HERITAGE DEFECT SURVEYS
Expert Insight to Protect and Preserve Historic Properties
Preserving the integrity of a historic or listed building requires more than just repairs; it demands a deep understanding of traditional construction, sensitive materials, and conservation best practices. At AMS Surveys, our specialist Heritage Building Defect Surveys uncover structural issues, damp, timber decay, and roof problems that could threaten the long-term stability of your property.
Whether you're planning repairs, applying for listed building consent, or investigating long-term deterioration, we provide detailed assessments that align with heritage conservation standards.
STRUCTURAL INVESTIGATION FOR HERITAGE BUILDINGS
Sensitive assessment of movement and structural integrity
Older buildings often show signs of movement, but not all cracks are critical. Our structural inspections are tailored to the unique construction methods and materials found in listed and historic buildings. We evaluate issues like subsidence, settlement, bowing walls, and historic repairs, always considering their context and significance.
We assess:
-
Historic and recent structural cracking
-
Movement in load-bearing walls, lintels, and arches
-
Bowing or leaning walls (common in timber frame or masonry buildings)
-
Floor deflection and ceiling movement
-
Past structural interventions and their effectiveness
Our reports are written with an understanding of heritage conservation principles, helping clients plan remedial works that are both effective and appropriate in the context of listed status or historic value.


HERITAGE DAMP AND TIMBER SURVEYS
Diagnosing moisture and decay without damaging the fabric
Damp is one of the most common and misunderstood issues in historic buildings. Modern interventions can often worsen the problem. Our damp and timber surveys are carried out using non-invasive techniques and an understanding of how traditional buildings “breathe”.
We investigate:
-
Rising damp caused by ground moisture and failed plasters
-
Penetrating damp from roof defects or poor detailing
-
Ventilation and condensation risks in solid-walled buildings
-
Rot and insect damage in original timbers (joists, beams, rafters)
-
Past chemical treatments and inappropriate materials
Reports include moisture readings, condition ratings, and conservation-led recommendations. We help you resolve damp issues sympathetically, without harming the building’s historic integrity.
TAILORED SUPPORT FOR CONSERVATION PROJECTS
Each survey is written to support heritage-led planning, building consent applications, or remedial design. We work in line with Historic England guidance, local conservation policies, and best practice in traditional building repair.

HERITAGE DRONE ROOF SURVEY
Preserving the first line of defence in historic structures
Roofs are vital to the long-term health of heritage buildings, yet often neglected until major damage occurs. We provide roof condition surveys for slate, tile, lead, and thatched systems, combining visual inspection with safe access methods (including drones where permitted).
We assess:
-
Failed or displaced slates, tiles, and flashing
-
Sagging roof lines and timber spread
-
Water ingress, ceiling staining, and internal decay
-
Valley and parapet issues are typical in older buildings
-
Structural integrity of trusses, purlins, and rafters
Whether you're applying for Listed Building Consent or planning sensitive repairs, our surveys provide clear, conservation-aware insight supporting both urgent repairs and long-term maintenance planning.
