Our Design-Build Process

S.J. Janis provides end-to-end solutions for home remodeling through our design-build process, making us your single point of contact throughout the project. Our process goes as follows:

  • Initial conversation: We kick off your project with an in-depth discussion about your needs and goals for your remodel, ensuring your vision and budget align.
  • On-site meeting: Our senior design consultant visits your home to evaluate the existing space and discuss potential remodeling or expansion options to best meet your needs.
  • Design project development agreement (DPDA): After signing the DPDA, we take detailed measurements of your home, create floor plans and 3D renderings, and propose multiple layout options. We also discuss product selections and do a thorough walk-through with our team.
  • Fixed-cost construction agreement: You receive a complete construction agreement with a fixed cost, ensuring there are no unexpected expenses or changes unless you decide to modify the project.
  • Pre-construction conference: Before construction begins, we meet to discuss what to expect during the remodel. We provide a detailed project schedule to ensure smooth operation and on-time completion.
  • Construction phase: Regular weekly meetings with the project manager ensure open communication throughout the project, discussing progress and upcoming plans.
  • Project completion: We ensure your satisfaction with a final punch list and close-out meeting. We schedule six-month and one-year warranty visits to demonstrate our commitment to you as part of our “client for life” philosophy. Your transformed space is now ready to enjoy.

Collaborating from the initial consultation through project completion ensures seamless communication, minimizes delays, and helps us maintain the budget.
