Expand your living space and enhance your home’s value with our custom home additions. At S.J. Janis Company, we seamlessly integrate new spaces into your existing structure, ensuring that every addition is a perfect blend of functionality and aesthetics.


Timelines depend on the size and scope of your project. Most remodels and additions move through several phases – initial consultation, design, permitting, and construction – and larger projects can take several months from start to finish. Because S.J. Janis Company manages design, permitting, and construction all under one team, you get a coordinated schedule with weekly project manager updates, so you always know where things stand.
Cost depends on the size, scope, and finishes of your project — every home and vision is different. S.J. Janis Company starts every project with a complimentary design consultation where the Director of Design visits your home to understand your goals and review the scope of work, which is where you’ll get a realistic sense of budget for your specific project.
S.J. Janis Company has been transforming homes since 1951, with more than 1,400 completed projects and over 115 industry awards, including being a Guildmaster Award winner for nearly two decades running. Their design-build approach means one dedicated team – from the Director of Design through construction – handles your entire project, with weekly project manager meetings to keep you informed, and partnerships with top-tier vendors like Kohler, Cambria, and Plato WoodWork to ensure quality materials throughout.
Choosing the wrong contractor often means delays, budget overruns, and disjointed communication between designers and builders. S.J. Janis Company solves this by keeping everything under one roof — since 1951, our in-house team of designers, consultants, and craftspeople has completed over 1,400 home projects and earned 115+ industry awards, so you’re never left coordinating between separate firms or guessing who’s responsible for what. From your first consultation, our Director of Design personally visits your home to understand your goals, giving you a single point of contact you can trust from concept through completion.
DIY or piecemeal remodeling often runs into poor planning, underestimated budgets, and permitting headaches — problems that turn a dream project into a stressful one. S.J. Janis Company removes that risk with our design-build approach: one team handles architectural planning, interior design, permitting, and construction together, so nothing falls through the cracks between separate contractors. With weekly Project Manager updates and a dedicated team managing your construction calendar, you always know what’s happening next – and you get the peace of mind of a Guildmaster Award-winning team (2007–2025) backing your project.
