Fire rated sealant in Nazeing

Fire rated sealant in Nazeing, done properly

We often work from an action list drawn up by a fire risk assessor. If you share the list, we can quote for the gaps that need fire-rated sealant. Common call-outs are for fire stopping disturbed by later work and old fire sealant that has split or come away, on pipe & cable gaps, door frames and service penetrations.

Somewhere as small as Nazeing, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

All of our work is guaranteed for twelve months.

Different surfaces, different methods

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall.

Flats and HMOs

Conversions normally leave a mix of old and new service holes. We seal the ones on your specification with a tested product and the locations noted.

Landlord and commercial work in Nazeing

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.

Why deal with it now?

Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we will tell you. Around Nazeing, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

What it costs depends on how much there is to do, 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.

What you get with us

  • Any old sealant cut out fully, not covered over
  • 20+ years of sealant experience
  • We leave the area clean and tidy
  • ARBOMaster approved applicator

What sealant work can’t fix

It helps to know what we can’t do too:

  • Doors that are not fire doors in the first place
  • Large holes that need a different fire-stopping system
  • Assessing a building’s fire safety

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

Joints and surfaces we work on

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

What happens on the day

There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes from a few hours to a few days, depending on the number of gaps and the access, including the tidy-up. For a village or hamlet like Nazeing, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • On commercial sites, let us know about site rules
  • Mention any parking rules near the property

Ask for a quote

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.

How to look after the new joints

Simple care keeps the joints in good condition. We recommend:

  • File the fire-stopping record where your assessor can find it
  • Allow for resealing whenever new services are run
  • Look in service cupboards and ceiling voids from time to time
  • Ask which product was used before you paint

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.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.

Fire rated sealant around Nazeing

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

Schools such as Water Lane Primary Academy are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like Church of All Saints are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Signs you need fire rated sealant in Nazeing

Much fire stopping is hidden: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

Most people get in touch when they notice one of these:

  • Gaps left after a refit or conversion
  • Joints picked up in a fire-stopping survey
  • Unsealed gaps where pipes and cables go through a wall
  • Standard silicone or caulk in a fire-stopping gap

Letting a property close to Roydon station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Questions to ask before booking

  • Who does the work, and how experienced they are
  • How the surfaces are prepared before sealing
  • What insurance they hold
  • Whether you can choose the colour
