Oak Hill’s craftsmanship truly impressed us. They went above and beyond to ensure every detail was perfect, often coming back to touch up areas that needed extra care. Their dedication to quality and use of high-end materials made all the difference in our remodel.
Lisa M.
Chris completely transformed our awkward, inefficient home into a modern, beautifully functional space, and his 3D renderings and walkthroughs captured our style so perfectly that we never needed an interior decorator. Working with Chris was a pleasure from start to finish, and we would recommend him without hesitation.
Stephanie M.
We worked with Chris on three phases of a challenging, multi-part renovation, and he transformed a disjointed, irregular home into a contemporary, functional space while being a pleasure to work with throughout, which is why we recommend him without hesitation and look forward to working with him again.
Rob M.
We just had a bathroom renovation with Oak Hill, and Chris Guay is an amazing designer and builder. His vision, passion, and work ethic kept my wife and me fully involved, and the use of his client portal to track every step made the process clear and organized. With Chris at the wheel, we felt confident we would reach the finish line completely happy.
Frank K.
Chris and his team did outstanding work remodeling our basement, completing the project in under two months while maintaining daily communication and consistently going the extra mile, and we will definitely be working with him again.
