RICS Level 2 Survey in BB8

Colne grew up as a mill town during the Industrial Revolution, and most properties in BB8 still show that history plainly. The main building form is stone terraced housing, put together from local millstone grit quarried from the Pennine hills above the town. Built fast and in large numbers to house mill workers from the 1850s through to the early 1900s, these homes vary a lot in build quality, street by street and even decade by decade.

Our surveyors regularly identify these issues in BB8 terraces and semi-detached properties:

• Damp penetration through solid stone walls, particularly on north and west-facing elevations exposed to Pennine rainfall averaging over 1,100mm per year
• Chimney stack deterioration - many BB8 properties have multiple original chimney stacks requiring repointing, flashing replacement, or partial rebuilding
• Roof covering condition - Welsh slate and concrete tiles on Victorian terraces frequently reach end of life without obvious signs from street level
• Timber decay in roof structures and floor joists, especially where sub-floor ventilation has been blocked or reduced over the years
• Outdated wiring and plumbing installations that predate modern standards and require replacement
• Subsidence and differential settlement, particularly in properties close to former industrial land, culverted watercourses, or historical mine workings
• Inappropriate cement repointing of stone and brickwork that traps moisture and accelerates damage to the original masonry

Between the 1920s and 1940s, BB8 picked up a second layer of housing, with semi-detached houses and short terraces appearing on the edges of Colne and in nearby Foulridge, Trawden, and Kelbrook. Brick is the usual material here rather than stone, and cavity walls start to show up from the 1930s onwards. That brings a different set of concerns, such as failed cavity wall insulation and corroded lintels over doors and windows.

From the 1950s through to the 1980s, post-war council homes and private estates were added as well, especially on the outer edges of BB8. Asbestos-containing materials may still be present in textured ceilings, floor tiles, and pipe lagging, so these homes benefit from an EICR alongside the Level 2 Survey because of the age of the electrical installation.

East Lancashire has a long industrial story, and BB8 properties can carry environmental and structural risks that a buyer will not spot at viewing stage. Our surveyors are trained to look for those signs and set them out clearly in the report.

For over two centuries, coal extraction took place across the east Lancashire coalfield, and parts of BB8 sit within historical mining zones. Large-scale underground mining stopped decades ago, but shallow workings, drift mines, and bell pits from the nineteenth century can still cause localised subsidence, especially after prolonged rainfall when groundwater levels move. Our survey picks up cracking patterns consistent with mine settlement and recommends a Coal Authority search if one has not already been obtained. Your solicitor should be ordering that as part of the standard conveyancing searches for any BB8 property.

Flood risk matters for some BB8 buyers, and it should not be brushed aside. The River Colne and Pendle Water run through and around the town, and lower-lying streets near those watercourses can show medium or high flood risk on Environment Agency maps. Pendle Water at Barrowford has an active EA flood warning zone, reference 012FWFL27B, covering Gisburn Road, the college area and the streets beside them. Our surveyors look for visible signs of previous flooding inside properties, such as tide marks on internal walls, replaced floor finishes at low level, and damaged plaster at skirting height, and we include those observations in the report. We recommend that all BB8 buyers check the EA flood map for their exact address and confirm flood insurance is available with their broker before they exchange contracts.

Indicative repair costs our surveyors typically cite for BB8 properties:

• Chimney stack repointing and flashing replacement: £800 to £2,500 depending on height and access
• Full roof re-cover with slate or concrete tile on a standard terrace: £4,000 to £9,000
• Damp treatment, including injection DPC and replastering: £1,500 to £6,000 depending on extent
• Timber treatment and partial floor joist replacement: £2,000 to £8,000
• Full rewire of a Victorian two-up two-down terrace: £3,500 to £7,000
• Rising damp DPC injection and associated redecoration: £800 to £2,500

Some properties in and around Colne town centre fall within a designated conservation area, and a few are Grade II listed. The historic core of Colne includes Victorian commercial buildings and earlier domestic architecture, both of which come with planning restrictions on alterations. If you are buying a listed building or a property in a conservation area in BB8, our team recommends a RICS Level 3 Building Survey, because that level of detail is better suited to complex or historic structures.
