Whether you’re investing in a prestigious London property or a country estate in Berkshire, our home defect surveys will help you make informed decisions about your property.

What is a defect survey?
A defect survey, also known as a Structural Survey or Building Defect Report is a specific inspection that investigates possible and confirmed defects found in a property so that owners and potential buyers have all the information they need to make good decisions.
Unlike a full structural survey that examines the entire building, a defect survey focuses on particular issues that have caught your attention. From cracks in the walls to an uneven roof, you want to understand the full implications of these and the cost of putting them right. The answer is to commission a building defects survey report.
HOME DEFECT SURVEYS
Our residential defect surveys are particularly valuable for homeowners and potential buyers who need clarity on specific issues. These surveys can identify:
- Structural problems – Foundation issues, wall cracks, or beam concerns
- Moisture issues – Damp patches, condensation problems, or potential water ingress
- Electrical concerns – Outdated wiring, faulty installations, or safety hazards
- New build defects – Snagging issues, poor workmanship, or incomplete installations that developers should address
New builds aren’t immune to problems. In fact, building defect surveys for new properties can uncover issues that should be rectified under warranty or by the developer. Common new build defects include poor plastering, inadequate insulation, drainage problems, or sub-standard finishes that don’t meet building regulations.
If you are living in a property and have concerns about a defect, or you are worried about something that you’ve spotted in a property you wish to buy, our detailed building defects survey reports will allow you to get detailed information about the extent of the issue and we can even provide a quote to rectify them.
Structural Integrity
We thoroughly inspect the building’s main structure to ensure its stability and safety. Our survey looks for any underlying faults that could lead to long-term issues, giving you peace of mind about the building’s overall condition.
Detailed Reporting
Our surveys provide detailed reports, complete with clear images, comprehensive findings, and actionable recommendations. This allows you to make informed decisions based on the condition of your property and any necessary repairs.
DEFECT SURVEYS FOR COMMERCIAL PROPERTIES
Commercial properties face unique challenges, making defect surveys essential for business owners and investors. Commercial building defect surveys can identify:
- Fire safety compliance issues
- Accessibility problems
- HVAC system failures
- Structural integrity concerns that could affect business operations
Dilapidation surveys form a crucial part of commercial property management for both landlords or tenants when commencing or ending a lease. Typically most leases will require the tenant to pay for the dilapidations at the end of a lease so a building defects survey report provides a detailed assessment giving you a clear itemised list of issues that need to be addressed and the approximate costs to put the property back in a good state of repair.

When to get a defect survey
The best time for a building defect survey depends on your specific situation:
For buyers: Before completing your purchase, especially if you’ve noticed something concerning during viewings. This gives you leverage to negotiate repairs or adjust the price.
For homeowners: When you first notice a problem, before it potentially worsens. Early intervention often means less expensive repairs.
For new builds: During your snagging period or just before warranty expires. Developers are typically responsible for fixing defects during this time.
For commercial properties: Towards the end of your lease to understand the full extend of what needs to addressed to hand the property back to the Landlord in good condition.
How long does a defect survey take?
Most defect surveys take between 2-4 hours, depending on the complexity and size of the area being inspected. You’ll typically receive your report within 7 working days.
How much does a building defect survey cost?
Costs vary depending on the property size and complexity of the issue. Generally, defect surveys are more affordable than full structural surveys as they focus on specific problems rather than the entire property.
What's the difference between a defect survey and a dilapidation survey?
While both are building inspections, a defect survey typically identifies specific problems in a property you own or are buying. A dilapidation survey, often required for commercial properties, assesses the overall condition for lease purposes or to establish responsibilities between landlords and tenants.
Will the survey tell me how much repairs will cost?
While surveyors can provide rough estimates and prioritise repairs, you’ll typically need quotes from relevant tradespeople for accurate costings. However, the survey will give you enough information to negotiate or budget effectively.
