RICS Level 2 Survey in BN44

The BN44 postcode covers Steyning, Bramber, Upper Beeding, Ashurst and the surrounding South Downs villages. Properties here span at least four distinct construction eras, and our surveyors have documented the defect patterns common to each one.

Pre-1919 properties - particularly the flint-fronted and brick-rendered houses on Steyning's High Street and Church Street - are solid-wall construction. Solid walls cannot be cavity-filled, so penetrating damp is a recurring finding. Our surveyors probe external elevations with moisture meters and inspect the internal face of external walls at low level to identify damp migration. On flint properties we check for failed pointing and loose flint panels, which can allow water ingress behind the face.

Edwardian and interwar properties (roughly 1900 to 1945) in the BN44 area frequently show issues with cast-iron guttering and downpipes that have been left unrepaired for years. Overflowing gutters saturate brickwork above the damp-proof course level, creating a damp stripe on internal walls that is easy to confuse with rising damp. Our surveyors always inspect gutters visually and check internal elevations directly below them.

Post-war properties built between 1945 and 1980 introduce cavity wall construction, but many of these cavities were later filled with mineral wool or beads that have deteriorated or bridged. In a wet climate adjacent to the South Downs, cavity fill can transfer moisture across to the inner leaf, causing damp on internal walls. We check the age and type of any cavity wall insulation and flag where further specialist assessment is needed.

• Flint and brick solid walls - check for penetrating damp and failed pointing
• Victorian and Edwardian slate roofs - inspect ridge tiles, valleys and lead flashings
• Cast-iron rainwater goods - check for blockages, leaks and corrosion
• Timber suspended floors - probe for rot and woodworm in pre-1945 stock
• Cavity wall insulation (post-1970) - assess condition and potential moisture bridging
• Flat roof extensions - identify blistering, splits and ponding water
• Older electrical installations - note consumer unit type and visible wiring condition

The South Downs National Park chalk bedrock that underlies most of BN44 is generally favourable for building foundations. Chalk is a relatively stable substrate and does not shrink and swell with moisture changes in the way that London Clay or Gault Clay do. This means shrinkage cracking from seasonal ground movement is less common in BN44 than in many parts of the South East.

However, chalk geology does present specific risks that our surveyors are trained to identify. Chalk dissolves slowly in acidic groundwater - a process called dissolution or piping - which can cause localised ground settlement under older properties. Properties built on chalk slopes or in areas with a history of chalk extraction (lime kilns were once common in the Sussex Weald) can be at elevated risk of ground movement from below.

Localised pockets of clay-with-flints overlie the chalk in parts of BN44, particularly on higher ground. Clay-with-flints soils do exhibit some shrink-swell behaviour, and large established trees adjacent to properties on these soils can draw moisture from the clay and cause subsidence. Our surveyors record tree proximity and species during the external inspection and assess any crack patterns in relation to ground conditions and drainage.

• Chalk bedrock - stable but can dissolve under long-term water ingress
• Clay-with-flints overlay on higher ground - some shrink-swell risk
• Tree proximity - mature oaks and willows near clay soils can cause subsidence
• Historic lime kiln sites - check for ground voids in older rural areas
• River Adur flood plain - soil saturation and ground heave risk in low-lying positions

Steyning is one of the best-preserved medieval market towns in West Sussex. The town centre contains a high concentration of listed buildings and sits within a designated conservation area - factors that affect how repairs and alterations can be carried out and what insurance cover is appropriate.

Grade II listed properties in Steyning require listed building consent for any material changes to the external or internal fabric - including replacing windows, repointing masonry in a different mortar, and certain internal structural changes. A RICS Level 2 Survey on a listed building will flag the listed status and note any visible alterations that may not have received the necessary consent. For listed buildings where significant works are anticipated, we recommend a Level 3 Building Survey to give you a fuller picture of the building fabric and maintenance liabilities.

Bramber Castle - the Norman motte-and-bailey castle managed by English Heritage - lies within the BN44 postcode. Properties in its immediate setting may be subject to additional planning constraints under the castle's scheduled monument designation. Our surveyors note the presence of nearby scheduled monuments or conservation designations where they are visible from the property, and recommend buyers seek confirmation of any planning limitations from the local planning authority before exchange.

At an average detached price of £640,638, buying in BN44 means committing a substantial sum to a property whose full condition is not visible from a viewing. The mortgage lender's valuation - which is sometimes bundled with the mortgage offer and often described as a 'survey' - is not a survey at all. It is a brief assessment for the lender's security purposes, typically taking 15 to 30 minutes, and it does not include a detailed condition inspection.

Our RICS Level 2 Survey is a separate, independent inspection carried out solely in your interests. The surveyor's duty of care runs to you as the buyer, not to the lender, the seller or the estate agent. This independence matters when defects are found - the report gives you an objective basis for renegotiation or for withdrawing from a purchase before you are legally committed.

In our experience, condition 3 defects found in BN44 surveys most frequently relate to roof repairs, damp remediation and drainage works. A failed lead valley gutter on a 1930s semi costs £800 to £2,500 to repair; full re-roofing on a detached property can reach £12,000 to £20,000. Having these figures before exchange gives you information that the asking price alone cannot provide.
