Is a home inspection necessary?

When buying a home, it is essential to make sure that the property does not have hidden problems that could lead to costly repairs. There are several construction pathologies that affect the safety, comfort and value of a property. In this guide, we explain the 10 most common pathologies in homes and how to detect them in time.

1. Cracks in walls and ceilings

Cracks can indicate anything from simple material movement to serious structural problems. The most worrisome are those that run through load-bearing walls or follow diagonal patterns.

How to spot them: Watch for deep or expanding cracks, especially near doors and windows.

2. Moisture and leaks

Moisture can appear due to capillarity (from the ground), seepage (rain, damaged roofs) or condensation (poor ventilation).

How to spot them: Look for dark stains, musty odor or peeling paint on ceilings and walls.

3. Problems in the electrical installation

Poor electrical installation poses a great risk. Old wiring, overloaded sockets or faulty differentials can cause short circuits and fires.

How to detect them: Check for exposed wires, frequently blown fuses or malfunctioning plugs.

4. Plumbing deficiencies

Water leaks, corroded pipes or unstable water pressure can cause major problems in a home.

How to detect them: Listen for noises in pipes, check for dripping faucets or brown water in drains.

5. Defects in the deck and roof

Roof deterioration can cause leaks and thermal insulation problems.

How to detect them: Look for broken shingles, dampness in the roof or leaks on rainy days.

6. Poor thermal and acoustic insulation

Poor insulation causes heat loss in winter and overheating in summer, as well as disturbing noise between dwellings.

How to detect it: If you notice drafts near cold windows or walls in winter, the insulation may be poor.

7. Problems in floors and coatings

Floors may exhibit unevenness, excessive crackling or loose tiles, indicating settlement or poor installation.

How to detect them: Walk around the house and look for strange movements on the floor or broken tiles.

8. Misaligned windows and doors

If doors and windows do not close properly, this may be a symptom of structural movement or installation defects.

How to detect it: Try opening and closing doors and windows several times to check its adjustment.

9. Hidden pests

Termites, woodworm or humidity can weaken the structure of the house without you noticing it with the naked eye.

How to spot them: Look for traces of sawdust, hollow wood or strange noises in the night.

10. Gas installations in poor condition

Poor maintenance of the gas system can be dangerous and lead to leaks.

How to detect it: Gas odor, orange flames on the stove or heaters that turn off by themselves can be warning signs.
