Roughcast Repairs in Biggar , South Lanarkshire

In Lanark and the surrounding villages, you’ll hear people use both words. They both refer to the same thing: a mixture of lime, cement, and small stones (aggregates) applied to the outside of a building. Whether you call it roughcast, harling, or pebble dash, its main job is to act as a shield against the rain. We have forty years of experience working with these traditional materials, so we know exactly how to fix them properly.

It’s tempting to ignore a tiny crack, but in our experience, it is better to act fast. Water gets into those gaps, and when the temperature drops in winter, that water turns to ice and expands. This pushes the render away from the wall—what we call "blown" roughcast. If you hear a hollow sound when you tap your wall, the render has detached. We can cut these sections out and patch them up before the damage spreads.

Matching old roughcast is an art form. Because your original render has been exposed to the sun and rain for years, its colour will have changed. When we carry out a repair in Lanark, we take the time to find the right size and colour of stones to get as close a match as possible. We want the repair to be invisible, not a bright patch that stands out.

When we fix your masonry or render, we use high-quality materials designed to stand up to the local climate. A professional repair by a time-served tradesman can add years to the life of your walls. It is a cost-effective way to protect your home without the price tag of a full re-render.

We know how important your garden and driveway are. Our team makes a point of tidying up as we go. We protect your windows and paths before we start hacking off old render, and we make sure every bit of debris is cleared away once the job is done. You’ll be left with a solid, weatherproof wall and a clean site.

We do our best to match the texture and stone type. While a fresh repair might look slightly cleaner at first, it will weather down over time to blend in with the rest of the house.

Look for cracks, damp patches on internal walls, or areas where the render looks like it is bulging. If you are unsure, we can pop round to give your walls a quick check.

It depends on the temperature. If it is freezing, the mortar won't set correctly. We always check the forecast to make sure the conditions are right for a long-lasting fix.

Yes, if your external walls have been damaged by a storm or a falling tree, we can provide a detailed quote for your insurance company to help get the repairs sorted quickly.
