Fire rated sealant near Inverarnan

Fire rated sealant in Inverarnan, done properly

Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. Typical jobs include fire seals that have cracked with movement and ordinary sealant used where a fire-rated product was needed, on pipe & cable gaps, plasterboard & masonry and service penetrations.

In a smaller place like Inverarnan, commercial jobs are more likely to be a hotel, guest house, school, surgery or community hall than an office block. All of them have washrooms, kitchens and fire-rated joints that need looking after.

All of our work is guaranteed for twelve months, in Inverarnan and everywhere else we cover.

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What we do, step by step

On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work usually takes a few hours for a handful of gaps, and longer for a whole building. Outside jobs in Inverarnan need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. We record the locations and products used for your records.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about any previous sealing or DIY attempts
  • Mention any tricky access

How the job changes by surface

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the seal has something sound to bond to.

Door frames

Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.

How to look after the new joints

A little care helps the new joints last. We recommend:

  • Photograph sealed gaps before they’re covered up
  • Never patch a fire seal with standard sealant
  • Allow for resealing whenever new services are run
  • Make resealing part of every contractor’s brief

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.

A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so you can show it was dealt with.

Why deal with it now?

For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we will tell you. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear quote before we start.

  • Anti-fungal silicone where joints get wet

When to call us in Inverarnan

Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave does not always get resealed.

People normally contact us when they notice one of these:

  • Seals cut through by electricians, plumbers or data installers
  • Old fire sealant that has split or come away
  • Joints picked up in a fire-stopping survey
  • New service routes left unsealed after building work

For buildings such as Ardlui Church, service openings in its walls need the right fire-rated sealant, as in any building.

Questions from Inverarnan

How do Scotland’s building regulations apply to fire-rated sealant in Inverarnan?

Building work in Scotland comes under the Building (Scotland) Regulations and their technical handbooks. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that’s how we fit it. We don’t certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.

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

Yes, we work for landlords and letting agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.

Do you provide details of the products used?

Yes. Every gap we seal is listed with the product used, so you have it on file.

Is intumescent sealant the same as fire-rated sealant?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.

How long does the job take?

Typically it takes anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer.

Are you an approved applicator?

Yes. We hold ARBOMaster approved applicator status.

Will there be a smell?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Will you assess my building’s fire safety?

No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
