Keeping the joints in good condition

A little care helps the new joints last. Our advice:

  • Include hidden areas like risers in routine checks
  • Check whether a sealant can be painted before decorating over it
  • Flag any open gap you spot round a pipe or cable
  • Store the list of sealed gaps with your building paperwork

Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

Fire rated sealant in Blackhill

Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through. We are often asked to deal with gaps where walls meet ceilings or slabs and open gaps behind door architraves, across service penetrations, flats & HMOs and linear gaps.

For a place like Blackhill, the journey and timings are planned in advance, so it can be fitted around bookings or opening times where possible.

Each job carries a 12-month guarantee, large or small.

What fire rated sealant looks like in Blackhill

For seaside hotels, guest houses and holiday lets around Blackhill, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. We install fire-rated sealant to the product’s tested details, though we don’t certify buildings or do fire risk assessments.

Whether the job is in Blackhill itself or nearby, the right material for each joint matters as much as a neat finish.

How the job changes by surface

Flats and HMOs

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 Blackhill

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

Building work in Scotland comes under the Building (Scotland) Regulations and their technical handbooks. Fire-rated sealant has to go in to the product’s tested details, and we follow them. We don’t certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.

Do you take on hotel work around Blackhill?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Do the sealants smell?

Some sealants have a smell while they cure. Opening a window helps.

Can I do it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

Can I add another job to the visit?

Yes. Just list everything you need.

Is there a guarantee?

Yes. There’s a 12-month guarantee on every job.

Can new sealant go over the old?

No, because it fails. We remove every bit of old sealant first.

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, or ask us to do it.

What we’re called out for in Blackhill

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 may look fine, but it is not a fire-rated seal.

Look out for these signs:

  • Linear gaps at the head of walls
  • Unsealed gaps around fire door frames
  • Standard silicone or caulk in a fire-stopping gap
  • Joints picked up in a fire-stopping survey

In and around Blackhill, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Choosing a sealant specialist

When something else is needed

Before booking, it’s worth knowing the limits too:

  • A wall that is not a fire-resisting element to begin with
  • Fire risk assessments, which need a qualified assessor
  • Large holes that need a different fire-stopping system

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

Joints and surfaces we work on

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

Leave it or put it right?

Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What happens on the day

You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap 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.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Let us know if you’ve seen damp or leaks
  • Try not to wet indoor joints just before the visit
