Lime & Cob Repairs in Cornwall

A1 Complete Builders carries out lime and cob repairs across Cornwall, helping owners maintain and restore traditional cottages and historic properties. Based in Higher Fraddon and serving the Truro area and wider Cornwall, our family-run team works on projects from small patch repairs to substantial wall restoration.

Our work includes repairing damaged cob walls, rebuilding sections of traditional walling, lime rendering and lime plaster finishes. We use materials and methods suited to the existing construction, with attention to the condition of the wall and the causes of deterioration.

Whether you are dealing with damaged render, deteriorating cob or a wider renovation, tell us what you have found. We can discuss the work required and the next steps for your property.

Our approach starts with the building itself: its age, construction, condition and existing finishes. We consider suitable materials for each repair, including traditional aggregates, clay and lime, rather than treating every property in the same way.

For examples of completed work, browse our cob construction projects. If your repairs form part of a larger heritage project, see our building conservation and restoration service.

When you enquire, include the property’s location, a brief description of the problem and details of any survey or previous repair work. We will discuss your requirements and the appropriate next steps.
