Lime and Cob Work

There’s a unique beauty and resilience in traditional building materials like lime and cob - but maintaining or repairing them takes specialist knowledge. At A1 Complete Builders, we’ve developed a deep understanding of these age-old methods, helping preserve Cornwall’s historic homes while ensuring they continue to breathe, flex, and function as intended.

Our lime and cob work ranges from small-scale patch repairs to full wall rebuilds, using compatible materials and techniques that respect the original construction. Whether we're hand-mixing cob from local clay or applying multiple coats of lime render, every step is carried out with precision and care. These natural materials aren’t just aesthetically pleasing - they play a vital role in managing moisture and maintaining structural health in older properties.

We’re proud to play a role in keeping Cornwall’s vernacular architecture alive. From site assessments and sample analysis to sourcing traditional aggregates and clay, we ensure every element is appropriate for the building’s age, location, and structure.

If you're repairing a cob wall, re-rendering with lime, or restoring a property built in the traditional Cornish style, A1 Complete Builders offers the expertise to do it right - ensuring your home remains both beautiful and breathable for years to come.
