Fire rated sealant for Lea Bridge homes and businesses

How we handle fire rated sealant in Lea Bridge

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you have unsealed gaps around fire door frames and old fire sealant that has split or come away, we can help.

In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Lea Bridge, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.

We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Ask which product was used before you paint
  • Flag any open gap you spot round a pipe or cable
  • Never patch a fire seal with standard sealant
  • File the fire-stopping record where your assessor can find it

Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.

What sealant work can’t fix

Some problems need a builder, plumber or other trade rather than us:

  • Deciding what fire stopping a building needs
  • Fire doors that need new seals, closers or hardware
  • Construction that does not provide fire resistance on its own

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

Surfaces we seal

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

Lea Bridge questions

Is parking a problem for a job in Lea Bridge?

Parking in Lea Bridge, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Do you work for landlords with property near Clapton station?

Yes. We work for landlords and letting agents as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.

Do you provide details of the products used?

Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.

Is it OK to seal over old sealant?

No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Do you take on fire stopping in schools and offices?

Yes. We regularly work in flats, HMOs, schools and offices while they’re in use and we plan access around the people using them. Out-of-hours work can be arranged if that suits the building.

How long does fire rated sealant take?

A typical job takes a few hours for a handful of gaps, and longer for a whole building, including preparation and clearing up. We will confirm how long when we quote.

Can you fill the gap behind a fire door frame?

Yes, if the gap is within the product’s tested range. Our work is the gap around the frame.

Do you guarantee your work?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.

How the visit works

You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of gaps, and longer for a whole building in most cases. For a job in Lea Bridge, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products.

Preparing for the visit

  • Tell us if parking is tricky
  • Tell us about any previous sealing or DIY attempts
  • Clear the area around the work

Why act early in Lea Bridge

Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. 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 Lea Bridge.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Why Lea Bridge customers choose us

  • Any old sealant cut out fully, not covered over
  • Sanitary silicone with an anti-fungal additive in wet areas
  • A 12-month guarantee on all work
  • We leave the area clean and tidy

Different surfaces, different methods

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first.

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.

Fire rated sealant around Lea Bridge

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.

Managing a site like Southwold Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like St Matthew are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. As a London address, Lea Bridge can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
