RICS Level 3 Survey Azerley

Azerley and the surrounding fringe of the Yorkshire Dales call for a careful eye from property buyers. A good number of homes here are built in local sandstone or limestone, using traditional solid wall construction rather than modern cavity walls. They have plenty of character, but older buildings often carry long-standing defects that only a detailed inspection will bring to light.

Across this part of North Yorkshire, our inspectors regularly come across the same trouble spots in the local housing stock. Damp is high on the list, especially rising damp in solid-walled properties with poor or missing damp proof courses. In some places the local geology includes clay-rich superficial deposits, which can add to risks of subsidence or heave, particularly where trees sit close to foundations. Where the ground has high shrink-swell potential, we pay close attention to how the foundations are performing.

Older Azerley homes can also suffer from timber defects, and they are not minor ones. Wet rot, dry rot and woodworm infestation can weaken structural elements, especially where prolonged dampness or poor ventilation has been an issue. With our Level 3 survey, we check timber thoroughly, from floor joists to roof structures, including any visible timbers in accessible roof voids.

Roofs matter here, not least because so many local properties are covered in slate or clay tiles. In plenty of cases those coverings are the originals, now reaching the end of their serviceable life. Our inspectors look closely at roof slopes, lead flashing, chimneys and guttering, picking up wear, damage and likely future trouble. In an area with so many older buildings, chimney deterioration is another common finding.

• Damp and moisture penetration
• Timber rot and woodworm
• Roof covering deterioration
• Chimney defects and decay
• Structural movement and subsidence
• Wall construction issues

In Azerley and across the HG4 3 postcode area, property tends to reflect the traditional building methods of North Yorkshire's rural villages. Older cottages often feature local sandstone and limestone walls, laid in random courses with lime mortar that has calcited over decades or centuries. Those methods need to be understood properly, because repairs differ a great deal from work on modern concrete block construction. Our inspectors know these traditional forms of construction and can advise on suitable maintenance.

Solid walls are common in this area, rather than the cavity walls found in newer homes. Before cavity wall construction became widespread in the early 20th century, solid walls were standard, and they deal with moisture and thermal performance very differently. Our inspectors know what to look for, including penetrating damp, salt contamination and render failure. Given the age of many of these properties, original damp proof courses may be missing or no longer effective.

Most roof structures on Azerley's older properties are formed with timber rafters, purlins and ceiling joists, then finished in natural slate or clay tiles. Both materials can last a long time, but only with regular upkeep. Lead flashing at chimneys, valleys and roof penetrations is a recurring weak point, so our survey looks at these areas in detail. We also record the condition of valleys, abutments and any flat roof sections.

Many homes here still have prominent chimney stacks, a reminder of the area's past reliance on open fires and solid fuel heating. Age-related deterioration is common, including brickwork spalling, damaged flaunching and failed leadwork. Our inspectors pay close attention to chimneys because defects there can allow water penetration and lead to internal damage. We also review any remaining flue systems and comment on their condition.

Azerley is inland, so coastal flooding is not the issue, but the River Laver and a number of smaller watercourses still make fluvial and surface water flooding relevant for buyers in the area. Homes in low-lying spots, or properties with a history of flooding, deserve especially close attention during the survey. The River Laver runs through the area and can see increased flow rates during sustained rainfall.

Heavy rainfall can also bring surface water flooding in rural areas, especially where drainage is poor because of local ground conditions. During our inspection, we note any signs of earlier water ingress, damage or flood markers. We can then comment on the property's flood history and say whether further flood risk investigation would be wise. Larger rear gardens and land close to watercourses need particular care.

Ground conditions around Azerley include clay-rich superficial deposits with moderate to high shrink-swell potential. In practice, that means the soil can expand and contract quite markedly as moisture levels change, with possible movement in foundations and the structure over time. Our surveyors are trained to spot the signs, from cracking patterns to problems with the way doors and windows operate.

No major historical mining operations are directly linked with Azerley itself, but parts of the wider Yorkshire region do have a mining past. For that reason, our surveyors stay alert to any sign of earlier mining activity or ground disturbance that could affect structural stability. We also look for evidence of quarrying or mineral extraction on or near the property.
