External mastic near Earnock

How we handle external mastic in Earnock

Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. Typical jobs include old sealant gone brittle and cracked and moss and dirt in joints with no sealant left, on façade panels, joints between brick and frames and render & cladding joints.

In and around a place like Earnock, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

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

Common questions in Earnock

Can you help a landlord with a rental near Chatelherault station?

Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.

Is Earnock within the area you cover?

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

Is it messy?

No. The area is protected while we work and cleaned up afterwards.

What colours does the sealant come in?

The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.

Where is Mr Mastic based?

Our base is Crawley. Our area covers South East England, London and Scotland.

Do you seal joints where cladding meets other materials?

Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.

Are you an approved applicator?

Yes. We hold ARBOMaster approved applicator status and we are fully insured too.

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Leave it or put it right?

Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In a place like Earnock, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

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.

When something else is needed

We will not take on work that won’t last, so here’s what sealant cannot put right:

  • Render that’s blown, hollow or coming away
  • Cracked brickwork or render that needs a builder or plasterer
  • Cutting new joints into brickwork, which is building work rather than sealant work

If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

Walls and rooflines in Earnock

The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. 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.

For landlords with property near Chatelherault station, outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Hamilton Academy, its movement joints, gutters and trims need looking after like any other building’s.

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 call for the right materials, safe access and experience.

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.

When to call us in Earnock

The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.

Look out for these signs:

  • Hard, crazed mastic that has stopped moving
  • Leaking joints around cladding and façade panels
  • Rigid filler in a joint that should flex
  • Joints with sealant missing in places

Homes close to Hamilton South Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Questions to ask before booking

  • How long the guarantee is
  • Who turns up on the day
  • When the joint can take water or movement
  • Are they insured?
