RICS Level 3 Survey in Alnham

Alnham’s housing stock is very different from modern development. The hamlet lies at the foot of the southern outliers of the Cheviot Hills, where older homes are usually built from local stone. That geology, mainly Devonian granite and andesite lava, shapes how these properties were put together and the sorts of defects we expect to find. Our inspectors have long experience with these traditional buildings, and we know how age, materials and the local environment work together to create both strengths and weaknesses in the structure.

Seven listed structures sit within the village, among them the Grade I listed Church of St Michael and All Angels with its Saxon foundation, and the Grade II* listed Tower House, a 14th-century pele tower that speaks to the area’s border history. The medieval settlement at Alnham is also a scheduled monument, which tells its own story of long occupation. Many homes here carry those same historic traits, with exposed stonework, traditional brick fireplaces and original architectural details that need specialist attention during a survey.

Most properties in Alnham fall into the pre-1900 bracket, with the War Memorial Hall (built in 1921) described as reportedly the only new building put up in the 20th century. In practice, that leaves the bulk of the housing stock as pre-1919, which brings a different set of concerns for buyers. Our Level 3 surveys look closely at those age-related issues, studying how years of weathering, settlement and renovation have affected structural integrity. The hamlet’s remote setting also means plenty of homes have had only limited modern updating, and our survey will pick that up.

• Pre-1919 construction
• Traditional solid stone walls
• Slate or stone flag roofing
• Converted agricultural buildings

Our inspectors pay close attention to environmental factors that are particular to Alnham. The River Aln runs eastward through the hamlet from its source in the Cheviot Hills, so properties close to the river may carry flood risk that deserves careful investigation. Specific flood risk mapping for Alnham was not available, but the river’s route through the village centre means a detailed flood risk assessment should be part of the buying process in certain spots. Our surveyors will note how near the property is to the river and whether any flood mitigation measures are already in place.

The local geology also affects ground conditions. The Cheviot Hills are made up mainly of resistant granite and andesite lava, so clay-related shrink-swell risk is likely to be low, though we still examine foundations and ground conditions in full. We look for settlement or movement that might point to issues with the soil below or past activity on the site. Alnham sits outside the main Northumberland Coalfield area, so mining subsidence is highly unlikely to be a concern, but we still check foundations for movement or instability that could have other causes.

Properties in Alnham can also show the kind of wear that is common in rural locations, from deterioration in external joinery to weathering of stonework and long exposure to the elements. Our inspectors record these issues in detail, so you can weigh up immediate repairs alongside the longer-term upkeep traditional homes in this area tend to need. The hamlet’s small population of approximately 245 residents (2011 Census) and its agricultural economy mean many homes may have seen limited ongoing maintenance over the years.

• Foundation and ground conditions
• Stonework deterioration
• Drainage and gutters

Alnham brings together a set of factors that make a thorough RICS Level 3 Survey especially important for any purchase in the area. The properties face challenges that are quite different from those found in modern housing, and a basic visual inspection will not give you enough to make a sound decision about the investment. Much of the housing stock is old, so defects may be hidden behind period features or have developed slowly over decades without being dealt with.

Traditional solid stone walls are durable, but they do not have the damp-proof courses found in modern construction. That leaves them open to rising damp, particularly where ground levels have been raised over time or an existing damp-proof course has failed. Slate and stone flag roofs, while full of character, need specialist inspection to judge their present condition and how long they are likely to last. Our surveyors understand these old methods of construction and can spot issues that a less experienced inspector might miss.

Quite a few homes in Alnham began life as agricultural buildings, and those conversions often bring non-traditional construction methods that call for close inspection. Be it a converted barn or a former farm building, our Level 3 Survey looks at the quality of the conversion work, any new structural elements and whether the building meets the right standards for residential use. That extra detail matters in a place with such a varied property stock.

Our experience surveying homes across this part of Northumberland shows a few defect patterns that Alnham buyers should know about. Dampness is one of the issues we most often find in older stone properties. Rising damp is common where damp-proof courses have failed or are missing, while penetrating damp can come through degraded pointing, faulty gutters or damaged flashings. Condensation is another problem, especially in properties with poor ventilation and solid walls that do not have cavity insulation. The traditional construction methods used in Alnham make these homes particularly prone to damp-related issues.

Timber defects are another regular feature in many traditional properties. The common furniture beetle, or woodworm, often attacks structural timbers in older buildings, while both wet and dry rot can take hold where moisture has been present for a long time. Our surveyors inspect all accessible timber elements, including floorboards, joists, roof timbers and structural frames, and they record any sign of infestation or decay. In older homes, timber condition can deteriorate badly before the signs become obvious, so professional assessment matters.

Roofs need close attention in Alnham properties. The traditional slate and stone flag roofs found on most buildings here can suffer age-related deterioration, such as cracked or missing tiles, failed leadwork and worn ridge tiles. Chimney stacks often show weathering and mortar decay, while gutters and downpipes may be corroded or blocked, leading to overflow and water entering the building fabric. Our inspectors assess all of this carefully, note the condition and recommend the right repairs.

Many homes in Alnham will also have outdated electrical, plumbing and heating systems that need bringing up to current standards. Our survey will flag any concerns with those installations and recommend further checks by qualified specialists where needed. On top of that, older properties often lack modern insulation, so thermal performance can be poor and energy costs higher, which matters when you compare them with current living standards.

• Rising and penetrating damp
• Woodworm and timber rot
• Roofing deterioration
• Chimney defects
• Window and door joinery decay
• Outdated services (electrical, plumbing, heating)
