About our fire rated sealant in Dalabrog

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. We work on door frames, linear gaps and plasterboard & masonry, and common reasons people get in touch are holes left by a change of layout and gaps flagged on a fire risk assessment.

For a place like Dalabrog, the journey and timings are planned in advance, so the job can fit around guests, residents or opening hours where possible.

Whatever the size of the job, you get the same one-year guarantee in Dalabrog and across Na h-Eileanan Siar.

What the job involves on each surface

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Flats and HMOs

Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance.

What we are called out for in Dalabrog

Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.

Keep an eye out for these signs:

  • Gaps left after a refit or conversion
  • Gaps flagged on a fire risk assessment
  • Open joints along the top of partitions
  • Seals cut through by electricians, plumbers or data installers

Around Dalabrog, as everywhere, fire rated sealant is only as good as the preparation behind it.

10 questions to ask before booking

DIY versus a professional finish

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.

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.

Quotes for fire rated sealant in Dalabrog

  • Access and height
  • Any mould that needs treating
  • How much old sealant there is and how hard it is to remove

Helping us quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • The problem you’ve noticed
  • A few pictures by email, if you can
  • How many joints, rooms or windows are involved
  • Whether it has been sealed before

We quote each job on its own, so the first step is telling us about yours. Just drop us a line at info@mrmastic.co.uk with the details.

Commercial buildings in Dalabrog

If you run a hotel, guest house or holiday let in a coastal place like Dalabrog, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we do not certify buildings or carry out fire risk assessments.

Community buildings like Daliburgh Parish Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Dalabrog (Gaelic: Daliburgh) is in Na h-Eileanan Siar. Jobs in Dalabrog get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Our Na h-Eileanan Siar coverage runs to 87 places, and Dalabrog is one of them.

Questions from Dalabrog

Is Dalabrog in your area for fire rated sealant?

Yes. We work across all of Scotland, and Dalabrog is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.

Do you cover smaller places like Dalabrog?

Yes, we do. We work across all of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.

Do the sealants smell?

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

What does intumescent mean?

An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.

Will the old sealant be removed?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Will you leave a mess?

We keep the work tidy. Nearby surfaces are protected.

Is standard sealant good enough for a fire gap?

No. Ordinary silicone, caulk or foam is not tested as fire stopping. If it’s been used, we remove it and use the right product.

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

We do not issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.

When something else is needed

New sealant can’t fix everything, and we’ll tell you before any work starts. It won’t solve:

  • Deciding what fire stopping a building needs
  • Issuing a fire rating or certificate for a building
  • Large holes that need a different fire-stopping system

Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.

Joints and surfaces we work on

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

What happens on the day

We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Outside jobs in Dalabrog need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Locations and products are noted so you have them on file.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints

Looking after it afterwards

How long the joints last depends on use and care. We suggest:

  • Photograph sealed gaps before they’re covered up
  • Include hidden areas like risers in routine checks
  • Ask every contractor to reseal any fire stopping they disturb
  • Check whether a sealant can be painted before decorating over it

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot and we will tell you which one you have.

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