On the exciting journey of buying a home, one of the biggest fears is hidden defects. Here we explore the most expensive ones when purchasing a second-hand property and what you should keep in mind to spot them in time.
1. Structural problems
Structural problems, such as cracks in walls or foundations, are the most costly hidden defects. They are not always visible to the naked eye, but they can lead to very expensive repairs. Before buying, it is essential to carry out a detailed inspection with experts.
How to detect structural problems?
- Hire a professional: an architect can identify subtle signs in cracks, settlement or unevenness.
- Check the repair history: any previous work can offer clues about past problems.
2. Chronic damp
Chronic damp can go unnoticed at first, but over time it causes structural and health damage. Stains on walls, ceilings or basements can be warning signs. Catching it early is key to avoiding costly treatments.
How to prevent damp problems?
- A professional inspection with a thermographic camera and hygrometers to identify moisture even when it is not visible.
- Good ventilation throughout the home to prevent build-up.
3. Obsolete or deficient electrical systems
Old or faulty electrical installations pose a significant risk: they can cause breakdowns and, above all, represent a safety hazard. Check their condition before you buy.
How to assess them?
- A professional inspection to analyse the quality and safety of the installation.
- Documentary review: request the certificates from the most recent inspections or repairs.
Frequently asked questions
When should I have the inspection done?
Before signing any purchase commitment. That way you will avoid surprises and have the information you need to negotiate.
How much does a home inspection cost?
The cost varies depending on the property, but it is a highly worthwhile investment compared with the potential expenses arising from an undetected hidden defect.
Can I negotiate the price based on the problems found?
Yes. Once the problems have been identified, you can negotiate the price or request repairs before closing the deal.
