RICS Level 2 Home Survey Houghton

Houghton-le-Spring presents a unique set of challenges for property buyers. The town has a rich industrial heritage dating back to the 19th century, with Houghton Colliery operating from 1823 to 1981 and Philadelphia Colliery closing in 1985. This mining history means that many properties in the area are built on ground with potential for subsidence, and our surveyors pay particular attention to signs of movement, cracking, or structural instability that could relate to historical or ongoing ground movement. We have inspected properties across all parts of the town, from the Victorian terraces near the town centre to newer developments on the outskirts, and we know exactly what to look for when assessing a property in this area.

The local geology adds another layer of complexity. Houghton-le-Spring sits on Magnesian Limestone, and the underlying Coal Measures rocks have created widespread evidence of fissuring and structural damage in the area. Our inspectors are trained to identify the tell-tale signs of this type of ground movement, including cracks in walls, uneven floors, and misaligned doors and windows. We also check for the effects of shrink-swell clays, which can cause significant damage during periods of hot weather when clay soils lose moisture and contract. During our inspections, we commonly see the effects of these geological factors, particularly in properties built on the higher ground around St. Michael's and All Angels Church and along the Newbottle Road area.

The predominant housing stock in Houghton-le-Spring includes Victorian and Edwardian terraced properties built from local sandstone and red brick, many with solid walls that pre-date modern damp-proof courses. These older properties commonly suffer from rising damp, penetrating damp, and condensation issues, particularly where original features like timber sliding sashes and Welsh slate roofs have deteriorated. Our Level 2 surveys include thorough assessments of roof condition, damp readings, and timber integrity. We use professional moisture meters to identify damp problems and can determine whether they are caused by rising damp, penetrating damp, or condensation, which is essential for recommending the correct remediation.

Many properties in the area also have significant historic alterations, including loft conversions and extensions that may not comply with current Building Regulations. Our surveyors check for signs of inadequate insulation, missing fire stops, and structural modifications that could affect the integrity of the property. We also assess the condition of any outbuildings, garages, and boundaries, ensuring you have a complete picture of what you are purchasing.

While Houghton-le-Spring is not generally considered a high flood risk area, certain pockets do experience surface water flooding, particularly in western and northern parts of the town and in Hetton-le-Hole. Our surveyors inspect drainage systems, gutters, and downpipes, and note any evidence of water ingress or dampness that might relate to poor drainage or flooding history. We pay particular attention to properties built on clay soils, which can lead to drainage problems and standing water during periods of heavy rainfall.

Specific flood warning areas exist along the Moors Burn watercourse, affecting properties around Sedgeletch Road, Cedar Terrace, and the Rainton Bridge area. If the property you are purchasing falls within or near these zones, we will highlight this in the survey report and recommend that you consult the Environment Agency flood maps for more detailed information. Properties in the Sedgeletch area and near the old sewage works should be treated with particular caution, and we always recommend that buyers check the latest flood risk information before proceeding.

The survey also checks the gradient of the land around the property and the condition of drainage systems, which are particularly important given the clay soils in the region that can lead to standing water and moisture problems. We assess the position of gutters and downpipes, the condition of drainage channels, and whether the ground slopes away from the property effectively. Properties on the lower ground around Rainton Bridge and the Moors Burn valley are especially susceptible to drainage issues, and we have seen numerous cases where poor drainage has led to significant damp problems.

Based on our experience surveying properties across Houghton-le-Spring, several recurring issues appear frequently in our reports. Damp problems are perhaps the most common, affecting both older solid-walled properties that lack modern damp-proof courses and newer properties where defects in brickwork, gutters, or flashing have allowed water penetration. Our surveyors use moisture meters to assess damp levels and identify the source of any moisture problems. We commonly find penetrating damp caused by defective gutters or porous brickwork, particularly on properties exposed to prevailing winds from the west. Rising damp is also frequently seen in older properties without a damp-proof course, especially where the ground level has been raised over the years.

Roof defects are another frequent finding, particularly on older properties with original Welsh slate roofs that have deteriorated over decades. Missing or broken tiles, deteriorated ridge mortar, and failed flashings around chimneys can lead to leaks and water damage. We also commonly find issues with outdated electrical installations in properties that have not been updated since they were built, posing fire risks that need addressing. Many Victorian and Edwardian properties in the area still have their original fuse boxes and wiring, which would not meet current electrical safety standards. We recommend that buyers obtain a qualified electrical inspection in addition to the survey for any property with old electrical installations.

Structural movement related to the area's mining history and the underlying geology is a serious concern that our surveyors are trained to identify. This includes cracks in walls, doors that stick or do not close properly, and uneven or sagging floors. While many instances of movement are historical and have stabilised, some properties may show ongoing signs of movement that require further investigation and potentially specialist structural engineering advice. We have seen properties throughout Houghton-le-Spring with significant crack patterns that relate to historical mining activity, and we know how to distinguish between minor settlement cracks and more serious structural issues that might require further investigation.

Other common defects we find include deteriorated timber windows and doors, particularly the original timber sliding sashes that are common in older properties. These often have rotting timber frames, broken cords, and poor seals that lead to drafts and heat loss. We also frequently identify inadequate insulation in loft spaces, particularly in properties that have not been updated since construction. Given the rising cost of energy, this can have a significant impact on the ongoing cost of heating the property. Our survey report will highlight all these issues and provide practical advice on how to address them.
