ABOUT US
Sierra Unlimited Construction was born of a desire to deliver the highest quality residential projects. After many years of experience in renovation, Jim recognized that the customary process was inherently flawed and cumbersome for both the client and the contractor. The burden was on the client to find a designer, source materials, find a contractor and pull it all together.
That problematic process is what fueled the vision for a more holistic, fully-connected approach designed to relieve the stress and uncertainty of major home renovations. We guide you through the design and selection process, so you’re not overwhelmed. We believe in listening first. Design is a process, not a product. We don’t push our vision on our clients–we help them realize theirs.
Knowing that the highest quality results come from controlling the entire process, Jim brought together his decades of construction experience with his own custom fabrication shop and in-house design. One-stop shop.
We are a family business serving families. Together, we create solutions.
We build relationships.

On his mother’s side, his uncles are all in construction, and his great grandfather was one of the ironworkers who built the Peace Bridge. While his friends played football, Jim worked with his dad and was a seasoned veteran by the age of eighteen.
Jim lives in Buffalo and has been married for 16 years to his High School sweetheart, and they have 3 boys. He enjoys snowboarding and road course racing.
JULIE DEUBLE
Julie joined Sierra Unlimited as Lead Designer in 2014. She and Jim had worked on a number of projects together, and she saw the issues inherent in the typical renovation process from her perspective as a designer. Frustrated with the limitations and quality of production cabinetry and the lack of truly skilled contractors to execute her designs, she started working with Jim to design truly custom projects.
With a BFA in Interior Design and a Master’s degree in History, Julie brings special knowledge and skills to older and historic home renovations.
Client Testimonial
Having spent 10 years in the kitchen and bath industry working for a cabinet manufacturer, I can attest to the fact that that Sierra Unlimited Construction’s Arbor Craft cabinets are extremely well made and well finished. They are truly custom grade. Their design options and accessory selections are vast. Julie is their talented designer who puts it all together in the most attractive and functional way. Her sense of style is keen and she is sensitive to every client’s specific needs.
Client Testimonial
Julie was and continues to be an amazing resource. She provides her expertise and experience when planning all the various details to a space. She helps clients to itemize and think through all the different options/fixtures/paint colors/styles/etc. for every aspect of a room. Further, she helps to show how an area or design will fit into the overall look of a project. I could not be happier to have had Julie as a resource. I truly appreciate all the time, attention, and detail she put into our project to help make our dream space a reality. I highly recommend Julie, the Sierra Unlimited Construction team, and Arbor Craft Cabinetry for any and all remodeling needs.

Client Testimonial
I found Julie from a home magazine I saved two years before we even started thinking about our project. She was everything the article said & more. She guided us through a major master bath renovation that exceeded our expectations in every way. She was instrumental in helping us choose cabinetry, counter surfaces, tile, and fixtures. sinks, tub, & shower glass. We were so thrilled with the results that we then began an even more involved renovation of the entire kitchen/dining/sunroom area of our home. These plans changed many times until they evolved into something that we absolutely love. She was patient & really listened to what we wanted as well as making suggestions that helped bring this vision to life. She guided us through the selection of cabinets, appliances, granite, fixtures, flooring, lighting, & windows. I highly recommend her & am so happy I saved that article!
