RICS Level 2 Survey in BA20

Yeovil has a long association with the aerospace industry. Honeywell UK operates in the town, specialising in Environmental Control Systems and Life Support Systems for aircraft. This sector drove significant residential development through the mid-20th century, as workers needed housing near the manufacturing sites. The resulting housing - typically semi-detached and terraced properties from the 1950s through to the 1980s - now forms a substantial proportion of BA20's residential stock.

Properties built in this era typically used cavity-wall construction with a standard brick outer leaf and blockwork inner leaf. When these properties have been well maintained and have not had insulation problems, they are generally straightforward to survey. Where deferred maintenance has allowed water ingress - through failed gutters, cracked render, or deteriorating window frames - moisture damage to the inner structure can accumulate over time without being visible on a casual inspection. A small number of Nissen-Petren steel-framed concrete cavity wall properties from the 1920s also exist within BA20 - a construction type co-invented in Yeovil itself. These require specialist mortgage lender approval and a Level 3 Building Survey is more appropriate for them than a Level 2.

Pre-war properties in Yeovil's town centre and older streets present different considerations. Solid brick walls pre-dating 1930 typically lack adequate roof and floor insulation by modern standards. Suspended timber ground floors in these properties are vulnerable to wet rot where sub-floor ventilation has been blocked - often by accumulated debris, vegetation growth against airbricks, or post-war floor screed laid over the original ventilated void. Our surveyors note the floor construction type and ventilation condition in every report.

Bungalows are a common property type in the outer areas of BA20. Single-storey properties with low-pitch roofs require particular attention to roof covering condition and to the junction between roof and wall at the eaves, where guttering problems can cause sustained water saturation to the external walls below. Flat-roof sections on extensions to bungalows are a known maintenance liability and are flagged consistently in our reports where found.

In Yeovil's older streets and in the villages within BA20, Ham Hill stone - known locally as Hamstone - is the characteristic building material of pre-Victorian and Victorian properties. Quarried at Ham Hill five miles to the west, this honey-coloured Jurassic limestone gives older Yeovil buildings their distinctive warm appearance, but it requires particular attention during a survey. The stone is porous and contains clay inclusion layers that weather at different rates, leading to surface erosion and mortar joint deterioration over time. The most consistent defects our surveyors find in Hamstone buildings are eroded lime mortar joints on north and west elevations exposed to prevailing rain, and - critically - inappropriate cement repointing applied by previous owners. Cement pointing on Hamstone looks solid but actively harms the stone: it is harder than the surrounding material, traps moisture within the wall rather than allowing it to escape through the joint, and causes accelerated decay to the face of the stone. Weathered arrises on cornices, quoins, and window surrounds are also a regular finding on older stone properties in central Yeovil. We describe mortar condition, repointing materials, and any stone face decay in our reports for pre-1900 properties.

Yeovil sits on Jurassic Lias Clay and limestone formations. These clay-rich soils are susceptible to seasonal shrink-swell movement - contracting in dry summers and expanding in wet winters. This differential ground movement can cause diagonal cracking above window openings and at the corners of older properties with shallow foundations. Our surveyors assess crack patterns, door and window alignment, and floor levels at every inspection to determine whether structural movement is historic and stable, or ongoing and active. Where we identify progressive cracking patterns, we recommend further investigation by a structural engineer and explain the basis for that recommendation clearly in the report.

Parts of the BA20 postcode area have elevated radon potential, arising from underlying Jurassic limestone and lias geology. Radon is a naturally occurring radioactive gas that accumulates in homes built on certain rock types, entering through floor joints and gaps in solid floors. The UK Health Security Agency publishes a radon potential map at ukradon.org where any address can be checked by postcode. Buyers purchasing older solid-floor properties in BA20 should consider commissioning a 90-day radon monitor after exchange. The action level is 200 Bq/m3; remediation measures such as positive pressure ventilation units typically cost £500-1,500. A RICS Level 2 survey does not carry out a radon test, but we note in our report when the property type and area suggest radon assessment is advisable. Active new build development continues within the wider Yeovil area. Persimmon Homes are building at Agusta Park, Kingfisher Drive, Houndstone (BA22 8GG), with 3 and 4-bedroom homes from £290,000. David Wilson Homes have properties available at Wyndham Park from £199,950. Stonewater's Swallowcliffe scheme at Senior Park School (BA20 1DH) added 31 affordable homes to the postcode. Buyers purchasing newly built properties should note that a snagging survey - not a Level 2 - is the appropriate product for a recently completed new build.

Every accessible element of the property is covered in our inspection. Roof structure and coverings, chimneys, walls, windows, doors, floors, ceilings, cellars, and drainage all receive a condition rating on the 1-2-3 scale. Condition 1 means no repair is currently required. Condition 2 means attention is needed in the short to medium term. Condition 3 means urgent repair or further investigation is needed before you exchange.

Damp assessment is carried out using a calibrated moisture meter applied systematically across all external walls and ground-floor areas. We distinguish between penetrating damp, rising damp, and condensation in the report - each has a different cause and a different cost to address. A damp report from a damp-proofing company is not an independent assessment, as these companies have a commercial interest in finding work. Our survey gives you an independent view before you commit.

Structural condition is assessed through crack patterns, door and window alignment, and floor levels. Where we find diagonal cracking, stair-step cracking in brickwork, or floors that are noticeably out of level, we describe the pattern in the report and indicate whether we consider it active or historic. Where we cannot determine the cause from a visual inspection alone, we recommend further investigation by a structural engineer - and we explain clearly why.

Services including the heating system, electrical consumer unit, and plumbing are noted as part of the survey. We do not carry out pressure tests or specialist electrical tests, but we flag apparent age and visible condition issues. Properties with older fuse boards, unsleeved wiring, or boilers showing significant age all receive specific commentary in the services section of the report.
