With a stellar rating of 4.9 based on 98 reviews, Preferred Construction is a standout in Knoxville for home additions. Customers praise their attention to detail and excellent communication throughout the project. They are particularly noted for their ability to handle custom designs. However, as the leading provider, their availability may be limited due to high demand.
Done Right Home Improvements, LLC holds a 4.9 rating from 31 reviews, making them a promising choice for home additions in Knoxville. Customers appreciate their affordability and quality workmanship. They excel in providing good value for those on a budget. However, the limited number of reviews may mean less certainty about consistency over time.
Green Home Installations has a solid rating of 4.6 from 150 reviews, indicating a strong reputation in Knoxville. Reviewers highlight their eco-friendly approach and quality craftsmanship. They are ideal for homeowners looking to incorporate sustainable practices into their additions. However, some customers have noted delays in project timelines, which could be a concern for those on tight schedules.
Buckhead Construction Company has a rating of 4.6 from just 18 reviews. This suggests a promising but unproven track record. Reviewers appreciate their professionalism and quality of work. However, with such a thin review base, potential clients may find it hard to gauge their reliability and consistency. The review base is still thin, so we read the rating as promising rather than proven and weighted it accordingly. Most of what reviewers hire it for is general home construction. It serves Knoxville, TN, with $80 to $250 per square foot pricing, and the honest trade-offs are thin review base and limited customer feedback.
