point for claims adjusters handling long-tail construction defect losses: determining when property damage actually occurs and which policy period is triggered.
Mycon General Contractors, Inc. alleges that continuous CGL coverage from 2013 through 2025 should have triggered defense and indemnity obligations as facade damage progressed over time at a McKinney commercial project. The damage reportedly evolved from early foundation cracking in 2016 to falling veneer and major facade failures by 2024. That timeline places adjusters squarely in the middle of one of the industry's most debated issues: whether progressive or continuous damage triggers multiple policy years, and how to allocate responsibility across carriers.
Each insurer reportedly denied coverage based on the position that the damage did not occur during its respective policy period. For adjusters, this reflects a familiar coverage defense strategy in construction defect claims, particularly where damage develops gradually and may not be discovered until years after project completion. The case underscores the importance of documenting when damage first manifests versus when it becomes apparent, as well as how courts interpret 'occurrence' and 'property damage' under CGL forms.
One of the more notable allegations involves Arch Insurance Company, which allegedly began defending the claim before withdrawing coverage. Midstream withdrawal creates operational and legal risk for claims teams, especially if reliance or prejudice arguments emerge. Adjusters managing defense obligations should note how such reversals may be scrutinized under bad faith standards.
The complaint also raises procedural compliance issues under Texas law. Allegations that some carriers failed to acknowledge or investigate the claim within statutory deadlines under the Texas Prompt Payment of Claims Act introduce exposure beyond indemnity. For claims professionals, this serves as a reminder that timeliness and documentation of claim handling activities can be as critical as the coverage analysis itself.
From a broader industry standpoint, this case reinforces how construction defect claims continue to test CGL frameworks. Progressive damage, overlapping coverage periods, and multiple carriers create complex allocation and defense challenges. Adjusters and coverage counsel will be watching closely for how the court addresses trigger theories, policy interpretation, and statutory compliance obligations.
