Sunrooms questions from O'Fallon homeowners

Does MDR Build do sunrooms in O'Fallon, MO?+

Yes. O'Fallon, MO is part of our regular service area — one of Missouri's largest suburbs along I-64/Highway K, and roughly 43 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 O'Fallon?+

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 O'Fallon homeowners through both, including foundation, roof tie-in and StruXure or Fenetex options for shade and screening.

Who pulls the permits for sunrooms in O'Fallon?+

We do. Permit requirements and inspection steps are set by your local St. Charles 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 O'Fallon permit office.

How do I get a sunrooms estimate for my O'Fallon home?+

Call (314) 706-2721 or send a request through our contact page. We come out to the property in O'Fallon, MO, measure, talk through materials and layout, and put a written scope and price in front of you. Estimates are free and there is no obligation.

How is pricing handled?+

Everyday fair pricing — no gimmick promotions or countdown discounts. You get one written number for the scope we agreed on, with allowances spelled out, so the O'Fallon project you approve is the project you pay for.

Do you use subcontractors on O'Fallon projects?+

Our own crews carry the core of the work. Licensed specialty trades — electrical, plumbing, mechanical — are brought in where the code requires a licensed installer, and we coordinate and inspect their work.
