Older properties in Chichester portray unique charm and character that modern builds often lack. Yet beneath the period features and attractive facades, structural problems can hide for years before showing visible signs. Understanding what can go wrong helps buyers make informed decisions rather than discovering expensive issues after exchange of documents.
When purchasing an older property, engaging a Surveyor Chichester provides essential insight into the building’s condition. Professional surveyors use specialised techniques to detect problems that untrained eyes miss completely. From foundation movement to hidden timber decay, these experts identify issues early when remedial work costs less and causes minimal disruption to your plans.
Subsidence and Foundation Movement
Recognising the Warning Signs: Cracks in walls don’t always mean subsidence, but diagonal cracks wider than a five pence piece deserve professional attention. Older Chichester properties often show seasonal movement due to clay soils that expand when wet and shrink during dry periods. Surveyors measure crack widths and assess patterns to determine if movement remains active or historical.
Investigation Methods Used: Experienced surveyors examine external ground levels, check for nearby vegetation, and assess drainage systems that might be contributing to soil instability. They look at internal walls, ceilings, and door frames for distortion patterns. Sometimes they recommend monitoring over several months to establish whether cracks continue growing or remain stable.
Understanding the Implications: Foundation repairs can range from minor underpinning to extensive structural work costing tens of thousands. Getting accurate diagnosis early lets you negotiate purchase prices or budget properly for repairs. Some movement stabilises naturally once trees are managed or drainage improved, saving substantial expense.
Timber Decay and Insect Infestation
Common Types of Damage: Older properties with solid timber floors, roof structures, and wall plates face risks from wet rot, dry rot, and woodworm. Wet rot occurs where timber stays damp, causing wood to soften and crumble. Dry rot spreads more aggressively, sending fungal threads through masonry to attack dry timber elsewhere. Woodworm creates networks of small holes and tunnels that weaken structural members over time.
Detection Techniques Applied: Surveyors probe timber with specialised tools to test for softness indicating decay. They examine roof spaces, floor voids, and areas around plumbing where moisture accumulates. Fresh woodworm flight holes show active infestation, whilst old holes with no dust suggest past problems already treated.
Dampness and Moisture Ingress
Multiple Sources of Water Entry: Rising damp, penetrating damp, and condensation each require different solutions. Rising damp affects ground floor walls where damp proof courses have failed or been bridged by external ground levels. Penetrating damp comes through defective roofs, failed pointing, or cracked render. Condensation appears where poor ventilation meets cold surfaces, particularly in bathrooms and kitchens.
Professional Assessment Methods: Moisture meters provide initial readings, but experienced surveyors interpret results carefully since meters can give false positives from salts in old plaster. They check ventilation, inspect roof coverings, examine external walls for defects, and assess whether visible staining patterns match claimed causes. Thermal imaging cameras sometimes reveal cold spots indicating hidden moisture or missing insulation.
Cost and Priority Considerations: Damp issues vary enormously in severity and repair costs. Failed guttering might cost hundreds to fix, whilst comprehensive damp proofing and replastering runs into thousands. Surveyors help you understand which problems need immediate attention and which can wait, letting you plan expenditure sensibly.
Defective Cavity Wall Ties
The Hidden Structural Risk: Properties built between 1920 and 1980 typically have cavity walls with metal ties connecting inner and outer leaves. These ties corrode over time, causing walls to bulge outward and horizontal cracks to appear in mortar joints. The problem develops slowly, so owners often fail to notice until significant movement occurs.
Inspection Approaches: Surveyors look for bulging brickwork, horizontal cracks at regular intervals, and rust staining on external walls. Specialist equipment can detect corroded ties without destructive investigation. In some cases, removing a few bricks provides direct visual confirmation of tie condition.
Repair Planning: Replacing cavity wall ties involves drilling through both wall leaves to install stainless steel replacements. Costs depend on property size and access difficulties. Getting this work done prevents walls separating and maintains structural integrity for decades ahead.

Roof Structure Deterioration
Common Problems Found: Original roof timbers in older Chichester properties face threats from:
- Timber decay where ventilation proves inadequate or flashing has failed.
- Beetle infestation weakened structural members over many years.
- Previous alterations that removed supports or added excessive loading.
- Spread or sagging where wall plates have moved or timber connections failed.
Survey Investigation Process: Accessing roof spaces lets surveyors examine rafter condition, check for deflection in purlins and ridge beams, and assess ventilation adequacy. They look for signs of past or current leaks, test timber for soundness, and evaluate whether the structure still performs as designed.
Long-term Considerations: Roof repairs range from replacing individual timbers to complete re-roofing with structural upgrades. Understanding the roof’s condition before purchase helps you budget properly and avoid nasty surprises. Some issues need addressing urgently to prevent water damage spreading, whilst others can be planned for future work.
Conclusion
Older properties in Chichester offer wonderful living spaces when structural issues get identified and addressed properly. Professional building surveys reveal problems before they become emergencies, giving you knowledge to negotiate fairly and plan repairs sensibly. Whether you’re buying a period cottage or Victorian terrace, investing in expert inspection protects your interests and helps you make confident property decisions based on facts rather than assumptions.
