Fire rated sealant in Over Norton

Fire rated sealant in Over Norton, done properly

Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That is the part we focus on. We are often asked to deal with new service routes left unsealed after building work and sealant items on a fire risk assessment action list, on service penetrations, flats & HMOs and door frames.

For a small place like Over Norton, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Workplaces and buildings in Over Norton

There are hotels and other places to stay in and around Over Norton. Hotel work can be planned room by room, with out-of-hours working where needed. 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.

If you look after a building such as Holy Trinity Catholic School, fire-stopping around service openings should be restored whenever new services go in.

Different surfaces, different methods

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the sealant bonds.

Can I do it myself?

A careful DIYer can reseal a simple joint, 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.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Signs you need fire rated sealant in Over Norton

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common particularly when it was the last job before handover.

It’s worth asking for a quote if you see:

  • Open holes round services passing through fire walls
  • Linear gaps at the head of walls
  • Open gaps behind door architraves
  • Ordinary sealant used where a fire-rated product was needed

Community buildings like St James are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Questions to ask before you book

  • Are they insured?
  • How long the guarantee is
  • Is VAT in the price?
  • Whether they seal over old material or remove it

How to choose a mastic man

Leave it or put it right?

For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. Where a wall is exposed, as many are in small places like Over Norton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Questions from Over Norton

Can you do fire rated sealant in Over Norton?

Yes, Over Norton is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing.

Do you cover smaller places like Over Norton?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is the work guaranteed?

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

How long does the job take?

As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer.

What does fire rated sealant cost?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.

Do you offer different sealant colours?

We help you choose a colour that suits. The product needed can limit the range.

Can you tell me how many minutes the seal will last?

Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and list the locations and products for you.

Can you work in occupied buildings?

Yes. We regularly work in flats, HMOs, schools and offices while they’re in use and we plan access around the people using them. Early starts or out-of-hours work can be arranged where it’s needed.

Looking after it afterwards

After the cure time, these simple habits help:

  • Allow for resealing whenever new services are run
  • Never patch a fire seal with standard sealant
  • Get damaged fire seals looked at promptly
  • Make resealing part of every contractor’s brief

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record.

How we quote for fire rated sealant

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

  • The product the joint needs
  • The old material and how stubborn it is
  • The number of rooms or windows
  • How easy the joints are to reach

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What we need to know

Before you ask for a quote, have a think about:

  • If it’s domestic, commercial or a hotel
  • The address or postcode of the job
  • How we’d reach the joints
  • Any previous sealing or DIY work

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or email us.
