About our fire rated sealant in Wyatt's Green

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. We work on plasterboard & masonry, pipe & cable gaps and flats & HMOs, and people most often call us about sealant items on a fire risk assessment action list and old fire sealant that has split or come away.

In a village or hamlet like Wyatt's Green, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What we are called out for in Wyatt's Green

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.

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

  • Gaps filled with a product that isn’t fire-rated
  • Gaps around pipes and cables through fire-resisting walls
  • Door frames with gaps between frame and wall
  • Joints picked up in a fire-stopping survey

For site and facilities teams at buildings such as Doddinghurst Infant School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Questions to ask before booking

  • Whether VAT is included
  • The length of the guarantee
  • What product goes in the joint
  • How the surfaces are prepared before sealing

Can tenants book the work?

Of course. Check with your landlord; we can send the quote to them too.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

Will the old sealant be removed?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Do you hold any approvals?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Can I do it myself?

A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

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.

Commercial buildings in Wyatt's Green

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

For landlords with property near Shenfield station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Church of All Saints are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

What sealant work can’t fix

New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Fire doors that need new seals, closers or hardware
  • Issuing a fire rating or certificate for a building
  • Assessing a building’s fire safety

If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before you book.

Joints and surfaces we work on

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

The process

There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on how many gaps there are in most cases. For a village or hamlet like Wyatt's Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Plan for the work area to be out of bounds to pets and children
  • Tell us about access, such as stairs, a lift or high-level joints

What the job involves on each surface

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run leaving no stretch unsealed.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment.

How to look after the new joints

How long the joints last depends on use and care. Here’s what we suggest:

  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Ask which product was used before you paint
  • Include hidden areas like risers in routine checks
  • Plan fire stopping into any work that goes through walls or floors

Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
