Introduction
When it comes to buying or selling a house, many clients in Portugal confuse the terms “technical inspection” and “vistoria”. Although they may seem similar, they are very different processes – and the right choice can determine whether the purchase is made with confidence or ends in regret.
In this article, we explain the main differences between an independent technical inspection of a house, apartment or building and a simple survey, and why this is essential before signing the Promissory Contract of Purchase and Sale (CPCV) or the deed.
What is an inspection?
An inspection is, in most cases, a quick visual check carried out by the seller, the real estate agent or even the buyer on an informal basis. Sometimes, the buyer also hires inspection companies with no know-how and no equipment, who just take photographs
It serves to confirm basic aspects, but:
- Does not evaluate structure
- Does not detect hidden leaks
- Does not use technical equipment
- It has no legal or technical value
What is a technical inspection?
Technical inspection is a professional, independent and impartial process conducted by specialized technicians and engineers.
It goes far beyond visual observation and includes:
- Structural assessment (walls, foundations, roofs)
- Electrical and plumbing inspection
- Moisture and infiltration detection with thermal cameras
- Technical inspection of roofs and chimneys, using thermographic drones in areas that are difficult to access.
- Detailed technical report, with photographs, interpretations of thermographic readings and technical recommendations with a legislative framework
- Reports drawn up by experienced and certified engineers with legal validity
Main differences between survey and technical inspection
| Appearance | Inspection | Technical Inspection |
| Who does it | Seller, buyer, real estate agent | Specialized technician or engineer |
| Depth | Visual, superficial | Complete with advanced equipment |
| Hidden problems | Not identified | Identifies infiltrations, cracks, structural risks |
| Written report | Not normally | Yes, with technical and legal validity |
| Value for negotiation | Little or none | High: you can save thousands of euros |
| Impartiality | Partial (seller’s interest) | Totally independent |
Why is it important before the CPCV?
The CPCV involves a significant financial down payment.
Without a technical inspection, the buyer can make commitments without knowing it:
- That the roof is leaking
- That the pipes are obsolete
- That there are serious structural cracks
- That the electrical installation is unsafe
With a technical report from Inspect One, the buyer gains negotiating power and can even avoid a bad deal.
Conclusion
The difference between a survey and a technical inspection is clear:
- The normal inspection looks at the surface.
- The technical inspection reveals the truth.
At Inspect One, we help buyers, sellers and investors make safe decisions with independent and impartial technical reports.
