RICS Level 2 Survey in TN18

The TN18 postcode covers a striking stretch of rural Kent, with villages prized for their historic character and strong schooling. Our inspectors regularly survey homes across the area, from period cottages with exposed timber and weatherboard fronts to 1930s family houses and new build apartments. The stock is unusually mixed, ranging from early 19th Century Grade II Listed buildings to contemporary developments. Cranbrook School brings many families into the area, and the presence of excellent state and independent schools has a clear effect on the local housing market.

That mix brings its own complications. In Hawkhurst and Sandhurst, older houses often use traditional construction methods that sit well away from modern standards. We may find timber-framed structures, historic brickwork, or stone details that need an experienced eye. Properties near the Weavers House retirement development, or new builds on Bodiam Road in Cranbrook, have different questions around materials and newer construction. Many homes here also lie within conservation zones, so alterations over the years may have been done under rules that were not the same as those in force today.

For TN18 properties, our surveyors know what to look for. We check for damp penetration that is common in older cottages, assess roof coverings on homes that may be 100 years or older, and review electrical systems that might date from the mid-20th century. With 60 property sales in the last year and prices ranging from £185,000 for flats to over £640,000 for detached homes, professional survey cover is a sensible safeguard for such a major commitment. Most sales in TN18 sit in the £220,000 to £354,000 range, so these are not small purchases, and they deserve proper due diligence.

Local geology matters too. Kent's clay soils, especially in the Weald area that TN18 sits within, can shrink and swell as moisture levels change through the seasons. Our surveyors are trained to pick up the warning signs, including cracking patterns and doors that do not sit quite right, both of which can point to subsidence or foundation movement. It is not as extreme as in some other parts of the country, but it still deserves attention when buying period homes in this area.

• Thorough visual inspection of all accessible areas
• Condition ratings for key building elements
• Clear traffic light system highlighting defects
• Market valuation and insurance rebuild costs
• Advice on urgent repairs and maintenance

Surveying properties across Hawkhurst, Cranbrook and Sandhurst has shown us a few familiar themes. Many homes in the area date from the Victorian, Edwardian or early 19th Century periods, so they often lack modern insulation and can have electrical systems that are well out of date. We frequently come across wiring from the 1970s or earlier, which would not meet current Part P electrical safety requirements. It is especially common in houses that have not been modernised for some time.

In the historic core of TN18 villages, timber-framed houses with weatherboard exteriors can suffer from rot or insect damage that is not obvious without a close look. The exposed timber frames found in many period cottages need careful checking for woodworm activity, wet rot and dry rot. Solid brick properties may show penetrating damp, especially at ground floor level or where render has failed. Older TN18 houses built in solid wall construction do not have the cavity insulation that helps modern homes stay dry.

Older roofs raise another regular concern. Missing or slipped tiles, tired lead flashing and ageing felt underlays often come up in our inspections. Many of these roofs are original to the property, so tiles and underfelt may be decades beyond their expected life. We also see chimney defects quite often on period homes, including damaged flues, missing caps and crumbling brickwork that can let water in.

Because TN18 sits close to the Kent Weald, some properties rest on clay subsoils that expand and contract with seasonal moisture changes. The movement is not as marked as in some other places, but our surveyors still watch closely for signs of subsidence or movement that could affect foundations. Homes in lower-lying spots near watercourses may also need extra thought around drainage and exposure to moisture. We check floor levels and the outside ground levels against the property to judge damp risk.

• Damp and condensation in period properties
• Outdated electrical wiring (often 1970s or older)
• Roof deterioration on properties over 50 years old
• Timber decay in exposed beam structures
• Structural movement in properties on clay soils
• Missing or inadequate fire safety measures
