How external mastic works in Edinburgh

Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. We work on concrete & block, façade panels and joints between brick and frames, and common reasons people get in touch are old sealant gone brittle and cracked and rain getting behind render or cladding at a joint.

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access.

Each joint is checked and the colour of the new sealant agreed.
We take out the old sealant until the faces are sound.
Backing rod goes in so the sealant can stretch between the two faces.
Primer is applied wherever the sealant needs it.
A low-modulus exterior sealant is gunned in and tooled to a neat finish.

What affects the price in Edinburgh

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Walls and rooflines across Edinburgh

Edinburgh has everything from period brickwork to rendered and clad modern buildings. The joints between different materials are the usual weak points.

Our work covers the whole of Scotland, Edinburgh included. Journeys are planned ahead, and outside jobs are booked around the forecast. Along the coast in Edinburgh, window and wall joints facing the sea take the brunt of the weather, and that’s where sealant usually gives up first. Good preparation and the right sealant help it cope.

Edinburgh: For an older house near a landmark such as St Cuthbert's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Haymarket station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY versus a professional finish

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. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Why deal with it now?

Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first.

Landlord and commercial work in Edinburgh

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order.

What we are called out for in Edinburgh

Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.

The problems people usually mention when they call include:

Moss and dirt in joints with no sealant left
Rain getting behind render or cladding at a joint
Failed sealant between panels on a façade
Cracked joints where brick meets render or frames

Looking after it afterwards

A little care helps the new joints last. We recommend:

Walk round the building once a year and look at the joints
Show decorators and builders where the movement joints are
Make sure movement joints are not pointed over
Clear growth from the base of walls and joints

Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants are not designed to be painted and spoil the finish.

If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.

Common questions in Edinburgh

Do you hold any approvals?

Yes. We’re approved under the ARBOMaster scheme.

Is there any odour?

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Do you seal joints where cladding meets other materials?

Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.

I rent my home. Can I book you?

Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.

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 does not work out, we can redo it.

Can you work on commercial sites?

Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.

What is a movement joint?

A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
