RICS Level 2 Survey in Monmouth

Monmouth's housing stock presents unique challenges that make a professional survey essential. The town centre features numerous period properties constructed from local Old Red Sandstone, many dating back to the Georgian and Victorian eras. These historic homes, while characterful, often conceal issues such as deteriorating stonework, aging roof structures, and outdated electrical systems that aren't visible during a standard viewing. Our surveyors have specific training in assessing traditional stone construction, understanding how weathering affects local sandstone, and identifying the tell-tale signs of water ingress that plague older properties in this part of Wales.

The conservation area covering much of Monmouth's historic centre contains many listed buildings requiring specialist consideration. Our inspectors understand the specific construction methods used in traditional Welsh properties and know what to look for when assessing properties built with solid walls, traditional lime mortars, and historic roofing materials like slate and clay tiles. We've surveyed dozens of properties along Agincourt Square, Church Street, and the historic Monnow Street area, giving us firsthand knowledge of the common issues affecting these historic homes.

Properties near the River Wye and River Monnow face potential flood risk, making environmental assessments an important part of the survey process. Our chartered surveyors evaluate drainage, proximity to watercourses, and any evidence of previous flooding that could affect your investment. We check for flood marks, water staining, and damp patterns that might indicate past water ingress - particularly important for properties in low-lying areas near the river confluence.

Beyond the historic centre, Monmouth has seen modern development on the outskirts, with new builds requiring different assessment approaches. Even newer properties can hide defects from rushed construction or cutting corners by developers. Our thorough visual inspection covers all accessible areas, regardless of property age, ensuring you know exactly what you're purchasing.

Understanding how Monmouth's properties were built helps explain the common issues we find during surveys. The predominant building material in the historic town centre is Old Red Sandstone, quarried locally from the Devonian-age deposits that underlie much of this part of Wales. This distinctive red-brown stone gives Monmouth its characteristic appearance but presents specific challenges. Sandstone is relatively soft and porous, meaning it can deteriorate when exposed to decades of Welsh rainfall and frost cycles. Pointing between stone blocks often uses lime mortar, which is softer than modern cement and can wash out over time, allowing water penetration.

Many Victorian and Edwardian properties in Monmouth were built using solid brick walls rather than the cavity wall construction that became standard from the 1930s onwards. Solid walls have no built-in damp-proof course, making them vulnerable to rising damp unless a physical DPC was installed or the property has been professionally treated. Our surveyors know to check for signs of damp at low levels, particularly in ground-floor rooms where moisture from the ground can rise through porous brickwork.

Roofing across Monmouth typically uses natural slate, either imported Welsh slate or older local varieties. While slate is durable, individual tiles can slip or crack, and the leadwork around chimneys and valleys deteriorates over time. Traditional mortar used for bedding ridge tiles often fails after 50-60 years, leading to loose ridge tiles that pose a safety risk. Our inspectors thoroughly examine roof slopes from both inside the loft and ground-level external observation, noting any defects that require attention.

The geology beneath Monmouth includes clay deposits, particularly in areas away from the river gravels. Clay soils shrink and swell with moisture content, which can cause foundation movement in properties with shallow footings - a particular concern for older buildings. Our surveyors look for signs of structural movement such as cracking, door and window binding, and uneven floors that might indicate foundation issues.

Our surveyors regularly identify several recurring problems in Monmouth homes. Rising damp is particularly common in older properties with solid walls, where the original damp-proof course may be missing or deteriorated. In properties without a physical DPC, moisture from the ground rises through capillary action, causing damp patches at low levels on walls. This affects not only the appearance of decorations but can also lead to timber decay and health issues from mold growth. Our survey includes systematic damp testing using a moisture meter at various heights to assess the extent of any damp problems.

Penetrating damp often affects stone-built properties where pointing has weathered over decades, allowing water ingress during heavy rainfall common to the Welsh borders. The prevailing south-westerly winds drive rain against exposed walls, and when mortar joints have deteriorated, water penetrates into the wall fabric. This can lead to internal damp patches that worsen during winter months. Our surveyor will examine external walls carefully, noting any areas of defective pointing, cracked render, or missing stone pieces that could allow water ingress.

Timber defects represent another significant concern, especially in properties with original wooden windows, floorboards, and roof structures. Woodworm and wet rot can cause extensive damage before becoming visible, making our detailed timber inspection essential. We check window frames for soft spots indicating rot, examine floorboards for signs of woodworm exit holes, and inspect roof timbers for any evidence of beetle activity or fungal decay. Many Monmouth properties also have older roofing using traditional slate, which can suffer from slipped or broken tiles, deteriorating leadwork, and failed mortar on ridge tiles.

Outdated electrical systems feature frequently in properties built before the 1980s. Original wiring may not meet current regulations and could pose a fire risk, particularly if overloaded with modern appliances. We visually inspect the consumer unit and wiring where accessible, noting any obvious concerns such as old-style fuse boxes, fabric-covered cabling, or cracked socket fronts. Our report will recommend a qualified electrician to conduct a fuller inspection if we identify potential issues.

• Rising and penetrating damp
• Timber decay and woodworm
• Roof deterioration
• Outdated electrical systems
• Pointing and stonework erosion

Monmouth's location at the confluence of the River Wye and River Monnow creates genuine flood risk for properties near these watercourses. The town has experienced significant flooding events in the past, with the River Monnow particularly prone to bursting its banks during periods of heavy rainfall in the upper catchment areas. Properties in low-lying areas near the rivers, including parts of the town centre and residential areas along the river valleys, face potential flood damage that could affect both the property value and your ability to obtain insurance.

Our chartered surveyors assess flood risk as part of every Level 2 Survey, noting the property's proximity to watercourses and looking for evidence of previous flooding. We examine internal walls for water staining at heights that might indicate past flood events, check for modern flood resilience measures such as non-return valves on drainage, and note the condition of any existing flood defenses. For properties in known flood zones, we recommend checking the Natural Resources Wales flood maps for detailed risk information.

While flood risk is concentrated near the rivers, Monmouth's underlying clay geology can also create drainage challenges for some properties. Clay soils drain slowly, meaning surface water may persist after rainfall. Properties with poor drainage can suffer from damp problems even without river flooding. Our survey includes assessment of gutters, downpipes, and surface water drainage, noting any blockages or defects that could lead to water-related issues.
