A Guide to Building Defects and How They Are Diagnosed

2 September 2025

At Simon Levy Associates, we understand that building defects can be a significant concern for property owners. Whether you're facing issues in a newly constructed home or an older property, identifying and addressing these problems promptly is crucial to maintaining the integrity and value of your investment. With over three decades of experience as chartered building surveyors in Borehamwood, we specialise in diagnosing a wide range of building defects and providing effective recommendations.

Common Building Defects We Diagnose

Our team is skilled in identifying a variety of building defects that can arise in both residential and commercial properties. Damp and water penetration can be frequent issues, often caused by leaks in roofing, faulty guttering, or inadequate damp-proof courses. This can lead to significant property damage if not addressed promptly. Condensation and mould growth are other common problems, typically resulting from poor ventilation and insulation, which create conditions for mould to thrive.

Structural movement is another serious concern, often seen as cracks in walls, ceilings, or foundations. This can indicate subsidence or heave, which may require urgent attention. Additionally, bulging or leaning walls can be signs of water damage or structural instability. Sound transmission issues between rooms or floors are also common, especially in properties with insufficient soundproofing.

Each of these defects can compromise the safety and comfort of your property, making early diagnosis and intervention essential.

Our Diagnostic Approach

When you engage Simon Levy Associates for a property inspection, we take a comprehensive approach to diagnose building defects. We begin with a detailed visual inspection, carefully examining both the internal and external elements of the building. This allows us to identify visible signs of defects, which may indicate underlying problems.

For structural defects, we conduct a thorough analysis of the building's structural components, including foundations, load-bearing walls, and roof structures. We evaluate the environmental factors surrounding the property, such as ventilation and drainage, that may be contributing to the defects.

Tailored Solutions and Property Advice

If necessary, we can refer you to trusted contractors from our network of reliable professionals, ensuring that the repair work is completed to the highest standards. Alongside this, we provide property maintenance advice, helping you take preventative measures to avoid future defects. Our goal is to not only resolve current issues but also equip you with the knowledge to maintain your property’s condition long-term.

Navigating Insurance Claims with Property Damage Experts

In cases where building defects result from incidents like flooding or fire, navigating insurance claims can be challenging. As property damage experts, we assist in documenting the damages, estimating repair costs, and ensuring that the insurance settlement reflects the full extent of the damage. We act as your advocate, working with your insurer to ensure that your claim is handled efficiently and fairly.
