About our fire rated sealant in Heyshott Green

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. Typical jobs include ordinary sealant used where a fire-rated product was needed and gaps flagged on a fire risk assessment, across flats & HMOs, linear gaps and pipe & cable gaps.

For a small place like Heyshott Green, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

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.

Different surfaces, different methods

Door frames

Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail and we will flag it.

Quotes for fire rated sealant in Heyshott Green

The quote reflects the job in front of us. We take into account:

  • The product the joint needs
  • Any working-time requirements on site
  • The number of rooms or windows
  • How easy the joints are to reach

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What to tell us for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • The rough size of the job
  • Any previous sealing or DIY work
  • Any access issues, like height or stairs
  • The type of property

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

How the visit works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Heyshott Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out 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

  • Tell us about any previous sealing or DIY attempts
  • For business premises, tell us about site rules or sign-in
  • Clear the area around the work

Why it’s worth doing now in Heyshott Green

Squirting in whichever sealant is nearest doesn’t 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. Where a wall is exposed, as many are in small places like Heyshott Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Why book with us

  • Fully insured
  • A 12-month guarantee on all work
  • Experience in homes, commercial sites and hotels
  • Approved under the ARBOMaster scheme

Workplaces and buildings in Heyshott Green

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 work to the specification you’re given, installing the product to its tested details.

Schools such as Midhurst Rother College are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Signs you need fire rated sealant in Heyshott Green

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.

These are the problems we are asked about most:

  • Open gaps behind door architraves
  • Unsealed gaps where pipes and cables go through a wall
  • Damaged fire sealant left by other trades
  • New service routes left unsealed after building work

Community buildings like The Parish Church of St James are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Questions to ask before booking

  • How long the guarantee is
  • Which colour the sealant will be
  • Whether VAT is included
  • What happens if the job turns out different
