How we handle fire rated sealant in Steventon

A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That is the part we focus on, gap by gap. If you have unsealed gaps where pipes and cables go through a wall and holes left by a change of layout, we can put it right.

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

Every job is covered by a 12-month guarantee.

Should I try it myself first?

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.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Why it’s worth doing now in Steventon

A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In a small place like Steventon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

How the visit works

A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Steventon, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  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. We record what was done and flag anything that needs a different system.

Before we arrive

  • Keep pets and children clear of the area while we work
  • Let us know if you’ve seen damp or leaks
  • Try not to wet indoor joints just before the visit

Advice

What fire rated sealant looks like in Steventon

There are hotels and other places to stay in and around Steventon. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For buildings such as Church of St Michael and All Angels, gaps around pipes and cables are worth checking after any building work there. For landlords with property near Didcot Parkway station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Different surfaces, different methods

Flats and HMOs

In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance so residents know what to expect.

Linear gaps

A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.

FAQs for Steventon

Do you work for hotels and guest houses in Steventon?

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.

Will you come out to Steventon?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you do fire sealant around door frames?

Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.

Can you quote for more than one area?

Yes. Several rooms, windows or areas can go on one quote.

Can you tell me which gaps need fire stopping?

No, assessment is not something we do. When your assessor or designer has set out what’s needed, we will quote for the sealant work on it.

Can I choose the sealant colour?

Usually, yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.

Is the work guaranteed?

Yes. All our work carries our 12-month guarantee.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.

What we are called out for in Steventon

In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.

Common reasons people contact us include:

  • Standard silicone or caulk in a fire-stopping gap
  • Damaged fire sealant left by other trades
  • Sealant items on a fire risk assessment action list
  • Gaps around pipes and cables through fire-resisting walls

Schools such as St Michael's Church of England Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Before booking anyone

  • Whether they seal over old material or remove it
  • What insurance they hold
  • Who turns up on the day
  • Which colour the sealant will be

Our hiring checklist

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • Walls or floors that weren’t built to resist fire
  • Big openings where sealant alone isn’t the tested solution
  • Doors that aren’t fire doors in the first place

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

Surfaces we seal

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

What affects the cost of fire rated sealant

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

  • How much old sealant there is and how hard it is to remove
  • Whether the work is at height
  • When we can work, for business premises
  • The number of rooms or windows

Combining jobs into one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

  • Any previous sealing or DIY work
  • Photos by email, if that’s easy
