Questions from Lower Heyford

Do you cover smaller places like Lower Heyford?

Yes, Lower Heyford is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

I let a flat near Heyford station. Can you help?

Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.

What does intumescent mean?

Intumescent means it swells when heated, helping close the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

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

No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service and we can apply it for you.

How much does fire rated sealant cost in Lower Heyford?

We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.

How long will you be here?

As a guide, most jobs take from a few hours to a few days, depending on the number of gaps and the access. Larger jobs naturally take longer, and we’ll say how long yours will take.

Is there any odour?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

Fire rated sealant in Lower Heyford, done properly

Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on. We are often asked to deal with unsealed gaps where pipes and cables go through a wall and sealant items on a fire risk assessment action list, on linear gaps, plasterboard & masonry and service penetrations.

For holiday lets, converted business premises or a community building near Lower Heyford, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Can I do it myself?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What affects the quote in Lower Heyford

There’s no set price list, because no two jobs are the same. What we look at:

  • Any working-time requirements on site
  • How much there is to do
  • How much old sealant there is and how hard it is to remove
  • The number of rooms or windows

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

What to tell us for a quote

What to tell us when you ask for a quote:

  • A few pictures by email, if you can
  • Access, such as stairs, a lift or height
  • What the problem is, such as mould, gaps, leaks or cracking
  • Any previous sealing or DIY work

We don’t publish a price list. Instead, we give you a clear price for your job. To get started, call 0345 464 0079 or email us.

Different surfaces, different methods

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.

Masonry and concrete

Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before applying the sealant.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Plan fire stopping into any work that goes through walls or floors
  • Take pictures of fire stopping before ceilings or boxing go back
  • Check risers, ceiling voids and cupboards during building checks
  • Store the list of sealed gaps with your building paperwork

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.

Do you need fire rated sealant in Lower Heyford?

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.

Any of these means the joints need attention:

  • Holes left by a change of layout
  • Standard silicone or caulk in a fire-stopping gap
  • Open gaps behind door architraves
  • Unsealed gaps where pipes and cables go through a wall

If you look after a church, hall or community building such as Church of St Mary, service openings in its walls need the right fire-rated sealant, as in any building.

What to look for in a quote

  • Is VAT in the price?
  • How hidden problems are handled
  • How long to leave it before use
  • Whether they seal over old material or remove it

Choosing a sealant specialist

Fire rated sealant around Lower Heyford

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.

If you let a flat or house near Heyford station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as Dr Radcliffe's Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Leave it or put it right?

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. Around Lower Heyford, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

How it works

You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job. Somewhere as small as Lower Heyford, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Clear items away from the joints we are working on
  • Mention any sign-in or site rules at work premises
