New Build Defect Inspections - Protect Your Investment








Purchasing a new build property in SE3 represents a significant investment, with average house prices in Blackheath, Kidbrooke, and Westcombe Park reaching over £650,000 according to recent market data. While new homes come with warranties, these protections are only as effective as your knowledge of existing defects. Our snagging survey provides a comprehensive inspection of your new build, identifying cosmetic and structural issues before they become expensive problems.
SE3 has seen substantial new build activity, particularly in the Blackheath area where 110 new properties were sold between February 2025 and January 2026. Our qualified inspectors bring extensive experience examining properties across this postcode, understanding the common issues that arise with modern construction methods used in the region. From freshly painted walls to fundamental structural elements, we document every defect so you can request corrections from your developer.
Flats dominate the SE3 property market, accounting for 67.4% of all sales in the area, which means many buyers are purchasing apartments in modern developments. These properties often come with shared ownership arrangements or Help to Buy schemes, and our surveys ensure you receive exactly what you paid for. We have inspected properties across all the major new build developments in SE3, from conversion projects to purpose-built apartment blocks.

Our comprehensive snagging inspections cover over 500 individual checklist items, examining every accessible area of your new build property. We begin with the structural elements, checking for cracks in walls that may indicate settlement issues, examining lintels for proper installation, and verifying that damp proof courses are correctly positioned. Our inspectors understand that even seemingly minor defects can escalate into major repair costs if left undocumented.
The internal inspection focuses on finishing quality that developers often overlook. We test every electrical socket, check that doors open and close properly, examine plasterwork for cracks and uneven surfaces, and verify that all sealant around bathrooms and kitchens is complete. Windows and doors are checked for proper sealing, operation, and security features. Our inspectors frequently find issues with poorly fitted kitchen units, incomplete grouting, and paintwork that does not meet acceptable standards.
External elements receive equal attention during our SE3 surveys. We inspect roofing materials for damage and proper installation, examine gutter systems for blockages and proper fall, check boundary treatments and landscaping against specification, and assess driveways and pathways for completion. Many new builds in the SE3 area feature modern construction methods, and our inspectors are trained to identify issues specific to contemporary building techniques while also recognising traditional defects that may affect older new builds.
We pay particular attention to the communal areas in flat developments, as these often show signs of rushed completion. This includes checking shared hallways, stairwells, entrance lobbies, and any external areas that form part of your leasehold interest. Our inspectors document any defects in these common areas because they can affect your property's value and your quality of life in the development.
Our inspectors approach every SE3 property with meticulous attention to detail, understanding that your new home represents one of the largest purchases you will ever make. We photograph every defect we discover, providing visual evidence that supports your remediation requests to the developer. The comprehensive report includes specific locations, severity classifications, and recommended remediation approaches for each item.
The report serves as an official document that you can present to your developer or housing association, creating a formal record of all identified issues. This documentation proves invaluable when negotiating repairs or, in serious cases, when engaging with warranty providers such as NHBC. Our reports follow industry standards and are accepted by all major warranty providers operating in the UK new build market.
We understand that buying in SE3 means dealing with some of the highest property prices in London, so we take our role in protecting your investment seriously. Whether you've purchased a flat in a Blackheath conversion or a house in a new Kidbrooke development, our inspectors treat every property with the same thoroughness. We know that even small defects can be frustrating when you've paid a premium for a brand-new home.

The SE3 property market has seen prices dip 3% over the past year and 7% from the 2022 peak of £700,872, making it more important than ever to ensure your new build is in perfect condition. When you're investing hundreds of thousands of pounds in a property, a snagging survey provides the assurance that you're getting what you paid for. Many buyers assume that newbuild means flawless, but our experience shows that even properties built by reputable developers can have dozens of defects.
Recent price trends in SE3 show that while Blackheath (SE3 0) saw 2.2% growth and Kidbrooke (SE3 8) saw 3.5% growth, the overall market remains competitive. Buyers in this area are often competing for limited new build stock, which means they may feel pressured to complete purchases quickly without proper due diligence. Our snagging survey gives you the information you need to proceed with confidence or negotiate corrections before you've moved in.
The high proportion of flats in SE3 means many buyers are purchasing leasehold properties with specific rights and obligations. Our surveys include checking that the property matches the specification in your contract, that all fixtures and fittings are present and functional, and that any shared facilities meet expected standards. This level of detail is essential for protecting your investment in the leasehold system.
Schedule your snagging survey at a convenient time. We offer flexible appointments across SE3, including weekend availability. Provide us with your development details and any specific concerns you've noticed in your new property.
Our qualified inspector visits your SE3 property and conducts a thorough examination of all accessible areas. The inspection typically takes 2-4 hours depending on property size. We photograph and document every defect discovered during the survey.
Within 48 hours of the inspection, you receive a comprehensive snagging report via email. The report includes a summary of all defects, photographic evidence, severity classifications, and recommended next steps for remediation.
If needed, our team can provide guidance on presenting your report to the developer or housing association. We can advise on the best approach for getting issues resolved, whether through direct negotiation or warranty claims.
Book your snagging survey as soon as possible after receiving your keys. Most developer warranties have specific timeframes for reporting defects, and delays can result in losing your right to free remediation. Many issues become apparent only after you begin living in the property, so schedule your survey within the first few weeks of occupancy.
Our inspectors consistently identify recurring patterns of defects across new build properties in the SE3 area. Poorly finished plasterwork ranks among the most common issues, with walls showing cracks, uneven surfaces, and incomplete coverage around edges and corners. These cosmetic defects may seem minor but often indicate rushed finishing work that suggests other, more serious issues may exist.
Door and window deficiencies frequently appear in our SE3 surveys. Ill-fitting doors that stick or drag, windows that do not seal properly, and handles or locks that operate roughly all reduce your quality of life and can affect security. These issues often result from rushed installation schedules and inadequate checking before homeowner handover.
Incomplete or defective sealant represents another major category of findings. Gaps around bathtubs, showers, windows, and door frames allow moisture penetration that leads to damp problems and mould growth. Our inspectors systematically check all wet areas and external openings, documenting any gaps or deterioration that compromise the weatherproofing of your property.
Drainage issues frequently emerge in new builds, with our SE3 inspectors finding blocked or poorly connected gutters, inadequate fall on external paving, and missing or damaged drainage grilles. These problems may seem minor initially but can cause significant water damage to foundations and external walls if not addressed promptly.
In flat developments, we often find issues with sound insulation between units, which can significantly affect your enjoyment of the property. Poorly installed internal doors, inadequate fire sealing around service penetrations, and incomplete compartmentalisation are all defects we document regularly in SE3 new builds. These issues are particularly important given the high proportion of flats in the area.
A snagging survey examines every accessible element of your new build property for defects or incomplete work. This includes structural elements, plasterwork, joinery, electrical fixtures, plumbing, windows, doors, damp proofing, insulation, and external areas. Our inspectors use a comprehensive checklist covering over 500 individual items to ensure nothing is overlooked. We also check communal areas in flat developments and verify that all fixtures and fittings match your contractual specifications. The survey is visual and non-invasive, meaning we examine what we can see without disturbing any finished surfaces.
You should book your snagging survey as soon as possible after receiving your keys from the developer. Most warranties require defects to be reported within specific timeframes, often the first few months of occupancy. Even if you notice minor issues during your initial walkthrough, a professional survey will identify problems you might miss and establish the documentation needed for remediation requests. Given the competitive nature of the SE3 market where properties change hands quickly, don't delay in scheduling your survey. The earlier we inspect, the more time you'll have to negotiate corrections with the developer before any warranty periods expire.
The duration depends on your property size and condition. A typical two-bedroom flat may take 2 hours, while larger houses can require 3-4 hours for a thorough inspection. Our inspectors work systematically through the entire property, so larger properties naturally require more time to examine comprehensively. In SE3, where flats make up 67.4% of sales, most surveys complete within 2-3 hours. We never rush our inspections - our goal is to identify every single defect so you have complete documentation for your developer.
Your report includes a detailed list of all identified defects with photographic evidence and severity ratings. You can present this report directly to your developer or housing association to request remediation. For warranty claims, the documentation supports your case with NHBC or other providers. If the developer refuses to address issues, the report provides evidence for any dispute resolution processes. Our team can provide guidance on the best approach for your specific situation, whether that involves direct negotiation with the developer or escalating through warranty channels.
Pricing varies based on property size and type. Our snagging surveys in SE3 start from £450 for smaller properties, with larger homes requiring higher investment for the more comprehensive inspection required. Given that the average property price in SE3 exceeds £650,000, the cost of a snagging survey represents excellent value for money. The potential savings from having the developer address defects that would otherwise require private remediation can run into thousands of pounds. Many buyers find that their survey pays for itself multiple times over when major issues are identified and resolved at the developer's expense.
Yes, we regularly inspect shared ownership and Help to Buy properties across SE3. These properties still qualify for snagging surveys, and the documentation is equally important for protecting your investment. The process remains identical, and our reports are accepted by all housing associations and warranty providers. Given the high proportion of flats in SE3, many buyers use government schemes to get onto the property ladder here, and we understand the additional importance of documenting defects when you have a shared ownership stake. Our reports help you understand exactly what you're getting for your share of the property and what the housing association is responsible for maintaining.
Our inspectors are experienced professionals who provide objective, well-documented reports that withstand scrutiny. When developers dispute our findings, the photographic evidence and detailed descriptions we provide typically support the homeowner's position. If a dispute cannot be resolved directly, the documentation from our survey serves as valuable evidence for any warranty claim or dispute resolution process. We have experience dealing with all major warranty providers including NHBC, and our reports are structured to meet their requirements for claim submissions. Many developers prefer to address issues rather than risk formal disputes that could affect their reputation.
Yes, our snagging surveys include a thorough external inspection covering all accessible exterior elements. This includes checking the roof, gutters, downpipes, external walls, windows, doors, balconies, and any garden or ground floor areas. In SE3, where many properties are flats, we also examine communal external areas that form part of your leasehold interest. We check for proper installation of cladding, adequate drainage fall away from buildings, and any visible defects in brickwork or rendering. External defects can lead to serious problems like damp penetration, so we document everything we find.
