For Builders & General Contractors

Window & Door Subcontracting for the Twin Cities

Partner with a licensed window and door specialist who keeps your projects on schedule. Full-service ordering and installation or skilled install crews — serving GCs across the metro.

Unlike full-service exterior companies that spread across roofing, siding, and painting, JMB Builders focuses exclusively on window and door installation — making us the specialist general contractors call when the window scope needs to be done right.

Subcontracting questions, answered

Do you work as a window and door subcontractor for general contractors?

Yes — it's a core part of our business. Builders and GCs across the Twin Cities bring us in for window and door scopes on new construction, renovations, and insurance projects. Choose full-service (we measure, order, and install) or installation-only (you supply, we install).

Are you licensed and insured?

Yes. JMB Builders is a licensed Minnesota residential building contractor (MN Lic. No. BC809005) and fully insured. We're happy to provide certificates of insurance and references from GCs we work with before you commit.

Can you keep up with new construction and multi-home schedules?

Reliable scheduling is the reason GCs keep calling us back. We commit to dates we can hit, communicate early if anything shifts, and show up prepared — so the window scope never becomes the reason your build stalls.

Do you handle insurance and renovation window scopes?

Yes. Insurance-related window and door repairs are a niche most full-service exterior companies avoid, and one we specialize in. We work to scope documentation and deliver the workmanship quality adjusters and homeowners expect.
