Trusted fire rated sealant in Broxbourne

Fire rated sealant in Broxbourne

We often work from an action list drawn up by a fire risk assessor for buildings in Broxbourne. Send us the list or the survey and we will quote for the fire-rated sealant work on it. Common call-outs are for seals cut through by electricians, plumbers or data installers and sealant items on a fire risk assessment action list, on door frames, linear gaps and plasterboard & masonry.

Community buildings, schools and small businesses around places like Broxbourne have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.

A one-year guarantee comes with the work, just as it does everywhere we cover.

When something else is needed

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

  • Construction that does not provide fire resistance on its own
  • Large holes that need a different fire-stopping system
  • Sign-off of the building, which sits with building control or your assessor

If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Where we work in Broxbourne

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

Surface by surface

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment, flat by flat if needed.

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.

Keeping the joints in good condition

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

  • File the fire-stopping record where your assessor can find it
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Flag any open gap you spot round a pipe or cable
  • Make resealing part of every contractor’s brief

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

How we quote for fire rated sealant

We quote each job individually. This is what makes a difference:

  • How many rooms, windows or areas are involved
  • How easy the joints are to reach
  • The product the joint needs
  • When we can work, for business premises

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

What we need to know

When you contact us, these details help:

  • The type of property
  • A few pictures by email, if you can
  • How we’d reach the joints
  • Any previous sealing or DIY work

For fire rated sealant in Broxbourne, ring 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and you will get a clear quote before we start.

What happens if it’s left?

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. In a smaller place like Broxbourne, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Common problems we fix in Broxbourne

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

The problems people usually mention when they call include:

  • Open joints along the top of partitions
  • Ordinary sealant used where a fire-rated product was needed
  • Open gaps behind door architraves
  • Gaps flagged on a fire risk assessment

For buildings such as Church of St Augustine, service openings in its walls need the right fire-rated sealant, as in any building.

What we do, step by step

The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job usually takes anything from a few hours to several days, depending on how many gaps there are, and we explain the cure time before we leave. Parking around Broxbourne is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  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. Any non-fire-rated filler is removed and the faces 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.

Getting ready for the visit

  • Mention any parking rules near the property
  • Mention if the joints have been sealed before
  • On commercial sites, let us know about site rules
