When Does a New-Build Defect Become Wear and Tear?

A leaking gutter, deteriorating bathroom sealant or damaged kitchen worktop can raise a surprisingly difficult question:
Is this still a new-build defect, or has it become ordinary wear and tear?
The answer is rarely based on the issue alone.
It also depends on:
how old the home is;
when the problem first appeared;
how the item has been used;
whether it has been reasonably maintained;
the material and expected durability;
and whether the failure points back to the original installation.
A gutter joint leaking during the first year may reasonably be reported to the developer. The same joint leaking after ten years may be more likely to need normal maintenance—unless there is evidence that it was incorrectly installed from the outset.
Similarly, bathroom silicone should not be expected to last forever. However, it should generally cope with normal use and appropriate cleaning for a reasonable period. Sealant pulling away shortly after completion is different from sealant gradually deteriorating after years of showers, cleaning and movement.
This guide explains how to assess the difference without assuming that every problem is automatically the developer’s responsibility—or accepting “wear and tear” without question.
During the first two years after completion, it is generally reasonable to report problems that may have been caused by defective materials, poor workmanship or incorrect installation.
After the initial builder warranty period, most ten-year new-build warranties provide more limited insurance cover. They do not usually continue the developer’s responsibility for every finish, fitting or maintenance issue until the home is ten years old.
Using NHBC Buildmark as a common example, its cover is divided into a two-year builder warranty and a further eight years of insurance cover for damage caused by defects in certain parts of the home. The later period is therefore not simply eight additional years of general snagging cover. Other providers may use different policy wording, limits and exclusions, so homeowners should always check their own documents.
The most useful question is not simply:
“How old is the home?”
It is:
“Has this item performed reasonably for its age, material, installation and level of use?”
The first two years: the builder warranty period
The first two years are commonly referred to as the builder warranty, defects or after-sales period.
During this time, your developer should normally be your first point of contact where an element of the home appears not to have been completed to the required standard.
The Consumer Code for Home Builders describes the first two years as the period in which the builder is responsible for putting right qualifying defects that develop in the home. The New Homes Quality Code also requires registered developers to provide an after-sales service for at least two years and explain their responsibility for dealing with snags and defects. Which code applies will depend on the developer, reservation date and warranty arrangements for your property.
This does not mean that every mark, breakage or maintenance task must be dealt with by the developer.
They may reasonably decline responsibility where the problem has resulted from:
accidental damage;
misuse;
alterations carried out after completion;
a lack of reasonable maintenance;
or ordinary deterioration through normal occupation.
However, an item should not automatically be dismissed as wear and tear merely because you have moved in and started using it.
A door should open and close under normal use. A worktop should cope with appropriate kitchen use. A shower enclosure should remain watertight when properly used and maintained.
Where something fails unusually early, it is reasonable to ask whether the cause lies in the product, installation or workmanship.
Years three to ten: not an extended snagging period
One of the most common misunderstandings is that a ten-year warranty means the developer must repair defects throughout the entire ten years.
That is not normally how the cover works.
For example, NHBC describes years three to ten as insurance cover for damage caused by defects in specified parts of the home. Its homeowner guidance lists items such as foundations, certain walls, roofs, load-bearing parts of floors and some external glazing among the parts typically covered, subject to the policy’s full terms, limits and exclusions.
This is materially different from general cover for:
decorative finishes;
kitchen units;
handles and hinges;
sealants;
internal fittings;
surface wear;
or routine maintenance.
NHBC’s current policy wording also excludes gradual deterioration, wear and tear, neglect and failure to carry out appropriate maintenance. Other warranty providers have their own wording, so the applicable policy should always be checked rather than assuming all ten-year warranties are identical.
By year nine or ten, a leaking gutter joint, worn sealant or loose cupboard hinge will often be viewed in the context of age and maintenance.
That does not mean an original construction problem becomes acceptable merely because time has passed. If there is evidence that an element was incorrectly installed, repeatedly failed or was reported during the builder warranty period, its history remains relevant.
Time alone does not decide responsibility
There is no single date on which every unresolved issue automatically changes from a defect into wear and tear.
Different components:
have different purposes;
are made from different materials;
receive different levels of use;
require different maintenance;
and have different reasonable service lives.
A loose handle after eight years of daily use is not the same as a handle that was loose on completion.
A scratched worktop caused by dragging a heavy appliance is different from a worktop joint swelling because it was inadequately sealed.
A gutter blocked by leaves requires maintenance. A gutter that has leaked from an incorrectly assembled joint since the property was built may indicate an original defect.
The age of the item is therefore only one part of the assessment.
Six questions to ask
When deciding whether to report something, work through the following questions.
1. When did the problem first appear?
A failure that develops shortly after completion is more likely to justify investigation than the same failure after many years of service.
That does not prove that it is a defect, but it provides useful context.
Recording the date matters because a problem first reported during the two-year period may remain outstanding after that period has ended.
2. Has the item been used normally?
Normal household use should not cause a properly selected and installed product to fail immediately.
However, damage resulting from impact, overloading, excessive heat or inappropriate use is unlikely to be treated in the same way as a failure under ordinary conditions.
3. Has reasonable maintenance been carried out?
A new home still requires maintenance.
Gutters need clearing. Boilers require servicing. Ventilation filters may need cleaning. External finishes eventually require attention. Sealants need monitoring and, over time, renewal.
NHBC’s homeowner guide, for example, recommends cleaning gutters at least annually to remove leaves and debris and identifies a range of other routine care tasks.
The developer may have a reasonable argument where a failure was caused or worsened by neglected maintenance.
They have a weaker argument where:
maintenance was not yet reasonably due;
the item failed unusually early;
the problem was unrelated to maintenance;
or the homeowner was not provided with relevant product instructions.
4. Does the failure indicate poor installation?
The visible issue is not always the underlying cause.
Signs that may warrant further investigation include:
repeated failure in the same location;
poor alignment;
inadequate support;
fixings pulling out;
joints that were never properly sealed;
or a component that has never worked correctly.
5. What material was used?
Materials do not all wear at the same rate.
A laminate worktop and a granite worktop serve the same broad purpose, but they respond differently to heat, moisture, scratching and impact.
The expected performance should therefore reflect the actual material used.
However, a lower-cost material must still be:
suitable for its intended location;
installed correctly;
properly finished;
and capable of coping with normal use.
A developer cannot reasonably excuse poor sealing by saying that the worktop was “only laminate”.
6. What evidence is available?
Photographs, dates, previous correspondence and repair records can make the difference between a clear issue and an argument based on memory.
Evidence is particularly important where the developer says:
the damage was caused by the homeowner;
the item has not been maintained;
the problem was not reported during the relevant period;
or the current condition is simply normal ageing.
Common examples
Leaking gutter joints
Gutters are exposed to weather, temperature changes, debris and movement. They also require periodic cleaning.
A gutter problem could therefore result from:
a blocked outlet;
accumulated leaves;
a displaced or ageing seal;
poor alignment;
inadequate falls;
insufficient brackets;
or an incorrectly connected joint.
During the first two years
A leaking joint during the first year or two is reasonable to report, particularly where the gutter is visibly clear and water is escaping through the connection rather than overflowing because of a blockage.
The developer should be given the opportunity to inspect the cause.
A leaking joint is not automatically proof of defective workmanship, but neither should it automatically be dismissed as homeowner maintenance so soon after completion.
Several years later
As the home ages, weather exposure, movement and seal deterioration become increasingly relevant.
The homeowner should also be able to demonstrate that the gutters have been reasonably checked and cleared. NHBC’s general homeowner guidance recommends cleaning gutters at least once a year.
At or after ten years
By the end of a typical ten-year warranty period, replacing a worn gutter seal or carrying out local repairs is more likely to be treated as routine ownership and maintenance.
The position may be different where there is evidence of a more fundamental construction issue, such as an incorrect fall, insufficient support or repeated leakage documented from the early life of the property.
The history matters.
A ten-year-old leak that appeared last month is different from a leak that was first reported in year one and never properly resolved.
Bathroom silicone and sealants
Silicone is a flexible, replaceable component. It is not expected to last for the entire life of the building without attention.
Its condition can be affected by:
the quality of the initial application;
movement between adjoining materials;
ventilation;
moisture;
cleaning products;
physical scrubbing;
and ordinary ageing.
What may indicate an early defect?
It is reasonable to question silicone that:
pulls away shortly after completion;
contains obvious gaps from the outset;
has not bonded to one of the surfaces;
allows water behind a bath, tray or worktop;
or has been applied over dirt, moisture or an unsuitable surface.
These issues may point to preparation or application rather than ordinary wear.
What may indicate maintenance or ageing?
Over time, silicone can:
discolour;
develop mould staining;
lose flexibility;
become damaged during cleaning;
or separate as adjoining materials move.
Regular cleaning is normal and should not cause correctly applied silicone to fail almost immediately. However, repeated aggressive scrubbing, abrasive tools or unsuitable chemicals may reduce its service life.
A sensible approach is to clean it regularly but gently, follow relevant product guidance and replace the sealant when it no longer forms an effective watertight joint.
The balanced expectation
It is reasonable to expect the original silicone to withstand ordinary bathroom use and suitable cleaning for a meaningful period.
It is not reasonable to expect it to remain untouched indefinitely.
The question is whether it failed prematurely because of the original application or gradually reached the point where replacement became normal maintenance.
Kitchen worktops
The durability of a kitchen worktop depends heavily on its material.
Laminate worktops
Laminate worktops are widely used and can provide good service, but they are generally more vulnerable to:
cuts and scratching;
impact damage;
high heat;
and moisture entering joints or exposed core material.
A chip caused by dropping a heavy pan is likely to be accidental damage.
Swelling around a sink cut-out or worktop joint shortly after completion may indicate that an edge or joint was not adequately sealed.
That distinction is important because both issues may present as “damage”, but they have very different causes.
Granite and engineered stone
Stone worktops generally resist ordinary surface wear better than laminate, although they can still chip or crack.
Where a crack appears without a known impact, questions may need to be asked about:
support;
the position of cut-outs;
installation;
movement;
or an existing weakness in the material.
A stone worktop is not indestructible, but the type and location of the failure should be considered alongside its age and use.
Material quality does not excuse poor installation
A lower-cost product may show wear sooner than a premium one.
That does not mean it can be:
damaged at handover;
inadequately supported;
incorrectly jointed;
or left vulnerable to moisture because the installation was incomplete.
Material choice helps determine reasonable durability. It does not remove the requirement for suitable workmanship.
Flooring
Flooring is subject to daily use from the moment the homeowner moves in.
Normal wear may include:
gradual carpet flattening in frequently used routes;
light scratches caused by furniture;
small surface marks;
and wear around entrances.
Potential installation concerns may include:
joints separating shortly after completion;
boards lifting or moving excessively;
loose or hollow tiles;
recurring moisture damage;
or defects caused by poor subfloor preparation.
The fact that a floor has been walked on does not automatically make every problem wear and tear.
The relevant question is whether it has performed reasonably under ordinary domestic use.
Doors, hinges and handles
Doors and ironmongery often require minor adjustment as a new home dries and settles.
A hinge that loosens after years of repeated use may be a straightforward maintenance item.
A door that has never latched, repeatedly drops or catches because the frame is misaligned may point back to installation.
Look at the pattern:
Did it work correctly when you moved in?
Has it gradually changed?
Has it already been adjusted several times?
Are the fixings secure?
Is movement elsewhere in the opening contributing?
That history is often more informative than the current symptom alone.
Decoration and plaster cracking
Paintwork naturally accumulates marks, scuffs and small dents as a home is occupied.
New homes also undergo drying and settlement, which can cause fine cracking around joints and openings.
Minor cracks do not necessarily indicate a serious defect.
However, further review is sensible where a crack:
continues to widen;
repeatedly returns after repair;
is associated with water penetration;
appears alongside significant movement;
or begins to affect doors, windows or other elements.
A technical measurement can also require context. Something being outside a recognised tolerance does not, by itself, explain its cause, seriousness or practical effect.
Maintenance begins before the warranty ends
Some homeowners understandably assume that maintenance begins once the two-year period has expired.
In reality, maintenance starts when you take ownership.
Tasks may include:
ventilating the home and managing condensation;
cleaning gutters;
servicing heating and hot-water systems;
cleaning ventilation filters;
protecting worktops from heat and moisture;
monitoring sealants;
maintaining external finishes;
and following manufacturer care instructions.
The developer remains responsible for qualifying defects during the applicable period, but the homeowner is still expected to look after the property.
These responsibilities can overlap.
For example:
You are responsible for clearing leaves from a gutter.
The developer may still be responsible for correcting a gutter installed with an inadequate fall.
You are responsible for cleaning a shower enclosure.
The developer may still be responsible for sealant that was incomplete or detached soon after handover.
You are responsible for using a laminate worktop appropriately.
The developer may still be responsible for a sink cut-out that was not properly sealed.
Maintenance should not be treated as a blanket excuse for defective work. Equally, a warranty should not be treated as a substitute for maintaining the home.
What to do during the first two years
If you notice a problem during the builder warranty period:
Record it as soon as possible.
Photograph the wider area and the close-up detail.
Note when it first appeared.
Explain whether it affects normal use.
Check any relevant maintenance or product instructions.
Report it to the developer in writing.
Keep all responses and repair records.
Recheck the item after any work is completed.
Avoid making a technical diagnosis unless you have evidence.
Instead of writing:
“The gutter has been installed incorrectly.”
A clearer initial description may be:
“Water is escaping through the gutter joint above the rear door during rainfall. The gutter is visibly clear of debris and the issue was first noticed on 12 July.”
This records what you can observe without overstating what has caused it.
The New Homes Quality Code says homeowners should report issues as soon as possible so developers can meet their after-sales responsibilities. It also requires registered developers to provide clear processes for receiving and dealing with those issues.
What to do before the two-year period ends
Do not wait until the final week to work out what remains outstanding.
A few months before the relevant date:
review every previously reported issue;
check whether repairs have genuinely resolved the problem;
revisit components that have failed more than once;
inspect areas affected by water;
test doors, windows, taps, heating and ventilation;
photograph outstanding items;
and send the developer a clear written record.
Make sure you know the exact start and end dates shown in your warranty and completion documents.
Also check which consumer code applies to your purchase. Developers may operate under the Consumer Code for Home Builders or the New Homes Quality Code, and the applicable complaints and redress route can differ.
What to do during years three to ten
Once the builder warranty period has ended, begin by checking the actual terms of your structural warranty.
Do not assume that the words “ten-year warranty” mean every problem remains covered.
Ask:
Is the affected component included?
Has the issue caused damage covered by the policy?
Is there a minimum claim value or excess?
Is wear and tear excluded?
Is maintenance evidence required?
Was the issue first reported during the builder warranty period?
Could another policy, guarantee or insurance apply?
For example, a minor leaking gutter joint in year seven may be a maintenance repair rather than a structural warranty claim.
Damage to a covered part of the home caused by a qualifying construction defect may be assessed differently.
When uncertain, contact the warranty provider with a factual description and ask whether the issue falls within the policy.
What happens after ten years?
After a typical ten-year structural warranty expires, most ongoing repairs, deterioration and maintenance become part of normal homeownership.
That may include:
replacing ageing sealants;
repairing gutter joints;
renewing worn finishes;
adjusting fittings;
replacing components that have reached the end of their useful life;
and maintaining external elements.
This does not mean every serious construction problem discovered after ten years is automatically without any possible remedy. The legal and contractual position can be complicated and will depend on the circumstances.
For an ordinary homeowner deciding whether to report a minor component failure, however, age, service life and maintenance will carry considerably more weight than they did during the first two years.
How the SnagClear App helps
The difference between a defect and wear and tear often depends on the history.
A photograph taken today may show the condition, but it will not necessarily show:
when the problem started;
whether it was previously reported;
how it changed;
what the developer said;
or whether an attempted repair failed.
SnagClear helps homeowners create a clear, organised record by allowing them to:
record each issue with photographs;
add the room, element and description;
generate a clear PDF report for the developer;
keep snag information together;
and track repairs and status changes over time.
This is particularly useful for recurring problems. A timeline showing that a gutter joint was reported, repaired and then leaked again can be much more valuable than a new email written months later.
Record issues while the details are still clear.
Download SnagClear, add your first snag in less than 30 seconds and generate a free preview report.
You can also use the free SnagClear Homeowner Pack to help organise your final checks before the builder warranty period ends.
Frequently asked questions
Is everything covered during the first two years?
No.
The first two years are an important builder warranty and after-sales period, but accidental damage, misuse, normal deterioration and maintenance issues may still fall outside the developer’s responsibility.
The issue should be assessed according to its cause rather than assuming that the date alone determines the answer.
Does the ten-year warranty cover wear and tear?
Ordinary wear and tear is not normally the purpose of structural warranty cover.
For example, NHBC’s current Buildmark wording excludes gradual deterioration, wear and tear, neglect and failure to carry out appropriate maintenance. Homeowners should check the wording of their own provider and policy version.
Is a leaking gutter after two years still worth reporting?
Yes, particularly if it first appeared within the builder warranty period or may result from the original installation.
Provide the developer with photographs, dates and information about any relevant maintenance.
Whether they are ultimately responsible will depend on the cause, policy terms and history of the issue.
How long should bathroom silicone last?
There is no single reliable lifespan that applies to every product and installation.
Its durability depends on the product, preparation, movement, ventilation, use and cleaning.
It is reasonable to expect correctly applied silicone to withstand normal use and appropriate cleaning for a meaningful period. It will nevertheless require replacement eventually.
Can cleaning damage bathroom silicone?
Regular, suitable cleaning is part of normal bathroom care.
Aggressive scrubbing, abrasive tools or incompatible chemicals may damage the surface or reduce its useful life. Check the cleaning guidance for the relevant sealant and surrounding materials where available.
Is a laminate worktop expected to wear faster than granite?
Generally, laminate is more vulnerable to heat, impact, scratching and moisture entering exposed edges or joints.
Granite and engineered stone are typically more resistant to ordinary surface wear but can still chip or crack.
The material affects reasonable durability, but both must be suitable and correctly installed.
Can a developer simply call something wear and tear?
They can give that opinion, but it is reasonable to ask how they reached it.
Ask them to consider:
the age of the item;
when the problem first appeared;
the type of failure;
the expected maintenance;
and whether the installation has been inspected.
Keep the discussion factual and ask for the response in writing.
What if I reported the problem within two years but it remains unresolved afterwards?
Keep evidence of the original report and continue following the developer’s complaints procedure.
Depending on the developer, warranty and applicable consumer code, you may also have access to a warranty resolution service, dispute resolution scheme or the New Homes Ombudsman Service. Check the deadlines and eligibility rules that apply to your property.
Final thought
A defect does not become wear and tear simply because time has passed.
Nor does a ten-year warranty make the developer responsible for every component throughout the first decade.
A fair assessment considers:
when the problem began;
how the item was installed;
what material was used;
how it has been used;
what maintenance was reasonably required;
and whether it has performed as expected for its age.
Report issues early. Keep photographs and written records. Complete reasonable maintenance and retain evidence where relevant.
Most importantly, focus on the cause and history of the problem rather than the label placed on it.
That gives you the clearest basis for deciding whether to approach the developer, contact the warranty provider or arrange the repair as part of maintaining your home.
