Protect your new build investment in Harborne with a detailed professional snagging inspection








Harborne has seen steady new build activity in recent years, including McHugo Homes' boutique townhouse scheme at The Orchards on Tennal Road, Centrick's Serpentine Mews on Serpentine Road, and the large-scale New Garden Square regeneration project by Moda on Hagley Road in neighbouring Edgbaston delivering up to 1,600 new homes. With average property prices in B17 sitting around £377,000 - and premium new build townhouses priced from £495,000 - a new build here represents a serious financial commitment. Our surveyors work regularly across Harborne and know what Birmingham's developers typically leave behind.
The Home Builders Federation reported in March 2025 that 93.7% of new build buyers found defects after moving in, with over a quarter discovering more than 15 individual snags. Research from Coventry University puts the average at over 140 issues per property, with 4% classified as health and safety risks. In our B17 inspections, we find issues ranging from hairline plaster cracks and poorly sealed windows to incorrectly fitted insulation and drainage deficiencies on sloped sites. If you are buying new in Harborne, we would recommend booking a survey within the first two weeks of receiving your keys, while your developer's team is still active on site.

A snagging survey is a room-by-room inspection of a newly built property carried out by a qualified surveyor. The goal is to identify every defect, from cosmetic blemishes to safety-critical issues, and compile them into a formal report that your developer is obligated to address.
B17's new build market is dominated by boutique townhouses built by smaller independent developers rather than national volume housebuilders. Properties like The Orchards on Tennal Road and Serpentine Mews on Serpentine Road offer premium specifications - air source heat pumps, underfloor heating, Hansgrohe bathrooms - but smaller developers may have less established NHBC quality management processes than a Persimmon or Taylor Wimpey. This makes independent snagging surveys particularly important for Harborne buyers: at £495,000-£600,000+ for a new build townhouse, the cost of a survey is less than 0.1% of the purchase price.
Standard snagging inspections in B17 now include thermal imaging as part of the survey. Using infrared cameras, our surveyors can detect problems invisible to the naked eye - missing insulation behind walls, cold bridges where heat escapes the building envelope, and early signs of moisture ingress that could lead to damp and mould.
This is particularly relevant for Harborne's new build townhouses, which typically include air source heat pumps, underfloor heating, and mechanical ventilation systems - all of which need correct installation to function as specified. Thermal imaging confirms whether your developer actually installed these components to specification, not just on paper. Given the premium price point of B17 new builds, this level of verification is not optional - it is essential.

Under your NHBC or equivalent warranty, you have two years from completion to report defects to your builder - including cosmetic issues. After that period, only structural problems are covered for the remaining eight years. Booking a snagging survey within the first few weeks of completion gives your developer maximum time to fix everything while they are still legally responsible. The longer you wait, the harder it becomes to prove a defect was present at handover.

Research from Coventry University found that new homes average 141 defects per property, with 4% classified as health and safety risks. In our B17 inspections, Harborne's newer townhouses tend to show issues specific to their construction type: the modern M&E installations (underfloor heating, air source heat pumps, mechanical ventilation) require precise commissioning that is easy to overlook. Properties on Harborne's sloped sites can also have drainage challenges that were not caught during construction. Across B17, the most frequently reported defects we find include:
Many of these defects are not immediately obvious when you first collect the keys. Paint imperfections become visible in natural daylight. Plaster cracks develop as the building dries out over weeks. Drainage problems only appear when it rains heavily. A trained snagging surveyor knows exactly where to look and what tools to use.

Enter your B17 postcode and property details on our booking form. We will match you with a qualified snagging surveyor who covers the Harborne area and confirm pricing based on your property size.
The best time for a snagging inspection is within the first two weeks of completion. We can also arrange a pre-completion inspection before you legally take ownership, giving your developer time to fix issues before handover.
The inspection takes 2 to 4 hours depending on property size. Our surveyor checks every room, tests all systems, and uses thermal imaging equipment to identify hidden defects behind walls and ceilings.
Your photographic report arrives within 48 hours. Each defect is documented with annotated images, room location, and severity rating. You send this directly to your developer as your formal defect notification.
Since 2022, the New Homes Quality Board has required developers to offer pre-completion inspections (PCIs) to buyers. This means you can arrange a snagging survey before you legally complete on your B17 new build - typically during the final fix stage when most finishes are in place.
A pre-completion inspection has clear advantages. Defects identified before completion can be fixed by the developer as a condition of the sale. You avoid the disruption of having tradespeople in your home after you have moved in. And you have stronger leverage - the developer wants to complete the sale and will prioritise getting your snag list resolved.
Post-completion surveys remain the more common choice. Most B17 buyers book within the first month of moving in. At this point, the property has been in use long enough for certain defects to become apparent - doors that stick as humidity changes, radiators that do not balance correctly, or drainage that backs up during heavy rain. Our recommendation for B17 buyers: if your developer offers pre-completion access, take it. If not, book within the first month of moving in. Either way, do not wait until problems become obvious - by that point, seasonal drying and shrinkage may have masked some defects while revealing others.
New builds in B17 should achieve an EPC rating of B or higher - the government's minimum standard for newly constructed homes. Older parts of Harborne score as low as E, F, or G due to pre-1919 construction with minimal insulation. If your new build's EPC rating does not match the developer's specification, your snagging surveyor can flag this as a defect. Thermal imaging will show exactly where the insulation shortfall exists.
A snagging survey in the B17 Harborne area starts from around £320 for a 1-2 bedroom property. For a typical 3-4 bedroom new build townhouse - the most common new build type in Harborne - expect to pay between £380 and £450. Larger properties of 5 bedrooms or more start from £480. These prices usually include thermal imaging. Optional extras like drone roof inspections cost an additional £50 to £95. At Harborne's average new build price of £495,000-£600,000+, the survey cost is less than 0.1% of your purchase and can save thousands in unresolved defects.
The ideal time is within the first two weeks after you receive the keys to your new build. This gives you the maximum window to report defects under your two-year builder's warranty. If your developer offers a pre-completion inspection, booking before legal completion is even better - defects can be resolved as a condition of the sale. Avoid waiting more than a few months, as seasonal factors like central heating use and moisture from drying materials can mask or reveal different types of defects.
A standard snagging inspection for a 3-bedroom property in B17 takes approximately 2 to 3 hours on site. Larger detached homes or properties with complex layouts including underfloor heating and smart home systems - common in Harborne's boutique townhouses - may take up to 4 hours. After the on-site inspection, your surveyor needs an additional 1 to 2 working days to compile the photographic report with annotated images and categorised defects. Most clients receive their report within 48 hours of the inspection.
Your developer is legally required to fix defects reported within the first two years under the NHBC, LABC, or equivalent warranty scheme. If they refuse or delay unreasonably, you can escalate through the warranty provider's formal complaints procedure. The snagging report acts as documented evidence of each defect. In persistent cases, the warranty provider can appoint independent inspectors and compel the developer to act. Having a professional report from a qualified surveyor strengthens your position significantly compared to a DIY checklist.
You can create your own snagging list, and many buyers do spot obvious issues like paint defects or scratched surfaces. The difference is that a professional surveyor has specialist equipment including thermal imaging cameras, moisture meters, and spirit levels that detect problems hidden from the naked eye. Issues like missing insulation, cold bridges from incorrectly commissioned heat pumps, and concealed plumbing leaks will not show up on a visual inspection alone. Given that the average new build contains 141 defects and a professional survey costs from £320, most B17 buyers find the investment worthwhile.
Flats and houses share many common snag types - plaster cracks, paint defects, and poorly fitted doors appear across all property types. Flats in B17 often have additional issues specific to multi-unit buildings: sound insulation between floors and walls that fails to meet Building Regulations, communal area finishes that do not match the specification, and fire door closers that are incorrectly adjusted. With 27% of B17 housing being purpose-built or converted flats, these are common concerns for local buyers.
A thorough snagging survey includes all external areas within your property boundary. Your surveyor will inspect brickwork and render, roof tiles and ridge lines, fascias and soffits, guttering and downpipes, driveways and pathways, fencing, and any landscaping specified in your purchase contract. For properties in B17 developments, shared areas like parking bays and bin stores are also noted if they fall within the scope agreed with your surveyor.
A snagging survey is specifically designed for new build properties and focuses on construction defects, finish quality, and compliance with the agreed specification. A building survey (RICS Level 3) is a comprehensive structural assessment typically used for older or unusual properties. For a new build in B17, a snagging survey is the appropriate choice. If you are buying an older Victorian or Edwardian property in the Harborne area - which makes up a large portion of B17's housing stock - a building survey would be more suitable.
