What it is
What Is Building Pathology?
Building pathology is the systematic study and diagnosis of building defects. It looks at how a building was constructed, how it is used, and how its materials, environment and history interact, in order to identify the underlying cause of a problem rather than just its visible symptoms.
Most failed repairs fail for the same reason: someone treated what they could see. Paint over the damp stain and it returns by winter. Fill the crack and it reopens along the same line. A chartered surveyor acting as a building pathologist works the other way round, cause first, then repair. It is the difference between medicine and make-up, and it is usually the cheaper route once you count the repairs you don’t end up repeating.

Building Defects We Investigate in Liverpool
We investigate defects in every age and type of property, from Georgian townhouses to new-build apartments. These are the problems that most often land on our desk:
Damp, Condensation and Mould
Much ‘rising damp’ in Liverpool homes is misdiagnosed,we identify the real cause before you pay for tanking or injection you may not need.
Cracking, Movement and Structural Defects
From cosmetic cracks to settlement, subsidence and wall-tie failure,with in-house structural engineering when the structure itself is in question.
Timber Decay, Dry Rot and Wet Rot
Rot in floors, joists and roof timbers. We trace the moisture source driving it and confirm what genuinely needs replacing.
Roofs, Gutters and Water Ingress,
Slipped slates, failed flat roofs and hidden parapet gutters,inspected by high-level drone surveying where access is difficult
Facades and External Fabric
Spalling brick, eroding sandstone and failed repointing on walls that take wind-driven rain off the Mersey

You receive a written building defect report setting out what is wrong, why, and what to do next, in priority order.
Building Pathology FAQs
Building pathology is the investigation and diagnosis of building defects, establishing why a problem such as damp, cracking or decay is happening by examining the building’s construction, materials, environment and use, so that repairs address the cause rather than the symptom.
A building pathologist (at ASG, a chartered surveyor with defect-diagnosis expertise) inspects the defect and surrounding fabric, identifies the mechanism causing it, assesses severity and urgency, and recommends remedial action, including further testing or specialist input only where it genuinely adds value.
A specific defect survey is a focused inspection of one known problem, a damp wall, a crack, a leak, rather than the whole property. It is usually quicker and more economical than a full building survey, and produces a deeper report on that single issue
It depends on the property, the defect and the access required, so we don’t publish a one-size-fits-all price. Describe the problem and we will confirm a fixed fee before you book, no surprises afterwards
We work across Liverpool, Merseyside, Wirral, Sefton, St Helens, Warrington, Cheshire, Manchester and the wider North West from our Liverpool office.
