RICS Level 3 Building Survey in CH5

Our RICS Level 3 Building Survey provides an exhaustive examination of the property's condition, identifying defects, potential future problems, and urgent repairs. The inspection covers all accessible areas of the building, including the roof structure, walls, floors, ceilings, doors, and windows. Our inspectors assess the condition of built-in appliances where safe to do so, and examine both the interior and exterior of the property. For properties in CH5, this includes checking for issues common to local housing stock, such as dampness resulting from the clay-rich soils in Flintshire or damage from historical mining activity.

The survey report includes a clear rating system for each element inspected, ranging from "not inspected" through to "urgent repairs necessary." We provide practical advice on maintenance matters that will help protect your investment long-term, along with estimated costs for any repairs identified. For buyers purchasing properties in new developments like Dutton Fields or Hollybrook Park, we can identify any snagging issues that builders should address before completion. The report also includes a market valuation, which proves invaluable during price negotiations when defects are discovered. This is particularly useful in the CH5 market where 371 properties sold in the last year and competition for good properties remains strong.

Properties in CH5 face specific structural challenges that our surveyors know to look for. The clay soils underlying much of Flintshire cause shrink-swell movement that can damage foundations, particularly during periods of drought followed by heavy rainfall. We check for signs of this type of movement, including cracking to walls and doors that stick or fail to close properly. For properties in areas with historical mining activity, our inspectors assess the risk of subsidence and advise on any further investigations that may be necessary. The comprehensive nature of the Level 3 survey means you receive a complete picture of the property's structural integrity before you commit to the purchase.

Our inspection extends beyond the main building to include garages, outbuildings, and boundary walls where accessible. We assess the condition of drainage systems, which is particularly important in CH5 where defective drains are a common cause of subsidence damage. We examine the property's position relative to flood risk areas, noting that parts of Deeside, Connah's Quay, and Saltney are projected to be below the annual flood level by 2030. The detailed assessment we provide gives you confidence in your property decision and valuable ammunition for price negotiations if significant issues are identified.

Properties throughout the CH5 postcode area face several structural risks that our Level 3 Survey specifically addresses. The most significant is clay shrink-swell, a geological hazard that affects buildings across Flintshire due to the clay-rich soils underlying the region. When periods of dry weather are followed by sustained rainfall, the clay expands and contracts, causing foundations to move. This movement can result in cracking to walls, particularly diagonal cracks around door and window frames, and can cause floors to become uneven. Our inspectors are experienced in identifying the signs of this type of movement and can advise on whether remedial works are necessary. This is particularly relevant given that the zone of seasonal moisture fluctuation where shrink-swell occurs typically extends 1.5-2 meters underground but can reach up to 5 meters in some conditions.

Historical coal mining presents another significant concern for properties in CH5. Flintshire has an extensive legacy of underground mining, and while many older workings have stabilized, shallow coal seams can still pose risks. The Coal Authority reported six mining-related subsidence incidents in Flintshire between May 2022 and January 2025 alone. Our surveyors assess the likelihood of mining-related movement based on the property location, historical records, and visible signs of damage. For properties in higher-risk areas, we may recommend a more detailed investigation or consultation with the Coal Authority. This is especially important for properties in Buckley, where local brick production history indicates extensive clay working.

Flood risk is a genuine consideration for properties in CH5, particularly those in low-lying areas near the Dee Estuary. Parts of Deeside, Connah's Quay, Saltney, and surrounding areas are projected to be below the annual flood level by 2030 due to rising sea levels according to Climate Central data. Areas including Deeside Industrial Park, Garden City, Sealand, Queensferry, and Sandycroft are all identified as being at risk. Our inspectors check for evidence of previous flood damage, assess the property's position relative to flood zones, and evaluate the effectiveness of any existing flood mitigation measures. Combined with the risk of surface water flooding during heavy rainfall events, this makes the detailed assessment provided by a Level 3 Survey particularly valuable for CH5 properties.

Beyond these primary risks, our surveyors also check for issues specific to the local construction methods used in Flintshire properties. Many older buildings in the area were constructed using a combination of flint, chalk, brick, and stone, with brick becoming increasingly prevalent from the 18th century onwards. In timber-framed cottages, brick walls were sometimes laid in elaborate patterns, while in clay areas like Buckley, brick was used alone with red clay roof tiles. Our inspectors understand these traditional construction methods and can identify related defects such as deterioration of mortar pointing, structural issues with timber frames, and problems arising from inappropriate modern repairs that can trap moisture and cause decay.

• Clay shrink-swell subsidence
• Historical coal mining movement
• River and coastal flooding
• Surface water flooding
• Ground stability issues

The CH5 property market presents unique challenges that make a comprehensive Level 3 Survey particularly valuable. With 39% of properties in the area being detached and 34% semi-detached, many homes are substantial investments that warrant thorough investigation before purchase. The average price of £223,816 means that identifying even minor defects can provide significant negotiating leverage, while discovering major structural issues could save you from a costly mistake.

The diverse age profile of properties in CH5 also necessitates careful surveying. From Victorian terraces in the centres of Connah's Quay and Buckley, through post-war semi-detached housing, to modern new builds at Hollybrook Park and other developments, each era brought different building techniques and materials. Our surveyors understand these construction methods and can identify age-related defects that might not be apparent to a buyer. For instance, properties built before 1900 may have timber frames that require specialist assessment, while post-war properties may have issues related to cavity wall tie corrosion.

The economic significance of the Deeside Industrial Park to the CH5 area also affects the property market. With major employers including Tata Steel headquartered near Dutton Fields, and excellent transport links via the A55 and Deeside Parkway railway station, the area attracts workers seeking to live locally. This drives demand for housing but also means that properties may have been subject to different standards of maintenance depending on whether they were owner-occupied or rented. Our thorough survey helps you understand the true condition of any property you are considering purchasing in this active market.

Additionally, with parts of CH5 falling within conservation areas including Hawarden, and over 1,000 listed buildings in Flintshire, many properties in the area have special protections that affect what you can and cannot do after purchase. Our surveyors can identify any conservation or listed building issues that may impact your plans for the property, ensuring you understand the full implications of your purchase before you commit.
