Why it’s worth doing now in Murthly

Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

External mastic for homes and businesses in Murthly

Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the joint does not stand out. Typical jobs include rigid filler in a joint that should flex and gaps where render, brick and frames meet, across façade panels, joints between brick and frames and copings & trims.

External sealant needs dry surfaces, so outdoor work around Murthly is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.

Each job carries a 12-month guarantee.

Questions from Murthly

Will you come out to Murthly?

Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you work for landlords with property near Dunkeld & Birnam station?

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

What colours does the sealant come in?

The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.

What is backing rod for?

Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.

Will the old sealant be removed?

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

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

How long will you be here?

It depends on the size of the job, but most jobs take a few hours to a few days, depending on the length of joint and the access. We will tell you when we quote.

How long does external mastic last?

That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.

How it works

We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. Around Murthly, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.

  1. We look at every joint and agree a colour to suit the wall.
  2. Failed sealant is removed back to clean, sound faces.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Move anything stored near the joints
  • Tell us about any previous sealing or DIY attempts

Advice

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. A few tips:

  • Keep movement joints as flexible joints, not mortar
  • Show decorators and builders where the movement joints are
  • Clear growth from the base of walls and joints
  • Wash walls gently around the sealant

Do not paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted and spoil the finish.

Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

What affects the cost of external mastic

Your quote is based on your job. We take into account:

  • How easy the joints are to reach
  • How much old sealant there is and how hard it is to remove
  • When we can work, for business premises
  • Any mould that needs treating

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Asking for a quote

There’s no need for technical detail. Just tell us:

  • Roughly how big the job is
  • Any access issues, like height or stairs
  • Where the job is, and your postcode
  • Whether it has been sealed before

Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.

Honest limits

To be straight with you, some problems need a different trade:

  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Loose or hollow render, which needs re-rendering
  • Structural movement, which needs a surveyor or engineer

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

How the job changes by surface

Cladding and façade panels

Where a cladding system has its own specified sealant, we follow it or an approved alternative. Send us any details you have about the façade.

Render joints

Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.

Should I try it myself first?

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Walls and rooflines in Murthly

Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.

Letting a property close to Dunkeld & Birnam station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to United Presbyterian Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
