You collect the keys to a brand-new home expecting clean finishes, working fittings and a property built to the standard promised. Then you spot a cracked tile, a sticking window, uneven sealant or a heating system that does not perform as it should. It is reasonable to ask: do builders fix snags? In most cases, yes – but getting defects fully acknowledged and properly remedied often depends on how they are identified, recorded and followed up.
A new-build home can have minor cosmetic issues alongside more significant concerns involving workmanship, drainage, insulation, ventilation or compliance. The developer remains responsible for putting right defects that fall within their contractual obligations and warranty arrangements. However, not every issue is resolved quickly, and not every initial repair is satisfactory. That is where a clear, independent record can protect your position.
Do builders fix snags after completion?
Builders should rectify genuine snags reported after completion, particularly where they relate to defective workmanship, incomplete work or items that do not meet the agreed specification. Most developers operate a customer care process, usually asking buyers to log defects through an online portal, email address or dedicated aftercare team.
In practice, the experience varies. Some issues are booked in and resolved promptly. Others may be disputed as damage, wear and tear, normal settlement or an acceptable construction tolerance. There can also be delays while the developer waits for a subcontractor, orders replacement materials or groups several jobs into one visit.
The key point is that completion does not remove the builder’s responsibility for defective work. It does, however, change the practical balance. Before completion, you have more leverage because outstanding matters can affect whether you are ready to complete. Once you have moved in, you need to rely on the developer’s aftercare procedure, your purchase contract and the relevant warranty process.
What counts as a snag?
A snag is a defect, fault, incomplete item or quality issue found in a new-build property. It can be as obvious as a damaged kitchen unit or as concealed as missing insulation, poor roof detailing or inadequate ventilation.
Some snags are cosmetic but still worth recording. Poor paint finishes, scratched glazing, chipped worktops, gaps in mastic and misaligned doors may not affect structural safety, yet they can reduce the quality and value of a home you have paid for in new condition. They should not simply be dismissed because they are small.
Other defects demand more urgent attention. These can include water ingress, leaking pipework, loose electrical fittings, faulty fire doors, drainage problems, roof defects, unsafe balustrades, poor heating performance and signs of heat loss. A problem that appears minor can sometimes point to a wider issue in the build process.
It is also worth separating a snag from normal movement. New homes can experience some drying shrinkage and minor settlement as materials acclimatise. Fine cracks may occur, particularly around joints and openings. That does not give a builder a free pass to ignore every crack, but the cause, location and extent need to be assessed before deciding whether remedial work is required.
The first two years matter
The first two years after legal completion are often the most important period for reporting defects. Under common new-home warranty arrangements, the builder is generally responsible for rectifying defects caused by failure to meet the warranty provider’s technical requirements during this initial period. Your exact rights will depend on your contract, developer and warranty documentation, so keep these documents accessible.
Do not wait until the final month of the two-year period if you can avoid it. Defects are easier to investigate while the evidence is clear, and earlier reporting gives the builder a fair opportunity to arrange repairs. It also creates a dated record showing that the issue was raised within the relevant period.
At around 18 to 22 months, a two-year warranty inspection can be particularly valuable. By then, the home has been lived in through changing weather conditions and heating cycles, which can reveal movement, moisture, thermal performance and workmanship issues that were not obvious at handover. An independent inspection provides a structured report before the builder’s initial liability period is due to end.
Why builder snagging lists are not always enough
Many buyers receive a brief handover check or are encouraged to create their own list while moving in. This can identify visible defects, but it is not the same as a professional snagging survey.
A homeowner is unlikely to inspect every room systematically, test accessible components, assess finish quality against expected standards or recognise warning signs of non-compliant work. There is also a practical difficulty: once you have moved in, you are managing furniture deliveries, utilities, school runs and the rest of daily life. Small defects are easily missed.
An independent snagging inspection is not designed to create conflict with the developer. Its purpose is to establish evidence. A detailed report can describe the defect, record its location with photographs, explain the likely concern and set out the action required. This makes it harder for an issue to be lost in a vague list such as “mark on wall” or “door problem”.
Professional reporting is particularly useful where defects are repeated across the property, where repairs have already failed, or where there are concerns about building regulations, warranty standards or safety. It gives you a clear basis for requesting remedial action without relying on opinion alone.
How to report snags effectively
Start by reporting each issue in writing through the developer’s stated customer care route. Be factual and specific. Include the room or external location, a short description, the date noticed and clear photographs or video where appropriate. If the issue affects safety, security, water penetration, heating or electrical operation, state this plainly and ask for an appropriate response timescale.
Keep copies of every submission, acknowledgement, appointment date and repair outcome. If a contractor attends, note what was done and whether the defect has genuinely been resolved. A repair that looks acceptable on the day may fail again after rain, normal use or temperature changes.
It is sensible to give the builder reasonable access and an opportunity to rectify confirmed defects. At the same time, do not allow a snag to disappear from the record simply because someone has attended. If the repair is incomplete or creates a new defect, report it again straight away.
For a larger number of issues, a formal snagging report helps you present the findings in a logical format rather than sending a stream of separate emails. It can also prevent the common problem of the developer fixing only the most visible items while more technical concerns remain unaddressed.
When should you arrange an independent inspection?
The best timing depends on where you are in the purchase. A pre-completion inspection can identify visible issues before you take ownership, although access is subject to the developer’s agreement and the property’s readiness. A post-completion snagging survey is often the practical choice, especially when access before completion is limited.
You should consider an inspection sooner rather than later if you notice damp, leaks, cracks that are widening, cold areas, poor ventilation, recurring drainage issues or workmanship that appears inconsistent throughout the home. These are not defects to leave until a routine visit months later.
A back-snagging inspection is useful after the builder says repairs are complete. It checks whether work has been finished to an acceptable standard and whether previously reported issues remain. This can be particularly reassuring where several trades have attended over different visits.
New Homes Inspections provides evidence-led snagging and warranty inspections for buyers across the Midlands and South Yorkshire, helping homeowners present clearly documented defects to their developer.
If the builder does not fix the snags
If the developer disputes, delays or repeatedly fails to resolve defects, remain calm and keep the matter documented. Ask for a written response explaining their position and the proposed remedy. Refer to the wording of your contract, warranty documents and any relevant technical standards where appropriate.
Escalation routes differ between developers and warranty providers. You may be able to use a formal complaints process or, depending on the circumstances, seek support through the relevant new-homes redress or warranty route. An independent survey report will not guarantee a particular outcome, but it can strengthen your case by separating evidenced defects from general dissatisfaction.
Avoid arranging your own permanent repairs to a disputed issue without first notifying the builder, unless urgent action is necessary to prevent damage or protect safety. Unauthorised work can make it harder to establish the original cause and may complicate responsibility. If emergency work is unavoidable, photograph the issue first and retain invoices.
Protect the condition and value of your home
A builder should fix valid snags, but the process works best when defects are reported early, described accurately and checked after repair. Treat the first two years as an active protection period, not a deadline to think about later.
A new home deserves more than a quick visual check at handover. Careful inspection and a well-kept evidence trail give you the confidence to ask for the standard of workmanship you paid for – and the best chance of seeing it delivered.
