The concern
The deadline expires and any defects are no longer covered under warranty.
What we did
Structured inspection, formal complaint according to SIA, support during renegotiation.
What was the goal?
Rights respected, negotiations calm and objective.
What was the initial situation?
You live in your house for two years, get used to its little quirks, and eventually tune them out. Then the letter arrives reminding you of the warranty period, and suddenly the question is back: What did we actually miss? Anyone who lets this period go unused forfeits rights that can no longer be enforced.
Without this inspection, we would have wasted four positions that have now been repaired.
Ownership, Lake Zurich region
What have we accomplished?
I systematically prepared for the inspection and went through the house piece by piece: exterior, roof, facade, interior, and building services. I documented each finding photographically and categorized it objectively. This resulted in a formal notice of defects, which was submitted to the sellers in a timely manner and in a form that could be used as evidence.
What was the result?
The owners have protected their rights. The notice of defects was submitted on time, the negotiation process with the general contractor was based on facts, and every point was documented in a comprehensible manner.
