Windows & Doors | OBM Construction and Custom Homes
Replacing windows and exterior doors improves your home's energy efficiency, security, appearance, and comfort. In Michigan's climate (Zone 5-6), properly insulated and sealed windows are essential for managing heating costs and indoor comfort.
We install both replacement windows (which fit into existing frames) and new-construction windows (which require removing the existing frame and trim). The right approach depends on the condition of your existing frames, whether you want to change window sizes, and your budget. We explain the difference and recommend the best option for your situation.
Energy performance matters in Michigan. We recommend windows with Low-E glass, argon gas fill, and U-factors appropriate for Climate Zone 5-6. Better performing windows cost more upfront but reduce heating and cooling costs over the life of the window. We present options at different performance and price levels.
Flashing around windows and doors is the single most important detail in any installation. Improperly flashed windows are the leading cause of water intrusion in residential construction. We follow manufacturer flashing requirements using compatible products — sill pan, side flashings, head flashing, and integration with the house wrap system.
Our window and door proposals include a complete schedule listing every unit by location, size, type, material, glazing specification, hardware finish, and screen type. This schedule ensures you get exactly what you approved and eliminates ordering errors.

Frequently Asked Questions
Q: How much does window replacement cost?
A: Window replacement costs in Southwest Michigan typically range from $400 to $1,200+ per window installed, depending on size, material (vinyl, fiberglass, wood), and performance level. We provide pricing per window based on your actual sizes and selections.
Q: How many windows can you replace in a day?
A: Our crews typically replace 8 to 15 windows per day depending on size and accessibility. A whole-house window replacement for an average home takes 1 to 3 days.
Q: Do new windows qualify for tax credits?
A: The federal tax credit for energy-efficient windows ended for products placed in service after December 31, 2025. Utility rebate programs may still apply to qualifying windows — we point you to current programs during your consultation and provide the manufacturer documentation needed for any rebate application.
Q: What window brands does OBM install?
A: We work with major manufacturers including Andersen, Pella, Marvin, and Milgard, as well as quality mid-range brands. We recommend products based on your performance requirements, aesthetic preferences, and budget rather than brand loyalty.
Q: Should I replace all my windows at once?
A: Replacing all windows at once is typically more cost-effective than phasing the project, as mobilization and labor setup costs are spread across more units. However, we can phase the project if budget requires it.
