Sunrooms questions from Hillsboro homeowners
Does MDR Build do sunrooms in Hillsboro, MO?+
Yes. Hillsboro, MO is part of our regular service area — the Jefferson County seat, and roughly 13 miles from our imperial shop from our shop in Imperial, MO. Enjoy the view year-round with a custom sunroom addition.
Can a sunroom be used year-round in Hillsboro?+
A three-season room is glass and screen for spring through fall; a four-season room is insulated, conditioned living space you use through a Missouri winter. We walk Hillsboro homeowners through both, including foundation, roof tie-in and StruXure or Fenetex options for shade and screening.
Who pulls the permits for sunrooms in Hillsboro?+
We do. Permit requirements and inspection steps are set by your local Jefferson County jurisdiction, and handling them is part of the job — we submit the paperwork, schedule inspections and meet the inspector on site so you are not chasing the Hillsboro permit office.
