cheaper to prevent than to repair a collapsed centenary oak beam

The problem

Most farmhouse buyers discover pathologies after signing

Active woodworm in oak beams

Appear healthy to the naked eye but have internal galleries that compromise the structure.

Structural damp by capillarity

Degrades masonry from the inside. Invisible until it causes serious damage.

Subterranean termites

Advance from the foundations towards the wooden structure. Detected late, very costly.

Roof with hidden infiltrations

Require complete replacement. Not visible from the ground without drones.

Listed building without permits

Structural interventions require prior administrative authorisation. Delays and extra costs.

Unforeseen costs of €15,000–45,000

Average repair cost when pathologies are detected after purchase.
