We offer full service design and construction needs. Which encompasses the clients design through collaboration, experience, and quality work. Our service ranges from interior renovations, additions, kitchens, basements, and bathrooms to trim work, custom cabinetry, tables, bar tops, doors and windows. Our owner and operator, Ryan has over twenty -years experience in the construction industry. His background in architecture, design, construction, and project management sets him apart from other competitors. He'll tell his clients, "it all starts with a sketch, from there anything is possible". For your next project, go with Indigo!

"The exterior door installation went well and was completed on time. Ryan’s helper called out and did not come the day the job was scheduled but Ryan was still able to complete the job as scheduled, alone. We decided to use Indigo because Ryan was more knowledgeable about door installation and the types of doors available that we could purchase. His estimate included plans to carefully remove our relatively new storm door so he could re-install it after the new exterior door was finished. Ryan was very communicative and helpful to us to get the job done right. We will likely use Indigo’s services again when we have another project. Muriel and Ray"
