RICS Level 2 Survey in BB1

Our surveyors inspect properties across BB1 and the wider Blackburn area regularly, and certain defect patterns recur across Blackburn's various housing eras. Victorian terraces built for mill workers, interwar semi-detached streets and post-war housing estates each present their own set of risks.

Victorian terraced properties in BB1 were built using back-to-back or through-terrace layouts that were efficient but presented specific damp challenges. Solid brick walls without cavities rely on the property being continuously heated and the pointing being well maintained to prevent moisture penetration. After a century of use, many Victorian BB1 terraces show deteriorating mortar joints, especially on north and east-facing rear elevations. Our surveyors check pointing condition on all accessible elevations and use calibrated damp meters at regular intervals across ground-floor walls to detect moisture that may not yet be visible to the naked eye.

Roof coverings are one of the most consistent sources of condition rating 2 and 3 issues on older BB1 properties. Original clay plain tiles or Welsh slate were used on most Victorian terraces in the area, and many roofs are now well past their expected service life without full replacement. Our inspectors assess roof coverings from ground level using binoculars, checking for slipped, cracked and missing tiles, deteriorated ridge mortar, failed lead flashings and blocked valleys. Where a loft hatch is accessible, we inspect the roof structure from inside to look for signs of water ingress, rafter movement or inadequate ventilation.

• Deteriorating pointing on solid brick Victorian walls allowing moisture penetration
• Aged roof coverings on pre-1945 clay-tiled or slate roofs past expected service life
• Outdated fuse-board wiring in properties not comprehensively rewired since the 1970s
• Failed chimney stack mortar beds and flashings on multi-chimney Victorian terraces
• Suspended timber ground floors with blocked subfloor ventilation causing timber decay
• Older cast-iron soil and waste pipes with joint failures causing persistent damp
• Rising damp in older properties where original damp-proof course has failed or was never installed
• Single-skin boundary walls and outbuildings in a state of significant deterioration

Post-war semi-detached properties in BB1 built between 1945 and 1975 present different risks. These homes used cavity wall construction, which was an improvement over solid walls, but early cavities were often narrow and some have been retrofitted with insulation that can act as a moisture bridge if the installation was poorly carried out. Our inspectors check for damp staining, cold bridging and any evidence of cavity insulation-related issues on all post-war cavity wall properties we survey in the BB1 area.

Our RICS Level 2 Survey - the product that used to be sold as a HomeBuyer Report - is a comprehensive visual inspection of all accessible parts of a property, delivered as a standardised RICS report. It is appropriate for most conventional BB1 properties in reasonable condition.

Our inspectors systematically work through the following elements on every BB1 property they survey:

• Roof structure and covering: ridge tiles, verge mortar, flashings, guttering and downpipes assessed from ground level with binoculars, with loft inspection where access is available
• External walls: all elevations checked for cracking patterns, pointing condition, damp staining, cement repointing over lime substrate, and evidence of movement
• Chimneys: stack condition, pointing, flaunching and flashings assessed on every chimney present
• Windows and external doors: frame condition, drainage channels, lintel condition above each opening and seal integrity on double glazing
• Internal walls, floors and ceilings: calibrated damp meter used on all ground-floor walls and any wall adjacent to a bathroom or kitchen
• Roof space: structural integrity, ventilation, insulation coverage, evidence of water ingress past or present, and pest activity
• Services: visual inspection of the consumer unit, visible plumbing, heating system and soil and waste drainage with recommendations for specialist testing where condition is unclear
• Site and grounds: boundary walls and fencing, drainage gullies, paths and any evidence of surface water pooling

Each element receives a condition rating of 1, 2 or 3. Rating 1 means no repair is needed at present. Rating 2 means repairs or further investigation are needed but are not urgent. Rating 3 means urgent repair or immediate specialist attention is required. Our written explanations accompany each rated item, along with typical cost ranges for rated 2 and 3 defects so you have a practical basis for negotiation or budgeting.

For BB1 properties showing significant structural movement, non-standard construction, or extensive alterations, our surveyor will advise at quote stage whether a RICS Level 3 Building Survey would give you better value. We do not push buyers into a more expensive product unnecessarily, but we will always tell you directly when the Level 2 scope is not sufficient for a particular property.
