Our external mastic service in North Lanarkshire

A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. We work on façade panels, render & cladding joints and concrete & block, and people most often call us about joints pointed up with cement by mistake and rain getting behind render or cladding at a joint.

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation.

We start by walking round the building and agreeing the joints and the access.
Every bit of old sealant and any mortar or debris is cut out.
The faces are brushed clean and primed where the product requires it.
Backing rod sized to the joint goes in to set the depth.
The exterior sealant is applied, tooled and checked along its length.

Pricing in North Lanarkshire

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

External mastic across North Lanarkshire: local notes

In North Lanarkshire, external mastic work takes in houses, flats and commercial buildings, from Motherwell, Cumbernauld and Coatbridge to the quieter places in between. Outside joints can only be sealed when they’re dry, so the work is planned around the weather.

Our work covers the whole of Scotland, North Lanarkshire included. Longer journeys are planned in advance, and outdoor work around the weather.

Motherwell: Schools such as Braidhurst High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Motherwell station, outside joints that have cracked can let damp into a rental, so check them between lets.

Why it fails

Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.

Look out for any of the following:

Rain getting behind render or cladding at a joint
Joints pointed up with cement by mistake
Failed sealant between panels on a façade
Sealant that has lost its bond to the brick or render

What sealant work cannot fix

We will always be straight with you, so here’s what new sealant won’t do:

Walls that need new movement joints cut into them
Loose or hollow render, which needs re-rendering
Structural movement, which needs a surveyor or engineer

Should I try it myself first?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Why deal with it now?

Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs.

Different surfaces, different methods

Joints between dissimilar materials

Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.

Copings and trims

Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.

Common questions in North Lanarkshire

Do you take out the old sealant first?

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

How much does external mastic cost in North Lanarkshire?

Size, access and the old material all affect the cost. Ask us for a quote.

When will the joints need doing again?

It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away and have them redone then.

Do I have to be there?

We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.

Can you seal joints between two different materials?

Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces.

Can a movement joint be filled with mortar?

No. A mortar-filled joint can’t move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.

What is a movement joint?

It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
