External mastic for Westerton homes and businesses

The process

There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building for a typical job. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Westerton, it helps to know the floor, the door entry arrangements and the nearest parking.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. Failed sealant is removed back to clean, sound faces.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. We prime the faces where required.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Advice

How we handle external mastic in Westerton

Movement joints let brickwork, render and cladding expand and shrink without cracking. 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 concrete & block, render & cladding joints and copings & trims, and the jobs we see most are moss and dirt in joints with no sealant left and sealant that has lost its bond to the brick or render.

Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. In Westerton, those joints dry out over time and let water in behind the render or cladding.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

Copings and trims

Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible in all weathers.

Concrete and blockwork

Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap.

Westerton questions

Do you cover Westerton for external mastic?

Yes. Our work covers the whole of Scotland, and Westerton is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.

How do repairs to the shared parts of a tenement in Westerton get organised?

Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.

Can you work on commercial sites?

Yes. We have worked for hotels, offices and other businesses and we are fully insured.

Can you quote for more than one area?

Yes. Several rooms, windows or areas can go on one quote.

Can you seal joints between render and window frames?

Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.

What sealant do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.

What do you need from me for a quote?

A short description and the location, with photos by email if possible. If we need more, we will ask.

How do you reach high-level joints?

Each building is different. Send us pictures and a rough idea of the height, and we’ll confirm what access is needed.

Do you need external mastic in Westerton?

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 cannot move, so the wall cracks somewhere else instead.

Any of these means the joints need attention:

  • Rain getting behind render or cladding at a joint
  • Weeds or debris growing in open joints
  • Cracked joints where brick meets render or frames
  • Old sealant gone brittle and cracked

In the older streets around New Kilpatrick UP Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

10 questions to ask before booking

Why act early in Westerton

Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a tenement flat in Westerton, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.

Doing several joints on one visit is usually more efficient than separate visits. We will send you a clear quote for the lot.

Outside joints around Westerton

Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. The title deeds set out which parts are common. Westerton is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.

Rented homes near Westerton station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Knightswood Secondary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
