Fire rated sealant in Deddington

Fire rated sealant in Deddington

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. We work on pipe & cable gaps, door frames and service penetrations, and common reasons people get in touch are damaged fire sealant left by other trades and gaps flagged on a fire risk assessment.

For holiday lets, converted business premises or a community building near Deddington, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Every job comes with our 12-month guarantee.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. We suggest:

  • Ask every contractor to reseal any fire stopping they disturb
  • Keep the record of products and locations with your fire safety documents
  • Check risers, ceiling voids and cupboards during building checks
  • Photograph sealed gaps before they’re covered up

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.

Fire rated sealant around Deddington

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. There are hotels and other places to stay in and around Deddington. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

Letting a property close to Kings Sutton station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Church of St Peter and St Paul, service openings in its walls need the right fire-rated sealant, as in any building.

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.

Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

What affects the cost of fire rated sealant

We don’t publish a price list, because jobs vary so much. What we look at:

  • Any working-time requirements on site
  • How much there is to do
  • The type of sealant required
  • The number of rooms or windows

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

What we need to know

To help us quote quickly, please include:

  • If it’s domestic, commercial or a hotel
  • Where the property is
  • What’s wrong with the joints now
  • Any access issues, like height or stairs

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved and give you a clear quote.

FAQs for Deddington

Can you help a landlord with a rental near Kings Sutton station?

Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.

Do you work for hotels and guest houses in Deddington?

Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Can you do several jobs on one visit?

Yes. Just list everything you need and we will quote it together.

Will there be a smell?

That depends on the sealant. Some smell for a while, some hardly at all.

Will you leave a mess?

We keep the work tidy. We protect what’s around the joints.

Is standard sealant good enough for a fire gap?

No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.

Do you seal gaps around fire door frames?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself.

How do I get a quote for fire rated sealant in Deddington?

We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

When to call us in Deddington

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Common reasons people contact us include:

  • Ordinary sealant used where a fire-rated product was needed
  • Linear gaps at the head of walls
  • Gaps flagged on a fire risk assessment
  • Cracked or shrunken fire-rated sealant

For site and facilities teams at buildings such as Deddington Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

What your quote should include

  • What insurance they hold
  • Whether they seal over old material or remove it
  • What the cure time is
  • How the colour is chosen

10 questions to ask before booking

When something else is needed

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Sign-off of the building, which sits with building control or your assessor
  • Fire doors that need new seals, closers or hardware
  • Assessing a building’s fire safety

If in doubt, phone 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
  • Service penetrations
  • Plasterboard & masonry
  • Flats & HMOs
  • Linear gaps
  • Door frames

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

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.

What happens on the day

There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on how many gaps there are for a typical job. In a small place like Deddington, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • For indoor joints, keep the area dry beforehand if you can
  • For business premises, tell us about site rules or sign-in
