What Happens on Snagging Inspection Day: A Room-by-Room Walkthrough
Booking a snagging inspection for the first time can feel a little daunting. If you have just reserved or completed on a new build in Warwickshire, Coventry, Leicester or anywhere else across the Midlands, you may be wondering what an inspector actually does once they arrive, whether you need to be there, and whether the whole thing will cause a fuss with your developer.
The good news is that a snagging inspection is a calm, methodical and entirely routine process. By the end of this article you will know exactly what to expect on the day, so any nervousness about picking up the phone melts away.
First, What Snagging Is (and What It Is Not)
A snagging inspection is a thorough visual check of the quality, finish and workmanship of your new home. Your inspector walks through every accessible part of the property, inside and out, noting anything that falls short of the standard a reasonable buyer should expect. These items are called snags, and they range from a paint run on a skirting board to a poorly sealed shower tray.
It is important to be clear about one thing from the start. Snagging does not cover anything structural, and it is not a structural survey. It does not assess the structural integrity of your home, and it is not a formal building regulations compliance check, because that responsibility sits with Building Control and your warranty provider. Snagging assesses the quality of workmanship and finish only. What you get is an expert, independent assessment of the things your developer is responsible for putting right, backed by clear photographic evidence.
How Long Does It Take, and When Should It Happen?
Most inspections take somewhere in the region of a few hours, and the exact time depends on the size of the property and the quality of the finish. A one-bedroom apartment will naturally take less time than a large detached family home. As a rough guide, allow the best part of a morning.
Timing matters too. Ideally the inspection happens before you move in, so your developer has time to fix everything without disrupting your daily life. If you already have the keys, do not worry: a snagging inspection remains valuable at any point during the first two years of your warranty, when defects with your home's finish are covered.
The Room-by-Room Walkthrough
A good inspector works to a consistent order so nothing is missed. Here is roughly how the day unfolds.
The inspection usually begins at the entrance and hallway, checking the front door for alignment, smooth operation, weather seals and locks, along with the paintwork, skirting and any flooring where different rooms meet.
Moving into the living and dining areas, the inspector examines walls and ceilings under good light for cracks, uneven plaster, tape lines showing through paint and untidy finishing around trim. Sockets, switches and light fittings are checked to confirm they sit flush and level and are properly finished.
The kitchen receives close attention, as it is one of the most defect-prone rooms in any new home. Cupboard doors and drawers are opened and closed, worktops are checked for scratches and correct sealing, tiling and grout are examined, and integrated appliances, the sink, taps and extractor are tested.
Bathrooms and en-suites are the other room where problems commonly cluster, largely because they concentrate plumbing into a small space. The inspector looks at sealant around baths, basins and shower trays, checks tiling and grouting, confirms that the toilet flushes and fills correctly, and makes sure extractor fans are actually connected and working rather than simply spinning.
In the bedrooms, the focus returns to decoration, windows, wardrobes where fitted, and again the sockets, switches and radiators. The staircase and landing are tested for creaks, secure handrails and even, consistent steps, and the inspector checks that carpet or flooring is properly laid and secure underfoot.
Where accessible, the loft or roof space is one of the most revealing areas. Inspectors look for correctly laid insulation, and crucially they check that extractor and soil pipes actually vent to the outside rather than discharging moist air into the roof, a common fault that can lead to damp and mould if left unaddressed.
The garage, if you have one, is checked for the door mechanism, brickwork, the slab and any meter or consumer unit housed there. Outside, the inspector turns to the exterior and grounds: brickwork and mortar, render, guttering and downpipes, fascias and soffits, the driveway and paths, fencing, gates and any turf or landscaping.
Windows and doors are checked individually rather than sampled, because operation, seals, locks, handles and glazing quality can vary from one unit to the next. Finally, the electrics, plumbing, heating and drainage are assessed at a visual and functional level: sockets and switches, the heating switched on so radiators can be felt for even warmth, visible pipework and traps checked for leaks, and drains and inspection chambers checked at ground level.
Where Thermal Imaging Comes In
One of the most valuable parts of a modern snagging inspection is thermal imaging, which is included as standard at no extra cost with our snagging checklist reports. A thermal camera detects temperature differences that are completely invisible to the naked eye, revealing issues that a standard visual check would miss entirely.
In practice, thermal imaging can reveal missing or poorly installed insulation, thermal bridging (weak points in the building fabric where heat escapes more easily), air leakage around doors and windows, and areas of trapped moisture. These are exactly the kind of hidden defects that quietly push up your heating bills for years, so catching them while your builder is still responsible is genuinely worthwhile. It is worth noting that thermal imaging cannot be included in a Pre-Completion Inspection, because NHQB guidelines do not permit it at that stage.
How Many Snags Is Normal?
If your report comes back with a long list, please do not panic. Snags are the norm, not the exception, and finding them is exactly the point. As the Home Builders Federation puts it, "new homes are carefully constructed, but snags and defects can still occur, as they are a hand-crafted product", built outdoors in all weathers by many different trades.
The scale is striking. According to the Home Builders Federation National New Homes Customer Satisfaction Survey published in March 2025, 93.7% of new build buyers reported problems such as snags and defects to their builder since moving in, and over a quarter (26.2%) reported more than fifteen snags. The picture in the following year's survey, published in March 2026, was broadly the same, with 93% of buyers reporting problems and around one in five saying the number was fewer than they expected. A professional inspection typically picks up many more items than a homeowner would spot alone. The great majority are minor and cosmetic: plastering defects are the single most common category of snag, accounting for roughly 20 to 30 per cent of all reported defects, with paint-related defects a close second at around 15 to 25 per cent. What matters is getting them documented and fixed.
Your Rights: Inspections, the Code and Your Warranty
Under the New Homes Quality Code, administered by the New Homes Quality Board (NHQB), developers registered with the scheme must allow you to appoint a suitably qualified inspector to carry out a Pre-Completion Inspection on your behalf before you legally complete. The inspector uses a standard NHQB checklist. There are limits: the inspector may not be allowed unaccompanied access, no ladders or roof void access are permitted, and thermal imaging is not allowed. For that reason many buyers follow up with a fuller snagging inspection once they have the keys. You can read more about our approach to both on our pages covering Pre-Completion Inspections and snagging checklist reports.
Your warranty sits behind all of this. Most new homes are covered by a warranty from NHBC, LABC or Premier Guarantee, and they broadly follow the same structure: a two-year period during which your builder is responsible for putting right defects reported to them, followed by insurance cover for the remaining years up to ten, which protects against specified structural problems only. This is why the first two years matter so much, and why an early inspection is such a sensible investment. The Code is clear on timescales too: in most situations the developer must be able to settle an after-sales issue or problem within 30 days, unless there is a significant reason for a delay.
The Questions Nervous Buyers Ask Most
Do I need to be present? No. You are welcome to attend, and many people like to so the inspector can talk them through what has been found, but it is entirely your choice.
Should the builder attend? They do not need to. The inspection is carried out independently on your behalf.
Will it cause delays? A snagging inspection does not give you the right to delay or refuse completion, and in normal circumstances it will not hold anything up. It simply documents issues for your developer to fix.
What happens to the report afterwards? You receive a detailed report, delivered within two working days, with clear descriptions and photographs of every issue.
How do I submit it to the developer? You can send it yourself, or we can send a copy directly to your builder to get things moving.
What if the builder disputes items? This is where independence really counts. A professional report carries weight, and we provide ongoing support throughout the remedial process, helping you hold your developer to the right standard. It also helps to understand tolerances: industry standards such as the NHBC Standards set out acceptable limits for finishes (for example, plastered surfaces are expected to be flat within about 3mm when checked against a straight edge), so not every tiny variation counts as a defect, but a great deal does.
