Exquisite Homes LLC holds an impressive 5-star rating from 15 reviews. Customers frequently commend their attention to detail and professionalism. This contractor excels in creating stunning home additions that enhance both functionality and aesthetics. However, their higher volume of work may lead to longer wait times for initial consultations. 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 homeowners looking for premium quality home additions. It serves Renton, WA, and surrounding areas, with $150 to $400 per square foot pricing, and the honest trade-offs are potentially longer wait times for consultations.
