Practical sustainable solutions for everyday building problems


CPA uses non-invasive and non-destructive investigation techniques as appropriate for the proper identification of structurally significant defects and the diagnosis of the cause of instability problems. This step process governs the strategy and options for specifying necessary sympathetic repairs, strengthening or enhancements, and may be used in prescribing a future maintenance strategy.

CPA possess the detailed knowledge, understanding and appreciation of the often conflicting demands for taking appropriate care of old, and possibly very frail, material whilst adapting listed buildings for continued use or new occupation.
