New-build defect inspections by RICS-registered surveyors. From £300 for a 1-bedroom flat.
Buying a new-build property in the London Borough of Barnet is an exciting milestone, but even the most reputable developers can leave behind defects that only become apparent after you move in. A snagging survey provides you with a detailed inspection of your new property, identifying cosmetic issues, faulty installations, and structural concerns before they become costly problems. Our RICS-registered team works exclusively for you, the homeowner, providing an independent assessment that developers cannot influence.
Barnet's property market has seen significant new-build activity in recent years, with developments popping up across Mill Hill, Hendon, Colindale, and Chipping Barnet. From apartments in modern conversions to family homes in large-scale estates, our local surveyors understand the common defect patterns found in these developments. With the average new-build price in Barnet hovering around £465,000, a snagging survey represents a small investment that can save you thousands in unexpected repair costs.
We conduct thorough, room-by-room inspections lasting 2-4 hours depending on property size, examining over 300 individual points throughout your new home. Our reports include detailed photographs of every defect, severity ratings, and clear recommendations for remediation. This documentation becomes your evidence base when negotiating with the developer or warranty provider during the critical defects liability period.

The London Borough of Barnet has become a hotspot for new residential development, with major housebuilders including Barratt London, Redrow, Fairview New Homes, and Catalyst (The Hill Group) delivering hundreds of new homes each year. Developments such as The Mount in Mill Hill, Colindale Gardens, Hendon Waterside, and Brook Valley Gardens have transformed the borough's landscape. While these properties come with the allure of being brand new, they are not immune to construction defects, and our experience inspecting hundreds of these homes has shown us exactly what to look for.
Our inspectors typically identify between 100 and 200 snagging items in a typical new-build home in this area. The most frequently encountered issues include poorly finished plasterwork with uneven surfaces and visible joints, doors and windows that do not close properly or have damaged seals, incomplete sealant around wet areas leading to potential water ingress, and drainage issues that manifest as slow drains or improper fall on waste pipes. These may seem minor, but left unchecked, they can develop into significant problems that the developer may later refuse to address once the defects period expires.
More serious structural and engineering items our Barnet surveyors encounter include hairline cracks in walls that may indicate movement or inadequate drying of materials, incorrectly installed lintels above openings, damp proof course (DPC) issues particularly problematic given Barnet's London Clay geology, and roof tile alignment problems that can lead to leaks. The presence of London Clay beneath much of Barnet means that ground movement is a genuine concern, making proper construction even more critical. Our surveyors pay particular attention to foundations and substructure in properties near the Silk Stream and Dollis Brook, where surface water flooding can compound moisture-related issues.
The predominantly brick construction of Barnet's newer developments is generally sound, but we often find issues with cavity wall insulation installation, particularly in apartment blocks where cavity barriers may be missing or incorrectly positioned. This is a fire safety concern that we take seriously, documenting any gaps or voids in our reports. Render finishes on newer properties also require careful inspection for cracks and delamination, issues we encounter regularly on Barnet's modern housing estates, particularly on south-facing elevations exposed to weathering.

We conduct a comprehensive inspection of all accessible areas of your new-build property, examining over 300 individual points. Our survey covers the entire envelope of the building, from the roof space down to the foundations, and every room in between. We check the quality of workmanship throughout, comparing the finished property against the specification agreed in your purchase contract and building regulations standards.
Our detailed report photographs every defect we find, categorising issues by severity from urgent structural concerns that require immediate attention to minor cosmetic snags that the developer should rectify before the defects period expires. We provide clear recommendations for each item, explaining what needs to be fixed, who is responsible, and the expected timeline for resolution. This report becomes your evidence base when negotiating with the developer or warranty provider, giving you the professional documentation needed to pursue claims effectively.
The inspection covers all key building systems including windows and doors, kitchen appliances and fixtures, bathroom fittings, plumbing connections and water pressure, electrical installations and safety, heating system operation and commissioning, ventilation adequacy, and external areas including gardens, balconies, and parking spaces. For properties at Colindale Gardens and Hendon Waterside where balcony access is a major feature, we pay particular attention to waterproofing details and balustrade safety.
Choose your property type and preferred date. We offer flexible appointments including evenings and weekends to suit your moving schedule. Our online booking system shows real-time availability for properties across Mill Hill, Hendon, Colindale, Chipping Barnet, and all Barnet postcodes.
Our RICS-registered surveyor visits your Barnet property and conducts a thorough, room-by-room inspection lasting 2-4 hours depending on size. For larger detached homes in developments like The Mount in Mill Hill, the inspection may extend beyond four hours to ensure every detail is documented. We check all accessible areas including roof spaces, under-floor voids, and communal areas where applicable.
Within 24-48 hours, you receive our comprehensive snagging report with photos, severity ratings, and clear recommendations for each defect. The report follows RICS standards and includes a summary for easy reference when discussing issues with the developer. Each defect is cross-referenced to relevant building regulations and your purchase contract specifications.
Use your report to negotiate with the developer. We can provide additional support letters if needed for warranty claims or dispute resolution. Our team can also advise on NHBC or similar warranty claim procedures if the developer fails to respond adequately to our findings.
Book your snagging survey as soon as possible after legal completion but before the developer defects period expires. Most new-build homes come with a two-year developer warranty and a 10-year NHBC or equivalent structural warranty. Report defects promptly to ensure you do not lose your right to have issues resolved. The first few weeks after completion are crucial for identifying problems while the developer remains responsive.
Our team has inspected properties across all the major new-build sites in the London Borough of Barnet, giving us detailed knowledge of development-specific defect patterns. At The Mount in Mill Hill (NW7 1QS), Barratt London offers a mix of apartments and houses where we frequently find issues with window installations and exterior cladding. The development sits on former golf course land, and we've noted drainage patterns that require careful assessment during heavy rainfall.
High Street Quarter in Barnet town centre (EN5 5XQ) has seen hundreds of apartments change hands, with common snags including balcony door seals and communal area finishes. This development's proximity to Barnet High Street means our surveyors also check sound insulation between apartments, a particular concern for urban new builds where noise transfer can affect quality of life. The underground parking areas require attention to waterproofing and ventilation systems.
Brook Valley Gardens in Chipping Barnet (EN5 2FL) from Catalyst has been a particularly active development, and our inspectors have identified recurring issues with ground floor damp proofing and apartment entrance door alignment. Given the local clay soil conditions, we pay close attention to how foundations have been constructed and whether proper drainage is in place. The development sits near green belt land, and we've seen issues with wildlife ingress in ground floor properties.
Colindale Gardens (NW9 5BX) by Redrow is another large-scale development where we see typical new-build defects, particularly in the apartment blocks where fire door installations and balcony waterproofing require careful checking. The proximity to the Silk Stream means we assess flood resistance measures at lower ground floor levels. Hendon Waterside (NW9 7DE) from Barratt London and The Artisan in Mill Hill (NW7 1QY) from Fairview New Homes represent newer phases where our reports have highlighted issues with heating system commissioning and ventilation adequacy.
Understanding these development-specific patterns helps our surveyors focus their inspection on the areas most likely to contain defects, saving time while ensuring nothing is missed. We maintain records of defect patterns at each major development, allowing our surveyors to arrive at your property with specific knowledge of what to scrutinise most carefully. This local expertise adds significant value beyond the standard survey checklist.
Given Barnet's geology, which features extensive London Clay deposits, our surveyors pay particular attention to signs of subsidence or heave. While most new-build properties have deeper foundations designed to bypass the problematic clay layer, we still check for cracking patterns, door operation changes, and window binding that could indicate ground movement. Properties near the Silk Stream and Dollis Brook require additional attention to lower ground floor levels and basement waterproofing, where we frequently identify issues with tanking systems and drainage.
The predominantly brick construction of Barnet's newer developments is generally sound, but we often find issues with cavity wall insulation installation, particularly in apartment blocks where cavity barriers may be missing or incorrectly positioned. This is a fire safety concern that we take seriously, documenting any gaps or voids in our reports. Render finishes on newer properties also require careful inspection for cracks and delamination, issues we encounter regularly on Barnet's modern housing estates, particularly after winter freeze-thaw cycles when moisture trapped behind render can cause significant damage.
Our Barnet surveyors have identified recurring problems with development drainage systems, particularly in larger sites where surface water management relies on underground attenuation systems. We check that gulleys are clear, fall directions are correct, and that drainage from balconies and roof areas is properly directed away from the building envelope. In our experience, drainage is one of the most commonly overlooked areas by developers, yet it causes some of the most serious long-term damage when it fails.
Electrical safety remains a key focus, and we test a representative sample of sockets and lighting circuits in every property. Recent new builds have seen issues with inadequate earthing, incorrect circuit breaker sizing, and poor-quality consumer units. For developments with communal heating systems like those at Colindale Gardens, we also check that individual flat heating controls are properly commissioned and that residents have been provided with adequate user instructions.
A snagging survey examines every accessible part of your new-build property for defects, including walls, ceilings, floors, windows, doors, kitchens, bathrooms, plumbing, electrical installations, and external areas. We check that work has been carried out to proper standards and building regulations. Our report typically identifies between 80 and 200 individual defects, depending on property size and construction quality. For apartments in developments like High Street Quarter or Colindale Gardens, we also inspect communal corridors, entrance halls, and shared facilities that form part of your property purchase.
Prices in Barnet start from £300 for a small 1-bedroom flat and range up to £850 or more for large 5-bedroom detached houses at developments like The Mount in Mill Hill. The cost reflects the size of the property and the time required for inspection, typically 2-4 hours on site. Given the average new-build price in Barnet of around £465,000, a snagging survey represents a tiny fraction of your investment but can save you thousands in defect remediation. The cost of fixing just one major issue such as damp proofing failure or structural movement far exceeds the survey fee.
Book your survey as soon as you have a confirmed completion date or key collection date. Ideally, inspect the property before you move in furniture and belongings, as this allows our surveyor full access to all areas including behind furniture and in cupboards. Most developers allow a defects inspection period within the first weeks of ownership, so timing is important. If you've already moved in, don't worry - we can still inspect, but you'll need to clear access to built-in furniture and appliances where defects may be hiding.
While developers sometimes wish to attend, we conduct our inspection independently for you, the homeowner. Our surveyor works solely in your interest, documenting defects accurately without pressure to downgrade findings. You are entitled to have an independent survey, and developer attendance is not required for us to carry out a thorough inspection. In our experience, developer presence can sometimes limit what our surveyor can access or comment on freely. We recommend that you attend the survey yourself so you can see defects firsthand and ask questions about remediation.
If our report reveals serious issues such as structural concerns, significant damp problems, or electrical safety hazards, we will flag these as urgent priority items requiring immediate attention. We provide clear recommendations for each defect, explaining who is responsible for rectifying it under your warranty cover. Most developers will attend to significant defects within their defects liability period, and your report gives you the evidence needed to chase resolution. For issues falling under NHBC cover, we can advise on the claim process and what documentation you'll need.
Yes, absolutely. While NHBC and other structural warranty providers cover major structural issues, they do not cover cosmetic defects or minor finishing problems. These are the developer's responsibility during their typically two-year defects liability period. A snagging survey ensures you document all issues while they are the developer's responsibility, rather than discovering them months later when you must cover the cost yourself. Our report provides the professional documentation needed to make a valid claim within the warranty period, protecting your investment long-term.
Given Barnet's extensive London Clay deposits, our surveyors pay special attention to signs of ground movement including cracking patterns in walls, doors that stick or bind, and windows that don't close properly. We also check drainage from the property, as clay soil has poor drainage characteristics that can lead to surface water flooding. Properties near the Silk Stream or Dollis Brook require particular attention to lower ground floor levels and any basement or underground parking waterproofing. Our report will flag any concerns specific to the local geology that could affect your property long-term.
We deliver your comprehensive snagging report within 24-48 hours of the inspection, typically by the next working day. The report includes high-resolution photographs of every defect, severity ratings using our traffic light system, and clear remediation recommendations. You'll receive a digital PDF version via email, with a printed version available on request. For urgent cases where you've discovered serious defects, we can prioritise report turnaround to help you meet developer deadlines.
