What Happens If a House Survey Misses a Problem

You move into your new home and discover damp, cracking or a problem with the roof that wasn’t mentioned in your survey.

Naturally, your first question might be: why didn’t the surveyor spot it?

But when our solicitors investigate these cases, one of the first things they need to establish is whether the problem, or warning signs of it, were present when the surveyor inspected the property.

A defect discovered weeks or months later doesn’t necessarily mean the surveyor was negligent. What matters is what they should reasonably have identified at the time — and whether there’s evidence to establish that.

A Survey Is a Snapshot in Time

One of the difficulties with surveyor negligence claims is that a survey only records the condition of a property at the time of inspection.

Imagine a surveyor inspects a house in March, but the buyer doesn’t move in until September. When they arrive, they discover damp that wasn’t mentioned in the survey.

The problem is that the property’s condition may have changed during those six months. Damp, for example, can become more noticeable during wetter weather.

That doesn’t necessarily mean the surveyor overlooked it in March.

This is why the timing of the discovery matters. The longer the gap between the original inspection and the problem coming to light, the more difficult it can be to establish whether the defect, or signs of it, were present when the survey took place.

Some problems are easier to trace back than others. Significant structural defects, for example, may have developed over years rather than months.

What Should the Surveyor Have Noticed?

A surveyor isn’t expected to uncover every hidden defect in a property. But they should recognise warning signs that something may be wrong and, where appropriate, recommend further investigation.

Our solicitors describe this as following a “reasonable trail of suspicion.”

For example, a surveyor might notice cracking in a wall, signs of previous repairs or staining on a ceiling. Even if the underlying problem isn’t immediately obvious, those visible clues may suggest something needs looking into more closely.

Consider a significant crack in a wall that has been covered by plaster or paint. The crack itself might not be immediately visible, but were there other warning signs that should have prompted further investigation?

A surveyor may not be able to identify the full extent of a problem during a non-intrusive inspection. Recognising signs that something isn’t right, however, is an important part of their professional judgement.

Preserve the Evidence Before It Disappears

If you discover a problem that wasn’t mentioned in your house survey, evidence of the property’s condition can become particularly important.

Photographs and videos taken soon after discovering a defect can help establish what was found, particularly before repairs or other changes are made.

Earlier photographs can also be valuable. Estate agent listings, for example, may show signs of cracking, damp or other defects that weren’t identified in the survey report.

These images can help establish whether warning signs were visible around the time of the original inspection.

It’s understandable to want to fix a problem as quickly as possible, particularly if you’ve just moved into your new home. But removing damaged materials or carrying out repairs before the evidence has been properly recorded can make it harder to establish what was wrong and how long the problem may have existed.

Where repairs aren’t urgent, it may be sensible to seek professional advice before starting work. If there’s an immediate safety concern or a risk of further damage, necessary protective measures shouldn’t be delayed, but the condition should be documented as thoroughly as is safely possible.

What If the Defect Was Hidden?

Not every defect can be identified during a house survey.

Residential surveys are generally non-intrusive. Surveyors inspect what is reasonably accessible, but they don’t usually lift carpets, remove floorboards or open up walls to investigate what might be hidden underneath.

Our solicitors sometimes hear from homeowners who only discover a serious problem when they begin renovation work.

For example, someone might remove flooring or clear out a garage and uncover damage that wasn’t mentioned in their survey.

But that doesn’t necessarily mean the surveyor should have found it.

Much depends on what was accessible during the original inspection and whether there were visible signs suggesting a problem.

A garage filled with boxes, for instance, might prevent a surveyor from inspecting part of the building. However, staining on the ceiling could still provide a warning sign that something needs further investigation.

It’s this distinction between a genuinely concealed defect and a problem that should have raised concerns that can make surveyor negligence cases difficult to assess.

When May an Independent Assessment Help?

When our solicitors assess a potential surveyor negligence claim, one of the most useful pieces of evidence is an independent professional opinion on the original survey.

A second surveyor can examine the property, identify defects and consider whether there were signs the original surveyor should reasonably have noticed.

Sometimes homeowners have already obtained a second survey by the time they contact us. Where that report identifies significant problems that weren’t mentioned in the original survey, it can provide a useful starting point.

In our experience, the stronger cases often involve a significant defect that was missed completely, despite the original report giving that part of the property a clear rating.

However, a second report identifying a problem doesn’t automatically establish negligence. It needs to be considered alongside what the original surveyor could reasonably have identified at the time.

Look Back to the Day of the Survey

Discovering an unexpected problem after buying a home can be frustrating, particularly when you paid for a professional survey to help you understand the property’s condition.

But establishing whether a surveyor was negligent involves looking beyond the defect itself.

Sometimes, the evidence of what was visible before the purchase can be just as important as the problem discovered afterwards.
