers Town

Can parking be tricky for a visit in Somers Town?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Do you work for landlords with property near London Euston station?

Yes. We work for landlords and agents as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.

Where do you work from?

We work from Crawley. Our applicators cover Somers Town.

Will you assess my building’s fire safety?

No, we don’t assess buildings. When your assessor or designer has set out what’s needed, we will quote for the sealant work on it.

Will the old sealant be removed?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Do you come to Somers Town?

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

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit.

Do you offer different sealant colours?

In most cases you can choose. We’ll explain which colours are available.

Surface by surface

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Service penetrations

New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.

Landlords, agents and businesses in Somers Town

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

How to look after the new joints

Aftercare is simple, and it makes a real difference:

  • Include fire stopping when you schedule refits
  • Get damaged fire seals looked at promptly
  • Include hidden areas like risers in routine checks
  • Ask every contractor to reseal any fire stopping they disturb

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.

An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
