Our dedicated team of qualified surveyors provides comprehensive inspection services for commercial and residential properties. We identify existing and potential issues from heat loss and timber rot to water ingress, enabling informed decision making about necessary remedial works.
A thorough property inspection is the foundation of effective building maintenance and improvement. Our surveyors meticulously examine structures for signs of deterioration, defects, and corrosion.
We assess waterproofing systems, dampness, timber integrity, heat loss, and gas barriers, providing detailed condition reports that highlight both visible and hidden problems that could affect your property’s performance, safety, and value.
