Fire rated sealant near Stornoway

When something else is needed

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:

  • Issuing a fire rating or certificate for a building
  • Problems with the door itself rather than the gap around the frame
  • Big openings where sealant alone is not the tested solution

Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before you book.

Where we work in Stornoway

Fire rated sealant in Stornoway, done properly

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. We are often asked to deal with ordinary sealant used where a fire-rated product was needed and fire stopping disturbed by later work, across service penetrations, pipe & cable gaps and plasterboard & masonry.

Work in a place like Stornoway is planned ahead, journey included, so the job can fit around guests, residents or opening hours where possible.

You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

What affects the cost of fire rated sealant

Jobs vary more than people expect. What affects the quote:

  • When we can work, for business premises
  • Any mould that needs treating
  • How many rooms, windows or areas are involved
  • How much old sealant there is and how hard it is to remove

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Looking after it afterwards

Simple care keeps the joints in good condition. We recommend:

  • Plan fire stopping into any work that goes through walls or floors
  • Include hidden areas like risers in routine checks
  • Report cracked or damaged seals as soon as you notice them
  • Ask which product was used before you paint

Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so the item can be closed.

What the job involves on each surface

Door frames

Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist, and we will say if we spot a problem with them.

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.

What we do, step by step

We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job generally takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Stornoway may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Before we arrive

  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about stairs, lifts or work at height
  • Clear the area around the work

Related advice

DIY versus a professional finish

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Stornoway: your questions answered

Do you take on hotel work around Stornoway?

Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Are the rules for fire-rated sealant different in Scotland?

Scotland has its own building regulations, the Building (Scotland) Regulations, with their own 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 do not certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.

Can I do it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Are you ARBOMaster approved?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Can you tell me how many minutes the seal will last?

We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.

Is standard sealant good enough for a fire gap?

No. It might close the gap, but it is not a fire-rated seal. Use a product tested for that gap and service.

Can you give us a record of the work?

Yes. You get a list of where we worked and what we used for your files.

Do I have to be there?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

Signs you need fire rated sealant in Stornoway

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 round the new service isn’t always sealed again.

Most people get in touch when they notice something like this:

  • Linear gaps at the head of walls
  • Open gaps behind door architraves
  • Ordinary sealant used where a fire-rated product was needed
  • Joints picked up in a fire-stopping survey

For jobs in and around Stornoway, choosing the right material for each joint is as important as a tidy finish.
