About our fire rated sealant in Shirburn

Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you’re dealing with unsealed gaps where pipes and cables go through a wall and gaps filled with a product that isn’t fire-rated, we can help, on linear gaps, door frames and pipe & cable gaps alike.

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

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

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

  • File the fire-stopping record where your assessor can find it
  • Take pictures of fire stopping before ceilings or boxing go back
  • Include fire stopping when you schedule refits
  • Keep general-purpose foam and caulk away from fire-stopping gaps

Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.

Workplaces and buildings in Shirburn

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 work to the specification you’re given, installing the product to its tested details. There are hotels and other places to stay in and around Shirburn. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

For site and facilities teams at buildings such as Icknield Community College, fire-stopping around service openings should be restored whenever new services go in. Community buildings like All Saints Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Why deal with it now?

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that doesn’t depend on other work. Where a wall is exposed, as many are in small places like Shirburn, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

When something else is needed

New sealant can’t fix everything, and we will tell you before we start. Sealant will not put right:

  • Large holes that need a different fire-stopping system
  • A wall that is not a fire-resisting element to begin with
  • Deciding what fire stopping a building needs

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

What we seal

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

Different surfaces, different methods

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first.

Plasterboard walls

We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.

Questions from Shirburn

Is Shirburn within the area you cover?

Yes. Shirburn is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you cover Shirburn for fire rated sealant?

Yes. We work across London and the South East, and Shirburn is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.

How much does fire rated sealant cost in Shirburn?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

Do you work in flats, HMOs and commercial buildings?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we’ll plan around it.

Do you seal gaps around fire door frames?

Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.

What does intumescent mean?

Intumescent means it swells when heated, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned before resealing.

Can I use normal mastic around a pipe through a fire wall?

No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.

What we do, step by step

Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Shirburn, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your files.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know if you’ve seen damp or leaks
  • Plan for the work area to be out of bounds to pets and children
