Fire rated sealant in Brize Norton

Fire rated sealant in Brize Norton, done properly

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. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. If you are dealing with door frames with gaps between frame and wall and standard silicone or caulk in a fire-stopping gap, we can put it right, whatever the surface.

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

A one-year guarantee comes as standard.

What affects the cost of fire rated sealant

The price is agreed before any work begins. It takes into account:

  • When we can work, for business premises
  • The number and length of the joints
  • Whether there’s mould to deal with
  • The number of rooms or windows

The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before any work starts.

What to tell us for a quote

When you contact us, it’s useful to know:

  • Pictures of the joints, sent by email
  • Any access issues, like height or stairs
  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking

We do not publish a price list. Instead, we give you a clear price for your job. To get started, call 0345 464 0079 or drop us an email.

How the job changes by surface

Door frames

A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.

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’ll flag it.

What fire rated sealant looks like in Brize Norton

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.

Schools such as Brize Norton Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Brize Norton is about 1 mile east of Carterton, in Oxfordshire. Jobs in Brize Norton get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Brize Norton is one of 443 places in Oxfordshire where we work for fire rated sealant. Our Oxford page covers work nearby (14 miles or so).

Common problems we fix in Brize Norton

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, especially where it was squeezed in at the end of a project.

The problems people normally mention when they call are:

  • Fire stopping disturbed by later work
  • Linear gaps at the head of walls
  • Fire seals that have cracked with movement
  • Open gaps behind door architraves

If you look after a church, hall or community building such as Church of St Britius, older buildings that have had new heating or wiring often have service gaps worth checking.

What happens if it’s left?

Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. Around Brize Norton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Brize Norton: your questions answered

Is there a guarantee on fire rated sealant in Brize Norton?

All our work, in Brize Norton and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Will you come out to Brize Norton?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can ordinary silicone be used in a fire-stopping gap?

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

Can you work in occupied buildings?

Yes. Occupied flats, HMOs, offices and schools are all fine and we plan access around the people using them. Out-of-hours work can be arranged.

Do you provide details of the products used?

Yes. When the job is done, we give you the locations and products. If you need pictures or a set layout, ask when you get a quote.

Will there be a smell?

It depends on the product. Some smell for a while, some hardly at all.

How much does fire rated sealant cost in Brize Norton?

It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or email us with a short description of the job.

Do I need to be at home?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

What we do, step by step

There’s no need to move everything out before we come, just the space around the work. 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. Somewhere as small as Brize Norton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

How to prepare

  • Mention any tricky access
  • Let us know if you’ve seen damp or leaks
  • Clear the area around the work

For landlords and businesses

Letting agents and landlords in Brize Norton can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

When it is not the sealant

Before you book, it’s worth knowing the limits too:

  • Fire doors that need new seals, closers or hardware
  • Sign-off of the building, which sits with building control or your assessor
  • Walls or floors that weren’t built to resist fire

If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.
