Pebble dash specialists for homes and businesses
Cracked, blown or tired pebble dash repaired properly. We cover Cardiff to Pembrokeshire, the Valleys to Cardigan Bay, with honest advice on whether to patch, re-dash, clean, paint or re-render.
Our services
Pebble dash is one of the most common wall finishes in Wales, and it does a hard job. It takes rain blown in off the Atlantic and the Bristol Channel, frost on Valleys hillsides and salt air along the coast. Most of the time it copes well, but once cracks open or the render loses its grip on the wall, water gets in and the damage speeds up.
We specialise in pebble dash. That means crack repairs, colour-matched patches, full re-dashing, careful removal, soft-wash cleaning, painting and modern render systems. Our team has decades of experience in home improvement and repair, and we work on private homes, rented houses and commercial premises across South and West Wales. Every job starts with a look at the wall and a straight answer about what it needs.

Know the signs
How it works
We visit, tap the render to find hollow areas, look at cracks and check gutters, sills and ground levels to understand what is causing the damage.
You get a clear written quote explaining what we recommend and why, with alternatives where they make sense, so you can decide without pressure.
We protect your property, cut back to sound render, rebuild the coats and apply the dash or finish in suitable weather, keeping the site tidy throughout.
We tidy the edges, clear away waste, walk round the work with you and explain any aftercare, such as leaving new render to cure before cleaning.

We are not general builders who occasionally render. Repairing, matching and replacing pebble dash is our focus, so we know how old dash behaves and what goes wrong with it.
Old dash cannot always be matched perfectly. We sample your stones, show you a test patch and tell you plainly how close we can get before any work starts.
A crack or blown patch usually has a reason, from a leaking gutter to a rusting lintel. We find it and deal with it, so the repair is not fighting the same problem.
Render needs dry weather above about 5°C to cure. We plan around the forecast and protect the work, and we will move a date rather than rush a job.

A painted 1930s semi with cracks running from the front window corners and a damp patch inside. We traced the cause, repaired the cracks and repainted the front elevation.

A terraced house facing Swansea Bay with hollow render across most of the front. Patching would not have lasted, so we stripped and re-dashed the elevation to match neighbours.
Typical job exampleRead the case studyA post-war semi with several blown areas around pipes and below sills. We patched them using a blend of aggregates sampled to match the existing natural dash.

We work across South and West Wales: Cardiff and the Vale, Newport and Gwent, the Valleys, Bridgend, Swansea Bay, Carmarthenshire, Pembrokeshire, and up to Cardigan Bay, Aberystwyth and Brecon. Our areas page lists the towns.
We get as close as possible by sampling your stones, blending aggregates and showing you a test patch. On old or weathered dash an exact match is not always achievable, and we will tell you honestly before we start.
If most of the render is sound, repairs are usually the best value. If large areas are hollow or cracked, re-dashing may be more sensible long term. We tap the whole wall and explain which option we would choose and why.
Yes. Call us on 07565 147 170 or use the contact form. We will arrange a visit, look at the wall and give you a written quote.
Render needs dry weather above about 5°C to cure, so we avoid frost and heavy rain. Surveys, quotes and some small repairs can happen year round, while larger jobs are planned for suitable weather.
Yes. We work for landlords, agents, housing associations, shops and business premises, as well as homeowners. See our commercial page for how we approach those jobs.
