In a separate 2026 review, a customer praises the job of modifying the soffits on their gable dormers, writing that Jay provided a clear understanding of the work scope upfront and that the crew worked efficiently, which led to a shorter time frame than expected.

A 2026 review described a 15x20 deck project that stayed on budget and was completed on time, with the team keeping the job site clean every day.
