About our fire rated sealant in High Hurstwood

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. We are often asked to deal with sealant items on a fire risk assessment action list and ordinary sealant used where a fire-rated product was needed, on plasterboard & masonry, linear gaps and service penetrations.

If you have holiday lets, a converted barn used for business or a community building near High Hurstwood, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

Workplaces and buildings in High Hurstwood

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.

If you look after a church, hall or community building such as Holy Trinity Church, older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Buxted station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

What affects the cost of fire rated sealant

We quote each job individually. These are the things that affect it:

  • Whether the work is at height
  • The size of the job
  • The type of sealant required
  • The old material and how stubborn it is

We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email.

Asking for a quote

There’s no need for technical detail. Just tell us:

  • Whether it’s a home or a business
  • The rough size of the job
  • A few pictures by email, if you can
  • Access, such as stairs, a lift or height

Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Your questions about fire rated sealant in High Hurstwood

Can you do fire rated sealant in High Hurstwood?

Yes. Our work covers London and the South East, and High Hurstwood is part of that. Just phone 0345 464 0079 or email us with a few details of the job.

Do you cover smaller places like High Hurstwood?

Yes, High Hurstwood is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Is standard sealant good enough for a fire gap?

No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.

Do you carry out fire risk assessments?

No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.

Will we have a record of what was sealed?

Yes. Every gap we seal is listed with the product used, so you have it on file.

Do you seal gaps around fire door frames?

Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.

Can I do it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

What information do you need?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.

How the visit works

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. In a small place like High Hurstwood, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. Every location is recorded with the product used for your records.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any tricky access

Advice

How the job changes by surface

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we will tell you.

Flats and HMOs

Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product and record where they are.

Honest limits

In fairness, there are a few things sealant won’t fix:

  • Openings too large for sealant, which need batts, boards or another system
  • Construction that does not provide fire resistance on its own
  • Sign-off of the building, which sits with building control or your assessor

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

Surfaces we seal

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

Signs you need fire rated sealant in High Hurstwood

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried.

Look out for any of the following:

  • Unsealed gaps where pipes and cables go through a wall
  • Fire seals that have cracked with movement
  • Gaps where walls meet ceilings or slabs
  • Holes left by a change of layout

Managing a site like High Hurstwood Church of England Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

Questions to ask before booking

  • What product goes in the joint
  • Whether they seal over old material or remove it
  • What guarantee comes with the work
  • What the cure time is
