RICS Level 3 Building Survey in Coleraine

A Level 3 survey is the most detailed visual inspection we offer on a home in Coleraine. Our RICS-qualified building surveyors look at all accessible parts of the property, including the roof coverings, loft, ceilings, walls, floors, joinery, basement or sub-floor spaces and visible service runs. On a property near The Diamond or along Church Street, that means we are not just checking for obvious wear. We are looking at how the building was put together, which materials were used, and where those materials are starting to fail.

The report sets out the condition of the property in plain language. It explains what is wrong, why it matters, what repair work is likely, and what could happen if the defect is left alone. A cracked render finish on a Waterside terrace may be minor, while persistent damp staining in a listed property near the Conservation Area can point to a more expensive issue beneath the surface. That is where the Level 3 report earns its keep.

A survey of this type does not involve destructive opening up, lifting carpets, cutting into plaster, carrying out drainage CCTV or testing the electrical, gas or heating systems. Those jobs need separate specialists if the surveyor sees a reason to recommend them. On older homes around the River Bann, that split matters, because a building survey can identify a likely drain leak or timber decay, but it will not probe inside the pipework or the circuit board itself.

Coleraine's older core around The Diamond, Church Street and Waterside includes Victorian and Edwardian commercial buildings, civic buildings and some Georgian homes, so a Level 3 survey often starts with the way the walls were built. Traditional solid masonry is common in the older stock, with stone, red brick and painted render showing up across the town centre and in the Conservation Area. Those buildings can look solid from the road, yet hidden defects often sit in the junctions, the roof void or the ground floor.

Dampness is one of the main issues we see in older homes in Coleraine, especially where there is failed pointing, cracked render, blocked gutters or poor ventilation in a cellar or under-floor void. Timber decay follows close behind. Wet rot, dry rot and woodworm often turn up in roofs, floors and joinery where moisture has been left to sit, and that matters more on a pre-1919 terrace than on a newer estate house off Castlerock Road. Slate and tile roofs also need care, because worn coverings, loose flashings and tired leadwork can let water in for years before a buyer spots the damage.

The ground conditions are mixed. Basalt bedrock from the Antrim Lava Group is generally stable, but glacial till with clay content can bring a moderate to low shrink-swell risk in some spots, particularly where drainage is poor or mature trees are nearby. Flooding is another local factor. The River Bann creates fluvial risk for homes close to the riverbanks, while surface water can build up in low points after heavy rain. There is no significant deep coal mining history here, so mining subsidence is not the main concern, but clay movement, leaking drains and flood water still deserve a close look.

• Rising damp and penetrating damp
• Timber rot and woodworm in roof or floor timbers
• Slate, tile and leadwork failure
• Render cracking and mortar loss
• Localised movement linked to clay pockets or drainage issues
