About our fire rated sealant in Gallows Corner

We often work from an action list drawn up by a fire risk assessor on buildings across Gallows Corner. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. We work on service penetrations, linear gaps and door frames, and common reasons people get in touch are sealant items on a fire risk assessment action list and fire stopping disturbed by later work.

London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Gallows Corner, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

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

How we quote for fire rated sealant

Some jobs are bigger than they look, and some smaller. The main factors:

  • The type of sealant required
  • Any working-time requirements on site
  • The size of the job
  • The number of rooms or windows

The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

Asking for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • The problem you’ve noticed
  • Whether it has been sealed before
  • Where the property is
  • Any access issues, like height or stairs

Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll take it from there.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

The process

The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take from a few hours to a few days, depending on the number of gaps and the access, and we explain the cure time before we leave. In Gallows Corner, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We plan the order of work and access, floor by floor or flat by flat.
  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. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Before we arrive

  • Let us know about parking restrictions
  • Clear the area around the work
  • Let us know if you’ve seen damp or leaks

Leave it or put it right?

For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Gallows Corner, the repair is bigger than a sealant job.

A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

  • More than 20 years in sealant work

Fire rated sealant around Gallows Corner

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 work to the specification you are given, installing the product to its 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 Royal Liberty School? Then fire-stopping around service openings should be restored whenever new services go in. As a London address, Gallows Corner can be tricky for parking: let us know about parking bays, permits or a driveway.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Check whether a sealant can be painted before decorating over it
  • Photograph sealed gaps before they’re covered up
  • Flag any open gap you spot round a pipe or cable
  • Include hidden areas like risers in routine checks

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint and we’ll tell you which one you have.

Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

Common problems we fix in Gallows Corner

Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole round the new service isn’t always sealed again.

Keep an eye out for these signs:

  • Gaps flagged on a fire risk assessment
  • Unsealed gaps around fire door frames
  • Holes left by a change of layout
  • Cracked or shrunken fire-rated sealant

For landlords with property near Gidea Park station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Questions to ask before booking

  • What happens if the job turns out different

How to choose a mastic man

Gallows Corner: your questions answered

Can you help a landlord with a rental near Gidea Park station?

Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Do you cover Gallows Corner for fire rated sealant?

Yes, Gallows Corner is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.

Can you seal over the old sealant?

No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Will it make a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

How long will you be here?

Most jobs take anything from a few hours to several days, depending on how many gaps there are, including preparation and clearing up. Your quote will say how long we expect yours to take.

What’s the difference between intumescent and fire-rated sealant?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one option among several. We use whichever the specification and tested details call for.

Do you do fire sealant around door frames?

Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.

Do you certify the fire stopping?

We do not issue ratings or certificates ourselves. 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.

What sealant work can’t fix

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

  • Fire doors that need new seals, closers or hardware
  • A wall that isn’t a fire-resisting element to begin with
  • Certifying a building or signing off its fire safety

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