RICS Level 3 Building Survey in St. Asaph

A Level 3 survey is the most detailed visual inspection available through the standard RICS route. Our surveyor checks the visible structure, roof coverings, chimney stacks, walls, floors, ceilings, joinery and all accessible loft and sub-floor areas, then comments on the condition of materials and any signs of active or historic deterioration. In St. Asaph, that often means a close look at sandstone, limestone, brick, slate and older mortar, because the town’s older stock includes the cathedral fabric, the 1770 bridge and houses that grew out of a much smaller core. If a defect looks serious, we say so plainly.

The report also explains what repairs are needed, how urgent they are, and what may happen if they are left for later. That practical advice matters on properties that have seen flood water from the River Elwy, especially where damp has reached joists, skirtings or lower wall finishes. A Level 3 survey does not involve destructive opening up, lifting carpets, cutting into walls, drainage CCTV or service testing, so it is not a replacement for specialist inspections when a fault needs proof. It is the survey that helps you decide where the risk really sits before you commit to the price.

Older homes in LL17, especially those near the cathedral area or on the edges of the town where detached properties sit on larger plots, can hide a mix of traditional building methods and later alterations. We look for slipped slate, perished pointing, roof spread, damp staining, condensation, uneven floors and movement around openings. If the property has a cellar, a timber floor over a ventilated void, or later extensions joined onto older walls, those areas get attention because they often produce the most expensive surprises. The point is not to frighten you, it is to show you what the building is telling us.

• Accessible loft and roof timbers
• Sub-floor voids and joists
• Internal walls, ceilings and floors
• External masonry, joinery and drainage routes

St. Asaph has a building stock that rewards a careful eye. The cathedral uses red sandstone with grey limestone, while other historic buildings in the area show yellowish sandstone, purple sandstone and 19th-century red brick with sandstone dressings and Dinorwic slates. Those materials age in different ways. Sandstone can decay at exposed faces, mortar joints can open up, and old slate roofs can start to leak at valleys, abutments or chimney junctions.

Flood history is the big local issue. The River Elwy has caused serious events, including November 2012, when 322 homes, 32 businesses and 70 caravans were affected, and Storm Ciara in February 2020, which brought more flooding around the River Elwy, River Ceidiog, River Ystrad and River Clwyd. Natural Resources Wales has completed flood risk management works, and current defences are designed to protect against a flood with a one in 75 chance of happening in any given year, but overtopping is still possible in extreme events. That is why a Level 3 survey here needs to think beyond the walls and into the ground conditions around the building.

Age and alteration are the other common threads. Many properties date from the 16th and 17th centuries, the town expanded in the 19th and 20th centuries, and the local list includes buildings such as The Old Deanery, The Red Lion Public House, St. Asaph Bridge and the former Bodfari New School, now a house, built in 1858-59. In that mix, we often see damp penetration, timber decay, movement at old and new junctions, crumbling pointing, failed render and roof defects around older chimney stacks. If a house has already taken water, a surveyor will look closely at hidden floor damage and the signs of drying that never quite finished.
