RICS Level 3 Building Survey in Caernarfon (LL55 1)

Caernarfon's unique character means that properties here often present challenges that require the detailed attention only a Level 3 Survey can provide. The town boasts a remarkable concentration of listed buildings, particularly within the historic walled town, with many properties on streets like Market Street, High Street, Castle Street, and Bank Quay dating back centuries. These historic structures, while charming, can hide structural issues that are not apparent during a casual viewing. Our inspectors are experienced in assessing traditional Welsh construction methods, including solid stone walls, lime mortar pointing, and historic roof timbers that may have been in place for generations.

The local geology around Caernarfon also presents specific considerations that our surveyors take into account. While not as susceptible to clay shrink-swell as some parts of the UK, the surrounding area in Gwynedd has a history of mining activity for metals including lead, copper, and gold that can affect ground stability. Historical mine workings can lead to subsidence, particularly over old entrances and workings, and our surveyors investigate any signs of movement or cracking that might be related to these historical workings. Additionally, properties near the River Seiont and the harbour areas, including Bank Quay, may have been affected by past flooding events. Caernarfon Harbour is a designated Flood Warning Area, and records show significant flooding in 1973 affected streets including Bridge Street, Turf Square, Eastgate Street, and Crown Street due to heavy rain and a blocked culvert. Our inspectors pay particular attention to any signs of water damage or damp penetration that could compromise the structural integrity of the property.

Many properties in Caernarfon were constructed using traditional methods that differ significantly from modern building standards. Solid walls without cavity insulation, original timber sash windows, and historic roofing materials like Welsh slate all require specialist knowledge to assess correctly. Our Level 3 Survey provides you with a detailed understanding of these elements and advice on how they perform by today's standards, including recommendations for improving energy efficiency where appropriate. The report also includes specific guidance on any listed building considerations, as many properties in LL55 1 fall within designated conservation areas where alterations may require planning permission from Cyngor Gwynedd.

If you're considering a property in one of the newer developments in the area, such as the Bro Eglwys development in nearby Bethel offering three-bedroom homes with solar PV panels and air source heating, a Level 3 Survey still provides value. Even modern properties can have construction defects that aren't immediately apparent, and documenting the condition for warranty purposes through a professional survey gives you and useful information for any snagging issues.

• Pre-1900 period properties
• Listed buildings
• Properties showing signs of structural movement
• Homes with significant renovation history
• Properties in flood risk areas
• Large or unusual constructions

Properties in Caernarfon, particularly those in the older parts of town within LL55 1, often exhibit specific defects that our Level 3 Survey is designed to identify. Dampness is one of the most common issues found in historic properties, particularly those without modern damp-proof courses. Rising damp can affect ground floor walls, while penetrating damp often manifests around windows, roof verges, and areas where pointing has deteriorated. Our inspectors will assess the extent of any dampness using moisture meters and visual assessment, distinguishing between different types of damp and recommending appropriate remediation, which may involve improving ventilation, repairing gutters, or installing a damp-proof course.

Structural movement is another significant concern in the area. Properties built on older foundations, particularly those with shallow footings on variable ground conditions, can show signs of settlement or movement over time. This may manifest as cracks in walls, uneven floors, or doors and windows that no longer close properly. In Gwynedd, where historical mining activity has left underground workings, our surveyors will also consider the potential for subsidence related to historical mine entrances and workings. While some movement is common in older properties and may be stable, our surveyors will assess whether any movement is active and what implications this has for the property's long-term structural integrity.

The roofing on many Caernarfon properties also requires careful assessment. Traditional slate roofs, while durable and characteristic of the area, can suffer from broken or slipped tiles, deteriorating lead flashings, and rotting battens. Our inspectors will access the roof where it is safe to do so and examine the condition of the covering, the integrity of the structure, and any signs of past or present leaks. Given the age of many properties in the area, we also check for the presence of asbestos in roofing materials and insulation, which was commonly used in buildings constructed before the 1970s.

Electrical and plumbing systems in older properties are also a key focus during our surveys, as many homes in Caernarfon still have original systems that may not meet current safety standards. We examine the condition of consumer units, wiring, and plumbing fixtures, noting any potential hazards that could pose risks to occupants. Outdated electrical systems with old rubber or cloth-covered wiring, or lead pipes in the plumbing, are common findings in period properties and may require upgrading for safety and compliance with current regulations.

While Caernarfon is renowned for its historic properties, new build developments are emerging in the surrounding area. The Bro Eglwys development in nearby Bethel offers modern three-bedroom semi-detached homes with features like solar PV panels and air source heating, priced similarly to properties in the Rhosbodrual area where new builds are listed around £295,000. Properties like these, while modern, can still benefit from a Level 3 Survey to ensure construction quality meets expectations and to document the condition for warranty purposes.

Planning activity in the broader LL55 area remains active, with recent proposals including a development at Mona on High Street within LL55 1 itself, which includes plans for residential flats with affordable housing elements. Even new builds can have defects that aren't immediately apparent, and a professional survey provides valuable documentation of the property's condition at the time of purchase. This is particularly important given the current challenges facing the construction industry, including materials shortages and workforce constraints that can affect build quality across Wales.

For those considering properties in areas that might be affected by future development, such as the proposed housing development at Land North of Y Garnedd in Llanfairpwll which would add 27 affordable dwellings to the area, a survey provides a baseline condition report. Additionally, should the Wylfa Newydd nuclear power project proceed, it's expected to increase housing demand in the Bangor and Caernarfon areas, making it even more important to ensure your property purchase is sound.
