How Our Window Replacement Process Works: 4 Simple Steps

Replacing the windows in your Indianapolis-area home should feel straightforward, not stressful. At Modern Day Window & Door, we use a clear, four-step process that takes you from your first free consultation all the way through final inspection. Our certified installation team will be with you at every stage. Whether you're replacing a single double-hung window or upgrading every opening in your home with Andersen, Pella, or Marvin products, here's exactly what to expect.

1. Free In-Home Consultation
Schedule your free, no-obligation in-home consultation at a time that works for you. One of our window and door specialists will visit your home, measure your existing openings, evaluate your current frames for rot or structural issues, and review product options that match your home's style and energy-efficiency goals. We'll discuss frame materials including vinyl, fiberglass, composite Fibrex, and aluminum clad, and glass packages such as HP SmartSun and triple-pane upgrades. You'll receive a detailed, itemized quote before we leave. No pressure, no surprises.

2. Custom Product Selection
Once you're ready to move forward, we help you finalize your product selections from our authorized lineup of Andersen, Pella, and Marvin windows and doors. Choose from replacement window styles including double-hung, casement, awning, picture, gliding, and specialty shapes, or explore our full range of sliding glass doors, entry door systems, and Frenchwood door configurations. If you're working with a historic home, we'll discuss our window restoration and preservation options. All orders are custom-manufactured to your exact measurements, not off-the-shelf sizing.

3. Professional Installation
Your dedicated installation crew arrives on the scheduled date, typically within 2 to 6 weeks of your order. Our certified installers remove your existing windows or doors, prepare the rough opening, install your new units with precision flashing and sealing, and clean up the job site. We perform both insert replacements and full-frame replacements depending on the condition of your existing frames. Most single-room installations are completed in one day; whole-home projects are typically finished within two to three days.

4. Final Inspection and Ongoing Support
Before we consider the job complete, a project lead conducts a thorough walkthrough with you to inspect every installed unit for operation, seal integrity, hardware function, and interior and exterior finish. We'll explain how to operate and maintain your new windows or doors and answer any questions. Modern Day Window & Door provides manufacturer-backed warranties and post-installation support. We're available to address any issues or service requests across the greater Indianapolis and Fort Wayne areas.

Window Replacement FAQs

How long does the window replacement process take from consultation to installation?

From your initial consultation to completed installation, most projects take between 3 and 8 weeks. The consultation and selection phase typically takes 1–2 weeks, and custom window manufacturing generally requires 2–6 weeks depending on the product line and configuration you choose.

Do I need to be home during the installation?

Yes, we ask that a homeowner or authorized adult be present for the duration of the installation. This allows our team to address any on-site questions and ensures you can participate in the final walkthrough inspection.

How disruptive is window replacement to my daily routine?

Most homeowners find the process minimally disruptive. Our crews work efficiently, typically completing individual rooms in a few hours. We protect your interior with drop cloths and remove all debris before leaving. Expect brief periods where an opening is exposed to outside air during the swap.
