A new-build home can look finished at first glance while still containing defects that cost time, money and frustration later. Knowing how to prepare a snagging list gives you a clear record of unfinished work, poor workmanship and faults that your developer should address before, or shortly after, handover.
A useful snagging list is not simply a collection of minor cosmetic complaints. It is a practical document that identifies what is wrong, where it is located, why it matters and what evidence supports the issue. Prepared properly, it helps you communicate with the developer clearly and protects your position if repairs are delayed or disputed.
What is a snagging list?
A snagging list is a written schedule of defects, incomplete items and workmanship concerns found in a newly built or recently renovated property. A snag may be cosmetic, such as chipped paintwork or uneven sealant, but it can also point to a larger problem, including poorly fitted windows, roof defects, drainage issues, inadequate insulation or faulty heating controls.
The purpose is not to expect an entirely flawless property. Construction involves multiple trades working to tight programmes, and minor issues can arise. The key question is whether the work meets the standard promised in your contract, warranty documentation, specification and accepted building practice.
Some issues are easy to see. Others require experience, measuring equipment or a closer understanding of how a building should perform. This is why a professional snagging inspection can be particularly valuable where the property is expensive, the build quality appears inconsistent, or you are approaching a fixed completion date.
When to prepare a snagging list
Ideally, inspect the property before legal completion, when the developer still has the strongest incentive to resolve outstanding work. In practice, this is not always possible. Some developers restrict access before completion, while others offer a pre-handover demonstration that is too brief for a thorough inspection.
If you cannot inspect beforehand, carry out your review as soon as you receive the keys. Record defects promptly and notify the developer in writing. Most new homes come with a warranty period, but do not assume that waiting is risk-free. Early reporting creates a clear timeline and reduces the chance of a developer arguing that damage resulted from occupation, alterations or lack of maintenance.
For a refurbishment project, inspect at agreed milestones as well as at practical completion. It is usually easier and less disruptive to correct a defect before finishes, fitted furniture or external works conceal the cause.
How to prepare a snagging list that gets action
Start with a simple inspection template. A spreadsheet, notes application or printed room-by-room checklist can work well, provided every entry is specific. Avoid vague descriptions such as “bathroom poor” or “window not right”. They give the contractor little to investigate and make follow-up harder.
Each snag should include the precise location, a clear description, photographs and the date identified. Add a reference number so you can track correspondence and confirm when each item has been rectified. Where possible, explain the expected outcome rather than prescribing a repair method. For example: “Bedroom 2, north wall: vertical crack above socket outlet, approximately 1 mm wide and 300 mm long. Investigate cause and make good to match surrounding finish.”
Photographs should show both the wider location and a close-up of the defect. Use a ruler, tape measure or familiar object for scale where size matters. Video can help demonstrate intermittent faults, such as a leaking shower screen, sticking door or extractor fan that does not operate correctly.
For defects affecting safety, weather resistance or building performance, note the circumstances in which they occur. A stain beneath a window after rainfall, a cold area on an external wall, or water pooling against the property after a shower provides far more useful evidence than a photograph alone.
Inspect in a consistent order
A methodical approach prevents omissions. Begin outside, then work through the property room by room, finishing with loft spaces, garages, utility areas and shared external spaces where relevant. Do not rely only on artificial lighting. Inspect walls, ceilings and finishes in daylight or with a bright torch held at an angle, as this can reveal uneven plaster, poor paint coverage and surface damage.
Outside, check brickwork, render, roof coverings visible from ground level, gutters, downpipes, paving, drainage falls, fencing and the condition of external joinery. Look for cracked masonry, open joints, poor sealant, damaged roof tiles, standing water and gaps around service penetrations.
Inside, test rather than merely look. Open and close windows, internal doors and cupboard doors. Flush every toilet, run taps, check the shower, operate extractor fans, test light switches and sockets where safe to do so, and confirm that heating controls respond. Check that appliances supplied with the home are fitted, undamaged and working in line with the handover information.
Pay particular attention to kitchens and bathrooms. These areas combine plumbing, electrics, joinery, tiling and sealant, meaning small installation errors can quickly become leaks or damage to adjacent finishes. Check beneath sinks, around baths and shower trays, behind accessible pipework, and at the junctions between tiles, worktops and sanitaryware.
Separate minor finishes from urgent defects
Not every snag needs the same response. Categorising issues helps the developer deal with priorities and ensures serious concerns do not get lost among paint marks and scratches.
Urgent items include exposed electrical parts, loose balustrades, missing fire-stopping, water leaks, defective smoke alarms, insecure glazing and signs of significant movement. Report these immediately and request a clear plan for making the property safe.
Functional defects should follow next. These include windows that do not lock, heating that does not operate correctly, poor drainage, leaking pipework, failed extract ventilation and doors that do not close or seal properly. Cosmetic issues, such as dents, paint blemishes, uneven grouting or damaged trims, remain legitimate snags, but they can normally be scheduled after safety and performance matters are addressed.
Check the paperwork as well as the building
Your snagging list should be read alongside the sales specification, drawings, upgrade schedule, reservation documents and handover pack. A missing item may not be a workmanship defect if it was not included in the agreed specification. Equally, an item that looks acceptable may still fall short if the documents state a particular finish, appliance, fitting or landscaping provision.
Keep copies of emails, photographs, meeting notes and the developer’s responses. If a repair is agreed verbally during a site visit, send a short written confirmation afterwards. This creates an accurate record without making the process unnecessarily confrontational.
It is also sensible to retain manuals, test certificates, warranty information and meter readings supplied at handover. These documents can be needed when a fault is investigated, particularly where heating, ventilation, solar systems or electrical installations are involved.
Send the list clearly and set a reasonable process
Submit the completed list by email or through the developer’s formal aftercare system. Ask for acknowledgement, a named point of contact and target dates for inspection and rectification. A professional tone is usually more productive than a lengthy complaint. Focus on the evidence, the required outcome and the need for a clear timetable.
Give the developer reasonable access to inspect and carry out repairs, but do not mark an item as resolved until you have checked the finished work. A patch repair that differs noticeably in colour, a recurring leak, or a door adjusted so tightly that it damages the frame is not a satisfactory outcome.
Update your list after each visit. Record whether an item is open, awaiting inspection, repaired or requires further work. This prevents the common problem of items disappearing from an email chain simply because a contractor has attended the property.
When a professional snagging survey is worthwhile
A careful homeowner can identify many visible defects, especially if they allow enough time and work systematically. However, a professional surveyor can assess issues that are less obvious, distinguish normal settlement from potentially significant cracking, and identify defects that may affect the building’s durability, safety or value.
This is particularly useful for larger homes, properties with complex roofs, flats with communal elements, high-value upgrades, or developments where you have concerns about workmanship. A qualified inspection may identify concerns with insulation continuity, ventilation, drainage, roof detailing, external finishes and structural movement that are easy to miss during a brief handover visit.
HICH provides snagging surveys designed to give buyers and homeowners a detailed, practical record of defects, supported by building knowledge and repair-focused reporting. An independent report can also help keep discussions focused on the condition of the property rather than opinion.
A well-prepared snagging list is your opportunity to set a clear standard from day one. Take the time to inspect carefully, document what you find and pursue repairs with calm, factual persistence – it is far easier to resolve a defect before it becomes part of everyday life in your new home.
