Professional new-build inspections across the Marazion and Helston area. Get your snag list before you complete.
Buying a new-build property is one of the biggest financial decisions you'll make, and even brand-new homes can have hidden defects. Our snagging surveys in Marazion TR17 give you a comprehensive inspection before you complete, identifying issues that developers should fix under their warranty obligations. We check everything from cosmetic finishings to structural elements, giving you leverage to request repairs before the builder walks away.
The TR17 postcode area, covering Marazion and the market town of Helston, has seen steady new-build activity in recent years with developments from Persimmon Homes and Gilbert & Goode bringing modern properties to the market. With typical new builds revealing anywhere from 100 to 200 snags, our detailed report ensures you don't inherit someone else's problems. The local area geology, including areas with former mining activity and clay deposits, also means our inspectors pay particular attention to ground stability and drainage that might affect newer properties.
Cornwall's unique geography adds another layer of consideration for new-build properties in this area. The local geology around Marazion and Helston includes Devonian slates and sandstones, with areas of granite and superficial deposits in valley areas. Our inspectors understand how these ground conditions can affect newer properties, particularly around drainage and potential subsidence risk. We also check for issues specific to the region, such as proper ventilation in properties built with modern construction methods.

The TR17 area, covering Marazion and surrounding villages, has seen steady new-build activity in recent years. While developments like The View on Porthleven Road and Trevenson Meadows bring modern homes to the market, even quality builders can miss defects during the rapid construction pace. Our inspectors in TR17 regularly find issues ranging from poorly finished plasterwork and ill-fitting doors to more serious problems like inadequate drainage and structural concerns that could cost thousands to put right.
The local economy around TR17 includes significant employers like Royal Naval Air Station Culdrose, which creates consistent demand for housing from military personnel and their families. This steady demand has encouraged continued development, but the speed of construction often means corners get cut. Our inspectors understand the local housing market dynamics and know what to look for in properties built for this specific buyer demographic. We also see effects from the tourism industry, with some buyers purchasing new builds as holiday lets or second homes, which can affect how defects are prioritised by developers.
Over 90% of new-home owners discover snags with their property, according to industry research. Getting a snagging survey before you complete gives you practical leverage. Most developers are responsive to snagging reports during the defects liability period, but once you've completed and moved in, getting them to return for repairs becomes significantly harder. Our detailed reports document every issue with photographic evidence, making it straightforward to submit to your builder or warranty provider. The NHBC 10-year warranty that covers most new builds requires proper documentation within the first two years, and our surveys ensure you meet those deadlines.
Cornwall's building heritage also influences what our inspectors look for. Traditional properties in the area use local stone, granite, killas slate, and lime render, but newer builds often incorporate different materials and construction methods. Our team understands how these modern construction techniques, including timber frame elements used by some developers, can behave differently from traditional Cornish masonry. We check that new properties are built to appropriate standards for the local environment, particularly regarding moisture exposure from the coast and drainage in valley areas.
Market Data 2024
Our snagging surveys in Marazion TR17 follow a systematic room-by-room and element-by-element approach. We inspect the exterior walls, roof, foundations where accessible, and all internal rooms. Our inspectors examine the quality of workmanship throughout, checking that surfaces are level, fixtures are properly fitted, and all mechanical and electrical systems function correctly. We test plumbing by running water and checking for leaks, and we test electrical outlets and lighting to ensure everything meets current safety standards.
Given the local environment near the coast and river valleys, we pay particular attention to damp penetration, ventilation, and drainage around the property exterior. Properties in TR17, particularly those near the River Cober or coastal areas around Porthleven, face higher exposure to moisture and salt air. Our inspectors ensure that render, seals, and drainage systems are properly detailed to prevent future problems. We also document any signs of movement or cracking that might indicate subsidence issues, which can occur in areas with certain clay soils or former mining activity.
The legacy of mining in Cornwall adds another dimension to our inspections. Some properties in the Marazion and Helston area were built on or near old mine workings, and our inspectors are experienced in identifying signs of ground instability that might affect newer properties. We look for characteristics that might indicate mundic brick or other mining-related construction materials used between 1900-1950, which can degrade dramatically when exposed to moisture and cause serious structural issues. While this is more common in older properties, we assess whether new builds in historically mined areas show any concerning signs.
Our inspection also covers the specific warranty requirements that apply to your property. Most new builds in the TR17 area are covered by NHBC warranties, which provide 10-year protection with the builder responsible for the first two years. We ensure our reports are formatted to meet warranty provider requirements, making it straightforward to invoke the defects liability period. Whether your property is covered by NHBC, LABC, or Premier Guarantee, our detailed documentation supports your claim for rectification work.
Choose a convenient date and time for your snagging inspection. We offer flexible appointments across the TR17 area, including weekends to accommodate buyers who work during the week. You'll receive instant confirmation and our pre-arrival information pack, which includes guidance on what to expect and how to prepare for the inspection. We can often accommodate short-notice bookings, which is particularly useful if your developer has given you limited advance warning of completion dates.
Our qualified inspector visits your new-build property and conducts a thorough visual inspection lasting 2-4 hours depending on property size. They check all accessible areas, test fixtures and fittings, and photograph every defect they find. For larger properties, the inspection may take longer as we systematically work through each room and external area. You don't need to stay for the entire inspection, but many buyers find it helpful to be present for at least part of the time to see issues firsthand and ask questions.
Within 24-48 hours of the inspection, you receive a comprehensive written report with photographs of every issue. The report categorises defects by severity, distinguishing between minor cosmetic issues and major problems requiring urgent attention. Each item includes clear recommendations for rectification and references to relevant building regulations or warranty requirements. Our reports are detailed enough to submit directly to your developer or warranty provider without additional clarification.
Your report gives you everything needed to submit a formal complaint to your builder or developer. If required, we can provide additional support explaining the report to the developer or warranty provider. We can advise on the specific warranty terms that apply to your property and help you understand what remedies you're entitled to under the NHBC or other warranty scheme. Our goal is to ensure you have the documentation and knowledge needed to get issues resolved satisfactorily.
If your new-build property is in an area with former mining activity, mention this to your inspector. Cornwall has a legacy of mining, and some properties were built on or near old mine workings. Our inspectors are experienced in identifying signs of ground instability that might affect newer properties in the Marazion area. Additionally, if you're buying near the coast around Porthleven, mention proximity to salt air as this affects how we assess external finishes and drainage systems.
The Marazion and Helston catchment area has seen new housing development from several volume housebuilders. Persimmon Homes operates Trevenson Meadows on TR13 0FB, offering 2, 3, and 4-bedroom homes with prices starting from around £230,000. Gilbert & Goode are developing The View on Porthleven Road, with properties ranging from approximately £295,000 to over £450,000. While these developments technically fall just outside the TR17 boundary, they serve the broader Marazion and Helston housing market that our TR17 surveyors cover. Both developments are popular with families and military personnel from RNAS Culdrose.
Both Persimmon and Gilbert & Goode are established national and regional builders, but even the most reputable developers produce properties with defects. Common issues our inspectors find with these types of developments include inadequate sealing around windows, incomplete landscaping, drainage issues, and cosmetic defects in finishings. The rapid pace of construction in the housing industry means that corners can be cut, and a professional snagging survey is your best protection. We see similar patterns across developments from different builders, which reflects industry-wide challenges rather than specific builder failures.
Most new builds in this area use traditional masonry construction with brick and block cavity walls, though some newer properties incorporate timber frame elements. Whatever construction method your property uses, our inspectors have the expertise to identify defects and ensure your new home meets acceptable standards. We check that cavity insulation is properly installed, that wall ties are correctly spaced, and that the structural elements meet building regulations. All properties we inspect are covered by the NHBC 10-year warranty, and our reports provide the documentation you need to invoke the builder's two-year defects liability period.
The local planning context also affects what we inspect. Helston has a significant Conservation Area covering its historic town centre, and some new developments on the outskirts must meet specific design codes. While most new builds won't be listed buildings, we check that exterior finishes and details are consistent with planning approvals. Our inspectors understand Cornwall's building regulations and ensure your property meets all relevant standards before you complete.
Our inspectors in the Marazion area regularly encounter specific defect patterns in newly built homes. Cosmetic issues are most common, including poorly finished paintwork, uneven or bubbling plaster, and tiles that are not properly aligned. These might seem minor, but they indicate the overall quality of workmanship and can mask more serious problems underneath. We frequently find doors and windows that don't close properly, which affects security, energy efficiency, and can lead to draughts and moisture penetration. In properties near the coast, we also see premature weathering of external finishes due to salt air exposure.
Mechanical and electrical defects also appear regularly in new builds across TR17. These include plumbing issues such as slow drains, leaking joints, or poorly connected pipework. Electrical problems range from non-functioning outlets to more serious safety concerns like inadequate earthing or incorrect wiring. Our inspectors test all accessible electrical points and plumbing fixtures, identifying issues that would otherwise only become apparent after you've moved in and potentially caused damage. Given the moisture-prone local environment, we pay particular attention to electrical safety in bathrooms and wet rooms.
External defects are particularly important in the TR17 area due to local weather conditions. Properties near the coast face exposure to salt air and strong winds, while those in valley areas deal with higher moisture levels. We commonly find inadequate drainage fall away from properties, incomplete external rendering, and defects in roof tiling or flashing. These issues can lead to penetrating damp and structural problems if not addressed. Our thorough external inspection ensures all weatherproofing details are correct before you complete on your new property.
Drainage is a critical concern in this area, particularly for properties built on ground with high clay content or near the River Cober. We check that surface water drains away from the property foundation properly and that soakaways function correctly. Poor drainage can lead to subsidence or heave, which are particularly concerning in areas with historical mining activity or shrink-swell clay. Our inspectors also verify that gutters and downpipes are properly connected and that there's adequate separation between damp-proof courses and ground levels.
A snagging survey is a detailed visual inspection of a new-build property that identifies defects, unfinished work, or substandard workmanship. Our inspector checks every accessible area including walls, ceilings, floors, windows, doors, plumbing, electrical systems, and external areas. We test fixtures and fittings, look for signs of damp or structural issues, and document everything with photographs. The report then categorises issues by severity and provides recommendations for rectification. In the TR17 area, we also specifically check for issues related to coastal exposure, drainage in clay-prone areas, and signs of movement that might indicate ground instability from former mining activity.
The duration depends on property size and complexity. A typical 2-bedroom apartment takes around 2 hours, while a large 4-bedroom detached house may require 3-4 hours. Our inspector works systematically through the property, testing all systems and documenting defects thoroughly. Larger properties with more complex layouts or those with multiple defects may take longer. You don't need to stay for the entire inspection, but many buyers find it helpful to be present for at least part of the time to see issues firsthand and discuss them with the inspector.
Ideally, book your snagging survey for when you have final completion access to the property but before the official handover date. This gives you time to negotiate repairs with the developer before you legally own the property. We recommend scheduling the survey at least a week before your planned completion date to allow time for the report and any negotiations. If you're buying off-plan, we can also inspect at key stages during construction, though the most common timing is the pre-handover inspection when the property is essentially complete.
While developers are not required to attend their own inspections, many choose to send a site manager or representative. Having the developer present can be beneficial as they can see issues directly and often begin arranging repairs immediately. However, our reports are detailed enough to submit to the developer whether or not they attended the inspection. We recommend you notify your developer of the inspection date so they have the opportunity to join if they wish. Some buyers prefer the inspector to attend alone to ensure a thorough, unbiased assessment without pressure from site staff.
If your builder refuses to address issues identified in our report, you have several options depending on the severity of the defects. For issues covered under the NHBC warranty (which covers most new builds for 10 years), you can contact NHBC directly to report the problem and invoke their dispute resolution service. Our detailed reports with photographic evidence strengthen your position significantly. For serious structural or safety issues, you may be able to withhold completion until repairs are satisfactory, though this depends on your specific purchase contract terms. The NHBC provides protection for years 3-10, while the builder is responsible for the first two years under the defects liability period.
Absolutely. Even smaller properties can have significant defects that cost hundreds or thousands to put right. A 1-2 bedroom apartment might have issues with plumbing in the bathroom or kitchen, electrical problems, or damp from inadequate ventilation. The cost of a snagging survey is relatively small compared to potential repair bills, and it gives you about your purchase. Many buyers find that even new apartments have 50-100 snags that need addressing. In the TR17 area, where properties near the coast may have specific moisture-related issues, a survey provides valuable assurance regardless of property size.
The TR17 area has specific considerations that our inspectors address. Properties near the coast, such as those close to Porthleven, face accelerated weathering from salt air and may have drainage issues from high water tables in valley areas. We check that external renders and sealants are appropriate for coastal exposure. Properties built on or near former mining land may show signs of ground movement, so we look for cracking and subsidence indicators. The local clay soils can cause shrink-swell movement, so we pay attention to drainage around foundations. Finally, we verify that properties meet Cornwall-specific building regulations for the local environment.
