Walls and rooflines in Crieff

Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

In the older streets around St Michael's Hall, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Morrison's Academy, larger buildings have long runs of movement joint that eventually need resealing.

External mastic for homes and businesses in Crieff

We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. If you have cracked joints where brick meets render or frames and movement joints filled with mortar instead of sealant, we can put it right, on façade panels, brickwork movement joints and concrete & block alike.

Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard.

Big or small, you get the same one-year guarantee.

How the job changes by surface

Cladding and façade panels

Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.

Concrete and blockwork

Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.

Your questions about external mastic in Crieff

Will you come out to Crieff?

Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.

Is Crieff in your area for external mastic?

Yes, Crieff is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.

Is it OK to seal over old sealant?

No. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Can you match the colour of my brickwork?

The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.

Can you seal joints between render and window frames?

Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.

I rent my home. Can I book you?

Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.

Can you do several jobs on one visit?

Yes, we can. More than one area can go on one quote.

Is it worth trying it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

Aftercare tips

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

  • Check the sealant is paintable before painting near it
  • Wash walls gently around the sealant
  • Never let anyone fill a movement joint with mortar
  • Fix overflowing gutters above sealed joints

Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.

If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

A careful DIYer can reseal a simple joint, 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.

What affects the quote in Crieff

We quote each job individually. These are the things that affect it:

  • The amount of work
  • How many rooms, windows or areas are involved
  • The type of sealant required
  • Whether the work is at height

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Helping us quote

What to tell us when you ask for a quote:

  • Roughly how big the job is
  • The type of property
  • Photos by email, if that’s easy
  • How we’d reach the joints

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.

For landlords and businesses

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.

We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured.

Why it’s worth doing now in Crieff

Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Why book with us

  • A choice of colours where the product allows
  • 180+ five-star Google reviews
  • Experience in homes, commercial sites and hotels
  • Quality sealants from Arbo and Everbuild

The process

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes anything from a few hours to several days, depending on the building. Outside jobs in Crieff need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.

  1. We start by checking each joint, agreeing the ones to redo and how we will reach them.
  2. The old mastic and anything lodged in the joint is removed.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

How to prepare

  • Clear items away from the joints we are working on
  • On commercial sites, let us know about site rules
  • Plan for the work area to be out of bounds to pets and children
