What Defects Do Level 3 Surveys Find?

📘 What Defects Do Level 3 Surveys Find?

When you’re thinking about buying a property — especially something older, unusual, or with a bit of character — a Level 3 survey (formerly called a Building Survey) is the most comprehensive way to understand exactly what you’re getting. It goes well beyond a basic HomeBuyer Report and drills right into what might be lurking behind the walls.

Here’s what a Level 3 survey can uncover:

🔎 Structural Issues
A Level 3 survey takes a detailed look at the heart of the property’s structure, including foundations, walls, floors, roof and chimneys, to spot things like cracks, movement, rot or subsidence that could affect long-term stability.

💧 Damp, Rot & Timber Problems
Surveyors check for rising or penetrating damp, woodworm, dry rot and other moisture-related defects that may not be visible without careful inspection.

🏚 Roof & Envelope Defects
Loose tiles, failing flashings, deteriorated joinery, or poorly performing roofs are investigated in detail, including roof spaces where it is safe to gain access.

🪟 Internal Defects
Inside the property, surveyors examine ceilings, floors and walls, identifying uneven floors, cracking, signs of structural stress, and areas where historic repairs may be failing.

⚡ Services Condition
While specialist testing isn’t done, Level 3 reports note the visible condition of electrics, plumbing, heating, drainage and more, flagging concerns and recommending further specialist checks if needed.

🌳 Site & Grounds Issues
Surveyors also consider the property’s surroundings, drainage, boundary walls, garages/outbuildings, and nearby trees that could impact foundations or cause damp problems.

🧱 Hidden or Potential Problems
Unlike simpler surveys, Level 3 reports interpret what defects mean for the future, from repair urgency and costs to predicted maintenance needs, helping you budget and negotiate effectively.

In short, a Level 3 survey doesn’t just list visible defects, it explains their cause, consequence and recommends obtaining costs to fix. That’s invaluable insight when you’re investing hundreds of thousands of pounds in a home.
