Cumulative Rating: ★ 4.7-4.9 (based on 900+ reviews)

Service Areas Mentioned: Plano, Dallas, Frisco, McKinney, Allen, Carrollton, Richardson, Flower Mound, Prosper, Irving, Lewisville, Garland.
Common Review Themes: Positive reviews consistently praise individual project managers and designers by name (Jaime, Joe, Blake, Tiffany) for communication, responsiveness, and design help, and many clients report using them for multiple projects over the years. Recurring positives include craftsmanship quality and a structured, professional process. Recurring negatives — visible mainly on Angi/HomeAdvisor — center on scheduling delays, inconsistent experiences depending on which project manager is assigned, and pricing being on the higher end. A handful of reviews cite serious disputes over contract terms and liens on unfinished work, though these appear to be a minority relative to the overall volume of positive feedback.

USI Design & Remodeling
1560 E Southlake Blvd Ste 100, Southlake, TX 76092, United States | (972) 206-0750

Service Areas Mentioned: Southlake, Dallas, Plano, Frisco, Carrollton, Richardson, McKinney, Allen, Arlington, Irving, Coppell, Grapevine, Flower Mound, Lewisville.
Common Review Themes: Client feedback highlights the design team's guidance (multiple reviews name specific designers), transparency around pricing with no hidden upcharges, cleanliness and respect for the home during construction, and projects finishing on time or early. Reviewers frequently mention feeling like they were part of a collaborative process rather than just customers. There's less visible negative feedback in available snippets compared to some competitors, though the sample of accessible reviews was smaller, so this should be verified directly.

MTR Contractors
1647 Witt Rd #101, Frisco, TX 75036, United States | +1 972-432-7011

Common Review Themes: Reviews describe MTR as professional and detail-oriented, with specific praise for garage remodels and outdoor kitchen/palapa restoration work. Ratings are consistently high (4.6–5.0) across platforms, suggesting strong satisfaction among the smaller pool of reviewers, but the lower overall review count means less data to identify recurring complaints.

There isn't enough visible negative feedback to identify a consistent complaint pattern, likely due to the smaller review sample.
