Wide Range of Project Experience

With almost three decades of experience in home remodeling, home repair and home renovation projects, you’ll benefit from our extensive knowledge – no matter what your particular project needs.


With OSB’s vetted team of consultants and designers, we are also available for consultations and project analysis. A separate but growing part of the business is to provide private, homeowner consultations – an hourly service where we assess your home and your ideas to estimate cost, explore feasibility and scope of remodeling projects, and help homeowners outline specific steps needed to achieve a proper remodeling job – one that is to code and will stand the test of time. When you need expert advice, we deliver. And when you need to get ideas on paper, we can develop CAD drawings to outline exact dimensions and layouts of your dream project.
