The new-build market in Isleworth TW7 has grown significantly in recent years, with developments like Rothbury Row bringing modern townhouses to the area. However, even the most reputable developers can overlook defects during the construction process, and these issues may not become apparent until months after you have moved in. Our snagging survey identifies problems while they are still the developer's responsibility, saving you potentially thousands of pounds in repair costs.
The TW7 area presents unique considerations for new-build properties. Being situated along the River Thames means that flood resistance measures are particularly important, and our inspectors verify that all specified protections have been correctly installed. We check external door seals, damp proof membranes, and any basement waterproofing systems to ensure your property is adequately protected against water ingress. These area-specific checks go beyond a standard inspection and reflect our understanding of local conditions.
Additionally, many properties in Isleworth are built on what was previously industrial land, undergoing significant regeneration in recent decades. Our inspectors are aware of the potential challenges this can present, including ground stability and the condition of any retained foundations or structures from previous buildings. We document everything we find, giving you a complete picture of your property's condition.
The excellent schools in the TW7 area, many rated Outstanding by Ofsted, make Isleworth particularly popular with families. When you are investing in a home specifically to be close to these schools, you need to know that your property is in perfect condition. Our snagging survey ensures that nothing detracts from your plans for your new home, from the boiler heating your radiators to the locks securing your windows.
Our snagging survey in TW7 covers over 500 individual check points throughout your property, examining everything from the roof down to the foundations. We inspect the quality of plasterwork, paint finishes, flooring, doors, and windows, ensuring everything operates as it should and meets the expected standard. Our inspectors also check the installation of kitchen units, bathroom fixtures, and built-in appliances, documenting any gaps, scratches, or improper fittings that detract from your new home.
Beyond cosmetic issues, we examine the structural elements of your property including load-bearing walls, lintels, and the condition of the damp proof course. Our team checks that cavity trays have been correctly installed, that roof tiles are properly aligned, and that all drainage systems function correctly. In our experience, we typically find between 100 and 200 snags in a typical new-build property, ranging from minor cosmetic defects to more serious issues that could cost thousands to put right later.
We pay particular attention to the mechanical and electrical installations in your new-build property. This includes testing socket outlets, checking that light switches function correctly, verifying that the boiler operates safely and efficiently, and ensuring that radiator valves are properly installed and balanced. Our inspectors also check the hot and cold water pressure throughout the property, documenting any issues with flow rates or temperature consistency that could indicate problems with the plumbing installation.
Given that Isleworth sits alongside the River Thames, our inspectors also pay particular attention to any flood resistance measures specified in your property's construction. We verify that all external doors have appropriate seals, that ground level damp proof membranes are correctly installed, and that any basement or below-ground areas have adequate waterproofing. These area-specific considerations ensure your survey is tailored to the local environment.
Whether you have purchased a flat at one of the modern developments in Isleworth, a terraced house, or a detached property, our inspectors approach every survey with the same meticulous attention to detail. We understand that buying a new-build is meant to be an exciting milestone, and our role is to ensure that excitement is not dampened by hidden defects discovered months after you move in.
The TW7 area features a mix of property ages, from Victorian terraces to modern townhouses built after 1980. If you are one of the buyers at Rothbury Row or another new development in the area, our snagging survey gives you a documented list of issues to present to your developer. We have extensive experience inspecting properties across the full spectrum of construction types found in this postcode, from traditional brick-built homes to more modern timber-frame or mixed-construction developments.
Our inspectors understand that different property types present different potential defect profiles. Flats may have shared infrastructure issues that require checking, while detached houses will have more external envelope to inspect. Whatever your property type, we apply the same rigorous standards to ensure every item meets the expected quality for a new-build property.

Based on our extensive experience inspecting new-build properties throughout the TW7 area and across London, we have identified several categories of defects that appear regularly in newly constructed homes. Understanding these common issues helps you know what to expect from your snagging survey and why professional inspection is so valuable.
One of the most frequent issues we encounter relates to paint finishes and decoration. We often find inconsistent paint coverage, paint splatters on glass or fixtures, and patches where the plaster shows through the paint. These cosmetic defects are annoying but are typically straightforward for the developer to rectify. However, without documentation from your snagging survey, these issues may be missed during the defects inspection period.
Another common category involves door and window installation. We frequently find that doors do not close properly, that locks are stiff or misaligned, and that window handles are loose or damaged. These issues affect your daily comfort and security, and they should be addressed by the developer before you move in. Our inspectors test every door and window in your property, documenting any issues with operation, alignment, or hardware.
Plumbing and electrical defects also appear regularly in new-build surveys. We find instances of low water pressure, improperly connected pipes that may leak, and electrical installations that do not meet current regulations. These issues are particularly important as they affect the safety and habitability of your home. Our detailed report ensures the developer cannot ignore these problems, protecting you from potential hazards.
We also commonly identify issues with extractor fans that do not vent properly, leading to condensation and damp problems, particularly in bathrooms and kitchens. Additionally, we frequently discover that insulation has not been properly installed in lofts or wall cavities, which can result in higher energy bills and reduced comfort. These defects may not be immediately visible but have significant long-term implications for your property.
Choose a convenient date and time for your snagging inspection in TW7. We offer flexible appointment slots to accommodate your moving schedule, including weekend availability for those with busy weekday commitments. Simply visit our quote page, enter your property details, and select a time that works for you.
Our qualified inspector visits your new-build property and conducts a comprehensive examination of all accessible areas, documenting defects with photographs and detailed notes. We systematically work through our 500+ point checklist, ensuring nothing is overlooked. The inspection typically takes between two and four hours depending on the size and complexity of your property.
Within 48 hours of the inspection, you receive a detailed snagging report listing all identified issues, complete with photographs, descriptions, and recommendations for rectification. Your report is formatted to make it easy to forward directly to your developer or their customer service team. We prioritise issues by severity so you can focus on what matters most.
Use your comprehensive report to request that the developer addresses identified defects before your warranty period expires or before you assume responsibility for repairs. Our reports are detailed enough to leave no room for the developer to dispute the existence of defects. We can also provide guidance on the next steps if you encounter any resistance from the developer.
Most new-build properties have between 100 and 200 defects that need addressing. Without a professional snagging survey, you may be responsible for repair costs that should be covered by your developer or warranty provider such as NHBC or LABC.
The TW7 postcode area, encompassing Isleworth and Osterley, has seen moderate new-build activity in recent years. One notable development is Rothbury Row, a collection of modern townhouses located near the centre of Isleworth. These properties, marketed by local estate agents, represent the type of new construction that benefits significantly from a professional snagging survey. With prices starting around £645,000 for a three-bedroom townhouse, ensuring these substantial investments are free from defects is essential.
The predominant housing stock in TW7 includes a mix of period properties from the Victorian and 1930s eras alongside more modern developments built after 1980. In certain postcode sectors such as TW7 7LB, the modern housing stock built after 1980 makes up the majority of properties, with 33 houses, 30 flats, and 7 other properties recorded in recent data. This variety means our inspectors are experienced in assessing both traditional brick construction and modern building methods.
When we inspect properties in the Isleworth area, we take into account the local environment and geography. The area's proximity to the River Thames means we pay particular attention to flood mitigation measures and drainage installations. We also check that properties have adequate ventilation given the local climate, ensuring that damp and condensation issues are less likely to develop in the future.
The regeneration of former industrial sites throughout TW7 has brought modern apartment complexes and townhouse developments to the area. These new-build properties often feature contemporary construction methods and materials that differ from traditional brick construction. Our inspectors stay current with modern building techniques to ensure we can identify any defects specific to these construction types, whether they involve structural panels, integral insulation systems, or modern roofing solutions.
A snagging survey provides a comprehensive inspection of your new-build property, covering all visible and accessible areas. Our inspectors check interior finishes such as plasterwork, paint, flooring, and doors, as well as kitchen and bathroom installations, electrical systems, plumbing, and the structural elements including the roof, walls, and damp proof course. We document every defect with photographs and descriptions, creating a detailed list you can present to your developer for rectification. The survey typically takes between two and four hours depending on the size of your property, and we examine over 500 individual check points to ensure nothing is missed.
Snagging surveys in the Isleworth TW7 area start from approximately £350 for a typical two-bedroom flat, with prices increasing for larger properties such as houses and townhouses. The cost reflects the size of the property and the number of individual check points our inspectors complete. Given that the average property price in TW7 exceeds £500,000, a snagging survey represents a minimal investment relative to the potential costs of undetected defects. For a four-bedroom detached new-build in the area, you would typically expect to pay around £500-£600, which remains a fraction of the potential repair costs if significant defects are discovered after you have moved in.
You should book your snagging survey as soon as possible after you receive the keys to your new property, but before you move in fully. This allows you to identify defects while the developer is still actively working on the site and can address issues more easily. Ideally, schedule the survey before the developer completes their own inspection, giving you an independent assessment of the property's condition. Many buyers in the TW7 area have found that booking within the first week of receiving keys yields the best results, as the developer is still on-site and can respond quickly to any issues identified. If you have purchased off-plan, we can also conduct a pre-completion inspection if access is arranged through your developer.
Your snagging report gives you documented evidence of defects that your developer is responsible for addressing under the terms of your warranty, typically provided by NHBC, LABC, or Premier Guarantee. Most developers have a defects liability period, usually lasting 12 to 24 months from completion, during which they are obligated to rectify issues. Your detailed report makes it much easier to negotiate with the developer and ensures nothing gets overlooked. In our experience, developers in the TW7 area are generally responsive to professional snagging reports, as they understand that documented defects are harder to dispute. If the developer fails to address issues within a reasonable timeframe, your warranty provider can become involved in ensuring remediation.
Yes, our inspectors are experienced in surveying all types of new-build properties in the TW7 area, including flats, terraced houses, semi-detached properties, and detached homes. Whether your property is a modern townhouse at a development like Rothbury Row or a newly constructed flat in Isleworth, we have the expertise to identify the specific defects common to each property type and construction method. We have inspected properties ranging from studio flats to large detached houses in the area, and our inspectors understand how different construction methods and materials can affect the types of defects you might encounter.
If you discover defects after moving into your property, you can still use your snagging report to contact the developer or warranty provider. The warranty period, typically ten years through NHBC, covers major structural issues, while the defects liability period usually covers minor issues for the first year or two. Having a comprehensive snagging report from the outset ensures you have documented evidence of the property's condition at handover. This is particularly important for issues that may develop over time, such as damp problems or sealant failures around windows, as your report provides a baseline showing the condition at the time you took ownership.
Properties in the TW7 area present some specific considerations due to their location near the River Thames and the types of ground on which they are built. Our inspectors pay particular attention to flood resistance measures, including door seals, damp proof membranes, and any below-ground waterproofing. We also check ventilation systems carefully, as properties built on former industrial land may have different moisture characteristics than other locations. Additionally, we examine the quality of window and door installations, as these are common defect areas in modern developments throughout the London area, including TW7.
