Have the door installation checked afterwards?

Hello,
my husband and I bought a house a few months ago. A breakthrough was made in a load-bearing exterior wall by a company (however without an invoice) and an additional door with concrete lintels was installed. So far so good. We are satisfied. Recently, an acquaintance told me that this was an intervention in the structural integrity and that actually a structural engineer should have been commissioned and the building authorities should have been notified. That made me feel very uneasy. Is it possible that something might still happen now, for example the ceiling collapsing? Can this still be checked afterwards?
Thank you very much in advance for answers

Hello,

My husband and I bought a house a few months ago. A company (although without an invoice) made an opening in a load-bearing exterior wall and installed an additional door with concrete lintels. So far, so good. We are satisfied. Recently, an acquaintance told me that this was an intervention in the structural integrity and that actually a structural engineer should have been commissioned and the building authority notified. That made me feel really bad. Is it possible that something could still happen now, for example, the ceiling could collapse? Can this still be checked afterwards?

Sigh, this is the topic of "referees and football fans" – there are always people who think they know everything better than others, even if only by hearsay. Even if you had the opening made "without fuss," the executing company, according to your statement, did install concrete lintels. If your acquaintance were right, half of Heinsberg and the surrounding area would have to collapse; there, at most 30% of the houses are built by a construction company, the rest are created as "neighborly help" :D

Probably no answer here will truly calm you down; hire a building expert to inspect the work, then the feeling of well-being will return as well.

Kind regards
