Fire rated sealant near Afton

Leave it or put it right?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Afton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

How we handle fire rated sealant in Afton

Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it. Typical jobs include sealant items on a fire risk assessment action list and standard silicone or caulk in a fire-stopping gap, across flats & HMOs, plasterboard & masonry and door frames.

Work in a small place like Afton is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

Big or small, you get the same one-year guarantee in Afton and across the Isle of Wight.

How we quote for fire rated sealant

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

  • Which sealant suits the joint
  • Whether the work is at height
  • Whether old sealant or filler has to be cut out
  • The number of rooms or windows

A failed joint rarely gets cheaper to fix by waiting. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Asking for a quote

When you call or email, these details help:

  • Where the job is, and your postcode
  • Whether it has been sealed before
  • How we’d reach the joints
  • What’s wrong with the joints now

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, ring 0345 464 0079 or email us.

How the job changes by surface

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each.

Door frames

Frame gaps are generally hidden behind the architrave. We seal any open gap to the product’s tested details.

Fire rated sealant around Afton

If you run a hotel, guest house or holiday let in a coastal place like Afton, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 are given, installing the product to its tested details.

Schools such as All Saints Church of England Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Community buildings like St. Agnes' Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

The process

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building in most cases. In a small place like Afton, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Finally, we list where we worked and what we used, for your records.

Preparing for the visit

  • Mention any tricky access
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us if parking is tricky

What we cannot put right

Sealant isn’t the answer to every problem, and we will tell you before work begins. Sealant will not put right:

  • Sign-off of the building, which sits with building control or your assessor
  • Doors that aren’t fire doors in the first place
  • Large holes that need a different fire-stopping system

If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Surfaces we seal

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

Landlord and commercial work in Afton

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Letting agents often deal with us directly. Tell us the address, the job and how access works.

How to look after the new joints

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Take pictures of fire stopping before ceilings or boxing go back
  • Never patch a fire seal with standard sealant
  • File the fire-stopping record where your assessor can find it
  • Don’t paint over fire sealant until it has cured

Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the list grows.
