■ Approximately 84% of people with home-buying experience 'prioritize' the warranty period
While people often focus on conditions such as location, design, and price when buying a home, many are also concerned about 'post-purchase warranties' and 'after-sales service.'
Defects discovered after moving in, and aging that progresses over the years. To what extent are housing warranty periods and maintenance systems prioritized against such risks?
Therefore, this time, in collaboration with Cuore Home Co., Ltd., we conducted a survey on 'long-term housing warranties and after-sales service' targeting 300 men and women across the country who answered in a preliminary survey that they 'have experience buying a home or are considering buying one.'

*As a rule, totals may not equal 100% because figures are rounded to the nearest second decimal place.
■ 84.0% answered they 'prioritize' the warranty period
First, we asked to what extent they prioritize the warranty period when purchasing a home.
As a result, 36.3% said they 'very much prioritize' it, and 47.7% said they 'somewhat prioritize' it, revealing that a total of 84.0% of people prioritize the warranty period. On the other hand, only 12.7% said they 'do not prioritize much,' and 3.3% said they 'do not prioritize at all.'
We asked for the reasons for each answer, and here are some of them.
Reasons for 'prioritizing' the warranty period
- Because it is a house I will live in for a long time. (30s, male)
- Because I would be in trouble if there were defects immediately after purchasing. (30s, male)
- Because I think defects and areas requiring repair will definitely appear. (40s, male)
- Because a long warranty period is proof that they are confident in the property. (50s, female)
- Because housing repair costs are extremely high, so I think warranties are important. (50s, male)
Reasons for 'not prioritizing' the warranty period
- I didn't know there was a warranty period. (40s, female)
- I have a feeling that 10 years are basically included. (40s, female)
- Because various defects tend to appear after the warranty period has passed and years have gone by. (50s, female)
- I bought a used property, so I wasn't conscious of it at all. (50s, male)
From those who prioritize it, there were many voices saying, 'I want peace of mind precisely because it is an expensive purchase,' and 'defects can be found after moving in.' There were also opinions that see the length of the warranty period as 'an expression of confidence,' suggesting that it is also serving as an index for measuring trust in housing quality.
On the other hand, for those who do not prioritize it, there were cases where a lack of awareness of the warranty system was in the background, such as 'I wasn't conscious of it because it was a used property' or 'I didn't know about the existence of warranties in the first place.' Also, there were voices questioning the effectiveness of the warranty itself, stating that 'defects appear after the warranty period passes.'
■ 37.3% answered 'about 20 years' as the ideal warranty period
Next, we asked about the number of years they think is ideal for a housing warranty period.
The most common answer was 'about 20 years' at 37.3%.
This was followed by 'about 30 years' at 23.0% and 'about 10 years' at 21.3%.
Also, 14.3% of people answered '50 years or more,' and if you add the 4.0% for 'about 40 years,' the number of people who desire a long-term warranty of 30 years or more reaches about 40% of the total.
Degradation of housing equipment and repairs of exterior walls and roofs often become necessary after 10 years, so those seeking warranties that can cover that period stood out.
■ 32.7% answered they 'have felt anxious' about post-purchase maintenance or regular inspections
Next, we asked if they have ever felt anxious about post-purchase maintenance or regular inspections.
As a result, 32.7% said 'yes,' and 67.3% said 'no.'
We also asked what kind of anxiety they felt, and here are some of them.
What kind of anxiety is it?
- Because when things break, they break at the same time. I'm afraid of having to pay at once. (30s, female)
- Because I don't know when I should do what, or how much it will cost. (40s, female)
- Things like how much it will cost if a defect occurs. (40s, female)
- I'm anxious about whether they will respond properly. (40s, female)
- The construction company went bankrupt and I could no longer receive maintenance. (50s, male)
Broadly speaking, two issues emerge: 'lack of transparency in costs' and 'reliability of the contractor.' Furthermore, there were actual experiences where people could no longer receive warranties or maintenance due to the bankruptcy of a construction company, showing how important it is to confirm the management foundation and warranty system of the construction company at the time of purchase.
■ 58.3% hope for 'regular inspections' as after-sales service
Finally, we asked what kind of support would make them feel secure as after-sales service.
The most common answer was 'regular inspections' at 58.3%.
This was followed by 'a service that shows the standard for repair costs' at 40.7%, 'consultation handling for renovations/repairs' at 39.7%, and 'emergency dispatch response' at 39.0%.
It is clear that what home buyers are seeking is not 'support that waits passively,' but 'proactive support' that allows them to check the condition regularly and foresee future costs.
The awareness of wanting to discover defects early through regular inspections and understand the standard for repair costs in advance can be said to be an expression of the attitude of viewing a house not as something that is 'bought and done with,' but as something to 'keep maintaining.'
■ Summary
From this survey, we found that more than 80% of those with home-buying experience prioritize the warranty period, and about 80% of people desire '20 years or more' as the ideal number of warranty years.
Also, about 1 in 3 people have anxiety about maintenance, and the content is mainly about the lack of transparency in costs and the reliability of the construction company. Regarding after-sales service, the results showed high expectations for support that leads to long-term peace of mind, such as regular inspections and the visualization of repair costs.
When choosing a home, in addition to the quality of the building itself, paying attention to the post-purchase warranty system and the richness of after-sales service seems to be a key point for living comfortably for a long time.
