Tettonis Engineering has far exceeded my expectations. Vasili, the Principal Engineer, responded swiftly and scheduled a preliminary chat for the next day. I expressed my concerns, and he was very thorough in providing the history of the site. Within the same week, he conducted an on-site investigation and implemented a wall crack monitoring system.
